Well, that too. Lot’s of people work with heavy machinery. A jackhammer counts too. It’s a way for the person to have another reason not to work, because corporations, road crews, and factories don’t care if you have a sniffle… it also counts for recreational stuff like 4wheelers, boats, and snowmobiles.
Good rule of thumb for a bare minimum, if you pick machinery up with one hand and think "Ooh, that's got some heft to it!", Then it should be treated as heavy machinery. Motors really don't need to be that big anymore to be able to cause significant damage.
@@superme63 To be fair, I don't think there's that many people taking the safety of smaller motors for granted.

Resin actually gets stuck into hollow parts if they don't have holes! Kinda like how you can dip the neck of a full bottle in water and it doesn't empty, parts without holes can't empty while printing. So printing a hollow ball would end up being full with uncured resin and be a paintball lol
i know right??! in an earlier podcast they talked about how cody had the FBI tell him to take down some of his videos on TNT and explosives in general. would love to hear his story on that!
my 2 cents about resin printing: it takes so long mostly because it has to peel each layer off the bottom of the print bed. On my resin printer, each layer can take something like 8 seconds to 'cure' (enough for it to keep its shape during the next part), but between every single layer, it needs to pull the entire part up off the bottom of the vat, and then move it back down to the appropriate layer height. This process takes around as long as the cure time, and if it were not needed, you could get away with shorter cure times, as there would be way less mechanical forces the part would need to resist between layers. There have been some attempts to work around this, with mixed results. One simple solution is to use a top down printer, where the light is shining on the resin from above, but this requires either a ton of resin to sit in the vat at all times, or some secondary liquid that is denser than the resin, and won't mix, and this also can cause other issues, like the resin being too viscous to cover the entire print every layer, before the curing begins. Another solution I've seen uses pressurized air, and an oxygen-permeable membrane, which creates a boundary layer at the bottom of the vat where the resin doesn't actually cure, and then you can actually just pull the print out of the vat as it cures. I remember this having its own set of issues, maybe around controlling the thickness of that boundary layer, and the general added complexity from all the new tech in there. It may or may not have also needed a special resin to produce that effect with oxygen.

Probably answered already in the comments, but the reason you shouldn't leave uncured resin in models is when you leave uncured resin trapped inside models, it tends to cause the models to crack- I can't remember quite why but it might have to do with the fact that resin expands slightly when it cures (which is why you have to account for that expansion if you want to make good ball joints or push fit parts) and I think the resin on the inside will slowly cure and then the expansive pressure cracks models. Having to add drain holes is another obnoxious part of resin printing, because unless you can miraculously place that drain hole where it isn't visible at all, you have to then fill and smooth the drain hole to look flush with the surface, or match a given texture that the drain hole goes through. There's also an issue from printing entirely solid things, and why you need to hollow- a similar thing happens with the model or what have you eventually cracking, but I've only noticed this with excessively t h i c c model parts, and I think the reason is that the deep inner parts cure at a different rate, leading to uneven cure and curing of the internals over time when the outer layers are already cured. I've printed some beefy stuff before without issue, its mostly just a waste of resin. That being said, I've had models that I included drain holes on and (mostly) properly drained that did end up cracking too- but I think that may have been overexposure from being unprimed and sitting in front of a window. Overexposure causes the resin to go brittle and shatter easily, which can lead to cock-ups during/after curing when thinner parts get overexposed making them easy to break- compounding this fact is that those thing parts are usually very snagging or jutting shapes, like swords, arrows, spikes, etc which are easily caught. Its why people recommend shifting around your parts during curing to ensure even curing but also minimal curing comparatively on those thin bits. I printed an ant once and all the legs ended up breaking off in a few days because they were so overexposed compared to the body, which took awhile.
I use to work at a Lowe’s, and the absolute lack of effort it takes to be allowed on a forklift is terrifying. I almost died from a poorly trained 18 year old nearly pinning me and a customer to the back of his pick up. That was my second day of work.
Yeah, when I was 19 and started working at a factory my boss just told me to get in the forklift, showed me what the different paddles did, and then made me lift a couple tons and drive it around, and putting it into storage some 10 feet up in the air etc. I have experienced dropping several tons worth of shit, like one time I was carrying something that was in a pallet and a little bit off center on the gravity, and I was driving around in the outside area of the factory and drove over a pothole with the tiny ass left wheel and I watched as all the shit slid off in slow motion. That's some serious disfigurement or death if anyone was around, I knew the pothole was there too but it was in a moment of inattention.
