CNC Rapid Prototyping – All You Need to Know About It

CNC machining is one of the processes you’ll encounter as you search for rapid prototyping solutions online. CNC rapid prototyping is proven capable of delivering robust and high-precision parts quickly by cutting away at a billet or block of material with a series of drill bits and tools, carefully removing materials to create your product. The entire process is automated and computerized, with minimal human intervention.

But is CNC machining the best rapid prototyping solution for your project? Here are the things you must know about it to help you make an informed decision.

How it works

CNC rapid prototyping delivers custom parts from a range of metals and plastics. Service providers control tolerances to DIN-2768 Medium for plastics and Fine for metals to ensure optimum results. They use high-precision CNC mills, surface grinding machines, sink and wire EDMs, and lathes to deliver custom parts for any project. 5- and 3.4-axis machines are also available.


CNC machining is quick and repeatable, making it cost-effective for low-volume manufacturing. The prototypes deliver on high-tolerance and precise specifications, with excellent surface finishing. These qualities make the process preferred in the automotive industry.

Custom CNC rapid prototyping services are flexible and can deliver high-quality parts fast, whether you require performance plastics or production-grade metal parts. They can accommodate low- to mid-volume rapid machining production runs, too.

Design rules must apply.

Every rapid prototyping service has unique design rules you must follow to ensure successful prototypes. For instance, you’ll have to consider hole depth, ensuring it won’t exceed 10:1 to simplify the machining process. Anything deeper will require deep hole drilling.

Produce accurate parts fast

CNC rapid prototyping is among the most accurate machining solutions that eliminate human error. It has short lead times and enables easy modification so you can introduce your new products quickly to your target market. You can enjoy all these benefits at a reasonable price and in different plastics and metals, such as steel, aluminum, ABS, PP, and LDPE.
