Direct Metal Laser Sintering (DMLS) is an additive laser melting technology that can be used for manufacturing functional metal components and tools in various alloys including light metal alloys, high grade steels, stainless steels and super alloys – both nickel and cobalt chrome based.
This presentation will review the latest results of the materials development work done with EOSINT M270 laser sintering machine. The main topic of the presentation will be in heat resistant nickel alloys but a short status update will be given also on other available DMLS-materials.
Several DMLS-processed nickel alloys have been investigated and characterized in the recent years. EOS NickelAlloy IN718 (UNS N07718) and IN625 (UNS N06625) have been the first ones developed and optimised for the DMLS-process. Material characterization and testing has proven that properties of these laser processed alloys are close to the wrought specifications of similar alloys. The microstructure quality, soundness and special characteristic of the laser processed alloys will be discussed.
These current generation DMLS-materials, EOS NickelAlloy IN625 and IN718, will show the potential and the viability of the technology in aerospace applications in the near future. It is possible that modern nickel superalloys, which have even higher temperature resistance and other improved characteristics, will open even more possibilities for this technology in the coming years.