Same here I used to work at lowes all the training is for those who don’t know, is you do a short course on safety of forklift finish it in 2 days by yourself and then you get trained by a manager for 15 mins and then boom “certified” it’s very scary with some people. Many don’t understand weight differential and the pallets are always messed up. So it’s a very sketchy thing and easily drop loads of heavy product.
@@nall8387 I needed the money so the deal I made with myself was that if I almost died again I’d quit that day. No more scrapes with death happened, so I stayed for a little while longer.
heavy equipment: look into some of the mining equipment out there. my dad worked with a guy who accidentally ran his best friend (and the entire vehicle his friend was in) and didnt even notice until he got to his destination and was like "hey where's my guy?" because those vehicles are just so massive (though this did happen, like, at least 30 years ago, but accidents do still happen). i remember someone had dumped one of those tires out in the desert and we would play with it, and you could fit multiple people inside comfortably. it's horrifying.
I had a high school teacher propose to the school board that they force me to do the pledge of allegiance every day. Prior to this, I had simply been respectfully remaining sitting in silence and minding my business while others did their thing. The board ultimately told him no (duh, idk what he thought would happen). It was appalling.
I went to high school in the early aughts in Colorado, and by my junior year they made that creepy shit optional. My conservative white guy Spanish teacher HATED me for sitting through it 😂
omfg the part where the audio split i thought i started another podcast at the same time. ALSO i'm typing this comment while its still going on and i'm kinda impressed that i heard both conversations and typed this simultainiously.
I love this, I was listening to this podcast all day today. Got home and had a brand new episode to watch. Thanks for helping me live my best life Safetythird.
Driving forklifs where my first driving experiences. I worked construction with my uncle and he couldn't drive them because he was on pain meds. Whenever he did drive any of the tractors or forklifts he would always hit and then damage something on the property. I've been the counterbalance for his forklift exploits when something was heavier than the forklift itself.
I work at a place that 3D prints in metal! I print in CoCr using a EOS M270. It's around 15 years old but it does the job. It uses a laser to heat metal powder.
Does it use selective laser sintering (SLS), or something else? How does the material condition compare to traditional methods? I've heard that there are some laser hardening processes now being used on engine components for the F35. (edit: oh I just re-read the bottom sentence, you answered my first question already...)
I'm pretty sure the issue with metal 3D printing is that they use lasers for precision to fuse the metal and in order to achieve a powerful enough laser, you need higher voltage at a consistent rate, without compromising amp draw.
holy shit will talking about the wooden skateboard just unlocked a forgotten memory. that’s how i found out who any of these people are in the first place, I used to watch the channel he sent that board to a lot back in 2016 and thought it was the coolest thing ever so I looked up will’s channel
I used to work with DMLS printers, and the issues that would probably prevent consumer adoption is just the sheer amount of special equipment needed to do it safely. We had an industrial sieves to clear spatter from the good powder leftover from the print, we had special vacuums full of a concoction to pull powder out of the machine, you need a band saw to remove the print from the plate, you need a CNC machine to level your plate, etc etc... All of this while wearing respirators and going through hundreds of gloves. Plus they produce a massive amount of heat while in use. I hope they reach consumer level, but I'm not sure it will happen soon
43:30 a mass produced skateboard is typically around $100, and even though will isn't a professional board maker, as a small business $150-$200 is honestly a respectable price
on hollow resin prints: yes, there are cases when you hollow out an object and resin gets stuck inside, it is bad for the model and in most cases will lead to cracks in the model, from which the trapped resin will come out and get on stuff, to print proper hollowed resin models you need to add holes to it through which resin can flow out and air in
3d printing silicone is possible and there's some printers available using classical RTV (both 1 and 2) but it is also possible to print both UV and heat cured LSR
The phrase you're looking for is "economy of scale." Per-unit costs get lower when you increase capacity in part because your sunk costs are distributed over a broader revenue base. You don't want to build a factory to build just one unit unless your customer is willing to pay out the wazoo for that one unit.
