Want to get your 3D prints to the next level? Check out our Heat Set Inserts and Tools at cnckitchen.store (Free shipping worldwide starting at €100). *QUESTION:* What would you use hot melt glue filament for?
why dont you find lower melting point TPU for the sticky side , and then use TPC on the top which melts in slightly highertenps , alterntively there are shoe glues that are flexible after cure, but they smell strong that you can paint on the other side. or maybe press the hot glue into a thin sheets , then cut to size with a plotter maybe ?
Is it possible to mix pla and gluestick you just need to figure out the mixture percentage
I actually don't have a hot glue gun.
@@kira07😊😊😊😊
You can use pla flax instead of glow, it could work very similar and much more easier to print
Finally, a 3d printer that is just a hot glue gun. We've ascended.
😅yeah just wanted to say that because literally everytime when someone doesnt know 3d printers the only way they understand usually is the hot gun xD
We’ve ascended so much that we’ve gone back to square one
@@3DWolfEngineering The real trouble is explaining resin printers 😂 "So yeah. It's upside down and there's this UV sensitive liquid and then..." 😅
@@The_1ntern3t hahaha yeah youre so right 🤣lol... luckely havent had this situation very often because i dont yet have a resin printer😥 dont have a space for the toxic stuff yet but i miss every day i cant create cool detailed stuff like figures, tempplates... Id propably explain it with very thin drawings you stack ontop of eachother ?
Everything old becomes new eventually.
"I didn't only make it for the giggles." Sounds like giggle addict talk to me.
😂 the video was fun. Just brush some hot glue at the backside of the patch to achieve the same result. 😊
@@chipcode5538I feel one is cleaned than the brush on option.
During the intervention. "Your so obsessed with your giggle that you neglected ME. WE used to giggle TOGETHER. 🥺😭"
Hi Stephen, maybe you might have better luck with higher temp rated hot melt glues. The glues I use at work have a more yellow hue to them versus the crystal clear ones you're using. They melt at a higher temperature but solidify significantly faster. They might be harder as well. We even buy it pelletized as well as in large diameter sticks. You should have no problem finding pelletized hot melt if you ask around industrial suppliers, it's very commonly used.
for this application i think you need the different melting point for the bottom layer (~150) and top layer ~(200) - otherwise you would melt the patch and get rid of detail
@@gedr7664 he could iron from the INSIDE of the shirt , so the thing that melts first would be the glue . It will be significantly harder to place the stamp perfect but it would fix the problem .
@@gedr7664 maybe if ironed from the inside it would work
My mom has some white glue sticks and she says those high temp ones will burn the absolute hell out of you if it gets on you. Should work really well on fabric though.
Was going to suggest this. Glue sticks have varying cure times and chemical compositions. For fabrics it would also help a lot to have something that didn't soften in the sun 😅
The only thing I'd change about this process is ironing the patches from the fabric side, so more of the heat goes to fabric then hot melt glue THEN tpu, rather than hitting the TPU first. In my experience (with normal patches!) this helps them adhere better because the fabric is heated up to match the glue.
This!
This!!!!
I scrolled to the comments to point that out too XD
Oh hey thanks I actually didn't know that about iron on patches. My jeans always rip at the crotch so I'm always using iron on patches (tacky I know but I love these jeans). The corners of the patches always peel. Didn't think about heating the fabric up as well.
Hope he sees this
This is amazing! I had no idea filaments used to be oiled, totally makes sense though - great work!
@BPSspace @CNCKitchen collab I never expected.
But can you print gluesticks with it?
@EightOneGulf You just gave me a shower thought.
You're asking one of the most important questions in the world right now. Answers are needed for this
With less infill for more glue sticks per glue stick 😂
Hahaha
I do service work at a factory that makes glue sticks, they use a horizontal screw extruder with a 1" nozzle where it gets melted then it gets pulled through a 50ft water bed by a puller belt on the other end. They are indeed coated in oil to prevent them from sticking to the puller belt when they are chopped down into individual sticks.
Water bath? Interesting
PCL in past was used as a hot melt glue and filament out of that is readily available.
Interesting, I have some still lying around. And the XL should be able to handle that and I already have a profile for it. So worth a try.
@@jonasniesner At those temps have to keep it away from any clothes dryer tho. "PCL filament is a type of 3D printing filament made from a biodegradable and bio-based polymer called polycaprolactone (PCL). PCL is a good choice for beginners and kids because of its low-temp and safety. It is also eco-friendly, food-safe, and non-toxic. PCL has a density of around 1.2 g/cm3 and has exceptional mechanical properties. It melts around 60°C making it a safe thermoplastic to print and has a glass transition temperature of -60°C making the product extremely flexible and tough."
