This is a question I am sure many of you were wondering about. It was just answered by the creator of Peachy Printer.

Thor Johnson asked:
A completely odd question -- how does the right amount of resin get in?
Do you pour 100 ml on top at the start of the build and then suck it back out at the end, or is there a drip feed (or something like that) for the resin as well?
Also, is there a quantity break for shipping -- I'd like to get 1l of plain resin, and say 6*100 ml of colors and 100 ml of each of the flexible ones, but at 100ml, the shipping cost (to USA) makes up half the cost....

@Thor Johnson
The program will tell you how much resin to add before you start your print, any extra resin left over will remain, and will be reusable in your next print. If you are not using the Peachy Printer right after your print the resin can be syphoned off to be used at a later time.
