Hard UV Resin (Grey)

Conclusions

Let´s jump to the results immediately. This resin costs 45€ p/kg and is suitable to be used with a Form 1+ resin setting FLGPGR02 (Formlabs Grey Ver. 2). Unfortunately, the printed model to test this resin has low poly count, to exacerbate even more, it´s circular and we can clearly see the flat faces around the perimeter, therefore I can´t say for now how good is this resin to capture fine details, but I´m not impressed. It was used IPA to post process the part, this is because I suspect that to successfully clean the part using only water it´s required to use ultrasonic bath´s.

My First Procedure

I´ll leave notes on this first attempt for future reference, and I will update this thread with newer procedures to develop a systematic approach to successfully print those challenging parts with small details and thin walls.

Procedure nº1 (no resin on the tank)

Shake the bottle vigorously.
Ensure the VAT is clean and that existing clouding will not affect the print.
Pour the resin slowly in the tank, preferably on a corner.
I used the formlabs funnel as a test part.
For the first attempt it was used 100micron layer height and as material the formlabs resin grey version 02 (FLGPGR02).
After printing, 1st IPA Bath during 5min and whirling the part inside the bath.
Then a 2nd (clean) IPA Bath for 2min.
Leave it to dry and then wash it with water.
Post curing with UV light approximately for 60min.
