"I know this is a somewhat older post but I actually used this a lot to help explain the differences to people. So, thanks!To help add some clarity to it all we just released an overview of all 3D printing technologies here: 3dhu.bs/AMTech (sorry for the plug, but I truly believe it's a useful reference so figured I'd share). Although you're correct in your article about the difference between DMLS and SLM, I decided to merge them nonetheless as the differences are patent and trademark related and don't reflect in applications that much. Thus, all the same for the user.Curious about your thoughts on the decision.Cheers!Filemon"
