Additive Manufacturing (Dry Process (Fused Deposition Modelling (How does…

- - - - Build the part one layer at a time
      - Each layer is constructed from a ultraviolet laser which is directed by X and Y scanning mirrors
      - The liquid material will indexed down to make room for the next layer as the laser traces on the surface of the resin.
      - A recoater blade moves across the surface ensuring there is a thin coat of fresh liquid resin is evenly spread over the object
      - After the part is finished, a chemical bath is need to remove excess resin and later the part is cured in an ultraviolet oven (The support structures are also removed at the same time). Moreover, hand sanding and professional painting are available for finishing process.
    - - Resins
- - - - 1st : "Slicing" 3D CAD data into layers
      - 2nd : Send to the machine which constructs the parts layer by layer
      - 3rd : Remove from the platform and clean the support material
      - 4th : Hand sanding, assembly and cosmetic paint
    - - Thin thread-like spools of thermoplastic and support material
        
        ABS, Polycarbonate and Ultem
  - - - 1st : A leveling roller spreads a thin layer of powered material across the power bed
      - 2nd : CO2 laser traces the cross-section on the material.
        
        The material is heated and fused together as the laser scans the surface
        
        The powder bed will be lowered to make room for the next layer once a single layer is complete
      - 3rd : Once the parts are built, they are encompassed by unsintered powder which provides supplemental strength and eliminates the need for support structures
      - 4th : Remove and clean the excess material. The unused material will then be reused on producing the next part.
    - - Powdered Nylon 11, Nylon 12 and Polyether Ether Ketone(PEEK) materials
