Brynnage Design creates solid 3-D models using 3-D CAD drawings with a .STL extension.
When determining to have a rapid prototype made, several questions should be considered:
- What is the product end use?
These help in the selection of materials to build the model as well as the process for making the production parts.
- What is the purpose of the model?
Visual Only?
Fit Test?
Proof the design for manufacturability?
Sales / Customer samples?
Functional test?
Mechanical Stress Test?
Sample for marketing materials?
Test assembly machinery?
- With regards to the Rapid Prototype Part
What is the temperature range?
Will it be exposed to high heat or extreme cold, i.e. beyond normal range)?
Will it be exposed to water? Different materials have different hydroscopic properties, meaning some will absorb moisture more readily than others.
Will it be exposed to chemicals? If so, which ones?
How will the product be used/tested?
How much impact resistance is required?
Is snap fit needed?
Will it be painted?
Will it be subject to secondary operations?
- Finish of the production part
What will the production part be made of plastic, metal, or other?
The same questions as above apply.
- Time Frame of the Rapid Prototype Part
How fast do you need it? Of course yesterday is the obvious choice!
