Re: Open source LCD resin printer

Still I have not a good quality printing. The reasons were in the z axis, in the resin / forgot to mix it / and in the vat. The main is that the vat is directly on the display and have no distance. I hope today to have a success if I have enough time.

Re: Open source LCD resin printer

thank you hp_
Forget everything you know about the LCD printers! The LED array and the drivers cost about $ 200. I think it's very cheap

Re: Piezo ultrasonic release

I tried but without any success. The problem is in the vacuum, not in the sticking. In theory this works but not in practice.

Re: Daylight Polymer 3D Printer

With a UV sensitive resin
I think it's too early for Daylight Resin. For a cheap and slow printer is OK, but if you want to be fast, the price will be the same regardless of the polymer.
