Investor Presentaiton

LPBF shows superior properties vs. MBJ Better quality, material range and geometric freedom Laser Power Bed Fusion (LPBF) VS. Metal Binder Jetting (MBJ) SLM SOLUTIONS ☐ High mechanical properties and extreme accuracy High density and low porosity Quality Wide range of materials ■ Size only constrained by machine chamber size, suited for a wide range of thickness ☐ Controlled part shrinkage and part distortion possible Solid metal parts are produced directly, in a single process Source: AM Power, SLM Printing Post- Processing, Lower mechanical properties, lower density and higher porosity vs. LPBF Complex sintering process with many unknown effects and low first-time-right availability Material range Currently, material choice limited Geometric freedom Productivity ☐ ■ Limited size and minimum thickness of parts Shape limitations due to debinding and sintering Uncontrolled creep deformation possible Multi-step process - solid metal parts are only created during last step of sintering Build-up rate significantly lowered by shrinkage - debinding and sintering required to turn "green part” into metal part Printing Debinding Sintering 20
