Technical Field
The invention relates to the technical field of dart products, in particular to a novel 3D printer.
Background
A3D printer is a machine of a rapid prototyping technology, and is equipment for constructing an object by using printable materials such as powder metal or plastic and the like in a layer-by-layer printing mode on the basis of a digital model file. 3D printing is an additive manufacturing technique that manufactures 3D objects by printing layers of printed material, the basic principle being that by putting data and raw materials into a 3D printer, a program on the machine will print the product layer by layer according to the data.
