Rapid CNC Prototyping Service
CNC machining, including both CNC milling and CNC turning, is an excellent choice for rapid prototyping when parts need to be assessed in their final material form. This method allows for prototypes to be made from fully dense stock, providing accurate and durable models. FactoryAssist specializes in machining a broad spectrum of metals and plastics, ensuring versatility for your project requirements. Our rapid CNC prototyping services deliver high-quality machined prototype quickly, often in 1 day. This speed, coupled with our cost-effective pricing, allows engineers to order multiple prototypes at once, facilitating quick and thorough product evaluations.
Maximum Part Size:
CNC Milling: 4000×1500×600 mm
CNC Turning: 200×500 mm
Standard Lead time: 1 day
Tolerance: 0.001 inches
Prototype Injection Molding
Injection molding is a top choice for prototyping when you need highly durable and consistent parts for extensive testing. This method is perfect for high-fidelity product evaluations and for creating temporary bridge tooling during product launches. Rapid injection molding typically has a lead time of 2-3 weeks for initial parts, but with FactoryAssist’s expedited services, you can receive parts in as little as five days.
Maximum Part Size: 1200×1000×500 mm
Standard Lead time: 2-3 weeks
Mold Cavity Tolerance: +/- 0.05 mm
3D Prototyping (SLS or SLA)
3D printing stands out as the leading method for rapid prototyping due to its speed and cost-effectiveness. This technique enables the quick and economical creation of prototypes, often ready for dispatch within a day at minimal cost. The primary 3D printing methods for rapid prototyping include Selective Laser Sintering (SLS), Stereolithography (SLA), and Fused Deposition Modeling (FDM).
SLS is highly versatile, offering a balance of speed, mechanical functionality, detailed resolution, and affordability. SLA provides the finest surface finish and exceptional accuracy, making it perfect for creating clear parts with precise tolerances. FDM is ideal for producing larger parts from a variety of engineered thermoplastics.
Max. Build Size: 1400x700x500mm
Standard Lead time: 4-6 days
Dimension Tolerance: ±0.2mm (For >100mm, apply 0.15%)


Vacuum Casting Prototyping
Vacuum casting is a preferred prototyping technique for producing high-quality, detailed replicas quickly and cost-effectively. This method is especially advantageous when you need small to medium quantities of functional plastic parts with the quality of injection-molded products. It allows for the precise replication of details and textures, making it perfectly suited for test marketing, functional testing, and proof-of-concept demonstrations.
Maximum Part Size: +/- 0.025 m
Standard Lead time: Up to 20 parts in 15 days or less
Tolerance: ±0.05 mm
