@@realgoose Good question. I'm currently redesigning the extruder with the insights I got from making this video and I'm pretty excited about it!

I wonder if with your original design you were getting too much back pressure from the compression of the glue sticks. It would be similar to printing with a soft plastic like TPU I'm sure.

This admits a super convenient path to recycling: mold the material to recycle in a cylinder, then let it cool and use the rod in your extruder. PLA scraps (Bambu poop) and shredded PET bottles are obvious candidates.
Hey quick tip for working with hot glue: Keep a bottle of rubbing alcohol/isopropyl alcohol/ethanol with you, just a few drops at the seam will make any hot glue peel off any surface in seconds!

Chocolate printer anybody?? The man just made automatic reloading cartridges. I know it wasn't talked about much in the video, but this is definitely the biggest thing in the video and a genuine innovation!
@MumrikDK they are, but the one commercial cartridge one has to be reloaded and remelted, which takes like 20 minutes if I remember right (not less than 15). Smaller cartridges would have more control over the melt and pressure. There was one run by a gear pump that was fed by a chocolate bowl, but they seem to be gone now. If someone used this to feed cartridges and a giant silicone sock over the whole thing, they'd have a sweet chocolate setup. That and two heaters.
Nothing convey frustration better than swearing in Dutch 😂 I admire your perseverance, hats off to you, youre an inspiration to all us others who f* around and find out! 👍👍👍
@@properprinting I didn't even think of the auto-feeding system when making this comment, but indeed that would make a lot of sense. Kinda considering doing this project on my printer which I just rebuilt the rods for lol
This. Is. Perfekt! Every time someone asks me how a 3D-Printer works I tell them to imagine putting down Layer after Layer of a conture with a hot glue gun. And you just build that metaphor! I'll use your video for years to come, thanks a lot!!
I go through phases, and I get excited to print then I get fed up and do other things. Thank you for igniting the passion again. I want to print weed trimmer filament for super strong parts to add to the yard tools.
This is wonderfully cathartic. I don't know how many times I've told newbies about 3D printing by calling it a hot glue gun on a robot. Wonderful to see it actually done, properly too!
Changing the extruder direction is a one-character change in RRF config.g and you can send the revised M569 command from DWC without even restarting, at least for live testing -- yeah, that's much harder than resoldering all the stepper connections But we all get those project blinders on sometimes ...
You don't need a special bit, just any bit and a sander or grinder or file; DonDon's happy meals made me discover this. Make a single interface board that the crimp plugs go to the Revo board, and then the other end on your interface board just has a row of labeled screw terminals that go out. Blue LED's on the fan head are cool. 22:26 overdoing: Brilliant!
I was thinking about something like this last night. Had no idea how to even begin it, but was thinking of ways to speed up getting material to the build, especially where fine detail doesn't matter. Great stuff. Once I get further along with experience I hope to finally be able to help out with projects like this.
That was awesome and inspiring! Showing all the attempts that lead to the awesome result is a great reminder that everything takes work and we all monkey up stuff all the time. I really think you're onto something with printing super soft or brittle materials. Keep going with this🤘
Dig it. A cotton earbud with isopropyl on it lightly painted around the build plate to print join will release it really effortlessly and leave the glass clean. It's hard to believe how effective it is until you try it, so long as your surface is non porous.
This is probably one of the most ridiculous uses for 3d printing but I'm about it! I love it! I always get excited when I see your videos in my feed. ❤
Unironically, this is probably a good step towards at home filament DIY recycling. One of the biggest barriers to it is that shredding material to a good and consistent grind size and re-extruding it is tough anbd requires tight tolerances in order to get decent quality filament that wont jam your extruder. It's a lot simpler melting down print scraps to 7mm bars in a silicon mold, and then printing with those instead.
This is really rad. I would love to see you continue refining this printer. I really like the design of the original hotend you created before modifying the gun itself. Would be really cool if you kept working on it to solve those problems and turned this into a release candidate quality kit.
I love how crazy your ideas seem. Then you execute them and the rest of us go, "Yeah, why wouldn't it have worked?". Keep up the amazing, innovating project and pushing the boundaries of what we think is possible.
I rellay enjoy your videos :) The basic ideas explored are usually simple in concept yet interesting to get you hocked, but the execution is such a pleasure to watch ! Keep up the great work

