Best 3D Printer Filament [2024 Review]

Madeline Hogan

In 3D printing, the choice of filament is as important as the design itself. 3D printers use filaments to bring objects from digital blueprints into tangible reality. They come in various types, each offering unique properties that affect the texture, strength, and flexibility of the printed items.

Whether you are 3D printing prototypes, household items, artistic sculptures, or 3D printing car parts for automobiles, the right 3D printer filament can make all the difference.

This review explores the top 3D printer filaments on the market, showing their applications, benefits, and how to select the best option for your specific needs.


What is 3D printer filament?

3D printer filament comes in the form of a thin strand of thermoplastic material, which is melted and extruded through a heated printer nozzle to build objects layer by layer. The filament allows for high precision in creating three-dimensional objects based on digital models and is available in various compositions to suit different printing needs and finish characteristics.

Each filament type offers distinct properties such as strength, flexibility, and thermal resistance, making them suitable for various applications in industries ranging from manufacturing to 3D printing prototypes.


Types of 3D Printer Filament

Let’s take a look at some different 3D printer filaments.


1. PLA



Polylactic acid (PLA) is a thermoplastic monomer made from plant-based organic sources like fermented plant starch, making it a biodegradable and environmentally friendly filament option. PLA has a relatively low melting point and usable temperatures between 180 and 230 degrees Celsius.

Although this filament has good tensile strength and stiffness, it is brittle and has poor UV resistance. However, it is generally easy to 3D print with, dimensionally stable, and does not require a heated enclosure.

Additionally, PLA does not warp easily during printing, is food-safe, and isn’t soluble in water. As a result, PLA is great for making basic prototypes using custom 3D printing and low-stress parts. It is also often used as the base material for other composite materials.

Filament Properties & Characteristics: 

  • Soluble in solvents like ethyl acetate, methyl ethyl ketone, tetrahydrofuran, and caustic soda
  • Low heat resistance but can withstand temperatures of 55 degrees Celsius
  • High surface energy
  • Bio-degradable in industrial compost environments
  • Available  in different color options
  • Comparatively low impact strength
  • Works with low extrusion temperatures


2. Tough Pro PLA+

Tough Pro PLA+


The Tough Pro PLA+ is the best type of filament to use for demanding projects that require materials with exceptional strength. Manufactured in the US from genuine NatureWorks 3D870 Ingeo PLA, Tough Pro PLA+ has a higher impact strength than standard ABS and PLA, with its heat resistance rivaling that of ABS.

Although a sustainably sourced bioplastic with an exceptional eco-profile, the Tough Pro PLA+ boasts 8.8x the impact toughness of standard PLAs all while maintaining the ease-of-printing of PLA.
