The Admetalflex 130 by Admatec is a metal 3D printer that uses Direct Light Processing (DLP) technologies, a technique similar to stereolithography. This is not a commonly used technology for 3D printing metal, usually used in rapid prototyping plastic models.
The Admetalflex 130 has a print volume of 96 x 54 x 120mm before sintering, and is compatible with aluminium oxide, zirconium oxide, and silicon dioxide. It weighs approximately 300kg and prints around 20-25mm per hour.
