At the Additive Manufacturing Users Group (AMUG) conference underway this week in Chicago, 3D printing company Nexa3D launched a new printer, the NXE 200. According to the company, the NXE 200 is an ultrafast, industrial-grade 3D printer for applications including functional prototypes, production manufacturing, engineering builds, and jigs and fixtures.

The NXE 200 printer has a build volume of 8.5 liters and a build area of 275 x 155 x 200mm. It is compatible with Nexa3D’s variety of resin materials and the company’s xWash and xCure post-processing technology, as well as its NexaX 2.0 printing software.

The printer is priced at $49,990 including installation. Until the end of May, this price will also bundle an xCure curing unit and NexaX 2.0 software.

What Sets the NXE 200 Apart?

The NXE 200 uses Nexa3D’s Lubricant Sublayer Photo-curing (LSPc) printing process, a type of resin 3D printing which the company claims is both faster and more accurate than the closely-related digital light processing (DLP). The NXE 200 prints at 6.5 times the speed of other resin 3D printers, according to a press release issued by Nexa3D.

This speedup is enabled in part due to Nexa3D’s Everlast-2 membrane, a self-lubricated interface between the resin and the structured light matrix that Nexa3D claims “overcomes the delamination forces that accrue during any inverted, vat based printing process, enabling ultrafast printing speed.” The membrane lasts a minimum of 50,000 printed layers—25 times longer than alternative interface technologies, according to Nexa3D.

The NXE 200 is equipped with a high-resolution 4K LCD light engine and Nexa3D’s LSPc high contrast mask, a combination which the company claims eliminates a common issue in DLP printers: light diffusion near part edges. Nexa3D says this adds up to exceptional part accuracy, surface finish, and mechanical properties.

“Consumers should not have to accept tradeoffs between quality and affordability,” said Michele Marchesan, Nexa3D chief revenue officer for industrial products, in the company’s press release. “The NXE 200 offers extremely high productivity, in addition to superior accuracy, aesthetics, and mechanical properties, at the lowest total cost of ownership.”
