Choose the Right Prototyping Process

The best process depends on what you need to validate — fit, function, material performance, appearance, or manufacturability.

CNC Prototyping
Best for functional prototypes that require production-grade metals or engineering plastics, controlled tolerances, threads, mating surfaces, or realistic mechanical performance.
Best for: Functional testing · Precision parts · Metal prototypes
3D Printing Prototyping
A fast option for design iterations, complex geometries, concept models, and form-and-fit testing without the need for tooling.
Best for: Concept models · Complex parts · Appearance testing · Fast iteration
Sheet Metal Prototyping
Suitable for brackets, panels, housings, enclosures, chassis, and other fabricated metal parts that need to be tested in their intended material and form.
Best for: Enclosures · Brackets · Panels · Structural parts
Rapid Tooling & Injection Molding
A practical option when you need multiple near-production plastic parts for functional testing, material validation, assembly trials, or pilot production.
Best for: Molded plastic parts · Pilot runs · Material testing · Pre-production validation

What Do You Need to Validate?

A useful prototype should answer a specific engineering question before you commit to production.

Fit

Assembly, clearances, interfaces, threads, and mating features.

Function

Strength, motion, sealing, thermal behavior, and mechanical performance.

Material

Performance of production-grade metals, plastics, or molded resins.

Appearance

Geometry, surface finish, texture, color, and presentation.

Production Readiness

Tolerance, manufacturability, repeatability, and inspection requirements.

Not sure which process fits your project? Send us the CAD file and tell us what the prototype needs to prove.

Prototype

Validate geometry, fit, material, function, and design assumptions.

Pilot Build

Confirm repeatability, assembly, inspection requirements, and production readiness.

Repeat Production

Optimize manufacturing, fixtures, quality control, and batch consistency as volume increases.

Baosheng coordinates prototypes, pilot batches, and repeat production through one project and quality-control workflow, so you can scale without starting over with a new supplier.

From Prototype to Production

Your manufacturing requirements change as the design becomes more mature.

From Precision Prototypes to Low-Volume Production

Why Engineers Work With Baosheng

Engineering Review Before Production

We review materials, tolerances, geometry, tool access, wall thickness, and other manufacturability risks before production begins.

Drawing-Based Inspection

Critical dimensions and inspection requirements are confirmed against your drawings. Dimensional reports, CMM reports, and material documentation are available when required.

One Project Contact

Quotation, engineering feedback, production updates, inspection, and delivery are coordinated through one point of contact.

Prototype-to-Production Support

Move from one-off prototypes to pilot builds and repeat production with manufacturing and quality requirements carried forward as the project develops.

From CAD File to Prototype

01. Send Your Files

Upload your 3D CAD model, drawing, quantity, material, finish, and project requirements.

02. Engineering Review

We review the design, tolerances, material, manufacturing process, and potential DFM issues before production.

03. Manufacture & Inspect

Your parts are manufactured using the selected process and inspected according to the agreed requirements.

04. Test and Move Forward

Use the prototype for validation. If the design is approved, we can support the next revision, pilot batch, or production order.

What Should You Send for a Faster Quote?

For a more accurate prototype manufacturing review, send:

  • 3D CAD file, preferably STEP or STP
  • 2D drawing if tolerances are specified
  • Required quantity
  • Material
  • Surface finish
  • Critical dimensions or inspection requirements
  • Target delivery date
  • What the prototype needs to validate

If some details are not final yet, send the CAD file first. Our engineers can review the design and help identify a practical manufacturing route.

Rapid Prototyping FAQ

It depends on what you need to test. CNC machining is often preferred for functional prototypes in production-grade materials, while 3D printing is useful for fast iterations and complex geometries. Sheet metal is suitable for fabricated enclosures and brackets, while rapid tooling is better for multiple near-production molded parts.

Yes. Baosheng supports one-off prototypes, pilot quantities, and repeat production depending on the manufacturing process.

Yes. CNC machining and sheet metal fabrication can use a wide range of production-grade metals and engineering plastics. Material options for 3D printing and injection molding depend on the selected process and project requirements.

Yes. We support the transition from rapid prototyping to pilot builds and repeat production, including manufacturing optimization and documented inspection requirements.
