Hello,
I got a couple of years old Form 3 from my colleague and I’m printing with Tough 2000.
I always get those bad surfaces on the printing bed side. I understand that there are bumps from the support. But beside this effect, the surface is kind of convex, bumpy and shiny.
I cleaned the part in an ultrasonic bath and cured it in a formlab cure
Is this normal for an SLA printer?
Thanks for your support!

@mette_drk Thank you for your inquiry. The side of the models facing the build platform with supports tends to have a less smooth surface due to the extra material used for the supports. It may be necessary to do some additional finishing on that side of your printed part. I have a guide for you from our support site with some basic finishing steps.
I hope that helps keep you printing. Please feel free to open a support ticket with any addtional questions or issue you may have. We’re always happy to help.
Unfortunately this really happens, and it is kind of intrinsic of the process, at least till a company solve it.
But here a tip to solve this: I saw that the angle between your part and the bed is approximately 35 degrees. If you set this angle to be above 45 degrees (60º for example), you probably will have a better result in this face, on the other hand you’ll lose some accuracy of the holes, maybe you’ll need to make them a little bit bigger (0.1 mm ~ 0.15 mm)
I would attempt to print flat on the bed from the short side (print is perpendicular to the print bed). this really depends on the mating surfaces you have, but generally such a boxy shape would lend to printbed printing. It may fail, given the geometry, but something to try at least once to achieve the surface quality needed. Is the bumpy side functional? does it need to be flat/smooth?
Looks like a print error, could be an issue with layer shifting or adhesion. Did it happen partway through the print?
It happened again and again over several parts…
Hi @mette_drk, sorry to hear you continued to see these issues!
Could you please provide more information on how the problem presents itself?
For example: Do you see surface quality issues only around support marks or in other areas as well? Does this occur with several materials or only Tough 2000 Resin? Are the tank and resin cartridge within their lifetime?
Alternatively, please feel free to open a ticket with our support team who can help examine your specific issue.
