Speaking of CNC machining, which is a different manufacturing method from 3D printing, present in working principle, cost, surface finish, and more aspects. What’s the difference between 3D printing and CNC machining? Introducing the advantages of CNC, you can have a deeper understanding of the two technologies.
3D Printing, also called additive manufacturing, is the process to make three dimensional solid objects according to a digital file. 3D printed product is created through depositing successive layers of the material. 3D printing is popular for manufacturing jewelry mold and custom gifts. The materials are diverse.
Why Choose CNC machining for your project?
1. Better surface finish
CNC machines can provide a better surface finish than 3D printer, because the material will not deform in the machining process, rigid material and cutting motion keeps the part together, there is little error or deformation. While the surface finish of 3D printing is relatively poor due to the laminated heated plastic material.
3D printing is an additive manufacturing method, what’s the difference between additive manufacturing and CNC machining?
1. Production range. The machinable range of 3D printing technologies is larger than CNC manufacturing. 3D printing has high degree of freedom, allows it to produce difficult or impossible geometries that can’t be completed with CNC.
2. Development level. CNC processing industry has a set of mature standards, including the spindle, tool interface, and control system, but there is no such an established standard in the 3D printing field.
3. Product volume. It’s difficult for 3D printing to realize super large piece manufacturing, but CNC can handle this.
4. Process type. 3D printing is an additive manufacturing method to pile up the model, while CNC is a subtract manufacturing process that continuously cuts and removes the whole raw materials.
