  • Edit: This is not in response to the Video: That is one way, but with different filaments you always have slightly different diameters. I was referring mainly to slicer settings, where the extrusion multiplier is. In cura, it’s called the “Flow Multiplier”. I would recommend printing something like…

  • What happens if you go up to a 0.3 layer height, is it more or less visible?

  • I’ve had this problem before, and I think the reason Antonio_Bencini is mentioning it is because it becomes more pronounced with over-extrusion, which it looks like you have a little of. I find that I run an extrusion multiplier around .898 and I get much less of it. The last time it was bad on one …

  • What is on the bed? It looks like there is something on the blue tape. With the unheated bed, I found that I needed to use plain white masking tape, instead of blue masking tape. I would get corners peeling up with the blue tape on an unheated bed. Also, try lightly sanding the blue tape. As mentio…

  • I use a Simple Metal, and I agree with everyone’s comments, but we really would need more information. Is the filament extruding? Does it bubble or steam when it extrudes, or do you hear a popping sound? Does it stick to the bed? If not, what are you putting on the bed? Are you getting excessive…

  • The filament is made of the same resin as Delrin, a brand name of DuPont, I think. It typically comes in sheets or blocks and is milled. It is very strong and wear resistant. I wanted to use it to make some mechanical parts that would be impact resistant, as PLA and ABS tend to shatter with impact.

  • I’ve been trying a bit here and there to get a spool of black acetal filament to work with my printrbot simple metal with heated bed upgrade. It doesn’t want to adhere to blue tape, or plain masking tape(which has always worked better for me than blue). Today I was able to get it to stick to the ta…
