Rapid Prototyping With LangHe

With cutting-edge technology and elite engineers, high-quality prototypes are delivered by CNC machining, rapid 3D printing, sheet metal fabrication, die casting, injection molding, etc.

What is Rapid Prototyping?

Rapid prototyping is a fast and cost-effective process used to create physical models of parts or designs quickly, allowing for early testing and evaluation. Using technologies like 3D printing, CNC machining, and sheet metal fabrication, prototypes are produced in just 1-3 business days. This enables designers to test multiple iterations and refine designs before committing to full-scale production.

The main advantage of rapid prototyping is its ability to validate a design early, reducing the risk of costly mistakes. By providing a tangible model, teams can assess functionality, identify flaws, and evaluate materials or components without the need for expensive molds or tooling.

In summary, rapid prototyping accelerates product development, minimizes risk, and supports innovation by enabling early-stage design evaluation and refinement.

Our Rapid Prototyping Capabilities

Whether you need a plastic or metal prototype, an appearance or a functional prototype, our engineering team will evaluate the best production process based on the drawings to meet your needs.

5-Axis CNC Machining

Rapid CNC Machining

CNC milling and CNC turning are excellent options for rapid prototyping, especially when parts need to be evaluated in their final material and cut from fully dense stock. This process allows the machining of a wide range of metals and plastics, with many CNC parts being manufactured and shipped within a week. Expedited CNC options are available for faster turnaround, and competitive, market-based prices make it possible to order multiple prototypes at once for quick product evaluation.

Rapid 3D Printing

3D printing is one of the fastest and most affordable rapid prototyping methods, offering quick turnaround times and low-cost solutions. At LangHe, some 3D-printed parts can be built and shipped in as little as one day for just a few dollars.

The three most commonly used 3D printing processes for rapid prototyping are Selective Laser Sintering (SLS), Stereolithography (SLA), and Fused Deposition Modeling (FDM).

SLS: Versatile and cost-effective, offering good speed, functional properties, and resolution.
SLA: Provides the best surface finish and high detail accuracy, ideal for clear parts.
FDM: Capable of producing large parts up to 36” using durable thermoplastics like ABS and ULTEM.

Rapid Injection Molding

Rapid Injection Molding

Rapid injection molding is a process that produces durable, identical parts for testing, with multiple backup parts available. It is ideal for high-fidelity product evaluations and bridge tooling for temporary production during product launches. The typical lead time for rapid tooling is 2-3 weeks, but LangHe’s Quick-Turn Molding option can deliver parts in as little as five days.

Although slower than 3D printing or CNC machining, rapid injection molding is often the best choice when high-volume parts with strict material and mechanical requirements are needed. It offers high repeatability and near-net final shapes, making it perfect for prototypes that closely resemble the final product.

Rapid Sheet Metal Fabrication

Rapid sheet metal fabrication is an excellent choice for quick-turn flat parts that need to be evaluated in their final metal material. Parts can typically be produced in a week or less, making it cost-effective to manufacture multiple prototypes in parallel. Aluminum 5052 is commonly used for rapid prototyping, though a variety of alloys, including steel, copper, and stainless, are also available.

While the lead time for rapid sheet metal parts is similar to that of CNC machining, it is longer than 3D printing due to the additional machine setup and run time required for fabrication.
