For example: MakerJuice SubG+ shrinks at 3.5%
1+3.5% = 1.035
1.035^1/3 = 1.011533...
So now you can scale your part by 1.011533 in x, y, and z. This should get you close and you can tweak from there.

I didnt see how I was going to dial in the cure thickness. Other than trial and error. But your approach is alot more elegant. I also wanted to fine tune the system for a true 1:1 plot but using your approach it would be easy to find that number. This should defiantly be in the software. Once you measure the XY and Z the software should be smart enough to tell you how to scale your part and cure time. This is a must have.
Just ordered B9R-1-Cherry Resin It seemed to be well proven so I thought it would be a great start to my collection. What else have people tried with EXCELLENT results? What about Formlabs grey or white? Solarez 3-D Printing resin is sheap but no pigment.
Also what are people coating there VAT with. I am undecided what to do about coating, taping or just do nothing.

I have Mach3 running my printer so I have a macro I use to expose a little test square. I put a small puddle of resin in the tray and try different test exposures. I remove the cured square and caliper it to check the thickness. I have to re do this every time I try a new resin or change the color or concentration of the pigment. Maybe Steve aka PacManFan could add a feature to his CreationWorkshop to help those using the ardino controllers find the correct exposure time.

I think you need to add some pigment so the light doesn't bleed up to the next layer or the surrounding xy voxels.
Keep it as cool souvenir though.

Any feed back would be great!
Build Setup
CW VER.RC
SLICE = 0.100mm
EXPOSURE = 7500
FIRST 3 LAYER = 15000
LIFT = 2mm
To break the bonded resin I only lift the part.
RESIN
Marker Juice Clear SubG+
I think this was a bad idea having a clear resin will cause the cure to be more sensitive to light. I am considering purchasing so black die to reduce the transparency.
After a little cleanup.
