NLC's host of new laser additive-manufacturing technologies

"The LENS 3D printer uses the geometric information contained in a computer- aided design solid model to automatically drive the process, as it builds a component layer by layer," Sciammarella says, adding that additional software and closed-loop process controls ensure the geometric and mechanical integrity of the completed part. The process is housed in a hermetically sealed chamber, which "keeps the part clean, preventing oxidation," Sciammarella says. Engineering News reports that the system can also be used to refurbish or repair old parts. Newer materials can be used on old parts, making them last longer.
