Cosmetic review
Identify the show faces and expected finish. A polished resin model may be ideal for a design review without representing the final production material.
SOLUTIONS / BUILD / VALIDATE
Rapid prototyping for the decision you need to make
AIHFABS rapid prototyping
Use AIHFABS to move from a CAD revision to a testable part. Compare appearance models, fit checks and functional prototypes before committing to a production route.
TEST BEFORE YOU COMMIT
Choose a prototype around what you need to learn
A presentation model and a load-bearing test part answer different questions. AIHFABS helps you start with the purpose of the build.
| Test objective | Processes to review | What to validate |
|---|---|---|
| Appearance & presentation | SLA / DLP resin printing | Visible surfaces, small details, color and finishing requirements. |
| Fit & assembly | SLS / MJF nylon or CNC machining | Mating clearances, fastener access and dimensional interfaces. |
| Functional evaluation | CNC, metal printing or a suitable engineering polymer | Material properties, load direction and the actual test environment. |
| Early form studies | FDM printing | Overall size, ergonomics and iteration cost before detailed refinement. |
FROM CAD TO A USEFUL TEST
A short feedback loop, with a clear revision at every step
Keep the decision you need to make visible throughout the prototype order.
Upload the current revision
Send the model, required quantity and intended test. Add a drawing for critical dimensions and note surfaces that must look right.
Resolve manufacturing questions
Review material, orientation, tool access, supports and finishing. Do not assume that every prototype process produces the same surface or strength.
Measure what the prototype must prove
Check fit with its mating components and record test conditions. Compare the result with the requirement, rather than simply approving the appearance.
Update the design and plan the next build
Release a new revision for changes. When the design stabilizes, carry the accepted requirements into a pilot or production discussion.
BUILD THE RIGHT SAMPLE
Make the test conditions part of the brief
A useful prototype is one you can evaluate against a specific question.
Mechanical testing
Describe the load, temperature and contact conditions. Printed orientation and material choice matter when a sample will be stressed or repeatedly assembled.
Production handover
Save the drawing revision, material and finishing notes with the test outcome. A successful prototype does not automatically qualify a repeat manufacturing process.
