Presentation Highlights LENS Production Grade 3D Printing Technologies for Structural Metals

Albuquerque, New Mexico. March 11, 2015: Optomec announced today that the Company featured its LENS 3D Metal Printers at the 7th annual Laser Additive Manufacturing (LAM) workshop in Florida last week. Optomec LENS 3D Metal Printing systems are used to cost-effectively repair, rework and manufacture high-performance metal components in materials such as titanium, stainless steel, and superalloys. The LENS Print Engine, which is a modularized version of the LENS 3D Printing system for metals, was also featured at the conference. The Print Engine can be integrated with standard metal cutting machine tools to cost effectively deploy Additive Manufacturing as part of existing production infrastructures.

In addition to the exhibit, Dr. Richard Grylls, LENS General Manager, gave a presentation titled “Laser Material Deposition in a Controlled Atmosphere”. Dr. Grylls’ presentation explained how LENS systems use a high-power laser (500W to 4kW) to fuse powdered metals into fully dense three-dimensional structures. The LENS process can be housed in a hermetically-sealed chamber which is purged with argon so that the oxygen and moisture levels stay below 10 parts per million. This keeps the part clean, preventing oxidation. The metal powder feedstock is delivered to the material deposition head by Optomec proprietary powder-feed system, which is able to precisely regulate mass flow. Once a single layer has been deposited, the material deposition head moves on to the next layer guided by a tool path created from a CAD model or scanner. By building up successive layers, the whole part is constructed. When complete, the component is removed and can be heat-treated, Hot-Isostatic-Pressed, machined, or finished in any customary manner.

The Laser Institute of America’s (LIA’s) 7th annual Laser Additive Manufacturing (LAM) Workshop brings together representatives from industries including power generation, aerospace, agriculture and automotive. The workshop draws dozens of experts from around the world to discuss not only traditional laser-based techniques like cladding but the revolutionary applications of Additive Manufacturing in medicine and dentistry, the aviation and automotive industries, and even consumer products.
