Are 3D printed prototypes strong enough for testing?

Many are. Strength depends on process, material, print orientation, geometry, and load case. FDM PETG and nylon handle most functional tests; SLA standard resin suits detail and cosmetic checks.

Can I prototype from a STEP file?

Yes. STEP files are accepted and can be used for 3D printing workflows when the geometry is suitable.

What is the cheapest prototype process?

FDM is usually the cheapest way to validate form and fit. SLA costs more but is better for detail and finish. FDM nylon covers durable parts.

TEST THE SHAPE. THEN TEST THE PART.

Use 3D printed prototypes to shorten the loop between design and physical feedback. Print early for fit, print better for function, then switch process when the design earns it.

WORKFLOW

FROM FILE TO PART

STEP 01
Pick the question
Decide what this prototype needs to prove: size, assembly, finish, strength, customer response, or production risk.
STEP 02
Choose process
Use FDM for speed and low cost, SLA for detail, or FDM nylon for stronger functional geometry.
STEP 03
Print
The lab produces the part and flags obvious manufacturability issues.
STEP 04
Iterate
Update the CAD and repeat until the design is ready for machining, assembly, or batch production.

Prototype fidelity should increase in stages

Early prototypes should be cheap and fast. Later prototypes should become more accurate, stronger, smoother, or closer to final material as the design risk narrows.

Printed does not mean rough

FDM can be fast and functional, SLA can be crisp and presentable, and FDM nylon can produce durable shapes that hold up to repeated handling and load.
