The difference between 3D printing prototype and CNC machining prototype

Make prototypes with ABS materials.What is the difference between 3D printing and CNC machining?

First, we introduce the advantages and disadvantages of the 3D printing prototype:

Is totally dependent on parts design before production process can be fulfilled, and the emergence of 3 d printers will overturn the production way of thinking, which makes the enterprise in the production of parts of time no longer consider the production process, any complex shape design can be done by 3 d printers.

3D printing can generate any shape object directly from computer graphics data without mechanical processing or mold, thus greatly reducing the production cycle and increasing productivity.

Advantages: the product process difficulty is simple, can print all kinds of difficult prototype, the prototype printing production speed is faster.

Disadvantages: the printed product has a crisp appearance and is suitable for viewing the test structure, but the appearance is more brittle and can not be tested.

Advantages and disadvantages of CNC machining prototype:

CNC Machining refers to the processing of CNC Machining tools.CNC index control machine is controlled by nc programming language.

There is a great deal of reduction in the quantity of work load, and the complex parts do not require complicated tooling.If you want to change the shape and size of the parts, you only need to modify the parts processing program, which is suitable for the development and modification of new products.

The processing quality is stable, the machining accuracy is high, the repetition precision is high, the processing requirement of the aircraft is suitable.

The production efficiency of multi-variety and small-batch production is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the optimal cutting quantity.

Advantage: because it is made of sheet metal, the quality of the product after the prototype is produced can meet the strength of the mold production and can be directly tested and assembled.Don't worry about quality.

Disadvantages: the machine tool equipment is expensive, requires the maintenance personnel to have the high level.Production processing time is a bit longer than 3D printing, so the cost of production is higher than the price of 3D printing.But the contrast can be used directly with these shortcomings can be ignored completely.
