The Structo OrthoForm is a professional 3D printer made by Structo, a company based in Singapore.

The Structo OrthoForm is a 3D printer with a closed frame designed for dental applications. This 3D printer uses a patented Liquid Crystal Mask Stereolithography (MSLA) 3D printing technology, a process similar to Stereolithography (SLA), where layers of liquid resin are photopolymerized.

MSLA Structo’s 3D printing technology uses a panel light source array and a liquid crystal film mask (hence the name) to control which regions of the printing plane are illuminated by the light source. Therefore., the main difference between Digital Light Processing (DLP) based 3D printers and the MSLA technology is the number of individual emitters, hundreds for MSLA, while DLP relies on a single point emitter light source (laser diode or DLP bulb).

This orthodontic 3D printer can 3D print up to 28 dental model arches in less than 2 hours. The building speed of the Structo OrthoForm is 18 cm3 / minute.
