This 3D PRINTABLE Extruder works with TIMING BELTS!

Күн бұрын

In this video I show an experimental 3D printer extruder which uses GT-2 timing belts to push the filament. This doesn't require a spring-system which makes this easier to print. This is the first video of a series in which I'm going to experiment and explore extrusion techniques. To make stronger 3D printed parts.
I 3D printed everything out of high-performance engineering resin by 3DResyns on an Anycubic Photon Mono X 6K resin printer. This went very well once tuned in correctly!

3DResyns contacted my about the thick Nylon-like resin and it turns out that they sent a HV High Viscosity version tuned for high light power DLP printers. They’ll send me a new bottle with LV Low Viscosity version, for non-heated printers and for low light power LCD printers. For the next resin video I’ll make those gears out of this stuff! Happy 2022!

That's very encouraging news! It's great you had plans to solve the heated chamber issue, but even better that it was just a resin mix-up and no workaround is necessary. I have to say though, the comedy and relatability of unmet expectations in the storytelling was so entertaining 🥲

The resin prints you did. Did the holes for the screws and nuts just come out in perfect dimensions or did you have to drill and clean them out? I'm guessing not, and that's amazing. I had a thought for the belts, do you think you could print them from like tpu or other flexible filament? Are there flexible materials for resin printers? I was thinking maybe draft them in a circle shape and use a large nozzle in vase mode to get the most consist print. Even with well calibrated linear advance/pressure advance, it'd be nearly impossible to get a belt printed that was exactly the same thickness all the way through. When dealing with retractions, speed changes, layer changes, etc there's always a bit of variation in wall thickness, for some things it may not matter if the thickness changes, but here it would. I really liked the extruder you made though, it has inspired me to try learning cad again, hopefully it goes better than my previous attempts😅 thanks for the vid!

@@josephbodhorn6511 Thanks for your awesome comment! I drilled the holes for the screws and the filament path because that was easier. The bearings and inserts fitted without modifications (after a couple of attempts to be fair). There are flexible resins and this Nylon-like resin is flexible below a certain thickness. The only problem being that this stretches too and therefore timing belts have fibers in them. Awesome that I inspired you to learn CAD again. This is so useful!

Cool looking back on this, started as an idea, became a thing, and then someone took it and made it even better. Papilio just entered public beta, and its a "refined" version of this, shrunk down, and adapted to use the same extruder mount as the sherpa/lgx lite. One of the unique changes is the drive gears for the belt of the Papilio are like a hobbed gear, so the belt is actually contacting more of the filament, and it stays in the path nicely. Not to mention it's a lot smaller in lighter. Either way, thanks for being one of the first people to actually try it, its fair to say it was inspired from yours. Keep up the good work, and keep trying things!

Very nice implementation! I've been using a selfmade belt extruder for 4 years. Its still going strong. Its way more bulky than yours though. Im surprised yours works without a tensioner. Mine has a friction sweet spot that needs to be dialed in (grip vs motor power needed). I was really worried at first that the friction would change over time, but it seems to be really stable.

@properprinting 2 жыл бұрын

This is so good to know, thanks! It did skip at that extreme purging step at the start of that test print (the stock extruder did too) and I still have to add tensioners. Well, I added them but they tensioned it too much. It worked with the FDM printed version out of ABS, but because the PMMA-like resin is so much stiffer, it didn't bend as much causing too much tension. I'm glad yours seems stable, this gives hope :D

This is excellent. You need to have a simple spreader on the belts the same as the belt driven tractors that are made now to provide tension. This would be ideal for production on the belt extruder unit. The color looks fine. A copper tone is a nice structure. You are doing the right thing with this innovation. Keep working on variations and this will become a simple and highly functional filament handling mechanism.

@ericbommer2280 Жыл бұрын

I really think this is genius and has really inspired me. The current metal gear extruders, while they work have such a small contact surface area to the filament, which I think really limits their capability. After seeing your design, this has caused me to search further into using a belt over gear fed systems. From your inspiration I’m thinking about a Bowden design(Could also be a direct drive), that will use a single belt pressed against a roller. The roller will have a small grove to hold the filament in place. The roller will be hashed (Knurled) outside the grove to increase the friction between the belt and the roller to reduce slipping. The belt will also contact over 50% of the roller to reduce filament slippage. I’m even thinking of following the idea of a sailboat windlass which would allow the filament to be wrapped more than once for even better slip resistance. Kind of amazing, how things can fall together while just leaving a comment.
