So when the new vats are released will there be

and the FEP printing guide:

Could I use the FEP vat with DLP resin without degrading or damaging the FEP film?


#23

The polymerization reaction probably won’t fog the film as easily as PDMS. However, the resin may bond more tightly to the FEP than it would in a DLP printer. You will likely have to adjust the laser power carefully.

I have actually just pulled a print off with relative success. No fogging, but the print is thicker than it should be. I figure my power is too high and I am over curing a lot. Trying again now

Remember that DLP resin has a much higher titer of photoinitiator than laser SLA resin. This means that out-of-plane energy will cause the resin to polymerize. Were the details of the print washed out as well?


#26

The details were slightly washed out.
They seemed more like everything is softer around the edges and not as crisp as the Peopoly Neon.
I am using the Photocentric UV DLP Castable blend.
I have been reducing the laser power incrementally. It seems as though 49 is the sweet spot.

In this photo you can see the waxcast on the left (The only thing I have ever succeeded at printing with waxcast) and the photocentric on the right.

The waxcast is pretty crisp and the photocentric has a bit of a minicus in each of the little corners.
Both are printed at 100um
