3D printing CNC machining are common production processes in the field of precision machining. They have similarities differences. For example, CNC machining is suitable for mass production. It can create many products in a shorter time, 3D printing takes several hours to create a product. Compared with 3D printing, what are the advantages of CNC machining? There are mainly the following points:

1、 Advantages of surface treatment

CNC machines provide a better surface finish than 3D printing because the material does deform during processing. Rigid material cutting action keep the product together, there is less chance of error deformation. The surface finish of 3D printing is poor. The material bends, twists, twists because the material is laminated heated plastic.

Two, the integrity of the prototype has been improved

The numerical control machine does heat the material carries on the transformation. Compared with the 3D printer, the material remains stronger has better structural integrity. The 3D printer must heat the material to build the expected product. 3D printers may also need to add foreign material to the mix to make prototypes, whereas CNC machines do .

3、 Prototyping becomes easier

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

Structural tests changes will be more accurate because they use the same material. This can speed up the production process, as the change will be in design rather than in materials. 3D printers do build prototypes with structural strength, so they cannot be physically tested.

4、 Price volume do represent price

The cost of 3D printing depends on the volume of material required. The final product quantity does determine the price of CNC machine tools. For larger orders, 3D printing is cost-effective, which is the booming situation of CNC machine tools.

5、 Tolerance level rises

CNC machine tools have higher accuracy, so parts have better tolerance than 3D printers. Due to the tolerance level, prototypes with shafts connected to other parts will have higher quality are more likely to fit other parts.

6、 Quality is good for CNC

The larger layers of 3D printers are faster, but as high quality as the smaller layers. If you need a prototype, you can choose to get it quickly but with slightly poor quality, wait longer to get a prototype of the quality the printer can provide. CNC machine allows you to choose the resolution of the item. They can provide different quality in a short period of time, making them ideal for fast build immediate test results.

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

In general, CNC machining has seven advantages over 3D printing in the field of precision machining.
