“Hear” is the word actually… It’s much more silent to begin with. I left mine quite tight, so it’s more effort to move, let’s see what it does for durability. Keep you posted.
@Michael_Memeteau axial ridges on IGUS bushings for axial motion are provided as a mean to collect dirt away from the contact surface.
Is twist small enough to keep this feature effective?
Haven’t seen much about the IGUS filament but it’s a very intriguing product. It may be one of the first open implementation of a product by the original company that if anything my improve the value of their offering. Ive tried to print bearings and love how quiet they are. but keep going back to LM8UU ball bearings. I have not seen the IGUS filament here but would love to try this. I was thinking maybe with nylon. I’ve had interesting ( read poor) results printing it but the raw filament like this may be good.
this is my attempt at creating printed bearings. http://www.thingiverse.com/thing:906972 my thinking was extended length to keep it stable but minimal contact surface to keep it moving consistently. They all have the same contact area. I should redo them to fit un extruded filament and test again,.
@Gianfranco_Pellacani Thanks for the info, I was actually wondering what it was for… and the answer is “no” (10 ribs, 36º twist from top to bottom, so they covering exactly the whole diameter). On the other side, they are operating in a relatively clean environment (3D printing). Even with the current design, the dust should be pushed away at each operating side of the bearing movement and should keep the rod clean, that was my thinking, but you probably have the experience and the reason to tell otherwise. I’ll would be curious to hear it… Thanks anyway…
@Michael_Scholtz Depending on where “here” is, if you’re a marmite amateur, I would assume UK. IGUS should be able to deliver it to you from Germany (that’s where mine comes from). Your attempt is also an interesting approach. What I like about the ribs, is that you can actually design a part directly to be fit them without the bulk of regular bearings. For low mass part, that’s a very good news (I’m thinking fast printing head like on quadrap for example). Thanks for sharing.
