Re: laser projector
Hello Max. I have been experimenting with a Benq laser projector and so far the results have been far from satisfactory. In order to minimize modifying the projector, I started by purchasing some blue light curing resin from Bucktown polymers. I removed the color wheel to obtain as much blue light a...

Re: FEP vat challenge

Re: Top-down air pocket design?
Great idea! Then you can fill the pocket with low pressure oxygen and create a dead zone, made of resin that won't harden when exposed to UV light, focus your beam right under the surface and you'll have a continuous printing machine.

Loving my top-down setup.
It seems like my top-down machine is complete and ready for printing lots of parts. It is equipped with a wiper system, but I've noticed that if you give the resin enough time to settle you'll get great results. The bracelet was printed with Makerjuice floating resin. Z resolution was setup at 30 mi...
