What processing method is used for large prototype

when making a prototype, the situation of making a large prototype cannot be avoided, and many prototype factories are willing to take orders like this. There are several kinds of processing methods in the general good prototype processing factory, which are more commonly used: CNC machining and 3D printing. So when processing large prototype, what kind of processing method will be better?

1, 3D printing

3D printing is a relatively fast processing method in the prototype processing factory, however, it is generally used to make products that are not too large, because the larger the volume of the product, the slower it will print.

2, CNC machining

CNC processing will be slower than 3D printing, it is written by the programmer to control the 3D data into the programming language of the CNC machining center, and then moves according to the set program to remove the excess parts of the material, thus obtaining the prototype model. CNC machining large prototype is generally more cost-effective, and the accuracy of processing is also relatively high. The five-axis machine is used for processing the model, and the accuracy can reach 0. 01mm.

The General large-scale prototype will be made by CNC machining, because of the 3D printing production, the larger products need to be disassembled to do so. The effect is not so good, mainly expensive.

cnc prototype machining 3d printing stocks is generally used to rapid prototyping aluminium.
