- Last episode we built a heated bed for just $5.00, so today we're insulating it for even cheaper using common household materials anyone might have laying around, like packaging foam and cardboard!
Insulating the heated bed on your 3D printer is a great thing to do since it saves money using the printer in the long run, and protects the environment by reducing carbon footprint and waste heat emitted into the atmosphere. With this simple insulation that literally only costs pennies to make there is no downside to adding an insulation to your printbed anymore!
I was able to increase the maximum temperature of my weakish bed heater by about 10 degrees, as well as shorten heat-up times to a resonable 3 minutes 30 seconds for 60° C.

In case anyone wonders why I didn't use the inbuilt thermistor to measure temperature, it's because I didn't feel like finding the right code and programming an Arduino just for the video... Given my level of expertise in programming that would've been a multi-day effort.
Also, this video was initially only supposed to be a 5 minute segment of a longer video called "Making the electronics" but before I knew it my timeline had blown up to 10 minutes so I re-shot the intro and decided to turn it into a standalone video! 😅
lol
I absolutely love this series, this is truly what reprap was made from. Keep at it, I need to see this printer print a benchy.
You shouldn’t be disappointed that you aren’t reaching 120 degrees. Almost nobody ever uses those bed temps. I print ABS/ASA a lot and I never go beyond 100 degrees. Amazing job!
Thanks! Yeah I'm starting to realize even some off-the-shelf printers don't go that high. But tbh I was more disappointed by not reaching my goal than because I really want or even need 120 degrees 😅
i love your energy, lately youtube has been reccommending me some amazing new channels
Yea they recently changed something about the algorithm, many people (me included) also find a lot of completely unrelated recommendations on their home page, glad it turned out positive for you
Always happy to see you upload!
Man, this series is so awesome. I really like your approach to all these topics. Keep up the great work!
Glad you enjoy it!
it was so nice watching the videos and it is a very good improvement in your project and you did not give up on it❤ so nice
Very nice improvements.
Believe it or not , my neighbor just gave me a big roll of that space-age foil like what you have.
It looks like 1/3- 1/2 of your roll has been used up.
I think it's the same type of material they make lithium-ion pouches out of.
I checked the material out with my digital multimeter & this stuff seems to be non conductive
P.S. my neighbor said he had the role given to him by his new neighbor. He then gave it to me. Apparently his neighbor used to work at a place that made materials for Space Rockets👍
Cool! The stuff I have is conductive on the shiny side tho, so I guess the foil lipo cells are made with must have another layer of plastic over the metallization.
Someone suggested it might be mylar.
But yeah, it was from something scientific, he explained the vapor deposition but I can't remember what it was supposedly used for.
Wow you're definitely getting the value from that spray adhesive
I know right, lol
I think the unknown foil you used is mylar, you can get them as emergency survival blankets.
Also if you counter-bore the holes wider you could still use the same washers down inside. Then the springs can't bind on the sides or slip down, bonus that it would hold the washers in pockets to be mildly less finicky.
Aah that might be.
I'm gonna do that eventually with some slightly smaller OD washers, but only when I take the carriage off anyway, then I can use the drill press...
once you can print parts properly, maybe consider printing and implementing something like the Voron Unklicky Probe for automatic bed mesh levelling, which would allow you to mount the Bed with metal or wood spacers, making it a lot more sturdy
NICE!!!
I attached packging fom that came with something i ordred from China (presumably some kind of PE foam, feels like it) to my printer heatbed for an experiment back in the day, because i wasn't entirely happy with the temperatures i would achieve. Good thing i was careful to monitor it. At first it seemed perfectly fine, but after a while it started sort of seemingly sublimating or gently smoking up the room. It was really very faint, you had to look closely, and there wasn't much smell either, but a lot of the foam was just gone. So that's a material i will never use hot again. When that happened, the bed thermistor reading barely exceeded 100°C.
I also had a fire extinguisher at hand but ended up not needing it.
Cardboard should be perfectly fine, and i have gotten a spectacularly cheap piece of cork which hadn't caused me any issues.
I no longer use bed springs, i have an easily adjustable hard mount. Yes, this is how i broke my glass. I thought my touch probe (servo swinging a mouse button switch) was reasonaly free of mechanical bugs, well it was not.
Good to know, yeah the translucent-ish foam from China is usually PE foam, Aliexpress packages is where I got mine from XD
Given the melting point it makes sense it started to degrade, were you running it on the bed directly or with a layer of something else in between?
