Rapid prototyping technology breaks through the traditional part processing mode of "blank/cutting/finished product" and pioneers the production of parts without cutting tools. It is an unprecedented thin layer superposition processing method. Compared with traditional cutting methods, rapid prototyping has the following advantages:

1. Free-form surface and more complex parts, such as grooves, shoulders and hollow parts, can be quickly manufactured. The complexity of parts and the production batch have little to do with the manufacturing cost, which greatly reduces the development cost and cycle of new products.

   2. It belongs to non-contact processing. It does not need the tools and fixtures necessary for machine tool cutting, and has no influence of tool wear and cutting force.

   3. No vibration, noise and cutting waste.

   4. Fully automatic production can be realized.

   5. Processing efficiency is high, and the solid model and die of the product can be produced quickly.
