Wisconsin-based 3D printing company Micronics has announced its new Micron desktop Selective Laser Sintering (SLS) 3D printer.

Priced at $2999, the Micron is designed to bring industrial-grade 3D printing capabilities to desktops for professionals and hobbyists alike, says the company. One of the key features of the Micron is its ability to print complex objects without the need for support structures. This is achieved through a high-powered laser that fuses layers of powdered plastic together. The surrounding unfused powder acts as a natural support for the object being printed, allowing for the creation of intricate shapes with a high degree of accuracy.

Design freedom and durable materials

According to the company, the printer focuses on producing high-quality, durable parts. It utilizes high-performance polymers like Nylon, resulting in parts that are reportedly very strong and resistant to chemicals and wear. Additionally, the build chamber allows users to maximize efficiency by stacking hundreds of parts for production runs.

Safety and user-friendliness are key aspects of the Micron’s design. The printer includes MicroSlicer, a complimentary, custom-built software program designed specifically for the Micron. This software features a novel physics-based packing algorithm to optimize part placement within the build chamber. The printer itself features a fully enclosed powder handling system for clean operation and built-in safety features, including 2-stage carbon-HEPA filters and a removable fume extractor.

Another noteworthy aspect of the Micron is that it is entirely built and supported in the USA. This ensures high quality and reliability for users. To further protect user privacy, both the printer and the slicer operate completely offline.
