Laser Powder Bed Fusion (LPBF) Sole AM technology with widespread industrial use Superior mechanical properties... Size / Geometric Freedom SLM SOLUTIONS ...make LPBF the leading AM technology in the market today and tomorrow ■ Size of parts only limited by machine chamber size Outperforming in terms of absolute size and variability of part thickness ☐ Geometry complexity is for free, allowing for topology optimization that is without limits Constantly high mechanical properties Mechanical Low porosity Properties High density Wide Material Choice Compared to all other additive technologies LPBF offering greatest number of input materials. Any material that can be welded can be processed technology 20211) Investment related to Installed base (units) by AM in next years²) Other 5 (Laser) Powder Bed Fusion 84% 1% Binder Jet 3% Metal FDM 6% Direct Energy Deposition 7% Industrialization Index 4 3 Metal AM Maturity Index 2022 Wire Laser Beam ED L-PBF Widespread industrial use Time until industrial use • Index reached Less than 2 years ● 2 to 5 years More than 5 years Wire Electric Arc ED- Metal Filament ME Coldspray Friction Energy Deposition- Nanoparticle Jetting Ultrasonic Energy Deposition Area-wise L-PBF Metal Lithography E-PBF Powder Laser Beam ED Wire Plasma Arc ED Binder Jetting Metal Pellet ME 6 Hybrid Binder Jetting Metal SLS Mold Slurry Deposition Liquid Metal Printing Industrial use First applications Prototype system Proof of AMPOWER concept Source: addive-manufactur-report.com Copyright 2022 Ampower GmbH & Co.
