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.

CNC prototype common processing material performance

ABS prototype material characteristics: Temperature tolerance range 70-80 ℃.
  Material properties: Average strength and toughness, generally suitable for the production of prototype electrical appliances

PMMA Acrylic prototype material characteristics: PMMA sub-acrylic temperature tolerance range of 60-80 ℃.
Material properties: High transparency, poor strength and toughness, suitable for prototype production of liquid crystal shells for electrical appliances

The temperature tolerance range of POM Saigang prototype material is 90-110 ℃.
  Material properties: Good strength, toughness and hardness, mainly suitable for prototype production of mechanical gear rotating parts

PA nylon prototype material temperature tolerance range 100-130 ℃.
Material properties: Good strength, toughness and hardness, not easy to be polished

PC prototype material temperature tolerance range 90-110 ℃.
Material properties: Translucent, general hardness, strength, toughness, suitable for prototype production of high-heated parts in electric rice cookers and irons

The temperature tolerance range of Bakelite prototype material is 150-180 ℃.
Material properties: The strength and toughness are inferior to ABS, suitable for prototyping high-heat parts
