Insight Podcast: DMLS Q&A Part 2

Written by: Protolabs | Published: 10/21

​In this episode we answer your questions on DMLS with Tasos Pantelis, an Application Engineer at Protolabs and our 3D Champion for Europe. See below for a list of questions answered in this session:

  • In general, where is a break even point between this process and standard machine items, in reference to the number of items produced?
  • How much does the resolution setting effect component price?
  • What is the maximum size/mass that can currently be made?
  • What level of porosity is present in a DMLS part? are secondary operations required to achieve pressure tightness?
  • Cost wise, how does the cost of DMLS compare to other rapid prototype methods such as SLA/SLS? is there a part size limit?
  • Can a single part be printed with 2 or more materials in one go?
  • I see that you are ISO-13485 certified for medical implants with a choice of two biocompatible materials. Is there any specific process you use for them to ensure biocompatibility?
  • Where does post-machining come in on DMLS? Can you polish parts? How do you ensure consistency as well as accuracy?
  • Are there methods to improve the finish during manufacture, for example, for internal curves and volumes?
  • What advantages and disadvantages are there regarding DMLS, and a comparison to other methods such as EBM?
  • Do you employ post-printing manufacturing methods to improve the properties of DMLS made components? For example, chemical etching, hot isostatic pressing (HIP), electroplating.
  • What are the main challenges you see with 3D printing metals today, and the work being done at a company like Protolabs to overcome these challenges?