Cork is definitely the safest way to go, tho on my next version I think I'll replace all those layers of flooring stuff and PE foam with a single quarter to half inch sheet of polystyrene, at least that should stay together.
Haha for the time being I'm glad to have bed springs that are somewhat on the soft side, it'll provide a buffer zone for when I inevitably end up ramming the nozzle into it!
@@ChronicMechatronic I had it slapped on with a bit of kapton along the edge directly under the bed. I understand it's a lot safer in your build where you have some buffer material in between.
I'm really not fond of springs. But I mean first your printer has to print. Mine has been printing for a long time, it just needed to print prettier, and without springs it absolutely does.
"we are going to use asbestos for the isolation cuz the price"
*takes a crowbar and starts hitting the wall
Lmao 😂
I took a poke around and looked to a few photos.
Your wood work is very good looking in the Photos.
I also noticed your Website link is Broken
Yeah, those stock photos taught me a lot about photography and photo editing, but now it's basically abandoned :(
I had to delete my website for... reasons. One of them being that I never seemed to have the time to keep updating it, there were only projects from my high school time on it and that's quite a while ago now... I thought I had removed all the links, where did I miss one?
I have a question, what is the name of the bpue foam u used, and is there any other choice of replacement?
I don't know what it's called but it was just a different kind of styrofoam. Just replace all layers of foam with a sheet of styrofoam of whatever thickness works for you and you should be good to go. 👍
It's what I'm gonna do next time, too.
Ok thx, me and my friends are working on a 3d printer, I'm from India and we r trying to make the it under 6000 rupees. So ur tutorial is really helpful and interesting. I never thought making our own stuff would be a choice. But u proved me wrong.
Also we r thinking of 3d printing the linear bearing to go on the smooth rods. 3d printed from a store. Will that be OK?
@@restingsox9022 sure, I would print the ID slightly undersized and then carefully drill it out or enlarge it otherwise until it slides on the rod smoothly. You can get great smooth rods from discarded inkjet printers (except Epson ones cuz they cheaped out too much) HP still seems to have them tho 👍
@@ChronicMechatronic Thx!! U r one of my fav utubers. Anyway one more question lol , i didnt quite understand the math u did u find how many rows of aluminum strips u would need. so can u send like the equation or smthin.
Where did you get the bed?
What a question, made it of course ;)

If you place a sheet of paper on the table when you heat up, you will notice a significant difference
Really?
@@ChronicMechatronicyou should, your IR sensor should never have been able to reach or read more then the maxium your table can actually reach, as thats just how the second law of thermodynamics works. Same effect as the never reaching hotter temps then 5800k from sunlight.
Convection was just cooling your table, absent that your sensor and directly below it was getting heated beyond the equalibrium in plain air.
@@ChronicMechatronic It will heat up faster
@@AnonymousAnarchist2 interesting I need to look I to this, I thought the IR sensor heating up just shifted the measurements upward...
@@marcosevangelista3558 oh you mean because of a slight insulating effect by the paper
Isn't spray adhesive flammable?
Primarily the butane used as propellant in the spray can. The solvent in the glue itself is probably somewhat flammable but as soon as the glue is dry there's nothing left :)
Hi Ben! Great post. btw you have nice neighbors... Wish they'd subscribed to your channel ;) There's no detail that doesn't deserve an explanation in your extreme analytic approach, likely the first trait of real engineer ;) I'm glad that more and more people discover your channel. Have you cracked youtube algorithms' secrets?😆
Hi Phil! That specific neighbor didn't even know about my channel until this year, he used to give me tons of interesting and useful stuff to take apart back in the day, but fice years ago he kinda developed a grudge against my mom so everything went no contact for years... Now he's talking with us "kids" again. The other neighbor and her daughter are subscribed as far as I know :)
You're right, going down rabbit holes is my favorite past time it seems, and the thing that for me makes 95 percent of youtube not worth watching, is because everything interesting always gets glossed over 😂 I've really gotten into watching machining content over the past year since it turns out the excessive perfectionism and excruciating attention to detail is totally up my alley. And you can imagine my relief when I saw that part of my audience also watches one of those machining channels, as it means I'm finally on track to get the right audience for my content!
As for the algorithm, I would think I've been pretty much on it for a while, tho I'm still getting nowhere near the growth I'd expect to be normal with as hardcore of a strategy as I'm pursuing, so I probably am not. And if it's just that I'm not able to upload frequently enough.
