My printed parts appear very rough. I used auto-orient and auto generated supports. I am using grey resin from Formlabs. The layer thickness I used is 0.1 mm, despite what it says on the bottom of the screen shot. [image] What could be causing this roughness? How would I go about fixing it? Thanks…

Just wanted to add that I’ve been seeing this kind of bubbling too on various prints I am doing with grey resin at 0.05. It is usually (but not always) within 2-4 cms of the base and seems to “hit” in a limited horizontal region. But sometimes on thin-walled stuff, it continues throughout the wall. …

[image] geobot3d: m unlikely that specific dust particles would have such a universal effect on a specific region of the model. Does this approach make sense as a way to isolate mirror-dust as a cause? You know, I bought an air blower for photo lenses and I plan to inspect my mirror when the…

I agree Cesar that dust particles would not cause uniform problems. I think he just wants to do maintenance.

I don’t know how much it would impact your prints, but after using the compressed air duster on my mirror today, I did notice some improvement with regard to roughness. Take a look below (old part on the left, new on the right): [image] [image] Though the final finish isn’t perfect, it will work…

looks much better. have you changed orientation? I am starting to think the flat areas tilted at 45 degs or I should day not perpendicular to the build plate seems to get artifacts.

Wow. Same form file? That’s quite a difference. I did a retest on mine to rotate only by 180 and The bad area ‘disappeared’. I am starting to believe dust could be the cause. Bums me out tho - I have been pretty careful in my print environment. If true, this thing needs a clean room.

It’s actually the same orientation as the original. There was a decent amount of dust to remove since it was my first cleaning of the new printer’s mirror.

From now on, I’m certainly going to clean the mirror more regularly. However, I think the bulk of the debris I had to remove came from manufacturing and shipping. Nonetheless, I think it’s a good idea to include mirror cleaning with regular maintenance of the printer.

You don’t happen to have a picture of how bad the dust was to give that result do you?
