Rapid Prototyping by Three Routes

What this page covers

• CNC machining for accurate parts with real engineering materials
• 3D printing for complex shapes and custom parts without tooling
• Vacuum casting for a run of plastic parts that look and feel close to moulded parts
• A comparison of the three routes before a prototype is committed, so cost and accuracy are weighed together

What to confirm before ordering

CNC suits high accuracy and strong surface quality; 3D printing suits complex geometry and custom shapes, while its layer lines are visible and post-processing is needed, as the company website itself states. Vacuum casting suits a limited run of plastic parts from a silicone mould. Before ordering, confirm minimum order quantity and lead time for your drawings.

Drawing checklist

Send the drawing with units and scale stated, the material and grade, the critical dimensions and tolerances marked, and the finish required. State the quantity you need checked and the question the part must answer: fit, function or appearance. Uploaded files are used only for the quotation, and non-disclosure agreements are supported.

Quality checks

Parts are inspected with a coordinate measuring machine, a projector and height gauges, with quality control at each production stage, and a dimension report can be provided for a project on request.
