Slice Pause for Higher Viscosity Resin and Fewer Voids
I lucked into a 55-gallon drum of clear UV cured resin, but I suspect it has a higher viscosity than Peachy Juice, though I may be able to thin it. (Does anybody know the viscosity of Peachy Juice (in centistokes or Zahn cup) or the maximum viscosity resin that Peachy is designed for?)
Regardless, it should be possible to install a solenoid valve in the Peachy drip tube, and set the drip rate near the maximum rate. Whatever the software determines the slice thickness to be, when the drip count is reached, the computer could raise a flag on a USB port and pause for a programmed interval before scanning the slice with the laser. The output signal would close the solenoid valve and stop the drip during the pause interval. This would allow time for the resin to flow over the previously-exposed layer and any bubbles to pop or voids to fill.
After the slice is scanned by the laser, the flag would drop to open the solenoid valve and the process would repeat. Even for normal low-viscosity resin, this modification might allow faster printing or better quality prints. Anybody know how to make this hack happen? What programming tools do I need to modify the Windows version of the Peachy programs?
Anybody want a sample of the resin to experiment with? It is Quakercoat 021-UV Clear. It can be thinned with Sartomer 5102 monomer (not sure where to get that yet).
Thanks, DonS