The cost of work discussion is alive and well in 3d discords, the idea of having a job board in one sounds harmless but theres so many kids willing to make things for other kids for 15 bucks. I wouldn't even turn blender on for 15 bucks. Just talking about what the client needs is gonna take an hour. It's also done so much that it's actually dragging salaries down for actual freelancers.
Hey nerds, you mentioned being curious about metal 3D printing. Im a designer for 3D printed patient specific orthopedic implants. We print out of titanium using an electron beam melting machine. Extremely cool stuff!
Talking about lathes that can kill you, I used to run a huge lathe with a 30hp motor and a 4ft diameter chuck and we would turn parts weighing up to 2,000 pounds. No safety guards, no emergency stop. You start out being scared of it, but eventually develop a healthy respect for the fact that if you screw up you are dead or seriously injured. Never got complacent with it.
4 people who are obviously chaotic good. Just chilling. Man, I love it. Would love to hear more about your philosophies in life...because we see what some of that or how some of that imprints on your builds, and projects...would be interesting to hear more about your ideals in life. AND honestly, I am not sure that people in your positions know how much power you could have. Talking about war and the effects of politics on the world...and how we could have a better world. Likely completely outside of your wants or dreams for your channels but having a weekly or monthly or any podcast/ group chat about such things...could be powerful.
My gap year after school I worked in a warehouse and on stocktake they would lift me 4 pallet bays high to count cartons and then drive to the next bay and so on.. super sketch - the sway of the forks up that high is terrifying
57:35 i think it’s required to have the opportunity at the start of the day to do it, but students themselves aren’t required to, about half the main class i remember didnt
Not only do metal 3d printers exist, but they're commercially viable too. They work by having a thin bed of metal powder atop a plate, and a laser melts the shape of the current layer of the print, then another thin layer of powder is spread over the bed, and repeat. We use 3d printers to make steel parts at my place of work
As someone who has worked around a lot of heavy equipment (forklifts, front end loaders who's tires are almost as tall as me (6'4) screeners that throw dirt or rock out either side depending on what's in it that are as long as a dump truck) it's really easy to get caught in doing the wrong thing before you know it. I had a coworker back right into a semi and it busted the cab. Even though it's top speed is like 20, there is tons of power and weight behind it
More readily/fiscally available. Definitely seems like a cost prohibitive tech for individual use. I definitely wants one… also would love a 3d printer that uses granules that isn’t ridiculously large and expensive 🤷♂️ but I think the filament companies have the consumer hooked, or something….
Talking about people wanting to buy stuff from you that you made and way low-balling on the price: I had a friend recently ask me to print a 6 FOOT statue. I told him at least $1000 and he hasn't talked to me since lmao. To give you some context: my print area is roughly 7x7x11 inches. To print that volume takes roughly 100 hours, printing at good quality. Now scale that up to 6x3x3 feet. 6 x 3 x 3 is 54 cubic feet, but since it's a statue and not a solid chunk of plastic, some of that is going to be empty, so let's round down to 48 cubic feet. 48 cubic feet is 82944 cubic inches. My printer can print in 539 cubic inch chunks. It would take roughly 153.88 individual print jobs to print the entire volume of the statue. Times that by 100 hours each and we're looking that somewhere in the ballpark of 15388 hours of print time, or 641 days. Now you might say: "Justin, you could just not print out the chunks on the inside that are just perfectly square rectangular cubes." And you'd be right. But even assuming a reduction of half print time, we're still looking at 320.5 days of solid printing. This is an astronomical amount of time for me to be printing one project. That's TEN MONTHS of printing. Trying to factor in just the cost of my time would go way, way above $1000, not to mention the filament cost. Assuming it takes 80% of a roll of filament to print each 539 cubic inch chunk, and assuming half of 153.88 print jobs (because we can ignore the blank rectangular cubes on the inside), and each roll costs roughly $20, we're looking at roughly $1538.80 JUST FOR FILAMENT. In all honesty, I should have quoted him waaaaaaaaaaaaay high than $1000. Not to mention the endless sanding, gluing, and reprinting (because parts don't always come out right on the first go), I should have quoted closer to $10000. I think I low-balled myself.
The failed prints are kinda like failed coins or failed card prints It’s valuable to someone and it’s rare that’s all that matters, especially if you sign them and give them a certificate or something ‘official’ with it. Also I think Tsar Nicolas II would have cause a lot of dead children.
