Hi everyone, A few months I started trying to make my own resin. After gathering all the necessary chemicals I think I'm close to the final recipe. The recipe is the following: -1 kg resin (1,6-Hexanediol diacrylate) -10 grams photoinitiator (Phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide) -5 grams pigment (Sudan I) This resin seems to have some potential. I tried to print some objects (basic hollow circle extrusions) with my SLA printer. I printed with lasers with a wavelength of 405nm, varying in power ranging from 100 mW to 300 mW. All these prints however, have been warping while printing. The first few layers go well, but after that the object just warps. The build plate is made from aluminum and the adhesion is very well when I check it after the first few layers. So it seems the resin just shrinks/warps when it has been cured. Does anyone have an idea how to solve this?

Did you get it working? What printer do you use?]]> 12345lance Polymer Working Group Fri, 13 Dec 2019 16:59:50 -0500 https://reprap.org/forum/read.php?184,791779,791779#msg-791779 https://reprap.org/forum/read.php?184,791779,791779#msg-791779
