What is the difference between a 3D printer and a CNC lathe?

The CNC machining center cuts excess material, and the 3D printer accumulates the required material.

The biggest difference between the two is that they are opposite.

The following is the principle of 3D printer: 3D printing is a form of additive manufacturing technology, in which three-dimensional objects are created through continuous physical layers.

Compared with other additive manufacturing technologies, 3D printers have the advantages of high speed, low price, and high ease of use.

A 3D printer is a device that can "print" real 3D objects. Functionally, it is the same as laser molding technology. It uses layered processing and superposition molding, that is, by adding material layer by layer to generate a 3D entity. It is different from traditional material removal processing.

The technology is completely different.

Calling it a "printer" refers to its technical principle, because the layered processing process is very similar to inkjet printing.

As this technology continues to advance, we have been able to produce 3D models that closely match the look, feel and functionality of the prototype.

To put it simply, 3D printing is the reverse process of tomography. Tomography is to "cut" something into countless superimposed pieces. 3D printing is to print piece by piece and then superimpose them together to become a three-dimensional object.

Using a 3D printer is like printing a letter: tap the "Print" button on your computer screen, and a digital file is transferred to an inkjet printer, which sprays a layer of ink onto the surface of the paper to create an image.

2D image.

During 3D printing, the software completes a series of digital slices through computer-aided design technology (CAD) and transmits the information of these slices to the 3D printer, which stacks successive thin layers until a solid object is formed.

The biggest difference between 3D printers and traditional printers is that the "ink" they use is real raw materials.
