I´m producing my dental models for making dental aligners on my UM2+ wich by the way works perfect. I use PLA spool and infill of 25-30% but when trying to make the aliogners on the vacuum machine they shrink. Shoul I increase the infill? or any other change in the process to avoid this ?
How to print with two different procesess on one single item? Firsts layers printed at a different thickness (0.150) than final ones (0,08). Possible ?
