It’s really only the boundary layer of resin and IPA that counts when cleaning a print. The bath itself doesn’t do anything.
I thought of a more efficient and economical solution.
I’m now using a peristalic pump to hose down the prints. The force of the fluid stream strips off the resin quickly; a couple of minutes seems to do the trick. It’s like the difference between a tub washing machine and a front loader.
The prints are clean in a fraction of the time of manual dunking or wash station times, and I use a very small amount of fluid; just an inch on the bottom of the tank, which gets sucked up and forced onto the print. It then flows down into the reservoir of fluid on the bottom to be cycled again.
It’s not only faster, it’s way more economical and less wasteful. Dirt cheap compared to what Form is suggesting for the 3L.
I’m using this: (Stepper peristaltic Pump 24V Small Intelligent Variable Speed high Flow lab Liquid dosing Pump Kamoer DIP 3 Rollers 5-670 ml/min BPT Tube 4.8 mm ID x 8 mm OD), $150 on Amazon. You have to buy the hose separately.
This model delivers about 700 ml per minute, which is fine for Form3 size prints. I might go for a larger flow for 3L prints. I’ll report back after my 3L is delivered and in use.
