Should You Order a CNC or 3D-Printed Prototype First?





Order a 3D-printed prototype first if you only need to check shape, fit and look. Order a CNC prototype first if the part must be made in a real production material and hold tight tolerances. At HLH Prototypes Co LTD we decide by asking what the prototype has to prove.

 

KEY FACTS

·        HLH Prototypes Co LTD has been helping people make parts and products since 2008.

·        Our minimum order quantity starts at 1 for prototypes.

·        We offer CNC milling, SLA and SLS 3D printing, vacuum casting, sheet metal and rapid injection moulding under one roof.

·        Our 12000 sq/m manufacturing facility in China is split across six dedicated zones.

 

When should you order a 3D-printed prototype first?

Order a 3D print first when the design is still moving. A printed part is a quick way to hold the shape in your hand, check how it sits with neighbouring parts and show it to clients.

Our 3D printing prototyping covers SLA and SLS. SLA suits smooth, detailed visual models, while SLS suits tougher parts you can handle and test.

When is a CNC prototype the better first order?

A CNC prototype is the better first order when the part has to behave like the finished product. Machining cuts from solid stock, so you get real aluminium, stainless steel or engineering plastic with accurate dimensions.

That matters for load-bearing brackets, sealing faces and moving assemblies. Our CNC prototype service suits these jobs, and rapid prototype machining is often the quickest route to a metal part you can trust.

How do the two compare side by side?

The right choice depends on what you need to learn from the first part.

Question

3D-printed prototype

CNC prototype

Best for

Early shape and fit checks

Functional testing and tight tolerances

Material

Printable resins and powders

Production metals and plastics

Design stage

Still changing

Mostly settled

 

What about a plastic prototype for moulding?

If your product will be injection moulded, a plastic prototype is where this decision ends up. Print or machine first to prove the design, then move to tooling once you are confident.

Our rapid injection moulding service picks up from there, with quantities from 1 piece up to around 100,000 parts.

Frequently asked questions

Q  Can I order both at the same time?

Yes. Many customers print one version for a visual check and machine another for testing.

Q  Is a CNC prototype always more expensive?

Not always. Cost depends on geometry, material and finish, so a project review will give you real figures.

Q  Can you make just one part?

Yes. Our minimum order quantity for prototypes starts at 1.

China Injection Mold – How to Manufacture Successfully in China

China is one of the places where you can find low-cost manufacturing and prototyping services. You have to be careful when choosing a manufacturer to work with. To ensure success in your next  China injection mold  project, you’ll have to consider your requirements and the capability and experience of a prospective manufacturer in fulfilling those. Here are some tips to help increase your chances of success: Understand how the process Plastic injection molding involves injecting hot molten plastic into a custom metal mold. The plastic is left inside the mold to cool, solidify, and take the mold’s shape. That makes the process practical for building custom plastic products, including car components, packaging, tools, medical equipment, fasteners, and toys. Make sure that your preferred manufacturer can create the custom  China injection mold , so you won’t have to look further, and you can save time. Ensure high-quality molds The molds must be made of high-quality,...

Understanding the Advantages of Rapid Injection Molding

When you need prototypes or parts fast, consider having them done via rapid injection molding. The manufacturing method is particularly useful for low to mid volume production where rapid tooling might be inefficient or incapable of producing the exact results you want. Chinese injection molding companies are trusted by discerning manufacturing companies with tight deadlines and the need to test a new product in the market. With rapid injection molding, you can get the parts done quickly and efficiently using real materials. Rapid injection molding used to be reserved for mass production, where large companies would turn to manufacturers in China for an injection mold . However, it can actually also be flexible for creating high-quality prototypes. Moreover, it can be done as injection molded parts. Rapid tooling or bridge tooling is capable of delivering quality parts for low volume production requirements of up to 100,000 pieces from product resins. Think of it as an end-use...

Know All About SLS Rapid Prototyping

  Many additive manufacturing technologies exist today, and one of them is selective laser sintering (SLS) 3D printing. It’s popular with manufacturers and engineers for its high productivity, low cost per part and reliable materials to build accurate aesthetic models and prototypes.  SLS rapid prototyping  can build prototypes from a range of plastics, but reputable service providers use either nylon (PA 12) or PA 12 glass-filled. Let’s explore the process to help you learn more about it and if it’s suitable for your next project. How it works SLS 3D printing is an industrial 3D printing technology that builds durable and accurate parts with a precision laser to fuse the powder materials one layer at a time. Powder surrounds the part during the building process, so there’s no need for support structures to realize complex features and overhangs. After printing, the finished prototype is removed from the build chamber, separated, and rid of excess powder, which is reu...
