    • Applications of 3D Printing Dr. Ben Wood & Dr. Greg Gibbons© 2012
    • A couple of questions to start… WHO USES 3D PRINTING? WHAT FOR?© 2012
    • Architecture© 2012
    • Marketing/Advertising© 2012
    • Medical© 2012
    • Furniture© 2012
    • Fashion© 2012
    • Animation© 2012
    • SME Application • Injection mould tool ~£10,000 – Requires high volume – Difficult to modify – Tool required for each product • Insert tooling – Simpler pocket tool required – 3D printed insert – Lifetime of 10-200 parts – Low insert cost – Easy to modify/replace© 2012
    • IIPSI 3D Printing Capabilities and R&D Dr. Greg Gibbons© 2012
    • 3D Printing • Significant capability in commercial 3D Printing technology – FDM • MJM • 400mc (Stratasys) – Connex 260 (Objet) • Dimension (Stratasys) • Laser Sintering • Prusa (RapRep) – EOS P380i – 3DP • EBM • Z450 (ZCorp) – Arcam S12T • Z310+ (Zcorp)© 2012
    • FDM (Fused Deposition Modelling) • 400mc – Wide range of materials • Thermoplastics • High temperature • High impact – Have in-house facility to manufacture bespoke feedstock • Xtrutech twin-screw extruder • Novel material capability • Metal, ceramic filled - sensors and actuators a possibility© 2012
    • FDM (Fused Deposition Modelling) • Prusa RepRap – Lowest cost 3D Printing system available – Range of low-cost thermoplastics – Initial test-bed for novel materials – Evaluating system for appropriate applications© 2012
    • 3DP (3D Printing) • Z450 – Enables full colour printing of working assemblies – Upgraded to ZP150 (stronger and whiter, more vivid colours) • Z310+ – Mono printer – Utilised for materials and applications research© 2012
    • MJM (Multi-Jet Modelling) • Connex 260 – Multi-material printing – 10 variations in material properties in one build • Stiffness variation • Density variation • Colour variation • Transparency variation – Potential for research • Novel material combinations • Offering new product capability© 2012
    • LS (Laser Sintering) • P380i – Range of functional thermoplastics • Polyamide 12 • Aluminium / polyamide 12 • Carbon fibre / polyamide 12 • Polyamide 11/12 co-polymer – Polystyrene • Supports direct manufacture of complex investment cores – Potential for research • New materials • New applications© 2012
    • 3DPrinting Research Activities • In addition, WMG has significant 3DP research activity, supported by a number of technologies – Metallic and metal – Polymeric / composite 3DP composite 3DP • High resolution hybrid polymer / composite • High resolution laser deposition melting • High resolution 3D • Electron beam melting Photocopying • Plasma Transferred Arc / • Medical modelling CNC • Low cost 3DP© 2012
    • Plasma Transferred Arc / CNC • Hybrid system utilising PTA to deposit metals and alloys, with CNC material removal – 2 powder feeds – 1 wire feed – CNC machine between layers • Advantages – Repair and augmentation of parts – Functionalise parts – Hybridise parts© 2012
