when making prototype proofing, choose whether CNC machining is good or 3D printing processing is good, for some people who don't know much about the industry, it's not good to choose. In fact, it is not very difficult. To put it bluntly, as long as you know enough about the two processes, you can choose the appropriate processing method according to the features of the prototype you want to do. Because whether it is CNC machining or 3D printing prototype machining, it depends on the size of the product, the material and the corresponding budget.

Proofing can be processed more by CNC machining material, almost all plastic and metal materials are included, and the processing accuracy is relatively high. More importantly, the size of the processing is much larger than that of 3d printing. Most of the CNC machining trips of prototype manufacturers can reach about 1 m, and some manufacturers can reach 1500. The extension model introduced a batch of new equipment in 2016, with a processing stroke of 2000, which can process a large prototype. The prototype made in this way is relatively stable and has high strength.

If prototype proofing is carried out by 3d printing, it takes only a few hours to a dozen hours to complete the production of parts with very complex structures at one time, but 3d printing also has some shortcomings, and the materials processed are limited, mainly light sensitive, ABS, nylon, etc. , and the performance (Strength, high temperature resistance)It is not as good as CNC machining. The cost of 3d printing prototypes is calculated by weight, about a few dollars a gram, so too much is not suitable for 3d printing, which is not cost-effective.

to sum up, when making prototype proofing, the prototype with large size and simple shape is better to use CNC machining, while the small and complex prototype is more cost-effective to use 3d printing. If you have special requirements for the performance of the prototype, it is better to use CNC machining.
