The consumables for 3D printers are PLA, ABS, photosensitive resin (liquid), wax-based materials, nylon powder, gypsum-like powder, metal powder (including stainless steel, titanium alloy iron-nickel alloy, cobalt-chromium alloy, etc.). There are many kinds of materials such as photosensitive resin and wax-based materials. The melting point, hardness and strength of each material are different. Different 3D printers use different materials for printing. Generally speaking, the printing cost of 3D printers is generally compared. high. In general, FDM technology uses more PLA and ABS; photocurable molding uses more photosensitive resin or wax-based materials; nylon powder and metal powder use laser sintering more; in general, it is additive manufacture
3D printing details
3d printing technology is a kind of rapid prototyping technology. It uses a bondable material such as powdered metal or plastic to construct a zero object by layer-by-layer multi-layer printing. Mold manufacturing and industrial design often use this technology to build models, and now they are developing in the direction of product manufacturing, forming "direct digital manufacturing."
2. Developing history:
3d printing technology originated in the United States in the mid to late 1980s, when 3D printers were very large and expensive. After more than 20 years of development, the technology has matured and the machines have gradually become smaller. Since the 21st century, the sales of 3D printers have gradually expanded, and prices have begun to decline. From the initial large-scale industrial users such as manufacturing, they have gradually penetrated into various industries. In recent years, it has begun to expand into consumer sectors such as individuals and families. Nowadays, the business model of 3D printing has gradually matured and the industry chain has basically taken shape.
At present, 3D printing has been widely used in military, aerospace, medical, construction, automotive, electronics, clothing, jewelry and other fields.
3d printing technology can quickly produce high-end customized products. 3d printing technology can produce almost any complex parts without the use of molds and tools, greatly improving production efficiency and manufacturing flexibility.
