Immediately tested it on a UV resin.. Peels amazingly fast & clean

I think the translucent sheet is acetate.

The FTI 230 V-Flash® Modeler uses a clear acetate film (cellulose). Has acetate film been tried as a release substrate?

Do you think the acetate film technique has an advantage over using a vat, e.g. printing finer details without distortion?
I'm thinking that there is more work involved to make the resin film deposition tool, than it is to fabricating a vat.

Note how the build platform is releasing from the acetate film. It appears it's raising one side then the other. I made the assumption that this was being patented by Stalactite 102, $2360, Innovative decoupled dual peeling system (patent pending)

In this video you can see the build platform rocking back and forth on the up stroke to initiate separation.

In this video you can see on the down stroke that the build platform rocks back and forth before settling onto the acetate film.

Looks like 3d Systems discontinued it?

The V-Flash operates at about 0.4 inches per hour.

What are your thoughts on this technology, is it some thing you want to try, advantages/disadvantages?

I'm looking for more information on this separating/coating arm.