One thing that always annoys me is like this brand new channel called "Not An Engineer" that popped up in my recommend, first video - bang, 254k views or something, 50K subs.
I'm like: his video wasn't any better than mine are, why don't I get 250k views? 🤷
But whatever, I guess we're supposed to be happy with what we have.
6.9K coming up soon, lol. And the amount of money a channel makes is arguably more important than the subcount, I'll be signing a new contract soon and I got a raise 🥳
@@ChronicMechatronic I went on deepl (an awesome AI-based German translator) to have more precision about "excruciating attention" and it gave a fair translation IMHO "une attention extrême". You help me improve my so wanting English. Thanks.
Second relevant point: TH-cam algorithm. I agree with you about "Not An Engineer". I must admit that the channel title is great. People are afraid of academics and prefer to deal with reviewers they assume are socially close to them (I love uneducated people, as demagogic Trump says). Picking the right motto is part of the game:"Degrees are expensive, just make stuff" as the guy seriously explained in his very first post. Definitely a rejection of the traditional way of learning i.e. having someone, maybe a master to teach you the basis. The dumb claims that his highness does not need that, your learn by doing. So narrow-minded approach of education. What he says applies only in very restricted areas e.g. typically manual (without any kind of prejudice though) hobbies. You can't imagine alternative solutions for common issues if you don't have some serious background. That's your case Ben! especially in that heat bed design.
But the guy's approach is beyond demagogic. I can't really blame him, he knows what he does and he may be an engineer though... I'm a fan of Russian engineers on youtube. Most of them have given up on posting videos. TH-cam has stopped paying them since the beginning of Ukraine war... but continues to use those videos as normal ads baits. IMMORAL! Let me recommend you just 2 channels that may interest you. What they do requires a solid knowledge of the matter, respectively in mechanics/energy fields and physics: @pevcev and @igorNegoda. They're not in a niche of niches though. But youtube marketing is smart enough to spot potential sources of popularity. Quality is not the premium criteria I suppose. We have to deal with it.
Arabs say:"Neighbors are as important as family: they can poison your life when they're bad". Have a bright and inspiring weekend Ben!
Btw remember when your very first post earned 35K ;)
As French proverb states:"On n'attrape pas les mouches avec du vinaigre".
@@joetkeshub hi Philibert, I should probably be writing in French as mine's more lacking than your English, but it takes so much longer 🥲.
The "not an engineer effect" as I'll call it also works on me by the way, show me some complicated looking formula with lots of constants and greek symbols and my brain will automatically shut down, but explain the same formula to me in layman's terms with simple numbers and units I'm familiar with replacing the variables, and I won't have a problem typing it into a calculator. It's why in my "designing the heated bed" video I showed off the calculations without ever mentioning ohms law. Makes things suddenly look so simple.
I agree that "not an engineer" knows what he's doing, he clearly took a page out of Stuff Made Here's book, probably appealing to a similar albeit possibly slightly less educated demographic. I wonder if this marketing and business knowledge somehow comes built into people these days and I'm the only one who finds that way of thinking extremely unnatural.
I'll check out the channels you suggested.
Yeah, disagreeing neighbors can mean trouble big time...
Have a nice weekend as well Phil!
@@ChronicMechatronic "natural" sounds like "normal" i.e. extremely subjective.🤔
not sure having all those layers would help more than just a thick layer of cotton you could get from a old hoodie
Between only cotton and cotton+foam yes, I as far as I know materials with closed air bubbles retain heat better because air can't travel through them. Though for all intents and purposes a stack of cotton would work well enough too. I just think cotton+foam gives a better result overall.
hello from Ukraine))
oh yeah
Silicone baking mat !
An important part of your post is about the risks your design may induce th-cam.com/video/1PF-9yvzd4g/w-d-xo.html it's like a legal warning ;)
Its pretty much meant to be one, those easy to use solutions may seem like a simple life hack despite entailing serious dangers under the wrong circumstances. And if the wrong person were to treat it like one without being aware of those consequences I don't want to be at the receiving end of a lawsuit 😉
Everyone is still responsible for their own actions and common sense, even with "cool" youtube videos showing what CAN be done.
You might notice in the description of the thermal engraver I built for my pen plotter there's a long disclaimer as well. Actually I should copy that one over to this video too.
