1. What kinds of 3D printing materials are there
1. Metal materials (stainless steel, gold, silver, titanium, etc.).
2. Engineering plastics, including ABS plastics, ABS is the most common printing material for FDM printing technology, PLA plastic fuse, and PLA plastic fuse is a very common printing material.
3. Ceramic powder, ceramic powder material is sintered with SLS technology, glazed ceramic products can be used to hold food, and many people use ceramics to print personalized cups.
4. Photosensitive material, the transparent liver model is 3D printed with photopolymer resin as raw material. Resin is an important raw material for SLA photocuring molding technology. There are many kinds of resins, transparent and semi-solid.
5. Others, the types of 3D printing materials are far more than these. Other printing materials include cement, rock, paper, and even salt, such as: using concrete to print houses, and using wood or paper to print furniture.
Second, which is the best 3D printing material
If you want to know which 3D printing material is good, you must first have a basic understanding of various materials:
1. Engineering plastics
Engineering plastics refer to industrial plastics used as industrial parts or shell materials. , plastic with excellent hardness and anti-aging properties. Engineering plastics are the most widely used type of 3D building materials. Common ones include ABS, PC-based materials, PLA, and nylon-based materials.
2. Photosensitive resin
Photosensitive resin is ultraviolet rays (UV) resin, which is composed of polymer monomer and prepolymer, in which light is added. (UV) initiators (or photosensitizers). Under the irradiation of ultraviolet light of a certain wavelength (2500 ~ 300nm), the polymerization reaction can be immediately caused to complete the curing. Photosensitive resins are generally liquid and can be used to make high-strength, high-temperature-resistant and waterproof materials.
3. Rubber materials
Rubber materials have the characteristics of various grades of elastic materials. These materials have hardness, elongation at break, Tear and tensile strength, making it ideal for applications requiring non-slip or soft surfaces. 3D printed rubber products mainly include consumer electronics, medical equipment, as well as automotive interiors, tires, gaskets, etc.
4. Metal materials
In recent years, 3D printing technology has been gradually applied to the manufacture of actual products, among which 3D printing technology of metal materials has developed particularly rapidly . In the field of national defense, developed countries in Europe and the United States attach great importance to the development of 3D printing technology, and do not hesitate to invest heavily in research, and 3D printing metal parts has always been the focus of research and application. Metal powders used in 3D printing generally require high purity, good sphericity, narrow particle size distribution, and low oxygen content. At present, the metal powder materials used in 3D printing mainly include titanium alloy, cobalt-chromium alloy, stainless steel and aluminum alloy materials, etc. In addition, they are also used to print precious metal powder materials such as gold and silver for jewelry.
5. Ceramic materials
Ceramic materials have excellent properties such as high strength, high hardness, high temperature resistance, low density, good chemical stability, and corrosion resistance , has a wide range of applications in aerospace, automotive, biological and other industries. However, due to the hard and brittle characteristics of ceramic materials, it is particularly difficult to process and form, especially complex ceramic parts need to be formed by molds. The high cost of mold processing and long development cycle make it difficult to meet the needs of continuous product updates.
3D printing materials have their own advantages and are suitable for their own fields. Which one is better actually depends on our own cost budget, specific requirements of the work, which process is suitable, and many other factors.
