Summary

Rapid prototyping (RP) uses digital designs and fast fabrication methods to create physical models or parts for testing. It helps teams evaluate ideas and make changes before committing to full production.

Rapid prototyping is a group of techniques for quickly fabricating a novel physical part, usually for initial product testing. A designer creates the model using computer-aided design (CAD) software, then a fabrication process—often 3D printing—builds the part.

What is rapid prototyping?
A group of techniques for quickly fabricating physical models or parts, often for testing and refinement.
What makes a geometric model valid for fabrication?
It has a closed boundary enclosing finite volume, with no exposed holes or self-folding surfaces.
What role does STL play in rapid prototyping?
It is a common transfer format that approximates model surfaces with small facets.
What is slicing in additive manufacturing?
Computationally dividing a 3D model into layers that guide sequential fabrication.
How does Fused Deposition Modeling build a part?
It deposits fused filament along programmed paths.

Quiz questions

  1. How does stereolithography (SLA) form successive layers?Answer: A laser cures liquid photopolymer.
  2. Which method is a programmed machining process rather than an additive process?Answer: CNC machining
  3. How can physical prototypes help product teams gather user feedback?Answer: Users can interact with models to reveal usability and user-needs issues.
  4. Why might a prototype fail to predict a finished product's behavior?Answer: Its material or fabrication process may differ from those used in production.
