Manufacturing Processes

Bringing your product from 2d sketches and 3d models into real life hands on parts can be a daunting task. Below is a list of manufacturing processes that can be used with brief descriptions on each.

  • Additive manufacturing
    • Fused deposition modeling (FDM) or fused filament fabrication (FFF) is the most common additive manufacturing technology. It lays down material in layers, fed by raw material filament (often a plastic). It is great for initial rapid prototypes or rough durable parts.
      • Benefits: cost, durability, speed
      • Cons: surface finish, accuracy
    • Stereolithography (SLA) works by curing a photo-reactive resin with a UV laser or similar power source
    • Multijet technology (MJM or polyjet)
    • Selective laser sintering (SLS)
    • Selective laser melting (SLM) or direct metal laser sintering (DMLS)
  • Machining
    1. Lathe
    2. Mill
  • Casting
    1. Centrifugal
    2. Continuous
    3. Die
    4. Investment casting (lost wax)
    5. Sand casting
  • Molding
    1. Injection
    2. Transfer
    3. Extrusion
  • Forming
    1. Forging
    2. Rolling
    3. Pressing
    4. Bending
    5. Shearing
  • Joining
    1. Welding
    2. Brazing
    3. Soldering
