Eagle eye ;-) The problem with the granules extruder is that a higher volume of plastic resides longer in the "tube" than it is the case with filament extruders. Even with the temperature set to 190°C, which isn't that high for filament extruders, it seems too much for this one. I will talk about those issues in the next video, when I try to shrink the size of the extruder to the necessary volume. I usually print nothing but construction elements, color doesn't matter to me. But since multi material is an option, I will at some point equip a printer with more than just one extruder. Stay tuned!
Thanks! Yes, but making filament is more than just extruding. The cooling path of the extruded plastic decides whether the filament diameter is constant or not. Speed and retraction will be treated in coming videos - stay tuned!
You're Right, because of Diameter variations, that would be inefficient. I think closed Loop on the extruder flow will be (when ?) a huge step forward : quality whatever Diameter inconsitencies
Same here: Bad hardware engineers always say "The electronics and software guys must fix that!" ;-) I will eventually turn this into a filament machine some later. Stay tuned!
Haven't tried that. Wax grains are soft and sticky, even at room temperature, which makes this material tricky to handle. I might give it a try, but I have an other type of print head in mind for wax printing. Stay tuned!
It is a Zonestar QR2 that went out of production a decade or so ago. I will convert a new printer model in the not so far future. Any ideas which printer I should modify?
Either a Creality or a Prusa brand. I believe they're partially open source. They're among the most popular. I dont have either, just like you I got my hands on a cheaper older model and fixed it... XD That being said, if i had the money I'd buy a Prusa mk4.
Creality and Prusa are my favorites as well, for the same reasons. I have a Creality CR-10 and I really like the open frame design, that makes the conversion more easy.
Well, considering that this is an early stage of experimentation and that I haven't seen any direct granules extruder that can print small structures better, I am still highly motivated.
it's mostly because he lacks decent part cooling. the extrusion consistency looks very promising and already pretty good considering the 3d printed construction of it all.
On the contrary it’s an already excellent outcome given that it uses 0% virgin granules, can handle rough grinding and is implemented on an extremely cheap platform (3D printer) with sketchy overall accuracy. This direct granulate add on is very promising 👍 Esthetic characteristics of functional parts are usually irrelevant.
crushed plastic looks so delicious, like candy
...but printing with sugar is the better raw material for delicious prints: ua-cam.com/video/ea2dfdTszqM/v-deo.html
the viscosity seems a bit low, perhaps take the temps down a notch. EDIT: i was hoping for a multicolor print

@@HomoFaciens I'll watch the whole series, this video popped out of nowhere, to get a better understanding of the works.
Great work !
Would this setup be modifier for making filament ?
As on a spoll , speed, retractation are no more a limitation
Thanks!

Can you use wax with that type of extruder
Haven't tried that. Wax grains are soft and sticky, even at room temperature, which makes this material tricky to handle. I might give it a try, but I have an other type of print head in mind for wax printing. Stay tuned!
love the idea. Like, printing a model for a lost wax metal casting process ... interesting.
What printer did you use? Is it modified? I feel like getting one

Don't want to demotivate you, but that looks terrible.
