Desktop 3D printers are immensely useful in a machine shop, but can emit volatile organic compounds (VOCs) and ultrafine particles (UFPs) that are harmful to humans. Here are some guidelines to install and operate them safely. When I began reporting on additive manufacturing (AM) just five years ago, I quickly learned about the dangers of metal 3D printing, from the combustible materials to the risks from inert gas leakages. Working with powdered metal is no joke, which is why operators are often pictured in full PPE including respirator, fire-resistant jacket and nitrile gloves. If you ask one of these folks about safety, they’ll likely point out facility features like specialized fire extinguishers, spark-resistant flooring and air quality monitoring systems. There’s a considerable ...

The BMW Group has opened a new €15 million additive manufacturing facility which is designed to “industrialize 3D printing,” and shorten production times across the company.  Based in Munich, the campus will bring BMW’s prototype production, series parts manufacturing, research into new 3D printing technologies, and training, together under one roof. The centre will also house around 50 percent of the automotive company’s global additive manufacturing (AM) capacity, comprising 50 industrial polymer and metal 3D printers. By centralising its 3D printing resources, BMW aims to acc...

Martensitic steels are some of the strongest, least expensive and most lightweight forms of these types of metals. However, until recently, working with this metal has been a complex manufacturing process only used by certain industries.

Selective LED-based melting (SLEDM) -- i.e. the targeted melting of metal powder using high-power LED light sources -- is the name of the new technology that a team led by Franz Haas, head of the Institute of Production Engineering at TU Graz, has developed for 3D metal printing and has now applied for a patent. The technology is similar to selective laser melting (SLM) and electron beam melting (EBM), in which metal powder is melted by means of a laser or electron beam and built up into a component layer by layer. However, SLEDM solves two central problems of these powder bed-based manufactur...
