I got Form 3 at the end 2019. Still printing on the basic black resin on the highest quality. But all parts I print are little bit oversized. I see all dimensions are around 0,1 - 0,2mm larger. It means holes with the expected inner diameter 3mm are actually only around 2,9mm, parts length are around +0,1mm longer., wider…etc. I still need to do a lot of sanding with the sand paper.
I work with the endineering prototypes. Smaller mechanical parts with the tolerance around 0,1mm. So when I print components, I canot assembly unless I sand all dimension. Which is sometimes crazy :-(.
This “oversize” is directly after printing and washing in alcohol. After curing still same.
Is it normal? Just printer limits? Or any more expensive resin could have better results? My firmware is rc-1.4.4-468
Thank you for your advice. I could not find similar topic on this forum.
