Mico Menta yep. Was coming to comment something similar. You can see that the load was yanked up and then stopped, causing the load to be relieved from the hook while the inertia carried it up. And then when the load fell back down, the hook broke. This is because the hook was under a much higher load than just the weight of the load alone. There are much more controlled (and not to mention less dangerous) ways of testing the breaking point of a material and measuring the weight at breaking point.
Agree. 1 minute in and I can't take any more, it's obnoxious. Might try to finish with sound off, but based on other comments this is just an infomercial. :/
The PLA actually snapped under probably a couple tons of FORCE. The jerk caused way more force than the weight of the tire. Your method doesn't work, it causes too much jerk. Nice try though. Seems like you want us to buy your nylon/polycarbonate print-bed glue and filament.
@@SunnyDaysRFun I would say no still. You can't apply the same amount of force with every test that way. It's too inconsistent. If you could guarantee that there is the same exact jerk and force every time you did it, then it would be fair.
sorry but this test is flawed when testing the pla the load you put on it was bouncing witch would make the load up to 2 times more and the rest of the test didnt bounce as bad.
Watching the video it shows that the pla got shock loaded and when you shock load something you cannot get an accurate measurement of its strength. I would recommend you do a revisit on this video and not use a forklift but more of a winch or a come along to achieve a more stable way of pulling it up
I'm calling BS on the hook test. What you saw was more a test of shear strength than it was lifting strength. If they had wanted to show how much weight it could lift before failure they would have made a figure 8 type with the center at the same cross section as the outside cross section of the wall of one of the loops, somewhat like this 0-0, then lifted weight until the center lug or one of the loop walls failed. A test best performed in an enclose safety booth with a hydraulic expanding ram and short attachments to limit flailing at failure.
@@SunnyDaysRFun They didn't even use a tensile meter. They only put weights in a tire and jerked it around. And they're in a shop of all things. You'd think they would have a tensile meter. All that jerking around multiplied the actual weight each 3D printed hook endured and randomize it based on how hard they pulled it at the time, and when they pulled it while the tire was swinging. I can not think of a more inaccurate test. They are targeting the wrong market here with the wrong strategy to sell adhesion glue..
I'm very into what you've done for us by testing these! As a few people stated before, the jerk on the hooks cause a huge range of error in the tests. a better way would be to create a sled, lift it, and then load it consistently. Then- to reliably test tensile, you should make a hook that is super beefy on both ends, with a consistent diameter cylinder in the middle- that will give you a predictable break zone in every hook, and will be pure tension. In the examples you printed, the failure was part bending, part tension, and probably part shear. I'd also love to see pure shear tests, since I get a lot of small gears on my printer failing along layer boundaries. Although that would be a much more detailed video, since layer temperature and bonding time can have drastic effects on shear. Still, these kinds of demonstration videos with consistent tests are hard to find. I was surprised that PLA outperformed ABS, and was impressed by the PC. Any change you'd try something with carbon fiber in it to see if it actually makes a difference? Thanks!!
there is a difference between degrading a material and temperature resistance, pla wont degrade for decades if left outdoors in non extreme sunlight. This is not an issue with the materials biodegradability like suggested instead its to do with its temp resistance. the other thing is that stress test was bouncing really bad, you could be having 2 or 3 times the quoted force due to the bouncing.
its not a bad test and considering they used the same method with all the different types on material. It still shows how much stronger one is from another.
@@DonnyAngler using the same method doesn't mean an accurate test. The way they tested the materials were very unprofessional. It doesn't make sense. You could clearly see them trying to break the PLA. Whereas with nylon and up, being gentle with the lift for sudden jerk or fast acceleration. Also the numbers don't really add up. PLA rated 7,250lb psi failed at 285lbs, ABS 4700lb psi 285lbs, nylon 7000lb psi 445lbs. Really...?
LOL where did i say it was accurate? I said it shows the different strength of the different types of filament compared to each other. Depending on your print settings and how you print them can greatly alter the strength of a print. Making it much weaker or stronger.
"It's not a bad test"? LOL oh yea this test is good enough. I think you should go look up the definition of the word 'test'. The numbers and the test results are all over the place. You should look up how to properly test a 3d filament. Can't believe you replied with confidence.
