Hi,
We have a lab where we sometimes need to re-use the same tray for different resins. We usually scrape the tray and give it a quick IPA wipe to be sure, but we are wondering if too thorough cleaning to get the last drops out might actually do more harm than good, ie. is squegeeing most resin out enough, or should the tray be wiped clean?
It has been mentioned previously that having a "small" amount of previous resin remaining after scraping shouldn't affect printing, but so that we can put a number on it and know that we are complying with official manufacturer instructions, could I get an estimate exactly how much is a "small amount", in ml or percentage?
For example, when moving from gray -> clear resin and using the same tray, is having 5 % of gray resin remaining in the tray after scraping and having it mix with the clear resin ok, apart from any potential cosmetic issues?