I just experienced an odd fever dream where I was watching this podcast and two separate conversations happened at once... One in the left speaker, one on the right... It was somewhat relaxing. Felt like a fly on the wall in a local pub.
@34:00 There is a 3D printing company that can print resin similar to silicone properties. Chromatic 3D Materials prints a 2 part urethane that can achieve a shore A 50 hardness.
WKUK has a great sketch about the Pledge of Allegiance: "...This is not a form of brainwashing. This is not a form of brainwashing. This is not a form of brainwashing. This really is the greatest country to ever exist." 😆
You NEED to get a Formlabs laser resin 3D printer William. The auto supports in their program is like magic, full auto supports work perfectly 99% of the time. They also automate the wash and cure end so 1 pair of gloves is all you need. They also have flexible resins to simulate silicone and tpu. Once you go Formlabs you never go back to cheap lcd resin printers
They already have laser metal printers they use them in F1 racing or car prototyping. They're 6 or 7 digit prices though, they work by melting beads (Steal, aluminum, titanium) usually. There are ones that are just 100% duty cycle welders attached to an arm.
That audio split was really interesting. I had to put on my headphones once it started but as i looked back and forth and tried to focus on each conversation it felt like it would get louder.
Had one of those metal cutting machines at my high school. A kid in my class thought he could hold the metal down through the safety grate with his fingers. He only had tendons and skin holding his fingers on afterwards.
The fumes from PLA are not toxic but it does produce VOCs. It's not a huge amount, comparable to a candle or cooking depending on the temperature but its def something you should avoid if you can. 12 printers in a room all printing though, might not be a huge risk but you should def have ventilation. I could show some deposits on some optics that were in a cabinet in a small room with a single printer. It's not great.
The split audio works surprisingly well for being able to understand both conversations at once, but for probably-autism-related reasons, different audio in different ears is absolute torture for me.

Probably answered already in the comments, but the reason you shouldn't leave uncured resin in models is when you leave uncured resin trapped inside models, it tends to cause the models to crack- I can't remember quite why but it might have to do with the fact that resin expands slightly when it cures (which is why you have to account for that expansion if you want to make good ball joints or push fit parts) and I think the resin on the inside will slowly cure and then the expansive pressure cracks models. Having to add drain holes is another obnoxious part of resin printing, because unless you can miraculously place that drain hole where it isn't visible at all, you have to then fill and smooth the drain hole to look flush with the surface, or match a given texture that the drain hole goes through. There's also an issue from printing entirely solid things, and why you need to hollow- a similar thing happens with the model or what have you eventually cracking, but I've only noticed this with excessively t h i c c model parts, and I think the reason is that the deep inner parts cure at a different rate, leading to uneven cure and curing of the internals over time when the outer layers are already cured. I've printed some beefy stuff before without issue, its mostly just a waste of resin.
That being said, I've had models that I included drain holes on and (mostly) properly drained that did end up cracking too- but I think that may have been overexposure from being unprimed and sitting in front of a window. Overexposure causes the resin to go brittle and shatter easily, which can lead to cock-ups during/after curing when thinner parts get overexposed making them easy to break- compounding this fact is that those thing parts are usually very snagging or jutting shapes, like swords, arrows, spikes, etc which are easily caught. Its why people recommend shifting around your parts during curing to ensure even curing but also minimal curing comparatively on those thin bits. I printed an ant once and all the legs ended up breaking off in a few days because they were so overexposed compared to the body, which took awhile.
I use to work at a Lowe’s, and the absolute lack of effort it takes to be allowed on a forklift is terrifying. I almost died from a poorly trained 18 year old nearly pinning me and a customer to the back of his pick up. That was my second day of work.
Yeah, when I was 19 and started working at a factory my boss just told me to get in the forklift, showed me what the different paddles did, and then made me lift a couple tons and drive it around, and putting it into storage some 10 feet up in the air etc. I have experienced dropping several tons worth of shit, like one time I was carrying something that was in a pallet and a little bit off center on the gravity, and I was driving around in the outside area of the factory and drove over a pothole with the tiny ass left wheel and I watched as all the shit slid off in slow motion. That's some serious disfigurement or death if anyone was around, I knew the pothole was there too but it was in a moment of inattention.
You mean your last day don't you?