Engineering design point of view: Wear resistance is much more important on gear designs (I am only mentioning about it because you showed examples) Tensile strength comparison under static load (or may be dynamic? We couldn't see how did you load it and I think that forklift was a bit too fast on lifting) comparison was great and I will certainly keep this in mind while considering. Thank you for the video
Yup the stress was increased by erratic operation of the forklift. You didn’t feather the lever but jerked the lever which caused the force to spike up sharply breaking the hook prematurely.
Thank you. The bouncing made it more of a real world example and would cause a more brittle material to fail sooner. Although, in my engineering classes, you use a different shape to do strength and yield tests. But small errors in the surface can cause stress points that can lead to failure. It is not desktop, but I am about to order parts in Stainless Steel 3D printed. It has laser that melts thin layers of fine grains. About 95% solid I am told.
Wow that background music was seriously distracting.. 2 bars just repeated over and over... coupled with the background noise from operating machinery and the poor voice recording and this was quite, quite dire.
Stopped the video at 5:34 Dollar store glue sticks work great on print beds. Also, regarding your printer in the background, what kind of print project requires a 300 km/h travel speed?
What? Other than the like 5 second "hey buy our printers" at the literal end of the video, there wasn't any ADVERTISEMENT (as you liked to put it all in caps) that I noticed. When they mentioned that they used nylon in their printers, that wasn't them advertising anything, just pointing out that nylon is strong enough to be used in gears for industrial applications. I hate blatant "buy my shit" videos as much as anyone else does, but this video was literally 99.9% straight info, and 0.1% "btw get some free shipping on an order." Care to elaborate on the ADVERTISING you saw? This comment was paid for by Starbucks™, The Coffee You Crave™
The WHOLE Video is ad when you brand it with your store name and refer to everything as OUR in the video. Read the desc below the vid where there is a store link. This whole video was an ad. Jackass.
21:9 Gaming who took a whizz in your cornflakes? I didn't even notice that they said "our" filament, so what? Not that it matters, the plastic they're talking about are the same as everyone else's in terms of strength and printing, I would assume. The information is exactly the same for whatever brand of filament. You're getting upset enough to call me a jackass over almost nothing. A link in their description? Has nothing to do with the video, 97% never even look at the description. I didn't get the impression of being advertised to in the video until literally the last 5 seconds or so, which again, most people don't watch to the very end of a video. Did I insult you or call you names? I'm not quite sure why you felt the need to insult me. Is it because I capitalized ADVERTISING? I just wanted to grab attention like you wanted to when you capitalized it.
PLA facts are false. It won't just degrade under sunlight and/or an outdoor environment. It has to undergo the right process for it to biodegrade correctly. The conditions aren't correct at a regular landfill either. It has a low glass transition temperature which is why if you leave something in the car or warm area it will start to collapse (the thinner the walls the weaker the structure). I've had multiple models sitting on my dash and there has been no degradation. Just look up PLA and sunlight or UV degradation.
Thank you for your feedback. PLA is a great material, but it is both thermally unstable and biodegradable. Thermal instability leads to unpredictable behavior (i.e. deformation) in outdoor environments, especially those with strong sun exposure. Therefore we would not recommend using it in load bearing applications. You are correct in that to biodegrade completely, it should be composted, which can occur within 30 or so days. Otherwise PLA is a fantastic material, especially for schools!
Right the biggest thing I was getting at was that the thermal problems are the main concern with PLA ;) . I know the windshield also has UV protection so even though I have some models printed in PLA on my dash, they haven't had any real noticeable change (I expected the black pigment to start fading and it didn't, but that would be a filler problem more than a material problem right?). According to this site (www.filabot.com/blogs/news/57233604-the-misleading-biodegradability-of-pla) and many other articles I've read, biodegradability isn't a concern. PLA is great in many respects. I even bought the sheets of Kapton from your site to replace the ones I use for my bed because I use it a lot. I also use the Kapton for Pet+ and TPU filaments and it works great! I'm not a fan of ABS and rarely use it.
I fixed my mailbox with PLA for the flag (it is a really big piece) and after two years in 85-105f temps, full hot afternoon sun, raging 80+ percent humidity, rain, 0f cold, snow, hail, and sleet and it still looks like it did when I put it up.
