2. 2 What is 3D printing?  What is 3D printing?  Processes | Material Choice | Different systems  Collecting Data  White Light Scanning | MRI/CT/Ultrasound  Why use 3D printing?  Additive manufacture v’s subtractive | fabrication | formative.  Key drivers  Economic, Environment, Design  Limitations of 3D Printing

3. 3 3D printing  History – 1984 in California – 3D Systems (worth $2 billion)  Process – the process of taking 3D digital data and creating a tangible object through additive processes utilising a layering technique.  Current systems - SLA, SLS, FDM, MJP, LOM  Materials OrganicCeramicPolymericMetallic Waxes Tissue/cell Sugars Sand Plaster Silicon carbide Plaster ABS Nylon PEEK AU Loaded polyamide Aluminium Steel Titanium

17. 17 Why use 3D printing?  Additive manufacturing process  Drivers – economic, environment, design freedom  No need for tooling, jigs and fixtures  Reduced capital investment (e.g. injection moulding)  Simplified supply chain – reduces lead time

18. 18 Why use 3D printing?  Embedding materials – electronic encapsulation  Geometric freedom – example : lattice structure developed for crumple zone on vehicles  Bespoke products – example: bio-medical applications, hearing aids, implants & replacements

19. 19  Life cycle and sustainability  reduces raw material, lighter weight components – example: honeycomb structure for aerospace industry saves fuel.  Reduced energy over traditional processes – AM produces ¼ of CO2 emissions compared to CNC  Scalable – example: “Contour Crafting” buildings Why use 3D printing?

20. 20  Contamination of materials  Consistency of machines  Controlling production environment  Reliability  Low volume high cost products  Econolyst assessed over 200+ products in last 7 years – 90% are not suitable Limitations & Design Factors