So a few months ago Lost in Tech showcased a filament made from PCL (polycaprolone) which melts at low temperature and might very well bind other polymers to textile. PCL pellets are also very easily and readily available in small and medium quantities e.g. as a crafting material, mould making material, temporary tooth filling.
No need to make filament, PCL is already available for medical applications. Price is a bit higher but still acceptable.
Great idea! I think I even have some around here.
PCL pellets work really well to adhere pvc pipes together at odd angles that you can't get connectors for.
@@jonasniesner You can buy PCL filament.
@@CNCKitchen ich könnte dir EVA Granulat zusenden wahlweise in Weiß oder transparent/beige.
Maybe the answer is to make a new extruder that can accept the glue sticks directly :) Also maybe a smaller nozzle size could make part cooling easier?
I'd buy ^&% tons of EVA filament if it were commercially available. Making their own iron-on patches would be the hottest project ever for my middle-schoolers' 3D printing class.
Maybe you could try Avery 3279 ink jet fabric transfers. You create your pattern in your favorite drawing program, print it onto the 3279 paper, use an iron to apply it to a tee shirt or whatever.
Temu has thin sheets of hot melt glue dirt cheap specifically for fabrics if your logo/etc. would be regularly shaped and without voids to cut them out for hot pressing.
Always happy to see you thinking outside the box. As a practical note though, hot glue is available in a sheet form that maybe you could print on top of then trim off after printing.
Yeah, I was thinking why not just use the iron sheets for printing on. Work great for ironing on fabrics.
You could see the panic in the hand movements when you touched the glue lol
👋🤚🖐✊👎🙌👊👏👊🖖🖐👏👊👏
You could build a large extruder to feed the sticks directly into a long conical nozzle to get to normal filament size. Should be easier than chopping everything up :-)
The problem with that is that then we have to melt down the whole stick to temperature and then cool it down very fast so it can spool, the thermal mass is just too high right? Maybe that could be solved by using some sort of chiller just bellow the nozzle? Like placing a tiny radiator connected to a AC unit in front of a high speed delta fan
Maybe it would be easier and more consistent to design a hot end that can directly take full hot glue sticks, which would eliminate most of the problems you had. Taking the heating element of a hot glue gun and modifying it a bit might just do the trick.
Patch makers iron-on a double sided adhesive. Madeira has three different Heat Seal products using different materials: polyamide, polyester, and polyurethane.
This...the whole time I was thinking of Badge Magic like Scouts use. It's basically the same thing without all the work.
Temu has such dirt cheap.
Hybrid EVA-PLA strength testing!!!!
Yes please! The adherence of the layers is super interesting
Both are having distinct melting points
Dry ice is used by welders often, so even in a small city or town you should have a welding supply seller nearby who will be able to provide it to you.
plumbing too
Co2 fire extinguishers, where ever locally they are refilled as well.
It pains me that u didn't use a cheese grinder
An experiment that you learn from is never a waste of time. Really neat to see you using an OmniDrop extruder, They are great will work with any material. Max did a great job designing them.
TPU can be ironed onto cloth directly and there is no need for any adhesive. Place the tpu patch down first onto a wax paper, place the cloth over that and a final layer of wax paper then iron on the patch heating through the cloth. The only thing that really takes any practice is melting it with even pressure and not keeping the heat on for to long smearing the tpu out. The results can be great and hold up to many washes before a corner starts to peel off but its no big deal you just iron it again.
I see Temu has hot melt thin sheet material dirt cheap specifically for fabrics, wonder which would hold better, those, or your direct TPU... may have to try and compare!
I second this. I have had great success ironing TPU on cotton.
how many layers and at what layer height would you recommend?
For that matter, you can print TPU straight to fabric, too.
An interesting proof of concept, and for someone willing to put in the time probably quite practical and useful. One thing comes to mind, reversing the process, printing PLA onto baking paper stuck down on the build plate (would it stick - don't know), then printing the glue on top of that. The print could easily be lifted with the paper and is already ready for ironing onto the fabric.
If you manipulate the printing path I bet you could mimic the look and feel of an embroidered patch. That would make this incredibly useful as a potentially cost effective alternative to custom sewn patches.
You can actually embroider TPU directly really well, I make and sew on TPU patches all the time. 👍
The idea is great, but to fix problems with making filament: why not make a custom extruder that can work with 10mm hot sticks so that you will eliminate half of the problems.
