CNC processing and 3D printing, the advantages and disadvantages of the two ways

CNC and 3D printing are two commonly used processing methods for hand plate processing. Some experienced product research and development companies are familiar with the advantages and disadvantages of all kinds of hand plate processing. They have already determined the plan to use when carrying out hand plate proofing. But there are some customers to choose which way to do hand board is still very vague, so today Mingmei hand board for you to briefly introduce the advantages and disadvantages of CNC hand board and 3D printing hand board, so that we can make the right choice according to the needs of their own products

First, we compare the advantages of CNC proofing and 3 printing

CNC processing has the following advantages:

① Greatly reduce the number of tooling, processing of complex shape parts do not need complex tooling. If you want to change the shape and size of parts, only need to modify parts processing procedures, suitable for new product development and modification.

② Stable processing quality, high processing accuracy, high repetition accuracy, high precision, high strength, high quality hand plate processing requirements.

③ The production efficiency is higher under the condition of multiple varieties and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting quantity.

(4) It can process the complex surface which is difficult to be processed by conventional methods, and can even process some parts which cannot be observed.

The advantage of 3D printing is the high degree of freedom, the limitation is very low, no matter how complex the hand plate can be processed.

A product from research and development to mass production, during the hand proofing may need to go through many times, so the cost is also an aspect we have to consider. CNC processing in large parts of the price advantage, and small and complex hand plate using 3D printing is better, because it is charged by weight, has nothing to do with the complexity of the hand plate.

3 d printing in printing the whole thing is no match for the CNC processing, especially the very large pieces, with 3 d printing is generally more difficult to achieve, and CNC processing does not exist the problem, 3 d printing hand-board model belongs to the increase of material manufacturing, to do "addition" model, like toothpaste, hand-board model to pile up, and CNC machining is do subtraction
