Talking about the difference between 3D printing and CNC machining

Shenzhen Nobo Intelligent Manufacturing Technology Co., Ltd., a professional prototype machining manufacturer, started with prototypes. After years of experience accumulation, it has gradually become a project support service including parts manufacturing and machining. It has a ten-year history. work experience. Specializing in Shouban and CNC machining, plastic and metal parts machining, injection mold, and formal mold machining.


What is CNC machining?

Numerical Control Machining refers to a process method for machining parts on CNC machine tools. The process rules of CNC machine tool processing and traditional machine tool processing are generally consistent, but there have also been significant changes. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of a variable variety of parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated machining. The controlled actions of the machine tool roughly include the start and stop of the machine tool; the start and stop of the spindle, the change of the rotation direction and speed; the direction, speed, and mode of the feed movement; the selection of the tool, the compensation of the length and radius; the replacement of the tool, the cooling Opening and closing of liquid.



Prototype machining mainly includes CNC machining, 3D printing, complex mold, rapid mold, etc. So today, Noble will tell you the difference between CNC machining and 3D printing. First of all, you need to know that 3D printing is an additive technology, and CNC machining is a subtractive technology, so they are very different in terms of materials.

1. Differences in machining materials

The materials for 3D printing mainly include liquid resin, nylon powder, metal powder, etc. These three different materials occupy most of the industrial 3D printing market, and the materials used for CNC machining are all pieces of plates, and the CNC machine There are more material choices for machining than 3D printing. General hardware and plastic sheets can be CNC machined, and the density of molded parts is better than 3D printing.

2. Different machining accuracy

The prototypes printed by 3D are relatively rough and have low precision; while the prototypes machined by CNC have high precision, which can generally reach ten wires. The metal prototype machining by the high-speed drilling and tapping center can be achieved in terms of precision.

3. The machining range is different

The live chat of 3D printing machining is mainly plastic materials, such as photosensitive resin, ABS, etc., and its processing range is also relatively limited, generally, no more than 600mm, if it is larger than this size, it needs to be disassembled to print, printing such a large prototype. The cost of CNC machining is also very high, and CNC machining materials are relatively wide, almost all plastics and metals can be processed, and the stroke is relatively large, known to be more than 1 meter, like a gantry machine tool, the processing range can even be the whole piece Processed to a range of two to three meters.
