What are the advantages of cnc machining compared to 3D printing?

Many people may not know much about these two, but in our industrial industry, the scope of application is still very wide. 3D printing and cnc machining are the more common production processes in the field of precision machining today. There are similarities and differences. Then let's find out what are the advantages of cnc processing compared to 3D printing?

First, surface treatment advantages

CNC machine tools provide a better surface finish than 3D printing because the material does not deform during processing. The rigid material and cutting action keep the product together and there is less chance of errors or deformation. The surface finish of 3D printing is poor. The material is bent, twisted or twisted because the material is a layered heated plastic.

Improved prototype integrity

The CNC machine does not heat the material and transforms it. The materials remain stronger and have better structural integrity than 3D printers, and 3D printers must heat the materials to build the intended product. 3D printers may also need to add foreign objects to the mixture to make prototypes, while CNC machines do not.

Prototyping becomes easier

CNC machine tools are more suitable for prototypes that can withstand structural tests because they sculpt designs from materials. They can also build prototypes using the exact materials that will be used to make the final product. Structural tests and changes will be more accurate because they use the same materials. This can speed up the production process because the change will be design, not material. 3D printers do not make prototypes with structural strength, so they cannot be physically tested.

4. Price and trading volume do not represent price

The cost of 3D printing depends on the volume of material required. The final product quantity does not determine the price of CNC machine tools. For larger orders, 3D printing is not cost-effective, and this is where CNC machine tools are booming.

5. Rising tolerance

CNC machine tools have higher precision, so parts have better tolerances than 3D printers. Due to tolerance levels, prototypes with shafts or connections to other components will have higher quality and are more likely to fit other components.

6, quality is good for CNC

Larger layers of 3D printers are faster, but not as high quality as smaller layers. If you need a prototype, you can choose to get it quickly but with slightly lower quality, or wait longer to get the best quality prototype that the printer can provide. The CNC machine lets you choose the resolution of your items. They can provide different qualities in a short period of time, making them ideal for rapid construction and instant test results.

Seven, reduce costs

If you can choose which manufacturing method to use for your product, CNC machining is usually cheaper than 3D printing.

The above points are the advantages of cnc machining compared to 3D printing. Today we will talk about it first. For more information, please visit the cnc machining shop website in Dongguan for more details.
