How does 3D printing print a rapid prototyping prototype?

The 3D printing accuracy refers to the accuracy of the comparison between the printed object and the model, which is related to the layer thickness setting, positioning accuracy and spot accuracy, and may also be related to the size of the printed model and the completion time of the model.

3D printing can directly generate objects of any shape from computer graphics data without machining or molds, which greatly shortens the production cycle of products and improves productivity.

The process of 3D printing is as follows:

Under the guidance of the instructions in the design documents, the 3D printer first sprays solid powder or molten liquid material to solidify it into a special plane thin layer.

The cost of polymer production by traditional injection molding method has been relatively low, while 3D printing prototype can achieve faster, lower cost, and high precision, and the prospect of 3D printing prototype is very broad. In recent years, 3D printing can be described as a booming scene

After the first layer is solidified, the 3D printer print head returns to form another thin layer outside the first layer.

After the second layer of solid is liquefied, the print head returns again and another thin layer is formed outside the second layer. In this way, the thin layer finally accumulates into a three-dimensional object.

Unlike traditional manufacturing machines, 3D printers create objects by cutting or molding. The method of forming physical objects by stacking layers expands the scope of digital concepts from a physical perspective.

3D printer is the preferred processing equipment for shape design requiring precise internal concave or interlocking parts, which can be realized in the physical world.
