3D printing and CNC machining are relatively common production processes in the field of precision machining. There are similarities and differences between the two. For example, CNC machining is suitable for mass production. It can create many products in less time than 3D printing takes hours to create one product. Compared with 3D printing, what are the advantages of CNC machining? Next, let me give you a brief introduction.

1. Advantages of surface treatment

CNC machines provide a better surface finish than 3D printing because the material does not deform during machining. The rigid material and cutting action keep the product together with less chance of errors or deformation. The surface finish of 3D printing is poor. The material bends, twists or twists because the material is layered heated plastic.

2. Prototype integrity has been improved

CNC machines do not heat the material and transform it. The material stays stronger and has better structural integrity than a 3D printer, which must heat the material to build the intended product. 3D printers may also require foreign objects to be added to the mix in order to make prototypes, while CNC machines do not.

3. Prototyping becomes easier

CNC machines are better suited for prototypes that can withstand structural testing because they carve designs out of the material. They can also build prototypes using the exact materials that will be used to make the final product.

Structural testing and changes will be more accurate since they use the same material. This can speed up the production process because the changes will be in the design rather than the material. 3D printers do not create structurally strong prototypes, so they cannot be physically tested.

4. Price and trading volume do not represent price

3D printing costs depend on the volume of material required. The final product quantity does not determine the price of a CNC machine. For larger orders, 3D printing is not cost-effective, which is where CNC machines thrive.

5. The level of tolerance rises

CNC machines are more precise, so parts have better tolerances than 3D printers. Prototypes that have shafts or connections to other parts will be of higher quality and more likely to fit the other parts due to the level of tolerance.

6. Quality is beneficial to CNC

Larger layers are faster for 3D printers, but not as high quality as smaller layers. If you need a prototype, you have the option of getting it quickly but at slightly lower quality, or waiting longer to get the best quality prototype your printer can offer. CNC machines allow you to choose the resolution of your items. They are available in varying qualities in a short amount of time, making them ideal for quick builds and instant test results.

7. Reduce costs

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

To sum up, CNC processing has more advantages than 3D printing. If you want to know more about CNC processing, please call Xiehe Processing Factory.
