A prototype often has two jobs, to prove a design and to sell it. When appearance and accuracy carry that second job, SLA is frequently the right call.

Why SLA convinces

Smooth surfaces, crisp detail and tight tolerances mean an SLA prototype can closely resemble a finished, moulded product. That helps in client presentations, investor meetings and design reviews where a rough part undersells the work.

It also makes for accurate fit checks where small features matter.

The right tool for the stage

For early, rough iterations, FDM is fast and cheap. For the polished prototype that has to impress, SLA earns its keep. Tell us where you are in the process and we will suggest the best fit, then get you a quote.
