Analysis of material characteristics and application fields of CNC rapid prototyping
In the rapid prototyping industry, CNC machining is generally used for large-scale workpieces and appearance prototypes. Because the prototype processed by CNC has the advantages of large size, high precision, easy surface treatment, and beautiful appearance. CNC prototype processing materials are extensive, including ABS, PMMA, POM, PC, PA (nylon), PP, PU, acrylic (transparent materials), etc. The cost of CNC prototype is low, the processing material has the requirements of high strength, high temperature resistance, high toughness, transparency, etc. At the same time, it can produce metal prototypes such as aluminum alloy; Moreover, the surface treatment forms of CNC models are diversified, such as grinding, spraying, painting, polishing, screen printing, electroplating, etc. The effect is completely comparable to the products produced by the mold; in appearance, assembly, and function verification, the customer's final design intent can be achieved.
