MRRF: Innovating Extruders and Dissolvable Filament

MRRF: Innovating Extruders and Dissolvable Filament

Think laying down molten plastic on a 3D printer is as easy as squeezing plastic filament out of a hot tube? It’s not, and anyone who had a 3D printer in 2009 would tell you as such. There were hobbed bolts that stripped the plastic into a gooey paste, extremely large x carriages that made everything wobbly, and nothing worked as well as it does today. Technology marches on, and this year’s Midwest RepRap Festival had people showing off the latest advances in pushing plastic, and something that hasn’t seen much use yet – dissolvable filament. Bondtech’s V2 Extruder When we saw the Bondtech extruder at the last MRRF , it was a device that could push a lot of filament very hard; the promise of two knurled or hobbed gears pushing filament through a hot end was very interesting. Here’s a video showing the Bondtech extruder pulling filament with 20 kilos of force. This year, [M...