Same here I used to work at lowes all the training is for those who don’t know, is you do a short course on safety of forklift finish it in 2 days by yourself and then you get trained by a manager for 15 mins and then boom “certified” it’s very scary with some people. Many don’t understand weight differential and the pallets are always messed up. So it’s a very sketchy thing and easily drop loads of heavy product.
@@nall8387 I needed the money so the deal I made with myself was that if I almost died again I’d quit that day. No more scrapes with death happened, so I stayed for a little while longer.
heavy equipment: look into some of the mining equipment out there. my dad worked with a guy who accidentally ran his best friend (and the entire vehicle his friend was in) and didnt even notice until he got to his destination and was like "hey where's my guy?" because those vehicles are just so massive (though this did happen, like, at least 30 years ago, but accidents do still happen). i remember someone had dumped one of those tires out in the desert and we would play with it, and you could fit multiple people inside comfortably. it's horrifying.
Big spinny lathes are by far the scariest thing... you literally instantly turn into minced meat if you touch them
podcast on a forklift is a banger idea
Thanks Will for showing me how to listen to 2 podcasts at once. Now I can clear my backlog out faster
I really enjoyed that split audio!
I had a high school teacher propose to the school board that they force me to do the pledge of allegiance every day. Prior to this, I had simply been respectfully remaining sitting in silence and minding my business while others did their thing. The board ultimately told him no (duh, idk what he thought would happen). It was appalling.
west Virginia vs barnette! idk why people still think it ok to force people pledge and things
I went to high school in the early aughts in Colorado, and by my junior year they made that creepy shit optional. My conservative white guy Spanish teacher HATED me for sitting through it 😂
I know audio splitting adds a lot of editing but please continue to do it, it's incredible!!!
It's really just 1 click
@@7JEO they have four mics and it's not like you click it once for the whole video, there's moments you need to choose
omfg the part where the audio split i thought i started another podcast at the same time.
ALSO i'm typing this comment while its still going on and i'm kinda impressed that i heard both conversations and typed this simultainiously.
it was great for me because im deaf in one ear
@@ramboturkey1926 lol you are going to have to switch your headphones for part 2 of choose your own adventure podcost
I love this, I was listening to this podcast all day today. Got home and had a brand new episode to watch. Thanks for helping me live my best life Safetythird.
Driving forklifs where my first driving experiences. I worked construction with my uncle and he couldn't drive them because he was on pain meds. Whenever he did drive any of the tractors or forklifts he would always hit and then damage something on the property. I've been the counterbalance for his forklift exploits when something was heavier than the forklift itself.
I work at a place that 3D prints in metal! I print in CoCr using a EOS M270. It's around 15 years old but it does the job. It uses a laser to heat metal powder.
Does it use selective laser sintering (SLS), or something else? How does the material condition compare to traditional methods? I've heard that there are some laser hardening processes now being used on engine components for the F35.
(edit: oh I just re-read the bottom sentence, you answered my first question already...)
The tree supports are very impressive. Some of them has art values for sure.
I'm pretty sure the issue with metal 3D printing is that they use lasers for precision to fuse the metal and in order to achieve a powerful enough laser, you need higher voltage at a consistent rate, without compromising amp draw.
That audio split was actually incredible. I want to try that
holy shit will talking about the wooden skateboard just unlocked a forgotten memory. that’s how i found out who any of these people are in the first place, I used to watch the channel he sent that board to a lot back in 2016 and thought it was the coolest thing ever so I looked up will’s channel
I used to work with DMLS printers, and the issues that would probably prevent consumer adoption is just the sheer amount of special equipment needed to do it safely. We had an industrial sieves to clear spatter from the good powder leftover from the print, we had special vacuums full of a concoction to pull powder out of the machine, you need a band saw to remove the print from the plate, you need a CNC machine to level your plate, etc etc... All of this while wearing respirators and going through hundreds of gloves. Plus they produce a massive amount of heat while in use. I hope they reach consumer level, but I'm not sure it will happen soon
My favourite podcast without a doubt!
