3D Printing Technology Development Factors
Shenzhen Qihang Electronics Co.,Ltd | Updated: Nov 01, 2018

At present, there are two main factors that restrict the development of 3D printing technology, printing materials and equipment. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, photosensitive materials and ceramic materials. Its form is generally powdery, silky, lamellar, liquid


Engineering plastics are excellent in strength, hardness, impact resistance, resistance and aging resistance. The photosensitive resin is composed of a polymer monomer and a prepolymer, and can immediately cause polymerization to complete curing under irradiation of ultraviolet light of a certain wavelength.a rubber-based material with various levels of elasticity, hardness, elongation at break, tear resistance and tensile strength.It is ideal for applications requiring a non-slip or soft surface. Ceramic materials with excellent properties such as high strength, high hardness, high temperature resistance, low density, good chemical stability and corrosion resistance,It has a wide range of applications in the aerospace, automotive, and biological industries. Metal materials, 3D printed metal powder materials mainly include titanium alloy, stainless steel, aluminum alloy,Superalloys, etc., in addition to precious metal printing materials. Titanium alloys are of particular importance among all materials because of their low density and high strength.Corrosion resistant, high melting point, ideal aerospace materials, especially suitable for laser 3D printing technology.Stainless steel is currently the cheapest and cheapest 3D printing material, and is often used as 3D printing for jewelry, functional components, and the like. Superalloys because of their high strength,Stable chemical properties, difficult to shape processing and high cost of traditional processing techniques have become the main 3D printing materials for aerospace applications.
