Re: Daylight Polymer 3D Printer

40x5W 410-415nm. Curing time about 2-3 seconds at half power and with the old prototype led array. I hope to achieve a better curing time.

Re: SLA printer build

The adjustable mirror allows to tune the laser in correct angle of projection much easier. In this case It is not necessary to move and adjust the box or the galvo. And something else. You can put plano-convex lens on the bottom of your VAT for better accuracy.

Re: pressurized FEP vat

The main problem is how is solved the problem with the forces between molecules of the resin on the one hand and the build plate/cured resin/on the other. Science knows only one method, but in the Carbon I do not see it. If implemented it, the printer will not work.If Carbon works as advertised will...