43:30 a mass produced skateboard is typically around $100, and even though will isn't a professional board maker, as a small business $150-$200 is honestly a respectable price
the audio split is genuinely how i want to listen to this podcast
hey i just got forklift certified this content feels like it was made for me very cool
on hollow resin prints: yes, there are cases when you hollow out an object and resin gets stuck inside, it is bad for the model and in most cases will lead to cracks in the model, from which the trapped resin will come out and get on stuff, to print proper hollowed resin models you need to add holes to it through which resin can flow out and air in
3d printing silicone is possible and there's some printers available using classical RTV (both 1 and 2) but it is also possible to print both UV and heat cured LSR
Is it body safe?
@@LightPink some LSR are used for medical uses yes so it can be
The split audio part was hilarious
The phrase you're looking for is "economy of scale." Per-unit costs get lower when you increase capacity in part because your sunk costs are distributed over a broader revenue base. You don't want to build a factory to build just one unit unless your customer is willing to pay out the wazoo for that one unit.
The two conversation section was the absolute best.
Pledge of allegiance in my high school is basically some person on the intercom reading it with a little less than half the class murmuring along.
thats sad
@@ramboturkey1926 Most countries don't actually do one, the more you know~
@@GarrettX001 yeah instead the do weird school anthems
The audio split was perfect 👌
I only listen to podcasts at work so I can say I've listened to Safety Third exclusively while driving a forklift
The cost of work discussion is alive and well in 3d discords, the idea of having a job board in one sounds harmless but theres so many kids willing to make things for other kids for 15 bucks. I wouldn't even turn blender on for 15 bucks. Just talking about what the client needs is gonna take an hour. It's also done so much that it's actually dragging salaries down for actual freelancers.
Hey nerds, you mentioned being curious about metal 3D printing. Im a designer for 3D printed patient specific orthopedic implants. We print out of titanium using an electron beam melting machine. Extremely cool stuff!
Talking about lathes that can kill you, I used to run a huge lathe with a 30hp motor and a 4ft diameter chuck and we would turn parts weighing up to 2,000 pounds. No safety guards, no emergency stop. You start out being scared of it, but eventually develop a healthy respect for the fact that if you screw up you are dead or seriously injured. Never got complacent with it.
Omg that audio bit with spitting the channels was so funny. It messed with my head so much hahaha
You guys should look up the history of the pledge, very contriversal to say the least. Love the podcast!
That splitting was great :DD
I’m so glad I did a thing is a regular of the podcast now
4 people who are obviously chaotic good. Just chilling. Man, I love it. Would love to hear more about your philosophies in life...because we see what some of that or how some of that imprints on your builds, and projects...would be interesting to hear more about your ideals in life.
AND honestly, I am not sure that people in your positions know how much power you could have. Talking about war and the effects of politics on the world...and how we could have a better world. Likely completely outside of your wants or dreams for your channels but having a weekly or monthly or any podcast/ group chat about such things...could be powerful.
Holy sh!t! I went to school with her. I had no idea she was famous
There’s actually a lot of pretty good robust resins for MSLA printers now. Things have come a long way in a rather short period of time.
My gap year after school I worked in a warehouse and on stocktake they would lift me 4 pallet bays high to count cartons and then drive to the next bay and so on.. super sketch - the sway of the forks up that high is terrifying
Please make a podcast with nighthawkinlight
I loved the left and right channel 2 convo bit so much
57:35
i think it’s required to have the opportunity at the start of the day to do it, but students themselves aren’t required to, about half the main class i remember didnt
Not only do metal 3d printers exist, but they're commercially viable too. They work by having a thin bed of metal powder atop a plate, and a laser melts the shape of the current layer of the print, then another thin layer of powder is spread over the bed, and repeat. We use 3d printers to make steel parts at my place of work
As someone who has worked around a lot of heavy equipment (forklifts, front end loaders who's tires are almost as tall as me (6'4) screeners that throw dirt or rock out either side depending on what's in it that are as long as a dump truck) it's really easy to get caught in doing the wrong thing before you know it. I had a coworker back right into a semi and it busted the cab. Even though it's top speed is like 20, there is tons of power and weight behind it
Isn't metal 3d laser sintering already a thing?? Or is Alex talking about them becoming more readily available and popular?
More readily/fiscally available. Definitely seems like a cost prohibitive tech for individual use. I definitely wants one… also would love a 3d printer that uses granules that isn’t ridiculously large and expensive 🤷♂️ but I think the filament companies have the consumer hooked, or something….
