  3. Introduction • Rapid Prototyping (RP) techniques are methods that allow designers to produce physical prototypes quickly. • It consists of various manufacturing processes by which a solid physical model of part is made directly from 3D CAD model data without any special tooling. • The first commercial rapid prototyping process was brought on the market in 1987. • Nowadays, more than 30 different processes (not all commercialized) with high accuracy and a large choice of materials exist. • These processes are classified in different ways: by materials used, by energy used, by lighting of photopolymers, or by typical application range. 08MCD005

  5. Prototyping- What is it ? . Physical Model of the product . Degrees of Prototyping . Full Complete scale Model - functional model . Scaled Model - functional/ simulated material . Geometrical configuration 08MCD008

  6. Prototyping- Why? • Visualization • Design Change • Complex Object Fabrication • Testing Fit/ Packaging • Cost, Time, and Resource estimation • Process Planning • First to Market -- Critical for today’s industry • JIT concept (0 Inventory) • Rapid tooling / no tooling -- trend in technology 08MCD008

  7. Rapid Prototyping Processes • SLS --- Selective Laser Sintering • SLA --- Stereolithography • LOM --- Laminated Object Manufacturing • FDM --- Fused Deposition Modeling • Others 08MCD008

  8. Rapid prototyping Processes- SLS Selective Laser Sintering 08MCD003

  9. Rapid prototyping Processes- SLS Application Range • Visual Representation models • Functional and tough prototypes • cast metal parts Advantages • Flexibility of materials used • No need to create a structure to support the part • Parts do not require any post curing except when ceramic is used. Disadvantages • During solidification, additional powder may be hardened at the border line. • The roughness is most visible when parts contain sloping (stepped) surfaces. 08MCD009

  10. Rapid prototyping Processes- SL Stereolithography 08MCD002

  11. Rapid prototyping Processes- SL Application Range • Parts used for functional tests • Manufacturing of medical models • Form –fit functions for assembly tests Advantages • Possibility of manufacturing parts which are impossible to be produced conventionally in a single process • Can be fully atomized and no supervision is required. • High Resolution • No geometric limitations Disadvantages • Necessity to have a support structure • Require labor for post processing and cleaning 08MCD010

  12. Rapid prototyping Processes • Other Processes • Ballistic Particle Manufacturing (BPM) • This process uses a 3D solid model data to direct streams of material at a target. • 3D Printing • It creates parts by layered printing process. The layers are produced by adding a layer of powder to the top of a piston and cylinder containing a powder bed and the part is being fabricated. • Model Maker • It uses ink jet printer technology with 2 heads. One deposits building material, and the other deposits supporting wax. 08MCD004
