PMMA 500 x 400 x 300 VX200 PSB, PMMA type C 300 x 200 x

5 Systems: Our 3D Printer Platforms We offer a range of build box sizes and material sets to match our customers needs. SYSTEM MATERIAL SET BUILD BOX SIZE (LxWxH mm) VX4000 Sand 4,000 x 2,000 x 1,000* VX2000 PDB 2,000 x 1,000 x 1,000 VX1000 PDB, PMMA 1,000 x 600 x 500 VX500 PDB, PMMA 500 x 400 x 300 VX200 PSB, PMMA type C 300 x 200 x 150 * build space depending on height ** depending on material set and layer thickness voxeljet AG, Friedberg 5

6 Materials to Meet Customer Needs PARTICULATE MATERIALS Sand Silica Kerphalit Plastic PMMA (acrylic glass) BINDING AGENTS Furane (Services only) Phenolic Resins Polypor B Polypor C voxeljet AG, Friedberg 6

7 Our Technology Saves Time and Money TRADITIONAL METAL CASTING PROCESS Pre-processing CAD Design Pattern production Mold Cast Part Weeks WITH OUR TECHNOLOGY CAD Design Pre-processing Mold Cast Part > 50 % time savings Flexibility to alter design real-time Ultimately delivers cost savings Days not Weeks 0 Days 5 voxeljet AG, Friedberg 7

8 Applications Automotive & Aerospace Engineering & Design Art & Architecture Film & Entertainment Investment Casting Patterns: Spare parts, Additive Manufacturing, Art Sand molds & cores: Prototyping, Design/Customization, Mockups/Props voxeljet AG, Friedberg 8

reduction Stock reduction Design for Manufacturing (gating, pressure etc.

9 Casting Why use 3D printing for sand and investment casting? Part reduction complex consolidated cores & molds Drawing reduction Tooling reduction Stock reduction Design for Manufacturing (gating, pressure etc.) Proof of design in tool manufacturing Less assembly effort, time & costs voxeljet AG, Friedberg 9

10 Casting simulation voxeljet AG, Friedberg 10

11 Casting simulation Right-1st-Time-Castings vs. Trial and Error Remove material, maintain functionality Design ONE complex consolidated part Add structure to internal sections End product features End product functionality Improving component life Saving costs on obsolete components voxeljet AG, Friedberg 11

12 The freedom of 3D-Design Runners, ingates and feeders / risers customized: Round Position Shape Gate speeds Pressure voxeljet AG, Friedberg 12

13 PMMA applications Investment casting Preparation with wax rods Shell building Burnout of PMMA Aluminium casting Shell cracking Finished castings voxeljet AG, Friedberg 13

14 Casting investment casting Printed PMMA parts including printed runner system voxeljet AG, Friedberg 14

15 Casting Sand casting 1. CAD File 2. Sand Mold 3. Integrated Gating System 4. Embedding the Sand Mold 5. Aluminium Pouring 6. Solidification 7. Demolding 8. Cooling 9. Lost Sand Mold 10. Casting Including Gating System 11. Finished Casting 12. Casting with Sand Mold voxeljet AG, Friedberg 15

16 Casting Sand casting Different approaches a) Printed moulds and cores b) Hybrid production: Combine printed cores with traditional moulds c) Integrate cores into moulds d) Casting (press) toolings voxeljet AG, Friedberg 16

17 Casting Sand casting a) Entirely printed mould and core set voxeljet AG, Friedberg 17

18 Casting Sand casting Entirely printed mould and core set voxeljet AG, Friedberg 18 Folie 18

19 Casting Sand casting b) Hybrid production Combine printed cores with traditional moulds Simplify complex cores / reduce number of cores water jacket core Impeller core voxeljet AG, Friedberg 19

20 New applications lamination Sand mould infiltrated with epoxy resin, polished and varnished with a release agent Laminated carbon fibre with processed sand mould voxeljet AG, Friedberg 20

21 New applications concrete casting Sand mould printed with silica sand, infiltrated with concrete wash Type A Removing the sand mould from the cast concrete facade voxeljet AG, Friedberg 21

22 Benefits of voxeljet s technology GENERAL Time savings due to very fast build process Usual foundry materials Largest build volumes on market Complete freedom of design Design changes can be implemented immediately Partner network: rapid production of finished cast parts Cost-effective SAND Molds up to 4 x 2 x 1 m in one piece 300 µm silica sand layers No need for expensive mold set-ups PMMA 100 % reusable powder No supports needed Castability like wax patterns voxeljet AG, Friedberg 22
