Polycarbonate prints
-
100% polycarbonate black is very hard to make look good as it's shinny and refracts on every imperfection. very strong layer bonding, good enough to not break on layer lines. this print was 0.25 layer height.

@nz_andy any chance you'd be willing to divulge some specifics on your xy drives like servo or stepper, step angle, on board or external drivers, screw lead, micro stepping and speed of external perimeters? Im always interested in gathering more info related to the patterns created on external surfaces (the ones I dont think are necessarily caused by resonance)

@3dpmicro Sorry for the late replay....
Actually the pattern you can see was a result of a bad bearing on one end of the leadscrews. It's good having more than one of the same machine, this allows me to see if the other machines have the same issue. (they did not). The bearing had no brand name and was bad from the start, I replaced it with a brand name bearing and it's all good now.

Looks great - but super spammy ...

@sputnikoc3d I have to laugh at that comment, we are a 3D printing business and that was an Instagram post to promote us. This is how we pay our rent. (I don't think i'll get business from this forum) but people can see what we can do with Duet3D. Thanks for the comment.

@nz_andy Those parts look awesome, I wish I had the capacity to print PC and Nylon. Have you considered the latter? That's been on my list for quite a while but it's rather difficult, although I figure it isn't so far away from PC.
It would be neat to see some parts being printed, would you mind sharing a video showing that?

@chrishamm thanks, is there a way to drop a youtube video in here or can it only be a link?
Below is a picture of a nylon 6 print, works as well as a Multi-jet fusion part, maybe better. I think FDM has a lot of future, it was on the back-foot for a while but it still has a long way to go. (plenty of good refinements coming along) our latest print heads are making a big difference.
