3D Printing

• 3D Printing 


  An additive manufacturing process where objects are built layer by layer from digital models.
• Types of 3D Printing - Fused deposition modelling (FDM)


  Uses a heated nozzle to extrude plastic filament.
• Types of 3D Printing - Stereolithography (SLA)


  Uses a UV laser to cure photopolymer liquid resin.
• Types of 3D Printing - Selective laser sintering (SLS)


  Uses a laser to fuse powdered material.
• Common materials - PLA


  Biodegradable, used for prototyping.
• Common materials - ABS


  Stronger but prone to warping.
• Common materials - Photopolymer resin


  Used for high detail prints in SLA printer.
• Common materials - Nylon (PA-polyamide)


  Durable, used for functional parts (FDM and SLS)
• Advantages

  Enables complex designs

  Reduces waste materials

  Faster prototyping compared to traditional manufacturing
• Disadvantages

  Can be slow for large parts

  Limited material strength for some applications
• Safety

  Ensure proper ventilation when printing ABS or resin.

  Avoid touching heated printer components.
