Unique advantages of 3D printing To quote:3D printing is essentially a stack of layers, the idea of additive manufacturing. Many technical methods borrow this thinking, ranging from architectural production to nanometer accumulation. However, mainstream 3D printing is mainly concentrated in the manu

Some cold knowledge of 3D printing 3d printing essentially melts the thermoplastic, sprays out more delicate "threads" at the nozzle, and then sprays layer upwards by layer, layer by layer. In essence, 3d printing is just Combining layers of "planes" to make them three-dimensional. But this is
