Concept and ergonomics
Check proportions, grip and placement before locking down the design.
Test before production
Rapid prototyping for better decisions
Physical prototypes for fit, function and design validation, from early concept to production-like test part.
- Focus
- Shape, fit and function
- Approach
- Short, measurable iterations
- Process
- FDM or SLA by test objective
A useful prototype answers a specific question. Early models can check size and ergonomics; later versions may validate assembly, loading or finish. Matching process and material to each iteration prevents spending on qualities that are not needed yet.
Three common prototype stages
Fit and assembly
Test interfaces, hole patterns, clips and clearance against neighbouring components.
Function and presentation
Evaluate movement, loading or appearance with a more production-like model.
Decide what each version must prove
A prototype rarely needs to replicate the final product in every respect. Focusing on one or two risks per iteration makes development faster and results easier to interpret.
Tell us which parts interface, which dimensions are critical and how the test will be conducted. We can then choose an appropriate material level and avoid unnecessary finishing in early stages.
- Give each version a clear test objective
- Mark interfaces with other components
- Record changes between iterations
A controlled prototype cycle
- 01
Define the test
We clarify what the prototype must validate and the accuracy it needs.
- 02
Make and evaluate
The model is printed for practical testing of the chosen questions.
- 03
Refine and confirm
Findings feed back into the CAD model for another iteration or production.
Input for an effective prototype
Most important is the decision the prototype needs to help you make.
- Current STEP or STL file
- What the prototype must validate
- Mating components
- Critical dimensions and clearance
- Intended test conditions
- Timeline and expected iterations
Prototyping questions
Must the prototype use the final material?
Not always. A shape or fit model can use a simpler material. Functional testing should, however, reflect relevant properties such as stiffness, toughness or heat resistance.
Can you review my CAD model?
Yes. We can flag wall thickness, fits, orientation, support surfaces and features that may be difficult to print.
How many iterations are needed?
It depends on complexity and what has already been validated. We suggest a limited test objective for each version so that findings are actionable.
Which process is best for visual prototypes?
SLA often provides finer features and smoother surfaces. FDM may be better for larger models or when functional feedback matters more than cosmetic finish.
Can a prototype be used for load testing?
Yes, if the load case, test level and safety margin are understood. A printed prototype does not automatically validate a final production process.
