ScanTrainer Medical Prototype Housing with Durable Print

Medical product built under pressure

ScanTrainer is a training simulator line under Surgical Science, a medical simulation company based in Gothenburg, Sweden. For this prototyping job, the real engineering question was simple for Mastars: could a sample housing look close to production intent, keep its printed marks after alcohol wiping, and still assemble without fit drift?

The part appears to be an outer housing panel commonly seen in medical simulation equipment. Based on the customer's requirements, this prototype had to cover mold-ready geometry, medical-grade material direction, cosmetic consistency, and repeatable assembly alignment from the first sample round.

Mastars-built prototype housing with durable print, precision features, and post-finish quality control.

From DFM to sample control

The difficult part was not making a display sample. It was building a prototype that could support engineering review while holding +/-0.02 mm in critical areas and keeping the silk screen stable through alcohol resistance checks.

Mastars handled it as a serious validation sample. We would start with DFM feedback, review the geometry for molding feasibility, then lock process controls around profile stability, hole position, visible surfaces, and print placement. For a medical device part like this, inspection planning also needs traceable checks on critical dimensions, surface quality, and silk screen performance before the team moves further into tooling decisions.

What the customer could verify

The customer received a prototype sample that could support design review, fit checks, and process decisions earlier.

✅ Prototype route cut upfront validation cost by about 34% against early tooling

✅ First sample dimensional acceptance reached 98% on critical mounting features

✅ Sample lead time dropped from 18 days to 8 days

✅ Alcohol wipe checks kept printed markings clear through repeated internal verification

✅ Prototype finish supported assembly review and appearance sign-off much earlier

This kind of pressure is not unique to medical simulation equipment. Once a prototype part needs appearance, printed identification, and assembly fit at the same time, the sample starts doing real engineering work instead of just showing the shape.
