4 Using Additive Manufacturing technology, three-dimensional solid objects of virtually any shape can be made from digital data Definition and advantages Definition > Additive Manufacturing (AM) is a process of making a three-dimensional solid object of virtually any shape from a digital model > AM uses an additive process, where materials are applied in successive layers > AM has a 26-year history for plastic objects the capacity to make metal objects relevant to the engineered products and high tech industries has been around since 1995 Key advantages > Direct production from CAD data > Freedom of design > Complexity for free > Part consolidation > Elimination of tooling > Max. material use > Production cost independent from batch size > New manufacturing processes, e.g. in repair, and materials Source: Roland Berger 4

5 Powder bed fusion is the most frequently used technique for printing metal objects Powder bed fusion (PBF) Laser system Powder coater Scanner system Loose powder Build plate PROCESS STEPS AND COMMENTS > Powder bed fusion (PBF) is the accepted ASTM 1) term for an additive manufacturing process where a point heat source selectively fuses or melts a region of a powder bed. The process is also known as direct metal laser sintering (DMLS) or selective laser melting (SLM) > PBF is the most frequently used technique: Powder is dispensed Parts are selectively melted via laser Build station is lowered and new powder is dispensed > PBF systems use either a laser beam (very often) or an electron beam (rarely) to melt regions of a powder bed > Electron beam PBF enables higher build rates, but surface quality and choice of materials are more limited Build station piston SLM 250, 1:40 1) American Society for Testing and Materials (ASTM), Source: Roland Berger 5

6 From today's point of view the "paths of disruption" only have a minor impact on production This will change in the future! Paths of disruption for Additive Manufacturing Direct production from CAD data Freedom of design Complexity for free Part consolidation Elimination of tooling Prod. cost independent from batch size New manufacturing processes Path of disruption Examples Limited impact Source: EOS, Roland Berger, NASA Individual products > Prototyping > Mass customization Medical products Jewelry Gimmicks > Small series production Strong impact New geometries & materials > Integration of new, enhanced functionalities (more efficient products) in high tech materials > Development of new materials/material properties > New repair strategies New business models (B2B, B2C ) Decentralized production > Industrial production on demand production by quantity by location (decentralized) > Home printing/production > Outsourcing to partners 6

27 Current AM systems utilize multiple lasers to increase productivity and reduce manufacturing time Multi-laser concept The current state-of-the-art solution Principle Realization > AM production time depends on the layer-by-layer laser exposure time, lowering of the chamber platform and powderbed distribution time > Using multiple independent lasers, different areas can be manufactured in parallel with direct impact on exposure time E.g. dual-laser systems halve the exposure time leading to an overall productivity increase by a factor of 1.8 # of laser spots Commercial systems available with up to 4 laser systems Time Image of the manufacturing chamber of SLM Solution's SLM 500 HL system capable of using 4 independent lasers and scanner systems simultaneously Result > A higher number of laser spots yields a direct increase in manufacturing speed > Nevertheless, multi-laser technology faces some problems, e.g.: The laser system is the system's most complex and expensive component Heat and fume creation scales with the number of laser spots and limits the manufacturing process > Limited advantage of multi-laser technology: scaling of the system with the most complex and expensive component fundamentally limits the method's cost advantage Source: SLM Solutions; Roland Berger 27
