Guide to 3D Printing Filament! PLA ABS PETG TPU and more!

Choosing filament starts with the kind of object you want to make. A decorative figurine, a flexible phone case, and a mechanical part call for different properties.

In this video, I introduce PLA, ABS, TPU, PETG, nylon, and polycarbonate, explaining the characteristics and example uses that distinguish them. Here’s a quick guide to the materials covered.

PLA: prototypes and decorative prints

PLA stands for polylactic acid. It is made from plant-derived materials, including sources such as corn starch and sugarcane. In the video, I highlight it as an approachable material that prints at lower temperatures than ABS.

Its example uses include prototypes, figurines, and other decorative objects.

ABS: strength and durability

ABS stands for acrylonitrile butadiene styrene. The video focuses on its strength and durability, with examples including toys, automotive parts, and household items.

It prints at higher temperatures than PLA. That difference is part of why material selection and printer settings need to work together.

TPU: flexibility and impact resistance

TPU, or thermoplastic polyurethane, is the flexible option in this overview. Its ability to bend and withstand impact makes it useful for objects that need to flex rather than stay completely rigid.

The examples discussed include phone cases, shoe soles, flexible toys, and other flexible parts.

PETG, nylon, and polycarbonate

The video also introduces three additional materials:

  • PETG: presented as a more durable, heat-resistant alternative to PLA, with containers and household items as example applications.
  • Nylon: highlighted for strength and durability, with gears, bearings, and other mechanical parts as examples.
  • Polycarbonate (PC): discussed for heat resistance, with automotive parts and electrical components as example uses.

Match the material to the project

The point of the overview is to look beyond filament color and consider what the finished object needs to do. Does it need to bend? Stay rigid? Handle more heat? Serve as a prototype or a decorative model?

Those questions help narrow the choices. Watch the video below for the full introduction to these filament families and their different uses.
