Hi coaster19.
I believe that both printer work with Vat Photopolymerization technology. Form 1 with SLA (using laser) and Solidator with DLP (using projector).
Solidator said on kickstarter site:
"Resolution impresses.
Solidator can print features as small as 270 microns (0.0106 inches) and layer heights from 100 microns all the way down to 30 microns. This leads to impressive results.
Technical Specifications
Build Volume: 280x210x200 mm (11.02"x 8,26"x7,87")
Number of Voxels in Build Volume: More than 1.5 Billion Voxels
Z-Motor resolution: 10 microns (0.000393")
Typical layer height: 100 microns (0.00393")
Minimal layer height depends on the material used.
The Z-Motor is able to go down to 10 microns layers.
We currently support down to 30 microns with the solidator resin.
Minimal Feature Size / XY-resolution: 270 microns (0.01063")
wihtin a 280x210mm build area..."
And Formlabs say that form 1 work with 25 -100 microns resolution.
Face that I'm confused about what's printer has better resolution.
Maybe someone could compare both printing on CES and come here to say something about their smooth surface. If Solidator will be there.
Another 3D SLA printer promisse is FSL3D that confirmed on CES.
Thanks.
Excuse my basic english.