I would try a lower heating temp, got glue is usually melted at a much higher temperature than necessary so that it flows easily from a hobby tool. You can use a simple SSR to control mains AC with a digital signal. We use them to control the temperature of hot pots sometimes, usually they're bundled with a kit that includes a basic PID controller, so temperature control is kind of their intended usage. Also getting hot glue off your glass bed should be as easy as applying some 99% IPA, you can apply a generous amount to a paper towel and let it soak on to any glob of hot glue, and it should start to lift easily on its own in 10 to 20 seconds (if not, apply more IPA, and try again, it will work). But this also creates another problem, if you clean your print bed with IPA, you will need for all of it to completely dissolve before printing, or your first layer may delaminate from the build plate unexpectedly. You can also try 3D printing your own glue sticks out of multiple types of filaments. It's just a cylinder. 🫠
Although I agree that I maybe am a bit special😅 I want to be able to change between tools so I don't have to think about changing it each time and keep everything the same
@@properprinting I saw the other comment just before you replied haha. Fair enough there. Still not sure why you'd resolder rather than recrimp but that's probably preference. Hoe dan ook, lekker bezig pik.

Easiest way to get hot glue to separate from the build plate -> Squirt some Isopropyl Alcohol at the joint. It wicks into the bond line and separates with ease.
Super cool stuff man! In theory for testing you could print some glue stick rods using any regular filament you choose, ans then run them through this beast
I think an important take away is how much engineering goes into the humble hot glue gun. It's a delicate balance of thermal mass and cooling to get it to work just right.
Hot glue guns have a temp that makes them easy to extrude using light finger pressure. Good that you dropped the temps a bit as that stuff doesn't cool well after extrusion.
Ha, I'm glad I'm not the only one - for people that don't know how fdm works, I'm usually like "well, it's basically a big hot glue gun controller by a computer"
I always love your vidoes, great job. Did you consider that your heater catridge was maybe just way underpowered compared to the one in the glue gun? You could use a solid state relay and mount the Dremel heater cartridge in your nice new extruder maybe?
Interesting thought! The glue gun was 20W and the cartridge I think is 50 or 60. I could've replaced the heater cartridge in the eventual glue gun, but was done and just wanted it to work xD Next iteration wouldn't include a hot glue gun at all!
i tought about someting a bit after i watched your video, i doubt you will see the comment but with these format the tube instead of filament you can also make it spin while it melt to have an exact extrusion speed with filament this is imposible but with stick if you have something before the melting that catch the tube and screw it into the melting part you essentially have a reliable speed feeding system (this didnt looked to be a problem but i had this on my mind) Also i saw another comment about crushing old print or missed printed and turn them into tubes to be fed into this, once again some kind of hot blades gripping the tube of whatever product and srewing it into the melting chamber look like a good idea since you could just change the temperature and adjust the speed of feeding very precisely. I hope to see you in a recycling video about failed print and support being melt into tubes then printed again...this is so much more easy than trying to make filament out of a blend of plastic or pet bottles, melting under vaccuum maybe the best way to do this or under pressure im not sure but im certain that 3d print has created alot of garbage plastic over the years since it was invented we need something that crushed and melt the faillure then feed them maybe you could even crush a glue stick with the plastic to recycle making the whole tube 50% glue and 50% bottles or supports

Casting wax would have an actual end use case. Typically done with wax blocks and machined on a CNC.
I wonder if with your original design you were getting too much back pressure from the compression of the glue sticks. It would be similar to printing with a soft plastic like TPU I'm sure.

This admits a super convenient path to recycling: mold the material to recycle in a cylinder, then let it cool and use the rod in your extruder. PLA scraps (Bambu poop) and shredded PET bottles are obvious candidates.
great idea!
This would be amazing
For changing motor direction, change M569 for the motor from S0 to S1 (or vice versa) in config.g. Easier than rewiring the motors!
True! I should've mentioned that. I'm switching between hotends and want to keep this the same between them.
Hey quick tip for working with hot glue: Keep a bottle of rubbing alcohol/isopropyl alcohol/ethanol with you, just a few drops at the seam will make any hot glue peel off any surface in seconds!
