Materials

Wide Range of Prototyping Materials

Choose by function, finish and environment — we will recommend the closest production-equivalent material.

SLA

Photopolymer Resin

High detail, smooth surfaces, clear and engineering grades for appearance and fit checks.

SLS

Nylon PA12 / PA11

Durable, functional parts with good chemical resistance and living-hinge behaviour.

FDM

ABS, PC, PETG, TPU

Large fixtures, enclosures and flexible parts where cost and speed matter most.

Metal

Aluminum & Stainless

SLM / DMLS metal prototypes for brackets, housings and functional testing.

Casting

Polyurethane & Silicone

Rigid, flexible and rubber-like cast parts with colour matching and textured finishes.

Finishing

Paint, Texture, Plating

Primer, colour matching, soft-touch, texture, laser marking and assembly.

Process

From CAD to a Finished Prototype in 4 Steps

A dedicated engineer reviews the model before anything is built, so you know the risks before you spend.

STEP 01

CAD & DFM review

Geometry, wall thickness, supports, tolerance and finish reviewed within 24 hours.

STEP 02

Build

SLA, SLS, FDM, silicone mold or bridge tooling selected against your deadline and volume.

STEP 03

Post-processing

Support removal, sanding, paint, texture, inserts and assembly to match the final part.

STEP 04

Inspection & ship

Dimensional report, photos and export packing, with full traceability.

Quality

Prototype Quality You Can Measure

What every project includes

  • DFM feedback before the build
  • Dimensional report and photos before shipment
  • Material and finish matched to the production intent
  • Optional FAI and PPAP support for bridge tooling

Inspection & equipment

Mitutoyo / Renishaw CMM, height gauges, surface and colour checks, plus ISO 9001, IATF 16949 and ISO 13485 workflow.

FAQ

Questions Before You Send a Model

How fast can I get a prototype?

Simple FDM or SLA parts can ship in 24 hours. SLS and silicone casting typically take 3–5 days after DFM approval.

What files should I send?

STEP, STL, IGES, OBJ or a native CAD file. A 2D drawing helps when tolerances or finishes are critical.

Can you match the production material?

We recommend the closest prototype equivalent, then confirm the final production resin or metal during DFM review.

Can you do low-volume production?

Yes. Silicone casting covers 10–200 parts, and bridge tooling covers higher volumes before hard tooling.

Do you sign an NDA?

Yes. Tell us before sending files and we will issue a mutual NDA.

Send your CAD. Get a DFM review and prototype plan in 24 hours.

Tell us the process, material, quantity and target date. An engineer — not a sales rep — will review it and reply with a build plan and price.
