Bad prints from form1 after switching resin

Support & Troubleshooting Form 1/1+
1

I bought a used form1 a couple of weeks ago. It came with a bottle of applylabswork white resin. Ran a couple of prints with what was left in the bottle after getting a new resin tray and cleaning everything. Those came out great, not one issue. I ran out so I ordered a bottle of expert gray from them. When I ran out I completely cleaned the build platform and resin tray with ipa and pec pads.

It arrived yesterday and I printed out a test rook and it came out kinda gunky but I thought it was because it was printed very small. Started one of the same models I had printed out with the white just to compare it. Ill attach pictures of it. I changed the settings in preform to be gray v2 which is the newest update available in preform 2.2. Ran it overnight and came back to this mess. Layers are skewed, nothing is circular. After that I sifted out the resin with a comb then I printed out a half inch cube as a test and it came out even worse. Wondering if anyone could help me out with this. I was so happy with the results of the first resin.

The cube is also 1/16" short on one side. and the supports for it are slanted

Mangaged to get a cube with decent surface finish. I had to rotate it to get it to do that. Its not a cube though trapezoidal prism is more accurate of a description.

Hi @Nelsoneaton01, thanks for reaching out. A Form 1 - nice find!

What’s happening essentially is that the Print settings for Grey v2 are not optimized for the ApplyLabswork. Unfortunately because of the non-Formlabs material and the age of your machine we don’t have additional guidance or validation on materials outside of ours.

You’ll have a better chance using our materials (Grey v4) which would be more closely optimized to Form 1, but again, based on providing the best tech possible, we’ve optimized our resin settings to the Form 3 and Form 4.

Thanks for sharing your learning curve, and we’d love to keep learning as you ask and share along the way!