Yeah I actually have Fly Trap printed in PLA and it has sat outside in direct sunlight all summer and all winter and there are no noticeable differences in it other than the color but that is just because it has dirt and fly droppings on it. I think really PLA should be looked at more as a prototyping Filament because it is cheap, prints easy, and is relatively strong. But also it should be looked at in a case by case basis. There are some parts that PLA would be great at, but others there are clearly better suited materials.
I have a PLA part that i printed 3-5 years ago, that is in the sun, rain ('an arm for an anemometer), and i live in tropical area, so sun all year, rain very often. I also used PLA for at least 2 years in an aquarium, as fittings for a pump and filter, so in a submerged environement, with a lot of bacteria, still no degradation to be seen. However, PLA in a car melts quickly, as the temperature rises near the glass transition temp of PLA. In open air, it's not a problem at all (by the way, my anemometer and the part survived multiple huricanes... not all were full force, but at least one was very close to my position (in the caribbean), and it was cat4 or cat5 when it passed by...
Annealed overture nylon is my favorite material for high temp and strength. Higher tensile strength and impact strength than polycarbonate, temperature resistant to up to 180c, prints at only 260c without a chamber or even a heated bed, AND its only 30 bucks a kilogram and prints like a dream. Print it and anneal it like you would polymakers copa, do not try to print it like normal nylon or you'll almost certainly have a bad day lol. Not a fan of overtures other materials, I really dislike their petg compared to cheaper brands, but I gotta admit, they nailed it with overture nylon. Please be responsible and do not print it without an all metal hot end. Capricorn tubes are unsafe at 260c even though they don't fully melt. You can check their website to confirm this. Idk why everyone thinks capricorn tubes are an alternative to an all metal hot end. They probably are the best ptfe tubes, I do like them, but they still degrade at unacceptable levels past 250c.
Sorry but if you already know the tensile strength, well, you know which is the strongest. It would have been nice to hear an explanation as to why PLA and nylon, having the same tensile strength, break at different weights. Lastly, ABS turns brittle in the sun. Only ASA is resistant to UV.
Most printers now use an e3d all metal hotend or something similar. A genuine one is $40 and can print at a little over 300C with no problems. Cheap chinese knockoffs can have problems at temperatures that high, which is almost always caused by a crappy heatbreak and heater/temp sensor. These can be fixed with the best parts on the market for $30 or so, or $10 if you get a less-shitty knock off from Amazon. Those chinese knockoffs are supposed to print at polycarbonate temperatures, they just can because they are poorly built and those companies know most people who want to print at higher temps will be upgrading anyways.
@@lobsterbark ok hi, this is an old comment, but if i have a budget of around $1000 give or take would you be able to make a suggestion to start with good quality for a desktop printer... You are the first guy to speak with a bit of confidence on the matter - in a non sponsored way :)
@@ceejayc6502 3d printers have changed a lot since then. I'd look at resin printers, see if they make sense for what you need. They are only a tad more expensive and produce much finder detail than fdm. They used to cost a lot more and weren't worth it, but now they are, especially for stuff like tabletop models.
This video was just suggested by the TH-cam algorithm. It needs an update, and you should put the year in the video title to get the algorithm to better detect your update. Also, your update needs to include both chopped and braided/"continuous" fibers (ideally: carbon, yeast-grown spider silk from the CA company "Bolt Threads," human hair, and high-tensile steel filament). If you also added a metal sintering (SLS) and UV-resin-dual-laser-cross-linking tech like CLIP / HARP, you could guarantee high rankings and increased sales. (However, do slow placement of weights this time, and don't waste people's time. i.e. have them one after another, and post the "timestamps space brief phrase description" under the video so it is autosensed and put into the video's control bar. Such videos place higher in TH-cam's algorithm, and automatically yield a higher ranking.)
would like some help here i need to reproduce a intermittent sprocket for a 35mm/70mm projector .the sprockets aren't available anymore any suggestions?from what i can see they were made from a titanium metal but are very light.
Why did you make a hook when you could make a circle, or other pattern which would probably hold twice as much weight as you showed on each filament???? Just wondering?
Hi, I’m currently working in Nigeria and we need to manufacture small parts for the industries in Nigeria. Normally we would make brackets out of metal and have it galvanized, but takes way too long and most of the times it is a once-off type solution. To 3D print it makes more sense, but most of the parts and brackets is used outdoors. I’ve been tasked to find a solution. My question is, which filament will work the best. We do have the following average conditions in Nigeria: • Temperatures ranging from 10 degrees C (50 Fahrenheit) to 55 degrees C (131 Fahrenheit) • Humidity of 20% to 100% • Northern region is desert and southern region is tropical. • UV index from 6 to 12+ My thinking is that we need to revers engineer this solution, by first establishing the correct filament and then find a printer which will be up for the task. Could you please assist with the above.
