1 Micro Laser-Sintering by 3D MicroPrint GmbH

2 3D MicroPrint GmbH at a glance Q3/2014 3D-Micromac and EOS cooperate in Micro Laser Sintering (MLS) MLS technology demonstrator available MLS application development with Industry New Machine generation sold to TU Darmstadt First production facility in place established

3 3D MicroPrint GmbH at a glance Founded in June 2013 by 3D-Micromac AG and EOS GmbH Equipped with Staff: > 7 years Micro Laser-Sintering Know how: Additive Manufacturing, Precision Engineering IP: portfolio of patents & licenses Contact 3D MicroPrint GmbH, Technologie-Campus 1, Chemnitz, Germany info@3dmicroprint.com

4 Motivation: Market Challenges Time to market Focus on Sustainability Customization Additive Technologies address these market challenges Flexibility Cost and productivity pressure, Cost-Per-Part Differentiation by customer value add

5 Technology Functional Principle Micro Laser Sintering

6 Advantages of additive Technologies Freedom of design Lightweight Static: weight of parts Dynamic: moving, accelerated parts Lattice structures without extra cost Lattice structure Cost advantages Integrated functionality Embedded functionality without assembly Minimized stock Minimized QA No assembly Grabber Customization Individualized parts Customer specific adaptations Medical implants Jewelry Time to market Organization Prototyping and Serial applications Fast feasibility feedback CAD data to parts Cost efficient small series Just print it

7 Technology This area is secure because of the gas tight Machine, Workstation and the Rapid Transfer Port QA Part & Tool cleaning Post processing MLS machine Powder Platforms Tools Parts Warehouse Workstation Sieving Preparing Cartridges Powder Platforms Tools

8 Hollow rook Challenge A lot of small details Standing alone objects Hollow structure Solution build by MLS Post process by polishing Image source: 3D-Micromac, EOS

9 Frauenkirche Dresden Challenge A lot of small details Standing alone objects Hollow structure Solution build by MLS Post process by polishing Image source: 3D-Micromac, EOS

10 Flexible ring Challenge Movable parts Without assembly Hollow structure Solution build by MLS Post process by polishing Image source: 3D-Micromac, EOS

11 Applications Flexure hinge arm design Grabber details Micro Grabber Challenge For handling applications, a flexible yet strong arm with a mounted grabber is required Solution Flexure hinge designed for optimal mechanical response Hinges with 300 µm gap width Advantages Functional integration: hinges are integrated in the main body Miniaturization of grabber mechanics Grabber head manufactured in one piece

12 Applications 90 µm 45 µm 32µm Square holes & lattice structures Challenge Radiation applications from medical devices to space research need structures to guide or shield radiation Solution Square holes and even changing cross sections just do it Wall thickness down to 15 µm imaginable today Advantages MLS enables certain solutions for the first time Lattice structures, a few micron thick can be manufactured much cheaper with MLS than with e.g. etching

13 Applications Fluid mixing chamber Challenge Mixing solution required for 3 liquid components; applied mechanical load has to be minimized Solution Spiral shaped pipes with 200µm wall thickness and 150µm inner diameter Advantages Applied load is minimized, no moving parts required for mixing mixing ratio can be easily modified by pipe diameter, flow ratio and design of the mixing chamber

14 Product Portfolio Consultation & solution development Machines and complete solutions Feasibility study Series production of metal micro parts
