3D printer filaments

What are 3D filaments and why is the right choice important

3D printer filaments are plastic threads that serve as "ink" for 3D printing. During printing, the filament is heated and extruded layer by layer, forming a three-dimensional object. The right choice of 3D printer filament is crucial because the material determines the strength, flexibility, and appearance of the printed model.

The different 3D filaments have unique properties, so the choice depends on the specific project. Some materials are stronger and heat-resistant, while others are easier to print or are flexible. If you choose the wrong material, the final result may turn out to be brittle, deformed, or of unsatisfactory quality.

Types of filaments for 3D printer

There are several main types of filament, each with its own advantages and applications. Here is an overview of the most popular materials we offer:

PLA (polylactic acid)

PLA is the most widely used 3D filament. It is easy to print because it is extruded at a lower temperature and hardly shrinks when cooling. PLA is an excellent choice for beginners, as well as for decorative items, prototypes, and educational projects. Models printed with PLA have good stiffness and detail, but are not very resistant to high temperatures (softening above ~50°C) and extreme loads.

ABS (acrylonitrile-butadiene-styrene)

ABS is a strong and durable filament suitable for functional parts. ABS prints withstand higher temperatures (up to ~80°C) and impacts, making it ideal for mechanical details and housings. Unlike PLA, ABS requires a heated bed and good ventilation during printing (due to the fumes released). Printing with ABS is more challenging, but the end result is a durable model that can be smoothed with acetone for a better appearance.

PETG (polyethylene terephthalate glycol)

PETG combines the advantages of PLA and ABS. This material is stronger and less brittle than PLA, and easier to print than ABS. PETG has excellent layer adhesion and low shrinkage, which reduces the risk of warping. It is suitable for making durable prototypes, functional parts, containers, and products that will be subjected to moderate loads or even outdoors. It prints best with a slightly heated bed (~70°C) and at a moderate nozzle temperature (~230°C). Compared to PLA, PETG is slightly more viscous, so fine "strings" may appear during printing, but with the right settings, this is minimized.

TPU (thermoplastic polyurethane)

TPU is a flexible filament, similar to rubber in properties. The details printed with TPU can bend and twist without breaking, making it excellent for cases, seals, or other elastic elements. TPU is printed at a lower speed and moderate temperature (~210°C). The best results are achieved with printers that have direct filament feeding, but many standard models can also print with TPU after proper setup. In return for the effort, you get unique flexible objects that other plastics cannot create.

Brands of filaments that we offer

The quality of the filament also depends on its manufacturer. In our catalog, you will find threads from proven filament brands with an established reputation:

• Polymaker – an innovative manufacturer with high quality control, providing consistent results in printing.
• eSUN – a popular brand with a wide selection and affordable prices, known for its reliable filaments for all kinds of applications.
