68 MMS September 2017 mmsonline.com ADDITIVE INSIGHTS Understanding Industrial 3D Printing post-process machining and finishing. This is because, in addition to being dangerous if inhaled, some metallic powder feedstocks like titanium and aluminum are pyrophoric, which means they can explode. So machining profes- sionals need to be careful when finishing parts built from these materials; trapped powder may be released into the machine environment, and a spark or other combination of conditions could lead to an explosion. Extra caution should be used in handling and postprocessing these parts, first making sure that they have been properly cleaned. If any loose powder falls when the part is handled, it is not ready for machining. During machining, using ample lubricant will help carry away loose powder and minimize the risk of inhalation or sparking. Shops may want to also install high-end filters on their machining centers to help capture these particle, as they are a lot smaller than the metal chips and pieces that are usually filtered out of the used lubricant stream.

It behooves us to talk to related industries that routinely use powder metal feedstock in their manufacturing processes to see how they handle and safely work with these materials. In the meantime, AM users need to know what material is being handled, take extra care to make sure that loose powder has been cleaned from parts before machining and make sure to use plenty of lubricant during machining. The last thing we need is for an AM part to explode on a mill or lathe as it is being finished; that would not be good for the operator, the company or the AM industry. So, be careful! OPM250L Metal 3D Printer The Sodick OPM Metal 3D Printer was built to do what no previous 3D printer could. Sintering at a 99.99% density, OPM-made parts are among the strongest on the market. And with a 40,000 rpm spindle, the OPM finishes parts up to 9 RMS surface finish and beyond.
