220mm Twisted airfoil propeller blade printed with the 2.85mm Carbon Color Fabb XT-CF20 at, 0.5mm steel nozzle, 0.2mm layers, 50mm/s print speed, 255° print temp, 65° bed temp,1.5mm retractation distancedanilius wrote:Very fascinating solution. I would love to see what something printed from the far left hand corner to the near right hand corner (essentially along the natural axis of the rod) looks like, whether the torque on the rod results in any feed differences from the nearest to the furthest positions.
Sorry somethinh wrong on the first video, it's B&W and there are distortions

Re: Zero Gravity Direct Drive Extruder
Looking forward to this!
Also will you share the .stp files for the bed-holding arms?

Very, very impressive. No if I only knew where to find that square rod and the thingy that goes around it, I would give it a whirl.

Re: Zero Gravity Direct Drive Extruder
How are things progressing? I have seen Neotko's pictures/videos and they are really impressive
I have a need to print a lot of flexible stuff this spring and this extruder really looks like "the" extruder for such materials. So it would be nice if one could at least know what hardware parts, apart from the printed parts, that are needed while the rest of the design is wrapped up.

Re: Zero Gravity Direct Drive Extruder
Very nice desgin indeed!
Do you have any numbers as to how much this printhead weighs effectively?
I suppose the square steel rod doesn't have to be fully counted to the weight, but at least in some part it does affect the x-y-movements...
These are the moments when I wish I had access to the simulation part of Ansys software. But it's a little bit off my budget
I'm in the process of making a small & lightweight printhead myself, that's why I'm asking
fyi, I am sitting at ~240 grams total weight for the printhead and direct extruder drive, excluding bowden tube. My design is not tested yet (printing the components atm) but there will soon be pictures!

Re: Zero Gravity Direct Drive Extruder
It's alive and kickin'
Awesome mod and the attention to details is amazing
If you are considering this...take your time and read and digest the information provided...because it's a lot of files and things to pay attention to. But rest assured...the time spent will be worth it

Re: Zero Gravity Direct Drive Extruder
When printing the flexible parts I noticed that the "motor support spacer" doesn't reach through the "yaw holder" so there will be direct contact between the "yaw holder" and the "motor holder". Is it supposed to be like that?

Re: Zero Gravity Direct Drive Extruder
Motor holder uses a 2mm spacer so it can spin freely on the bearing.
