Fired up the Wanhao D7 (DLP printer) and made a few resin prints. The red fish is casting resin and the owls and rook are Wanhao black resin. All the resins are about a year old, so I wan't sure if there was a do not exceed shelf life.
I did my "super clean" post process with IPA, ultrasonic cleaner (detergent), heated vacuum chamber and UV cure light. The ultrasonic step may be overkill as I think with the vacuum and UV light, a tiny bit of uncured surface resin may assist with a bit smoother finish cure.
For casting burn out the very slight (tacky) uncured surface resin is a problem for the investment material, but for normal prints, it may ba benefit. I'll explore that with future prints.
New Wanhao resin is on the way, so I will have some fresh "juice" for the next prints Red, green, and grey.
That's an indication there will be more prints to come from the DLP printer.
