Lunavast XG2 DLP 3D Printer Kit

A projector with native XGA (1024 x 768 pixels) resolution and a normal lamp (NOT LED) is required separately. I purchased a broken one at US$30 at eBay like auction site. The color wheel was broken but it is not used for DLP 3D printing :)

With 0.1mm X-Y resolution, the size of normal build area is 102.4mm x 76.8mm.
Because of XG2's original sliding VAT and Stage mechanism, it can double the build area to 102.4mm x 153.6mm with future software update. (Z height is more than 100mm)

No modification is required for the projector. So, you can still use it to show movies or data from PC. The universal projector holder frame design can fix any type of projectors.

Specifications:

Build area: 102.4mm x 76.8mm (Normal mode) or 102.4mm x 153.6mm (X2 mode)
Resolution: X-Y 0.1mm Z 0.1mm
Printing speed: Fast printing speed (Still testing)
