Results so far.
I tested with shorter exposure times like Mike advised just above this post.
Before testing I calibrated the build table once more.
What happened is that the PDMS not ruptured after about 700 layers. So that is positive. (The PDMS is still lying straight on the bottom of the VAT and seems not to be harmed.)
Though there is still an issue. Because the entre build fell off the build table after about 700 layers (total is about 2100 layers) So the actual printing stopped kind of halfway.
I aborted the print at the moment I saw the build swimming in the VAT.
Question is: Why did the product detach from the build table and could it be a good idea to cure the four base layers a bit longer hoping that it will prevent the next build from falling off the build table.
Thanks in advance for your thoughts and opinions!
Further on, the last print settings (This print was aborted because the build was swimming freely in the VAT after about 700 layers)
