From CAD to Reality: How Rapid Prototyping with Additive Manufacturing Works

What Is Rapid Prototyping?

Rapid prototyping is a fast, cost-effective method of transforming digital designs into physical parts. It enables product developers to test form, fit, and function in a matter of days, not weeks. Among the various rapid prototyping methods, additive manufacturing (3D printing) stands out for its speed, material efficiency, and design freedom.

At Kaierwo, we provide comprehensive prototyping services, from 3D printing and CNC machining to vacuum casting, helping our clients move seamlessly from CAD models to functional prototypes.

Our Core Capabilities: Turning Ideas into Real-World Parts

1. CAD File Analysis & DFM Optimization

Upload your STP, IGS, or STL files, and our engineering team will review your design for manufacturability (DFM).

We provide design feedback within 12–24 hours.

2. Additive Manufacturing (3D Printing)

FDM, SLA, SLS printing options for plastics and resin.

Ideal for early-stage conceptual models and complex geometries.

Rapid turnaround: as fast as 24–48 hours.

3. CNC Machining for Precision

3-axis to 5-axis CNC aluminum machining ensures tight tolerances and fine finishes.

Perfect for functional prototypes, assemblies, or parts requiring mechanical testing.

4. Vacuum Casting for Short-Run Replication

Once your prototype is validated, we offer vacuum casting to create up to 50+ units with consistent appearance and performance.

Great for bridge tooling and pilot production runs.

Prototyping Workflow: From CAD to Reality

Step	Process	Description
1	CAD File Upload	Send us your 3D model (STP/STL/IGES)
2	Design Review	We evaluate the file for printability/machinability
3	Additive Manufacturing	We 3D print or CNC machine your part as per material and purpose
4	Finishing & Post-Processing	Deburring, polishing, painting, or assembly
5	Delivery	Prototypes ready to ship globally in 3–7 days