Can you make a container to boil and freeze water and also safe to drink the water afterwards.. also can it be clear. Doing something unique with water for special properties
Would you consider printing a nylon hook and letting it sit in a garage for a couple of months, and see how it handles the lift? All my Nylon prints are super strong the moment it comes out of the printer, but after a few months, every print has absorbed moisture and gone limp. They are all flexible and I can no longer us it as a functional part. Please let me know if you exhibit the same behavior.
What was the infill on the PC hook? Also, what about impact strength? The slow increase in pressure is one measure of strength, but sudden impact is usually more destructive- how does the PC hold up to that in relation to the slow pressure measurement?
i wanna find that strogest filament that can feed 3d pen . do bodywork purpose like laptop, pc .. so i need strogest and heat proff filament .. any suggestion ?
How does the polycarbonate compare to polyoxymethyene (AKA POM). I've seen POM filament for sale and injection moulded POM is strong enough to make plastic gears capable of handling thousands of watts (though usually those are cut by machine from injection moulded blanks). I've seen RC helicopters with 10,000 watt brushless electric motors that have a POM reduction gear for example.
K i would like to point out that who ever was using the forklift was very unsteady and that could have added to some of the failures because to be honest the jerking or bouncing can actually exert ten times more pounds of pressure just like doing it if you stand on a scale and just from doing squats on the scale your body can make the scale go from say two hundred pounds to 1000 pounds just from the inertia of your body going up and down and hence the actual break point could have been much higher than measured due to the unpredictable jerking or bouncing motion of an quicker bump of the hydraulics did you factor in these inconsistencies because the one abs broke during a bounce and then quick bump of the lever which could have actually went much higher in actual recorded weight in essence
Ze advert for wolf bite. Or maybe polycarbonate. Also, abs degrades in UV light as well. So it is NOT a stable material. Also wrong print bed temp for ABS.
Why not use industry standard tensile test coupons? Then you can get actual 0.2% yield, ultimate strength, Chappy impact, and notch sensitivity that can be compared with properly spec'd materials. Your results cannot be used to design a load carrying part which needs those specs.
Hi, so which is the best to make helmet accessories to stick em to helmet surface? I need it doing well in sun heat for daily riding. Kinda custom patch for helmet what i was thinking. Is pc the best?
What is the dimension of the cross section in the hook? , if is possible. Because if the geometry change the results can change, so maybe we need to get the tensile stress before in order to create something according what we need?, nice test.
lol when you threw the part on the floor and claimed you cant do that with other materials LOL i doubt anything would break - maybe abs might show a dint- but the rest would be fine. great video- loved the poly carbonate strength
no information about various 3D print aspects, extrusion height, width, are not mentioned and the printing of the parts themselves are not shown... I have doubts of the integrity of the tests.
All right I'm looking at the video because I have a question to answer would it would ABS be good for like beyblades and stuff like they hit each other over and over over again really high speeds if you don't know what I mean just search it up I want to know if it is strong enough and it won't take too much wear and tear like it won't break within a day because I use these a lot
Man some people on Quora are so dumb. Just had a guy tell me I can't print wind turbine blades because they "won't be strong enough" then I see this video and they are lifting this huge tire with that little part LMAO.
Paul, thanks for the question. We've been printing with polycarbonate since March of 2014 with the HDx. What we've found over the years is that parts printed at lower temps (270C or so) tend to break easier because the layer-layer adhesion is weaker than at 290-300C. This will vary with printer type and also depend on whether or not an enclosure is (preferably) utilized. Not sure about pc max, but we can tell you that our filament is made from 100% polycarbonate pellets with no additives.
I wonder if polycarbonate is strong then high end Filament, like ULTEM,PEEK , PEKK AND PPSU. Because you said that polycarbonate is the KING of 3d 🖨 Filament.
I have a feeling that the pc hook wasn’t pc. It sounded wrong when it hit the floor. EDIT: I have pc and it sounds like ceramic Edit 2: That pc actually sounds quite rigid, and I’m pretty sure all of them would bounce back. That pc doesn’t sound very tough, and in my experience with pc like that (eg polylite pc) it’s extremely brittle.
