What is 3D Printer Filament

3D printer filament is a thermoplastic material used in 3D printing. It comes in the form of a thin, flexible strand that is fed into a 3D printer, melted, and then extruded layer by layer to build a three-dimensional object.

Raw Material of 3D Printer Filament

Currently, 3D printer consumables are in the form of solid round filaments, with main raw materials including ABS, PLA, PVA, HIPS, PC, PA, TPU, and others. The product diameters range from 1.75mm to 3.0mm.

PLA and ABS are the two most commonly used materials. With the promotion and popularization of 3D printing technology, the development and application of specialized materials with superior performance, such as PEEK and PVA, are gradually advancing, in addition to the conventional PLA and ABS materials.


ABS (Acrylonitrile Butadiene Styrene) is a common thermoplastic polymer known for its toughness, impact resistance, and ability to be easily molded or extruded.

Regardless of the type of extruder used, the material will extrude smoothly without concerns about clogging or solidification. It’s very suitable for 3D printing functional parts that require durability and impact resistance.

ABS plastic presents challenges in 3D printing due to its tendency to shrink when cooling, causing parts to detach from the print bed and potentially fail, especially with tall prints. This material also tends to warp, impacting adhesion and dimensional precision. However, with meticulous printer calibration, such as using a heated build platform and maintaining a controlled printing environment, ABS can effectively produce durable and impact-resistant functional parts.

An extrusion line can alleviate challenges in ABS plastic processing for 3D printing by ensuring precise control over filament production, resulting in consistent diameter and properties that reduce warping and enhance print bed adhesion. Customizable filament characteristics and optimized production parameters further improve printing reliability and quality.


PLA is a semi-crystalline polymer with a melting temperature between 170-180°C, lower than ABS’s 200-260°C. This lower melting point eliminates the need for a heated tray and enclosed printing chamber. PLA offers good performance with high printing speed and sharp edges if properly cooled, and the resulting parts have low deformability.

However, PLA has a higher viscosity than other thermoplastics, which can cause clogging if not handled carefully. PLA filaments have a shelf life of at least one year when stored between 15 to 25°C. Compared to ABS, PLA lacks the same strength and flexibility but is less prone to warping. It is recommended for parts without high mechanical complexity due to its ease of use.

3D printer filament extrusion line can address several issues associated with PLA. It ensures consistent filament diameter and quality, reducing the risk of clogging due to high viscosity. While PLA still lacks the strength and flexibility of ABS, precise extrusion can maximize its performance.


PEEK combines excellent mechanical properties, chemical resistance, wear, fatigue, and creep resistance, with high-temperature stability. It also offers good combustion resistance and dielectric performance.

When 3D printing with PEEK, controlling the crystallization process is crucial, as it affects the material’s density and overall print quality. To successfully print with PEEK, a 3D printer needs to maintain high and stable temperatures: an extruder reaching 400°C, a chamber heated to 120°C, and a build plate capable of 230°C. These conditions prevent warping and ensure proper part release.
