The Lunavast XG2 is a kit to build a resin-based personal 3D printer. The XG2 uses DLP technology to project a pattern onto the surface of a vat of resin to progressively solidify each layer. The XG2 kit does not include the critical DLP projector, which can easily be obtained almost anywhere at low cost. You can even use a DLP projector that has a broken color wheel, since the XG2 requires no colors for its light pattern.
The XY resolution of the XG2 is 1024 x 768, also known as standard XGA resolution. On the Z-axis, the XG2 produces layers of 0.1mm thickness, all within a build chamber volume of 102.4 x 76.8mm. Evidently a software update will enhance the build size to 102.4 x 153.6mm sometime in the future.
While their speed testing is still underway, the XG2 is a resin 3D printer, which are typically faster than traditional plastic extrusion 3D printers. Why? Because resin-based 3D printers can create an entire layer in a single operation, whereas plastic extruders must laboriously trace out all solid portions of each layer.
The software that drives this device is entirely open source, including Slic3r and Printrun.
Lunavast will sell you an XG2 for USD$980 right now (well, with a 4 week delivery delay) and they’ll also sell you 1kg of resin for USD$139. Oh, and shipping, which is significant: USD$75 to Asia, but USD$102.50 to North America and Australia. Europe is USD$117 and those in Africa and South America will pay USD$200 for shipping. The price of the kit, shipping and a used DLP to get this running could run you in excess of USD$1200 in some cases.We haven’t heard from Lunavast before, but it’s pretty clear they are new. Visiting their “About Us” and “Customer Service” pages yields a default “Lorem ipsum dolor sit amet…” from their Magneto eCommerce installation. They seem to accept only PayPal at this time, but we could not verify so. We were unable to successfully get through the payment process during while testing a purchase. You might want to wait and see how they proceed.