This test is rigged by the rigging and lifting methods that your forklift driver is doing... PLA he jogged the lever to bounce the strap. On other high end filaments your lift transition was smooth.

I also used PLA for at least 2 years in an aquarium, as fittings for a pump and filter, so in a submerged environement, with a lot of bacteria, still no degradation to be seen.
However, PLA in a car melts quickly, as the temperature rises near the glass transition temp of PLA. In open air, it's not a problem at all (by the way, my anemometer and the part survived multiple huricanes... not all were full force, but at least one was very close to my position (in the caribbean), and it was cat4 or cat5 when it passed by...
Commercial video I couldn’t vacate less about
The main take-away I got from this video is that the first thing I should do with my 3D printer is to print spare parts for my printer. Lol
Annealed overture nylon is my favorite material for high temp and strength. Higher tensile strength and impact strength than polycarbonate, temperature resistant to up to 180c, prints at only 260c without a chamber or even a heated bed, AND its only 30 bucks a kilogram and prints like a dream. Print it and anneal it like you would polymakers copa, do not try to print it like normal nylon or you'll almost certainly have a bad day lol. Not a fan of overtures other materials, I really dislike their petg compared to cheaper brands, but I gotta admit, they nailed it with overture nylon. Please be responsible and do not print it without an all metal hot end. Capricorn tubes are unsafe at 260c even though they don't fully melt. You can check their website to confirm this. Idk why everyone thinks capricorn tubes are an alternative to an all metal hot end. They probably are the best ptfe tubes, I do like them, but they still degrade at unacceptable levels past 250c.
Sorry but if you already know the tensile strength, well, you know which is the strongest. It would have been nice to hear an explanation as to why PLA and nylon, having the same tensile strength, break at different weights. Lastly, ABS turns brittle in the sun. Only ASA is resistant to UV.
my concern is that most home 3d printers will not approach the temps needed.. so this may be a specialty filament for some time to come
Most printers now use an e3d all metal hotend or something similar. A genuine one is $40 and can print at a little over 300C with no problems. Cheap chinese knockoffs can have problems at temperatures that high, which is almost always caused by a crappy heatbreak and heater/temp sensor. These can be fixed with the best parts on the market for $30 or so, or $10 if you get a less-shitty knock off from Amazon.
Those chinese knockoffs are supposed to print at polycarbonate temperatures, they just can because they are poorly built and those companies know most people who want to print at higher temps will be upgrading anyways.
@@lobsterbark ok hi, this is an old comment, but if i have a budget of around $1000 give or take would you be able to make a suggestion to start with good quality for a desktop printer... You are the first guy to speak with a bit of confidence on the matter - in a non sponsored way :)
@@ceejayc6502 3d printers have changed a lot since then. I'd look at resin printers, see if they make sense for what you need. They are only a tad more expensive and produce much finder detail than fdm. They used to cost a lot more and weren't worth it, but now they are, especially for stuff like tabletop models.
what filament is best for making car parts for customizing
This video was just suggested by the TH-cam algorithm. It needs an update, and you should put the year in the video title to get the algorithm to better detect your update. Also, your update needs to include both chopped and braided/"continuous" fibers (ideally: carbon, yeast-grown spider silk from the CA company "Bolt Threads," human hair, and high-tensile steel filament). If you also added a metal sintering (SLS) and UV-resin-dual-laser-cross-linking tech like CLIP / HARP, you could guarantee high rankings and increased sales. (However, do slow placement of weights this time, and don't waste people's time. i.e. have them one after another, and post the "timestamps space brief phrase description" under the video so it is autosensed and put into the video's control bar. Such videos place higher in TH-cam's algorithm, and automatically yield a higher ranking.)
Should have used tilt back on the forklift. Would have been smoother to raise. Great video.
Thanks for the tip! Tilt back would have filmed better too.
What about carbon fiber?
would like some help here i need to reproduce a intermittent sprocket for a 35mm/70mm projector .the sprockets aren't available anymore any suggestions?from what i can see they were made from a titanium metal but are very light.
Infomercial...
Why did you make a hook when you could make a circle, or other pattern which would probably hold twice as much weight as you showed on each filament???? Just wondering?
