What are the common materials for 3D printing

2024-03-08 17:35

1. PLA material
PLA (polylactic acid) is one of the most common materials in 3D printing. It is a biodegradable material made from renewable cellulose. PLA printed objects have good surface quality and details, as well as low melting points and very low volatility. This makes PLA materials very easy to print and suitable for various applications such as prototyping, artwork, and household items.
2. ABS material
ABS (acrylonitrile butadiene styrene copolymer) is another common material in 3D printing. Compared with PLA, ABS has higher strength and heat resistance, but during the printing process, it may produce some pungent odors and harmful substances. ABS printed objects have high toughness and durability, making them suitable for manufacturing mechanical parts, toys, and models.
3. PETG material
PETG (polyethylene terephthalate) is an improved PET (polyethylene terephthalate) material. PETG has good strength and impact resistance, as well as good transparency and weather resistance. PETG material is suitable for printing objects that require high strength and durability, such as mechanical components, electrical casings, and bottles.

4. TPU material
TPU (Thermoplastic Polyurethane) is an elastic material with good elasticity and wear resistance. TPU material can print soft and elastic objects, suitable for making insoles, phone protectors, and other soft components.

5. Metal materials
In addition to plastic materials, 3D printing can also use metal materials. Metal materials form solid objects by mixing metal powders with binders and through heat treatment and sintering processes. Common metal materials include stainless steel, aluminum alloys, and titanium alloys. Metal materials have a wide range of applications and can be used to manufacture aerospace components, medical devices, and automotive components.
6. Resin materials
Resin is a liquid material that solidifies into a solid through UV or laser curing. Resin materials have excellent detail expression and surface quality, making them suitable for making precision models, jewelry, and artworks. Different types of resin materials include polyurethane resin and photosensitive resin, each with specific characteristics and applications.

 

7. Ceramic materials
In recent years, ceramic materials have been widely used in the field of 3D printing. Ceramic materials are formed by mixing ceramic powder with a binder and undergoing a sintering process to form a solid body. 3D printed ceramic products have good heat and corrosion resistance, making them suitable for making tableware, decorations, and artworks.
The above are common materials in 3D printing. Different materials have different characteristics and applications, and suitable materials can be selected for printing according to needs and requirements. With the continuous advancement of technology, new materials are also constantly emerging, bringing more possibilities and opportunities to the 3D printing industry. Whether creating prototypes or manufacturing customized products, 3D printing materials are important tools for realizing imagination.
