SLA printer notes:rnYou will want to print with the face of the Gem towards the build plate.rnYou can use mini or full raftsrnI was successful with two supports touching the face of the GemrnThe Durable resin will add some translucent effects if you use a dye to color. If you use a pigment or fingernail polish the Tough1500 will have a better defined edge.rnrnColoring the Gems is the next hurdle --- rnMethod 1 rn-- use fingernail polishrnrnMethod 2rn-- use CMY dye from inkjet printer -- I was able to dye with this method even after a cure rnAs a side note make sure to wear gloves, or you will have very colorful hands for a week.
