Nexa3D needs your cash to make its 'ultrafast' 3D printer

23.11.2015 | Engadget | www.engadget.com

Company called Nexa3D has launched a product on Kickstarter, claiming that you'll be able to print objects at a speed of around 1-inch every 3 minutes. That's around 25-100 times faster than a regular 3D printer, and objects can be made to around 120 microns of detail, fairly close to the resolution of a Makerbot Replicator 2.

This new system works by using light to harden a photo-curing resin that is gradually extruded from a tank. The Nexa3D works with "self-lubricant sublayer photocuring (LSPc)" tech, that uses a layer of oil to prevent newly formed layers from sticking to the build platform. If the object size becomes large enough, then the printer switches from continuous extrusion to a sequential system that deposits the resin in layers, like a conventional 3D printer.

Nexa3D says it has also greatly simplified the printing process with its resin cartridge system. Rather than needing to refill tanks or reels like a regular "PLA" printer, you just insert the cartridge and print. The system automatically fills the tank, then recaptures any unused resin for the next job. There's also a cleaning cartridge that will scrub the resin tank clean if your next job uses a new color.
