Optomec LENS MR-7 review

The Optomec LENS MR-7 is an industrial 3D printer made by Optomec, a manufacturer based in Albuquerque, USA.

Optomec LENS MR-7 3D printing technology

The Optomec LENS MR-7 uses LENS 3D printing technology to build metal parts. The LENS based 3D printers use a high-power laser (500W to 4kW) to fuse powdered metals into fully dense three-dimensional structures.

The LENS process takes place in a closed 3D printing build chamber which is purged with argon so that the oxygen and moisture levels stay very low (<10 ppm). This keeps the part clean and prevents oxidation. The metal powder feedstock is delivered to the material deposition head by Optomec’s proprietary powder-feed system. Once a single layer has been deposited, the material deposition head moves on to the next layer. This process is repeated until the whole part is constructed. When complete, the component is removed and can be heat-treated, hot-isostatic-pressed, machined, or finished to best suit the final application.
