Borosilicate + PDMS

Petri borosilicato + silicone PDMS + Pasive Tilt:
Pros
  • It is easier to achieve maximum XY resolution with no need for adjustments.
Cons
  • Changing the PDMS every time it wears out and leaving it to harden is a process that can take up to 48 hours. It is therefore advisable to have 2 petris.
  • PDMS is hard to find in some countries, although it is available through Amazon or Ebay. QS Solar and Sylgard 183 are the most widely available brands.
  • Vacuum forces during the resin curing process are proportional to the surface being projected. The greater the surface, the higher the build platform will need to be set for delamination between printed layers. Printing time is therefore longer.