Talking about people wanting to buy stuff from you that you made and way low-balling on the price: I had a friend recently ask me to print a 6 FOOT statue. I told him at least $1000 and he hasn't talked to me since lmao.
To give you some context: my print area is roughly 7x7x11 inches. To print that volume takes roughly 100 hours, printing at good quality. Now scale that up to 6x3x3 feet. 6 x 3 x 3 is 54 cubic feet, but since it's a statue and not a solid chunk of plastic, some of that is going to be empty, so let's round down to 48 cubic feet. 48 cubic feet is 82944 cubic inches. My printer can print in 539 cubic inch chunks. It would take roughly 153.88 individual print jobs to print the entire volume of the statue. Times that by 100 hours each and we're looking that somewhere in the ballpark of 15388 hours of print time, or 641 days. Now you might say: "Justin, you could just not print out the chunks on the inside that are just perfectly square rectangular cubes." And you'd be right. But even assuming a reduction of half print time, we're still looking at 320.5 days of solid printing. This is an astronomical amount of time for me to be printing one project. That's TEN MONTHS of printing. Trying to factor in just the cost of my time would go way, way above $1000, not to mention the filament cost. Assuming it takes 80% of a roll of filament to print each 539 cubic inch chunk, and assuming half of 153.88 print jobs (because we can ignore the blank rectangular cubes on the inside), and each roll costs roughly $20, we're looking at roughly $1538.80 JUST FOR FILAMENT. In all honesty, I should have quoted him waaaaaaaaaaaaay high than $1000. Not to mention the endless sanding, gluing, and reprinting (because parts don't always come out right on the first go), I should have quoted closer to $10000. I think I low-balled myself.
The failed prints are kinda like failed coins or failed card prints It’s valuable to someone and it’s rare that’s all that matters, especially if you sign them and give them a certificate or something ‘official’ with it.
Also I think Tsar Nicolas II would have cause a lot of dead children.
I just experienced an odd fever dream where I was watching this podcast and two separate conversations happened at once... One in the left speaker, one on the right... It was somewhat relaxing. Felt like a fly on the wall in a local pub.
@34:00 There is a 3D printing company that can print resin similar to silicone properties. Chromatic 3D Materials prints a 2 part urethane that can achieve a shore A 50 hardness.
Tungsten cubes were briefly very valuable iirc, all the nft bros got into it because cube
WKUK has a great sketch about the Pledge of Allegiance: "...This is not a form of brainwashing. This is not a form of brainwashing. This is not a form of brainwashing. This really is the greatest country to ever exist." 😆
I love the audio split!
You NEED to get a Formlabs laser resin 3D printer William. The auto supports in their program is like magic, full auto supports work perfectly 99% of the time. They also automate the wash and cure end so 1 pair of gloves is all you need. They also have flexible resins to simulate silicone and tpu. Once you go Formlabs you never go back to cheap lcd resin printers
i think i unlocked an additional % of my brain listening to the split LR audio feed bit
I'm already seeing William making like, a podcast with left and right audio, and then counting the podcast as two.
Wonderful Blue Steel @ 38:32
They already have laser metal printers they use them in F1 racing or car prototyping. They're 6 or 7 digit prices though, they work by melting beads (Steal, aluminum, titanium) usually. There are ones that are just 100% duty cycle welders attached to an arm.
Keep doing the split audio channels thing, it actually helped with the clarity
Great podcasting guys two conversations
That audio split was really interesting. I had to put on my headphones once it started but as i looked back and forth and tried to focus on each conversation it felt like it would get louder.
Had one of those metal cutting machines at my high school. A kid in my class thought he could hold the metal down through the safety grate with his fingers. He only had tendons and skin holding his fingers on afterwards.
The limitation with resin printers is also thermal.
I really loved the audio split bc I'm wearing earbuds!
when you split the audio channels my poor brain was struggling to take in both conversations simultaneously.
The fumes from PLA are not toxic but it does produce VOCs. It's not a huge amount, comparable to a candle or cooking depending on the temperature but its def something you should avoid if you can. 12 printers in a room all printing though, might not be a huge risk but you should def have ventilation. I could show some deposits on some optics that were in a cabinet in a small room with a single printer. It's not great.
happy you have a new content creator to lift up
The split audio works surprisingly well for being able to understand both conversations at once, but for probably-autism-related reasons, different audio in different ears is absolute torture for me.