Yeah for that was my first idea
One thing that comes across my mind as an issue would be the amount of material you're pushing into extruder with one stepper motor step. Wider cross-section of the raw material makes fine control over filament feed more difficult, as the nozzle diameter still remains ~.4mm
I guess the solution in that case would be adding a gearbox to fix the ratio between stepper motor and feeder gear, but then you'd have slower retraction speed, etc., etc. So while fixing the root issue, attempting to create a custom extruder would definitely bring some new problems into play :)
you can get pellets from the shaving aisle in stores, they are used as a waxing strip material.
I enjoy watching your process so much my friend. Your curiosity and no nonsense approach to problem solving is just incredible. Freezing the gluesticks, modeling temps after the glue gun, adding the oiler, there were so many brilliant little nuggets in this video and I just loved being along for the journey. 👏
I need this it compliments my TPU addiction perfectly! I feel like the odd guy out but TPU is by far my favorite thing to print with and design for, yes it has it's challenges but it has so many amazing use cases.
I almost exclusively print in TPU at home.
you can buy hot melt glue pellets in a lot variations for processes like industrial book production
And now try it in the other way around: 3D print some PLA sticks and feed them into the hot glue gun. Would it work?
Playing with hot glue was not a waste of time, as you (and we) learned a lot in the process! Thank you for sharing your experience!
Appreciate it!
3d printed patches have been one of my go-tos for a minute i tried iron on backing, but just sewing them on is what ended up working the best
I love how your troubleshooting kind of came full circle back to using filament oilers. It's funny how these issues probably were the same things that the 3d printing pioneers faced.
As StormBurnX said, iron from the fabric side rather than the patch side, that way the TPU doesn't warp as much.
I admire your absolute patience with this project.
This hits the sweetest spot for me - i just got into machine embroidery and i am totally going to be doing some 3dp appliques
What if you use a water bath before you try to spoil the glue? Have the filament come out of the machine into a water bath and then loop up into the part of the machine that wraps it around the spool.
I think this may be the right application for that underwater 3d printer...
Jetzt muss ich es mal kommentieren nach so vielen beeindruckenden Videos lately: Du bist a Matz! Kodus, Stefan
Thats a fascinating concept. Plus incredibly recyclable.
I thought I made up the idea of a filament oiler for use with scenting filaments.- but sounds like its a real thing. I love youtube for uniting inventors across the web. keep on building!
I use the hot glue gun reference when explaining 3d printing also 😂
I think that a thin sheet of hot glue would work better than a filament for the iron on patches. The sheet could be attached to the bed by heating and the tpu patch would be printed on top of the hot glue sheet
really great idea, and kudos for being so persistent to reach your goal, think that this filament have some future and would love to try using it myself to make some patches
Thank you so much for the inspiring videos! 😃 Sometimes when I'm tired and the world seems to do everything wrong, I watch some video of yours, because I can trust, that Stefan is meticulous, analytical, organized, and objective in his methods and the presentation and enthusiasm is flawless 😃👍
That's a cool idea. For the t-shirt you should try ironing the fabric with your logo underneath!
Could use the iron from the other side of the shirt, so that you aren't melting anything but the glue.
Those patches are awesome and it's so awesome to be wearing a 3d printer patch that, theoretically, you can make.at home!
Again, Stefan, your explorations and hard work impressed me. You have such good ideas. Thank you for this vidéo. ❤❤
I printed hot glue sticks with filament to repair a failed print>:
thats actually smart...and especially its propably better than a 3d pen
@@3DWolfEngineering I know most 3D pens aren't the best, but I have a Mynt3D Pro pen and it works really well and I haven't had any problems with it and I've had it for a few years now
You should have tried letting it run through a tub of ice water instead of the oiler.
I have no use for this right now but i very much like your way of thinking and creativity. Good work.
I have this idea for a long time and finally someone made it nice.
Later you can make repair videos where you dig the melted or twisted stuff out of the washing machine and dryer. All it will take is one time where the logo goes through a bit too hot a cycle and its all over. Also the hot glue stickiness may migrate into the machine even without physical debonding.
The melt point of low temp hot glue is over 120° C. I doubt most peoples washers and dryers are running over boiling temps
@@billallen6109 It doesnt need to "melt" to be a problem. It just needs to break down. A decent machine will have a heater inside it to bump temps up assuming its not a steam machine. My concern is putting an adhesive that doesnt set is just too much risk.
Just expel some hot glue onto the build-plate from the glue gun, then with a cold aluminium plate flatten it to the thickness you want. Maybe a roller would work. If it sticks to the plate it wasn’t cold enough or thick enough. Then print on that
very cool, love to see creativity in the technical space. Thanks for sharing.
