Suddenly I have severe problems printing with Gray. See attached images. I have it in a dedicated tank, and other resin/tanks print pretty well. Any idea what’s going on here?
It was a classic case of settling pigment. I did “stir” the resin each time before printing, but the pigment appears not just settled, but sort of adhered to the bottom. I used a plastic putty knife - in a pushing/scraping motion, not toward me in a dragging motion - to clean the PDMS back to clear. Prints great now!
It happens to all my gray prints. I definitely use the gray setting in PreForm and give the resin a stir. I was just reading another thread where someone suggested exposing the PDMS to air for a while, which I do not do (Resin stays in a dedicated tray). I’ll try this.
