Fused deposition modelling/ 3D printing

• What is the process of fused deposition modelling (FDM)

  Uses 3D CAD drawings

  processing software slices the drawing

  extruder builds the product from bottom up, layer by layer
• What material is usually used in fused deposition modelling?

  Thermoplastic filament
• What are some benefits of FDM?

  Quick

  accurate

  cost effective
• What are some uses for FDM?

  Prototypes for clients

  full-size models for moulds for casting and dies
• What are some applications of FDM beyond prototyping?

  bespoke production

  e.g., cast jewellery patterns, custom cutlery grips for arthritis
• What are the capabilities of metal 3D printing?

  complex components

  bespoke production

  no need for part fabrication or machining from solid (waste reduction)
• What materials are used in metal 3D printing?

  Titanium

  stainless steel

  aluminium
• What are the methods of metal 3D printing?

  electron beam melting (EBM)

  selective lazar melting (SLM)
• What is electron beam melting?

  Uses electron beams to fuse metal powder layer by layer
• What is selective lazar melting?

  Uses lazar beams to fuse metal powder layer by layer
• What are some applications of metal 3D printing in the medical field?

  custom made skeleton joints

  prosthetics

  Other medical devices
• What form does the metal take before being 3D printing?

  Powder
