What are the important factors affecting 3D printing in mass production?

          The factors that affect the mass production of 3D printing are, first of all, the materials. Can the material diversity and functionality meet the requirements of printed materials?

          For example, if you print a leather seat, you can directly print the leather texture by 3D printing. Therefore, the seat requires high impact resistance. Therefore, the printed engineering materials must first have impact resistance.

          In addition, the material also needs to be resistant to high temperatures and extreme cold. In addition, it needs to have ultra-high strength, ultra-high toughness, impact resistance, and corrosion resistance. Because metallic and non-metallic printing materials are very limited, the development of materials science is also a very important area in the development of 3D printing.
          The next thing that affects printed 3D printing is the cost of printing. If 3D printing is expensive, many people can't afford it. That means the costs are too high.

          The third is design. Although 3D design is not difficult, the change of concept is still difficult. Many engineers on the production line may not necessarily have the concept of using 3D printing.

          The fourth is the repeatability of printing. The big advantage of mechanical manufacturing is that it can be produced in large quantities, and the tolerance accuracy between each batch can be controlled strictly. At present, the accuracy control of 3D printing is relatively lacking,  Therefore, it is needed to be further developed.
