The LENS MR-7 system offers a 300mm cubed work envelope, making it ideal for the manufacture, repair and addition to smaller components. LENS systems use energy from a Fibre Laser to build up structures one layer at a time directly from powder – metals, alloys, ceramics or composites. Up to four powder feeders allow gradient materials to be made – every layer can have a different chemistry. This enables new materials to be made and analysed with extraordinary speed. LENS systems are used throughout the entire product lifecycle for applications ranging from rapid alloy development and functional prototyping to rapid manufacturing or repair.

LENS systems builds fully dense structures directly from a 3-dimensional CAD solid model. The CAD model is automatically sliced into a tool-path, which instructs the LENS machine how to build the part. The part is constructed layer by layer under the control of software that monitors a variety of parameters to ensure geometric and mechanical integrity. The LENS process is housed in a chamber which is purged with argon such that the oxygen level stays below 10 parts per million to ensure there is no impurity pick-up during deposition. The metal powder is fed to the process by Optomec’s proprietary powder-feed system, which is able to flow small quantities of powder very precisely. When complete, the part is removed and can be heat-treated, hot-Isostatic-pressed, machined or finished in any other manner.
