3D printing and CNC precision machining, which are more common production processes in the field of precision machining today, have similarities and differences, such as CNC machining is suitable for mass production. It can create many products in a much shorter period of time, 3D printing takes hours to create a product. What advantages does CNC precision machining plant have over 3D printing? The main points are as follows.
I. Surface Treatment Advantages
CNC machines provide a better surface finish than 3D printing because the material is not shaped during the process. Rigid material and cutting action keep the product together and there is less chance of error or distortion.3D printing has a poorer surface finish. The material bends, twists or distorts because the material is layered with heated plastic.
Second, prototype integrity is improved
CNC machines do not heat the material and modify it. The material stays stronger and has better structural integrity than 3D printers, which must heat the material to build the intended product.3D printers may also need to add foreign matter to the mixture to make a prototype, whereas CNC machines do not.

Third, prototyping becomes easier
CNC machines are better suited for prototypes that can withstand structural testing because they carve out designs from materials. They can also build the prototype 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 changes will be to the design and not to the material. 3-D printers do not make prototypes with structural strength, so they cannot be physically tested.
Fourth, price and volume are not indicative of price
The cost of 3D printing depends on the volume of material required. The volume of the final product does not determine the price of the CNC machine. For larger orders, 3D printing is not cost-effective, which is exactly what happens when CNC machines thrive.
V. Rising tolerance levels
CNC machine tools are more accurate, so parts have better tolerances than 3D printers. Due to the tolerance levels, prototypes with shafts or connections to other parts will be of higher quality and more likely to fit other parts.
Sixth, quality favors CNC
The larger layers of a 3D printer are faster, but not as high quality as the smaller layers. If you need a prototype, you have the option of getting it quickly but at a slightly lower quality, or waiting longer to get the best quality prototype the printer can offer.CNC machines allow you to choose the resolution of the item. They can deliver different qualities in a short amount of time, making them ideal for quick builds and instant test results.
VII. Reducing Costs
If you have a choice of which manufacturing method to use for your product, CNC machining is usually cheaper than 3D printing. Overall, these are seven advantages of CNC precision machining over 3D printing in the field of precision machining.
