Report:
Photocentric3D UV DLP High Tensile

Having heard a lot of bad things about Photocentric3D resins, I decided to give it a try - to my knowledge it's by far the strongest resin on the market.

I need the strength since my parts are a landing gear for a fast 3.5 kg model aircraft.

I was very sceptical because of many negative comments about Phtocentric3D resins on this board.

Settings:
0.05mm/35 sec/2 sec/55 sec/10 bottom layers
20 deg C.

Result:
Hardly any smell, the parts can be cleaned in clear water, cure time I've tried so far is 20 minutes under UV light.
IPA cleaning only needed at the very end to remove some minor surface tack that remained after curing. I would use this resin in my living room.

Very, very strong, very hard surface (after curing it's nearly impossible to cut), yet slightly flexible, not brittle at all. A lot stronger (35% more tensile strength) and more rigid than the PA12 that I used for the same parts when I ordered them from Shapeways.

Takes a long time to print, of course (3:45 hours for the part shown). Very easy to remove from the platform. No measurable shrinking. Hole diameter very precise, even for deep 1.5mm holes.

The attached pictures are my first attempot with that resin.
They speak for themselves. The smallest details have a depth of 0.15 mm.

My opinion about that resin: Absolutely perfect.
