Using a 3D printer opens the door to a universe of possibilities. There are many choices of filament feedstock for 3D printers.
Filaments for 3D printers: from every day to truly creative
There is one universal need that connects the various applications of a 3D printer: filament. Of the many filament (filament) feedstock options for 3D printers, here we look at common "everyday printing" filaments such as PLA and PETG, as well as fancy types that allow you to print really creatively (also often referred to as "exotics").
In addition to the common thermoplastics that include the usual types of 3D printer filament (such as the aforementioned PLA and PETG), 3D printer filament can or consists of nylon, polycarbonate, carbon fiber, polypropylene, and many others! There are even special composite materials that can conduct electricity or glow in the dark!
With this variety, it's easier than ever to create functional, visually expressive, and high-performance prints from a variety of exciting plastics. With this in mind, we present our buyer's guide for the 3D printer filament. Explore the four sections and you'll find a total of 30 filament material categories:

- industrial high-temperature.
In the world of 3D printing, there is a wide variety of filaments available, each with its unique properties and characteristics. These filaments serve as the building blocks for creating objects through additive manufacturing. Let's explore some of the most common types:
PLA (Polylactic Acid): PLA is a popular filament known for its ease of use and eco-friendly nature. It's derived from renewable resources like cornstarch or sugarcane and is biodegradable. PLA is widely used for prototyping, hobbyist projects, and models due to its low warping and good dimensional accuracy.
ABS (Acrylonitrile Butadiene Styrene): ABS is a tough and durable filament known for its strength and impact resistance. It's commonly used in engineering applications, functional parts, and automotive components. ABS requires a heated print bed to minimize warping during printing.
PETG (Polyethylene Terephthalate Glycol): PETG is a versatile filament that combines the best properties of PLA and ABS. It's known for its durability, flexibility, and chemical resistance. PETG is often used for mechanical parts, containers, and objects that require strength and transparency.
TPU (Thermoplastic Polyurethane): TPU is a flexible filament that offers elasticity and rubber-like properties. It's used for creating objects that need to be bendable or have impact absorption, such as phone cases, footwear, and prosthetics.
Nylon: Nylon filaments are known for their high strength, durability, and resistance to impact. They are commonly used in industrial applications, functional prototypes, and parts that require toughness. Nylon filaments may require a heated print bed and careful printing settings.
PC (Polycarbonate): PC filaments are known for their excellent heat resistance, high strength, and optical clarity. They are often used in applications where thermal resistance and toughness are essential, such as automotive components, electronic enclosures, and safety glasses.
Wood-filled Filaments: These filaments combine a polymer base, like PLA or ABS, with fine wood particles. They create objects with a wooden appearance and can be sanded and stained like real wood. Wood-filled filaments are popular in artistic and decorative applications.
Metal-filled Filaments: Metal-filled filaments, such as brass, copper, or stainless steel, contain fine metal particles mixed with a polymer base. They allow for the creation of objects with a metallic appearance and feel. Metal-filled filaments are often used for jewelry, sculptures, and functional parts.
These are just a few examples of the wide range of filaments available for 3D printing. Each filament has its unique properties, advantages, and printing requirements. It's always important to check the specifications and recommendations for your specific 3D printer to ensure optimal results.
