With the development of the industrial design industry, the metal rapid prototype has become the preferred choice for the majority of designers. The metal rapid prototype consists of raw materials mainly aluminum alloy, stainless steel, magnesium alloy, titanium alloy, zinc alloy, copper and other materials, through the CNC Machining Processed, combined with anodizing, electroplating, power costing, polishing and other surface treatments, the metal rapid prototype more toward the high-quality industrial products with high quality requirements, good performance and beautiful appearance. For more information on the processing of metal materials and the surface treatment of the rapid prototype.
