Rapid Prototyping Service

Rapid prototyping is a manufacturing process used to quickly create physical models of a product design for testing, validation, and refinement before full-scale production.

The most common rapid prototyping methods include 3D printing (SLA, SLS, FDM), CNC machining, sheet metal fabrication, vacuum casting, and rapid injection molding.

The turnaround time depends on the complexity, material, and process used. 3D printing and CNC machining can produce prototypes in as little as one day, while rapid injection molding typically takes 1-3 weeks.

 

 

 

 

Materials vary by method but include plastics (ABS, PLA, Nylon, ULTEM), metals (aluminum, steel, titanium), and composites.

 

 

 

 
  • Faster product development
  • Lower costs for testing and iteration
  • Quick design validation
  • Early market testing before mass production

 

 

 

 

Accuracy depends on the method used. CNC machining and SLA 3D printing provide high precision (±0.05 mm or better), while SLS and FDM may have slightly lower tolerances.

 

 

 

Use rapid prototyping when you need fast, low-cost prototypes for design validation, functional testing, or market feedback before investing in full-scale production.

Yes, in some cases. Rapid injection molding, CNC machining, and high-performance 3D printing (SLS, SLA, and FDM with industrial materials) can produce small-batch production parts suitable for real-world use.

By identifying design flaws early, rapid prototyping prevents expensive mistakes, reduces rework, and minimizes tooling costs before mass production begins.

 

 

 

Industries such as defense, aerospace, medical, communication,  consumer electronics, and industrial manufacturing use rapid prototyping to accelerate innovation and reduce time to market.