Hi,
I’m currently working in Nigeria and we need to manufacture small parts for the industries in Nigeria. Normally we would make brackets out of metal and have it galvanized, but takes way too long and most of the times it is a once-off type solution. To 3D print it makes more sense, but most of the parts and brackets is used outdoors. I’ve been tasked to find a solution.
My question is, which filament will work the best. We do have the following average conditions in Nigeria:
• Temperatures ranging from 10 degrees C (50 Fahrenheit) to 55 degrees C (131 Fahrenheit)
• Humidity of 20% to 100%
• Northern region is desert and southern region is tropical.
• UV index from 6 to 12+
My thinking is that we need to revers engineer this solution, by first establishing the correct filament and then find a printer which will be up for the task. Could you please assist with the above.
Did you verify the volume of material used for each hook was identical?
Step 1. Fire your video team. Step 2, Stop reading cue cards. It's awkward and very robotic. Step 3, DROP THE MUSIC!
I'm dissapointed.
Not enough tests Imo... I'd like to have more specs too, how heavy are the hooks and durable as well.
Can you make a container to boil and freeze water and also safe to drink the water afterwards.. also can it be clear. Doing something unique with water for special properties
Would you consider printing a nylon hook and letting it sit in a garage for a couple of months, and see how it handles the lift? All my Nylon prints are super strong the moment it comes out of the printer, but after a few months, every print has absorbed moisture and gone limp. They are all flexible and I can no longer us it as a functional part. Please let me know if you exhibit the same behavior.
make a socket and use a wrench . wanna see if it snaps or just rounds the hole
What was the infill on the PC hook? Also, what about impact strength? The slow increase in pressure is one measure of strength, but sudden impact is usually more destructive- how does the PC hold up to that in relation to the slow pressure measurement?
Is Polycarbonate filament UV resistant and suitable for saltwater environments?
What would the best material be if you were to make a recurve bow?
is it possible to print nylon on ender 3?
PETG: am I a joke to you?
Carbon fiber reinforce filament: am I a joke to you?
i wanna find that strogest filament that can feed 3d pen . do bodywork purpose like laptop, pc .. so i need strogest and heat proff filament .. any suggestion ?
What about the metal composite filaments???
I was waiting for Billy Mays to jump on set.
How much infill was used on these parts
How does the polycarbonate compare to polyoxymethyene (AKA POM). I've seen POM filament for sale and injection moulded POM is strong enough to make plastic gears capable of handling thousands of watts (though usually those are cut by machine from injection moulded blanks). I've seen RC helicopters with 10,000 watt brushless electric motors that have a POM reduction gear for example.
from my experience POM is weaker but i dont have numbers for you.
another alternative to POM is Polyamid , i dont know if they offer this as filament.
K i would like to point out that who ever was using the forklift was very unsteady and that could have added to some of the failures because to be honest the jerking or bouncing can actually exert ten times more pounds of pressure just like doing it if you stand on a scale and just from doing squats on the scale your body can make the scale go from say two hundred pounds to 1000 pounds just from the inertia of your body going up and down and hence the actual break point could have been much higher than measured due to the unpredictable jerking or bouncing motion of an quicker bump of the hydraulics did you factor in these inconsistencies because the one abs broke during a bounce and then quick bump of the lever which could have actually went much higher in actual recorded weight in essence
Ze advert for wolf bite. Or maybe polycarbonate. Also, abs degrades in UV light as well. So it is NOT a stable material. Also wrong print bed temp for ABS.
What about carbon fiber nylon
What would be a good filament for Suspension parts for a Gocart or atv. I’m just starting out in 3d printing Thank you. I have a ender 3 v2
Am i the only one gunna call the forklift operator out?? Hes about as smooth as a motox track lot of good info on other stuff thank yall
Why not use industry standard tensile test coupons? Then you can get actual 0.2% yield, ultimate strength, Chappy impact, and notch sensitivity that can be compared with properly spec'd materials. Your results cannot be used to design a load carrying part which needs those specs.
The side with the "WOLF BITE" broke apart first?
For the love of god, please stop cutting to a different camera angle whilst the host is speaking toward the camera!
Great hook design for this test! ;)
Also I love that wolf at the end
Hi, so which is the best to make helmet accessories to stick em to helmet surface? I need it doing well in sun heat for daily riding. Kinda custom patch for helmet what i was thinking. Is pc the best?
