4. Polymer

Two types of plastics which are widely used in polymers are ABS (Acrylonitrile Butadiene Styrene) and PLA (Poly Lactic Acid). ABS has high strength, good flexibility, machinability and high temperature resistance. It is the most commonly used thermoplastic for 3D printing. ABS material has many kinds of colors, PC material is single color, only white, but its intensity is about 60% higher than ABS material. PC-ABS material is an engineering plastic with excellent comprehensive performance, which has the toughness of ABS and the high strength and heat resistance of PC.

PLA is an environmentally friendly plastic that biodegrades into active compost. PLA's ability to resist temperature changes is weak, and it deforms when the temperature exceeds 50 °C, which restricts its development in the field of 3D printing. Polysulfone (PSU) materials are among the strongest, most corrosion-resistant and heat-resistant materials of all thermoplastics and are commonly used in the final parts and are used in the transportation, aerospace and medical industries. In addition, other new polymer materials such as nylon materials, elastic plastics, etc. have also been introduced into the field of 3D printing.

However, the existing 3D printing materials, from the price point of view, a few hundred pieces of cheap 1kg, expensive about 1 million yuan, printing costs are expensive. With the development of new materials technology, more high-performance and low-cost printing materials will appear in the future, and the development of 3D technology will continue to mature, and the cost of printed products will continue to decrease. The application of 3D printing in the medical industry, bone printing, scientific research, cultural relics protection, architectural design, manufacturing, etc. will be better developed. 3D printing technology is gradually entering people's lives, and 3D printers will become more and more civilian.
