What are the types of Plastic Rapid Prototyping?


There are several types of plastic rapid prototyping methods. Here are some common ones:

  1. 1、Stereolithography (SLA): This method uses a UV laser to cure liquid photopolymer resin layer by layer, creating a solid object.

  2. 2、Selective Laser Sintering (SLS): SLS employs a high-powered laser to selectively fuse powdered plastic material, forming the desired shape.

  3. 3、Fused Deposition Modeling (FDM): FDM builds the prototype by extruding heated thermoplastic filament layer by layer.

  4. 4、PolyJet 3D Printing: This technique involves jetting photopolymer materials in thin layers and curing them with UV light to create the prototype.

  5. 5、CNC Machining: Computer Numerical Control (CNC) machining can be used to produce prototypes from plastic blocks or sheets by cutting away material with precision tools.

  6. 6、Vacuum Casting: This method involves creating a silicone mold from a master pattern and then pouring liquid plastic into the mold to produce multiple copies of the prototype.

  7. 7、Injection Molding: Although not strictly considered a rapid prototyping technique, injection molding is widely used for mass production of plastic parts. It involves injecting molten plastic into a mold cavity and allowing it to cool and solidify.

Each of these methods has its own advantages, limitations, and suitable applications. The choice of technique depends on factors such as desired prototype quality, complexity of the design, material requirements, and project timeline.
