I'm working on the extruder right now, one of my goals is to keep it within the face profile of a standard nema 17 (42x42mm). This of course comes with some space issues as I'm trying to make it...

Augers are not super precise with their deposition, filament makers use an auger screw, but they use the tension on the filament to control diameter. Augers are not positive displacement pumps so...

I think you're really missing the point of why I started this thread, and my previous replies.

I think the volcano also has a more powerful heater cartridge, and I understand that the heating of...

I'm not sure most NEMA 17 motors are rated for 24V. Also, this thread is about designing an extruder, not buying a ready made solution. I'm not really planning to design and build an affordable...

I wont be using a metal gearbox or injection molded parts like the titan, since they are too heavy, expensive, or both for my application, so I'll have to consider the backlash of printed gears. That...

I've read that gear reduction actually makes retraction less precise, due to backlash in the gears. I'll look at gear reduction, and I'll probably end up making a geared and un geared version of my...

Have you used either/or any similar extruders? The flexion isn't too different from any other extruder, the brush is there because the deeper hobbed gear grinds harder filaments like pla and abs (non...

I'm hoping to make a high speed printer, definitely above 100 mm/s for pla (thinking 150+). As for flexibles, with some minor modifications to my mk8 style extruder I could get TPU printing at 60-70...

I fully intend to make sure there is a fully supported filament path, regardless of any other choice I make for the extruder i.e bowden/direct drive, geared or not, single or double sided drive.

As you may be able to tell from my other thread, I'm designing a printer. And a big thing I'm trying to decide on is the extruder (that and build area but that's easier to customize later).

The...
