After previews earlier in the year at CES 2017, Taiwanese 3D technology developer XYZprinting has released the Nobel Superfine 3D printer. This latest machine using digital light processing (DLP) technology focuses on delivering high resolution, a wide range of materials, compact housing and high processing speed.
High resolution resin printing
DLP technology is different to stereolithography (SLA) printers in that it uses UV light instead of laser technology to selectively harden resin. The UV light is digitally projected from a screen beneath the build plate and flashes a single image of each layer across the resin-filled build platform. A peeling process, whereby the uncured resin is tipped to one side, prepares the next layer for curing.
XYZprinting’s DLP technology is now able to produce layers “three times thinner than a strand of a human hair” which is typically 50 microns in diameter.
It is able to print layers along the Z axis at a resolution up to 25 microns, and X and Y up to 50 microns. With these dimensions, the Nobel’s superfine has a sharper resolution than XYZprinting’s existing machines.
Multifunctional to multicoloured
The resin used to print jewellery and dental fixtures is vastly different. While both must be easy to to imprint details on, the latter must be biocompatible and resistant to erosion and breakage.
Compatible with XYZ’s photopolymer and castable resins the Nobel Superfine is able to produce both.
XYZ have also recently released the da Vinci Color, dubbed “the world’s first CMYK full-colour desktop 3D printer”. Both systems are on display at this week’s TCT Show.
