The commonly used materials for 3D printing.
The rise and development of 3D printing technology can’t be separated from the development of 3D printing materials. The types of consumables used in different application fields are not the same, so the richness and development of materials determine whether it can be used universally. More commonly used materials are the following:
1, ABS plastics
ABS can be said to be the most commonly used printing material for FDM. Currently, there are many colors to choose from. It is a favorite printing material for consumer 3D printers, such as printing toys and creative home accessories. The ABS material is heated and melted by a 3D print nozzle. Since the nozzle needs to be solidified immediately after being ejected, the temperature of the nozzle heating is controlled to be 1° C. to 2° C. higher than the thermal melting point of the ABS material. Different ABS have different melting points and cannot be wildly fitted to nozzles that cannot adjust the temperature. This is why it is better to buy print materials from the original manufacturer.
2, PLA plastics
PLA plastic fuse can be said to be another very common printing material, especially for consumer-grade 3D printers, PLA can be degraded and is an environmentally friendly material. In general, PLA does not require a heated bed. Unlike ABS, PLA is easy to use and is more suitable for low-end 3D printers. PLA has multiple colors to choose from and also has translucent red, blue, green, and fully transparent materials. For the same reason as ABS, the versatility of PLA also needs to be improved.
Acrylic, also known as PMMA or Plexiglass, originates from English acrylic, and its chemical name is polymethyl methacrylate. Acrylic material surface finish is good, can print transparent and semitransparent products, the use of acrylic material, can be used to create a dental model for dental orthodontic treatment.
4, Nylon aluminum powder material
This material is mixed with aluminum powder in nylon powder and printed by SLS technology. The finished product has metallic luster and is often used in the printing of creative products for decorations and jewelry.
The ceramic powder is sintered using SLS. The glazed ceramic product can be used to hold food. Many people use ceramics to print personalized cups. Of course, 3D printing can't finish the high-temperature firing of ceramics. This procedure needs to be performed after printing is completed. High temperature firing.
Resin is an important raw material of SLA—Stereolithography for photo-curing molding. At present, the photosensitive resin is the most widely used material. It has many kinds of changes, transparent and semi-solid, and can be used to make intermediate design process models because of its higher molding accuracy than FDM. Can be used as a biological model or a medical model.
The real glass is currently being tested. The glass powder is printed using SLS technology. The variety of glass materials is as much as the resin and polypropylene.
8, Stainless steel
Stainless steel is hard and has a strong firmness. Stainless steel powders are sintered in 3D using SLS technology. Silver, bronze, and white colors can be used. Stainless steel can make models, modern art, and many functional and decorative items.
10, color printing and other materials
There are two cases of color printing. One is that two or more colors of the same or different materials are squeezed out of their respective nozzles. The most common is a consumer-grade FDM dual-nozzle printer that passes two or more materials. The combination to form a limited color combination. Another is to use the principle of inkjet printers, through the combination of different dyes, and adhesives mixed into the print material powder to solidify, in theory, this technology can print out "true color" 3D items. The printing material is usually selected as resin, polypropylene or ABS.
