Commonly used materials for 3D printing are nylon fiberglass, durable nylon materials, gypsum materials, aluminum materials, titanium alloys, stainless steel, silver-plated, gold-plated, and rubber-like materials.
Many different technologies exist for 3D printing. They differ in the way the materials are available and are built in different layers to create parts.
The ABS material has become the engineering plastic of choice for 3D printing via fused deposition because of its good hot-melt, impact strength. Currently, ABS is mainly used after being pre-fabricated into filaments and powdered, and its applications cover almost all daily necessities, engineering supplies and some mechanical supplies.PA is strong and flexible at the same time, so it can be directly utilized to create equipment parts by 3D printing.
What are the materials for 3d printing?
The materials for 3d printing are: photosensitive resin composites, polymer powder materials, paraffin powder materials, ceramic powder materials, fused wire materials, FDM ceramic materials, wood-plastic composites, and FDM support materials.
The most commonly used materials are photosensitive resin, PLA,, ABS, nylon and stainless steel.
Photosensitive resin is resin, composed of polymer monomer and prepolymer, which is added with photoinitiator. In a certain wavelength of ultraviolet light irradiation can immediately cause polymerization reaction to complete curing. Photosensitive resins are generally liquid and can be used to make high-strength, high-temperature resistant, waterproof materials.
And ceramic materials with high strength, high hardness, high temperature, low density, good chemical stability, corrosion resistance and other excellent characteristics, in the aerospace, automotive, biological and other industries have a wide range of applications. However, due to the hard and brittle characteristics of ceramic materials make its processing and forming particularly difficult, especially complex ceramic parts need to be formed through the mold. Mold processing costs are high, the development cycle is long, it is difficult to meet the demand for continuous updating of products.

ABS plastic
ABS is arguably the most commonly used printing material for FDM. Currently available in a wide range of colors, it is the most popular printing material for consumer 3D printer users, such as printing many Lego-type toys and making many creative home décor items.ABS material is usually filament coils, which are heated and melted through a 3D printing nozzle for printing. Since the nozzle needs to cure immediately after spraying, the heating temperature of the nozzle is controlled to be 1°C to 2°C higher than the hot melting point of the ABS material. Different ABS cannot be matched with nozzles that cannot be adjusted in temperature due to their different melting points. This is why it is best to purchase printing materials from the original manufacturer. Metal Processing WeChat, the content is good and worth following.
PLA plastic
Plastic fuse can be another very commonly used printing material, especially for consumer 3D printers.PLA is biodegradable, making it an environmentally friendly material.PLA does not generally require a heated bed, unlike ABS, so PLA is more usable and better suited for lower-end 3D printers.PLA is available in a wide range of colors, translucent red , blue, green and fully transparent materials. For the same reason as ABS, PLA's versatility leaves something to be desired.
Alec Acrylic Material
Alec material has a good surface finish and can print transparent and translucent products. Currently, Alec material can be used to make dental models for orthodontic treatment.
Nylon Aluminum Powder Material
This material is mixed with aluminum powder in nylon powder and printed by SLS technology. Its finished product has a metallic luster and is often used for printing of decorations, jewelry and other creative products.
Ceramics-Ceramics
Ceramic powder is sintered by SLS. Glazed ceramic products can be used to serve food. Many people use ceramics to print personalized mugs. Of course, 3D printing cannot accomplish the high temperature firing of ceramics. This procedure now requires high temperature firing after printing.
Resin - Resin
Resin is an important raw material for light-curing rapid prototyping. It comes in many variations, including transparent and semi-solid forms, and can be used to model intermediate design processes. Because it can be molded with higher precision than FDM, it can be used as biological or medical models.

Other Metals-Silver, Gold, and Titanium
These metallic materials are sintered from SLS powder; gold and silver can be used to print jewelry, and titanium is a material often used by high-end 3D printers to print parts on aerospace vehicles.
Color printing and other materials
There are two types of color printing, one in which two or more colors of the same or different materials are extruded from their respective nozzles, most commonly used in consumer-grade FDM dual-nozzle printers, where a finite number of shades are created by combining two or more materials. The other utilizes the principle of inkjet printers, where a combination of different dyes are mixed with a binder and injected into the print material powder for curing. Theoretically, this technology can print 3D objects in "true color". The printing materials are usually resin, polypropylene, or ABS, and the most established technology for "full-color" printing is 3Dsystem, followed by Israel's Objet.
Other printing materials include concrete, rock, paper, and even salt, to name just a few of the current research applications. Printing a house out of concrete, for example, is already being developed by a company in the Netherlands. Initial experiments could print small models or prefabricated parts, and there has also been research into printing furniture from wood panels or paper, especially newspapers where the paper can be recycled. Very promising.
We've covered the materials commonly used and available for 3D printing, and materials for 3D printing are constantly evolving. For example, Israel's Objet produces a wide range of consumer and industrial-grade printers, but Objet focuses more on the development of printing materials, and each year introduces printing materials for different industries, such as medical materials. Also, it is important to recognize that 3D printing materials are newly developed and customized specifically for 3D printing. Whether it is FDM or SLA or SLS technology, the material requirements are very high, and 3D printing materials are still relatively expensive. The versatility of materials is a problem that needs to be solved.Objet introduces several new materials every year, but they can only be applied to printers produced by Objet. Versatility of materials has now been a breakthrough for consumer printers, but materials for industrial and high-end printers remain exclusive.
