  1. RAPID PROTOTYPING Evan Potter Day 1-3 Class 5-6 Mr. White

  2. What is rapid prototyping? • Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology.

  3. When Was it first used? • The first techniques for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts.

  4. How is it used today? • Today, they are used for a much wider range of applications and are even used to manufacture production-quality parts in relatively small numbers. Some sculptors use the technology to produce exhibitions.

  5. What does it work? • The use of additive manufacturing for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software, transforms them into thin, virtual, horizontal cross-sections and then creates successive layers until the model is complete. It is a WYSIWYG process where the virtual model and the physical model are almost identical.

  6. With additive manufacturing, the machine reads in data from a CAD drawing and lays down successive layers of liquid, powder, or sheet material, and in this way builds up the model from a series of cross sections. These layers, which correspond to the virtual cross section from the CAD model, are joined together or fused automatically to create the final shape. The primary advantage to additive fabrication is its ability to create almost any shape or geometric feature.

  7. Who uses it?

  8. is there other prototyping technology?

  9. What is the cost? • ZCorp 350 Printer $50,000 + $10,000 (for tax and 1 year maintenance package). Material cost = $3 a cubic inch (also accounts for glue used in post-processing). • Objet Eden 350 Printer $150,000 (after tax and maintenance). Material cost is 50 cents a cubic cm or $10 a cubic inch. • Conventional rapid prototype machines cost around $25,000.