Great engineer-thinking as usual. I love your attitude and persistence
this is fascinating! I always use a glue gun as and example of how printing works so seeing this is oddly full circle! Nice work!
The patches are such a great idea. I wish I could make my own with my printer.
I researched the hot glue topic last year but didn't found anything so gave up, good to see a video on it 👍
Awesome job! So much effort! Thank you 👍
You're so smart. This video was very informative and interesting!
So nice, keep up the work!
Crazy hack, crazy skills! Love it!
I’ve wondered if this was possible for years! Thanks for doing it
This is actually a great project, thanks!
Great video! We'll definitly create our own iron-on patches now.
I have an inkling that it would work really well to print your colors first, then the hot melt atop, giving you that nice surface finish of the bed
i see a few options some kind of fine powder covering the filament could solve the sticky issue, a stripe of plastic candy caned around it could help with both of its problems but the last 2 have the issue of needing something that can melt about the same temp and mix with it, and some kind of system to cool just the last lair like a slowly filling tank of cooled water can help solidify it.
Mixing the glue with regular filament also came to my mind.
wow its amazing how much work you put in this! Thank you for showing us the endless possibilitie of using a 3D printer. For me personally, if i were to make iron-on badges for tshirts, i would use adhesive vinyl and cut it with a plotter. That would spare the troubles of making the hotglue filament and probably money to buy the shredder.
What a fun idea!
Stephen is a creative and innovative driving force in the 3D printing community, always hitting us with the most amazing ideas!
Amazing proof of concept!
I thought it was very interesting. I can imagine printing pieces which can be assembled to form large objects, using hot glue printed edges, or attaching printed parts to other types of materials. Thank you for sharing.
We made something like this at work for masking circuit boards about a decade ago. We used a glue dispenser made for doing cardboard boxes on an assembly line.
Amazing work, as usual 👍
I just bought an Artme3d Mk2.5 extruder and a plastic shredder and now I really want to try this
You, Sir, are crazy in the best possible way.
Lovely idea! Better then just printing on iron-on-transfers.
Super cool! I would have never those oiling filament would have been a good idea... Learn something new everyday!
Definitely cool. It's nice to see something different in this space.
i would buy patches!!!! ive allready thought about it but im a novice in 3dprinting and havet got to TPU yet, but i have some custom patches done!! awesome work!
Experimenting and learning is never a waste of time!
Very creative! I am sure there is a future for 3D printed adhesive layers!
Brilliant idea. Thanks for sharing
I was just thinking of this subject earlier today. I don't plan on putting glue stick in my Artme3D when it arrives.
Another great video! I usedhot glue on my printer to rapidly fix 1 wall width support after a small layer shift. I quickly found out that hot glue was so hot, that it melted the PLA support wall, but somehow i managed to save the print. What I found out later, is that hot glue plus a print bed equals great adhesion. If I wasn't using hairspray for that print, the bed would be toast.
Thanks for all I suggest you put shredded plastic with the shredded hot glue sticks to be less flexible Or u can pass the output hot glue filament on cooled water with ice before u roll it❤
I asked myself often if this would work. So looks not so nice to do it at home 😅 but I'm happy that you did it
Great video! I'm glad that people like you exist, who are to afraid to experiment.
I rly like your way of thinking because i also tend to overcomplicate things. But: it seems to me the best way get this idea done is to work on a good way to just do that single bottom layer of hot glue by hand, like with a height adjusted spatula or something like that.
Bro ich klick auf das video und hab direkt das gefühl gehabt, dass du aus deutschland komms. Sber sehr cool, was du machst❤
A cold working tip: freeze the blender pitcher also for extending the time you can cut it and remove easily. It reminded me of my whip cream making days, it goes much better when you freeze the bowl and the whisk or mix blades. You could probably mix 15% parrafin in or a number of other things, the sticks could just be a binder in your spool maker.
I have done simple TPU shirts before and with long heat it was stuck for a long time by it self, handled washing and drying with 0 issues. Later I have tried and Even PLA works well with fabric.
Man, I don't even have a 3D printer. But I love how you approch problems and solve it. This is the kind of entertainment I need.
Great work mate!
I found the sentence „I had no clue“ particularly amazing, because it sounded like „I had no glue“
I did this with straight PLA a few months ago and at the right temperature, it fuses with the fabric. Can be a decent idea for some "armored" fabrics.
Finally a video that deals with recycling in a practical way. Cheers!
I was waiting for someone to do this
Great idea. Bravo!