So basically, if I wanted to print an AR-15 LOWER, I should use polycarbonate. Thank you for the advice.
What material is the cheapest ?
What is the dimension of the cross section in the hook? , if is possible. Because if the geometry change the results can change, so maybe we need to get the tensile stress before in order to create something according what we need?, nice test.
Holy moly man. You have GOT TO TURN OFF THAT BACKGROUND MUSIC PLEEEEAAASSSRRR MAN.
lol when you threw the part on the floor and claimed you cant do that with other materials LOL i doubt anything would break - maybe abs might show a dint- but the rest would be fine. great video- loved the poly carbonate strength
no information about various 3D print aspects, extrusion height, width, are not mentioned and the printing of the parts themselves are not shown... I have doubts of the integrity of the tests.
I want to print 1ton durablity part for brick lifting,,,help me plz!!!
I want to make hanger things... to hang
Fork lane arm part and bricks
Oh, so the one who holds the most weight is the strongest one? Hmm, why did i not think of that?
Erick, THANK YOU! This is such a well done explanation, I'm going to incorporate this into my lesson plans with my students. Thanks again!!
Stephanie Perample Butler please don't...
How about carbon fiber filaments?
How Long have you been printing, was it 2015?
Seriously… I think I have new trigger words now
I'd love too see same type of video.but the Hook being closed .pretty much n 8 .n see how much weight they can take
All right I'm looking at the video because I have a question to answer would it would ABS be good for like beyblades and stuff like they hit each other over and over over again really high speeds if you don't know what I mean just search it up I want to know if it is strong enough and it won't take too much wear and tear like it won't break within a day because I use these a lot
Including all the other fillaments
You tried pulling it across the print, pla will break quicker in impact and bending
Man some people on Quora are so dumb. Just had a guy tell me I can't print wind turbine blades because they "won't be strong enough" then I see this video and they are lifting this huge tire with that little part LMAO.
Is Asa an option to?
I feel a better hook with more curves to equalize the stresses could be made, and also, does this remind anyone of Cnc kitchen vids?
Best explanation ever!
can i have the STL file of the hook?
I shit myself when the polycarbonate broke. Scared the life outta me. I think you should have used a strenght test gauge instead.
I wonder if the Pla could've gone higher if the tire wasn't bouncing.
For anyone here, leave. I suggested 3D Printing nerd. Hes not sponsored and doesn't show any favorites to one company or another for performance.
I've been using polymaker pc max. Your polycarbonate prints much hotter. What are the differences?
Paul Robertson I've been wondering the same thing
Paul, thanks for the question. We've been printing with polycarbonate since March of 2014 with the HDx. What we've found over the years is that parts printed at lower temps (270C or so) tend to break easier because the layer-layer adhesion is weaker than at 290-300C. This will vary with printer type and also depend on whether or not an enclosure is (preferably) utilized. Not sure about pc max, but we can tell you that our filament is made from 100% polycarbonate pellets with no additives.
What filament is best for high speed (3000 rpm, as a base) gears??
Under high load and or torque
IGUR 1150
What’s the best material for best layer adhesion strength as sometimes you can’t print parts in a certain orientation.
Why are they not a little more gentle with the forklift?
What about polypropylene or PP you don't handle it
How heavy is ea. hook total weight ?
An interesting test would be of impact resistance...
Also where is PETG in the test?
I wonder if polycarbonate is strong then high end Filament, like ULTEM,PEEK , PEKK AND PPSU. Because you said that polycarbonate is the KING of 3d 🖨 Filament.
PLA is NOT considered to be biodegradable (unless very specific conditions are met), therefore not compostable. It IS degradable though.
Where does PETG fit
And with base model printers starting at $3,000 I'm sure they do a fantastic job 🤔
I have a feeling that the pc hook wasn’t pc. It sounded wrong when it hit the floor.
EDIT: I have pc and it sounds like ceramic
Edit 2: That pc actually sounds quite rigid, and I’m pretty sure all of them would bounce back. That pc doesn’t sound very tough, and in my experience with pc like that (eg polylite pc) it’s extremely brittle.
The load shocking though lol
This test is rigged by the rigging and lifting methods that your forklift driver is doing... PLA he jogged the lever to bounce the strap. On other high end filaments your lift transition was smooth.
