3D printing is based on a digital , Techniques of powder metal or plastic adhesive materials, to construct the object by means of step by step a printing technology. Suitable for the production with complex structure and can not complete by the traditional processing technology, because the printing process is completely controlled by the computer, the design changes can be quickly and easily completed without additional cost, easy to test products in a short time with different versions. 3D For plastic materials, you can choose: ABS, PA, photosensitive resin; metal materials have stainless steel, titanium alloy. 3D printing is a high-tech manufacturing technology, its environmental protection and intelligence, more and more loved by the majority of customers
