  1. 1. 3D Printing CHAN Choi Ching 15227243 HUI Ming Ho 15215903 NG Pui Yiu 15217787
  2. 2. Contents ○ Mind Map ○ Background and history ○ Mechanism ○ Materials ○ Development and application ○ Pros and Cons ○ Survey Results
  3. 3. Mind Map ○ https://www.mindmeister.com/582447886/3d -printing
  4. 4. Objectives ○ Understand the mechanism of 3D Printing and its own application ○ Analyze the public opinion towards 3D Printing ○ Identify the pros and cons of 3D Printing
  5. 5. Background ○ 3D Printing (Additive Manufacturing) ○ Three-dimensional object from digital file(STL) ○ Either using a 3D modeling program (create new) or a 3D scanner (existing object) ○ ‘Sliced’ into successive layers (horizontal cross-section)
  6. 6. History ○ Developed by Chuck Hull in 1984 ○ Originally known as ‘Rapid Prototyping’ ○ Most common method: stereolithography (STL) ○ Price in 2007 ~USD10000 ○ First commercial 3D Printer launched in 2009
  7. 7. Mechanism Modeling Printing Finishing
  8. 8. Modeling ○ Scanning the desired product by a 3D scanner or create a model by using Computer Aided Design (CAD) ○ Collect geometric data for computer to make a digital model ○ ‘Sliced’ into layers ○ Convert the data into a readable file for 3D printer (.slt)
  9. 9. Printing Type Technology Extrusion Fused deposition modeling (FDM) Fused Filament Fabrication (FFF) Light polymerized (Vat Photopolymerization) Stereolithography (SLA) Digital Light Processing (DLP) Power Bed Powder bed and inkjet head 3D printing (3DP) Electron-beam melting (EBM) Selective laser melting (SLM) Sheet Lamination Selective Deposition Lamination (SDL)
  10. 10. Materials ○ Thermoplastics ○ Rubber ○ Metals & Alloys ○ Ceramics powder ○ Modeling Clay ○ Paper ○ Photopolymers
  11. 11. Application ○ Medical Industry (Bio-Printing) ○ Aerospace and Aviation Industry ○ Automotive ○ Art/Design/Architecture ○ Food Industry ○ Personal/Consumer use
