⚡️ Quick Tips and Facts

  • 3D printing filaments are the “ink” for your 3D printer—spools of plastic (and sometimes more exotic stuff) that melt and form your creations.
  • The most popular types? PLA, PETG, ABS, TPU, and Nylon—each with its own quirks and superpowers.
  • PLA is the go-to for beginners: easy to print, low odor, and eco-friendly. But if you want strength or flexibility, look at PETG or TPU.
  • Storage matters! Filaments absorb moisture, which can ruin prints. Keep them dry in airtight containers or filament dryers.
  • Not all filaments fit all printers—check your printer’s specs for compatible materials and nozzle temps.
  • Want to see what’s possible? Check out our 3D Printed™ guide to things to 3D print for inspiration!
  • Brands like Bambu Lab, SUNLU, MatterHackers, and Prusament are trusted by enthusiasts worldwide (MatterHackers, Bambu Lab, SUNLU).
  • Pro tip: Always check filament diameter (usually 1.75mm or 2.85mm) and buy from reputable sources to avoid jams and heartbreak.

🧬 What Are 3D Printing Filaments? (Background & Evolution)

a close up of a glass door with a light in it

Let’s rewind to the dawn of desktop 3D printing. Back then, your choices were as limited as a 1990s cell phone plan—mainly ABS and PLA. Fast forward to today, and the filament buffet is overflowing!

3D printing filament is a thermoplastic feedstock for FDM (Fused Deposition Modeling) printers. It’s extruded into thin strands (usually 1.75mm or 2.85mm diameter) and wound onto spools. When heated, it melts and is deposited layer by layer to create objects.

A Brief History

  • Early Days: ABS was king—tough but smelly, requiring heated beds and vented rooms.
  • PLA Revolution: PLA arrived, winning hearts with its ease of use and eco-friendliness (Wikipedia).
  • Material Explosion: Now, you’ll find filaments infused with wood, metal, carbon fiber, and even glow-in-the-dark pigments.

Why So Many Types?

Each filament brings unique properties—strength, flexibility, color, finish, or even electrical conductivity. This explosion of options is driven by hobbyists, engineers, and artists demanding more from their prints (MatterHackers).

“At MatterHackers, we take pride in offering the largest selection of 3D printing filament available.” — MatterHackers

Strength 7 7 6 6 6
Visual Appeal 7 8 10 10 10
Durability 6 6 5 5 5
Eco-Friendly 9 9 9 9 9

What Makes PLA the Darling of 3D Printing?

  • Easy to print: Low warping, no heated bed required.
  • Eco-friendly: Made from renewable resources like corn starch (Wikipedia).
  • Low odor: Your workspace won’t smell like a plastic factory.
  • Vibrant colors and finishes: From matte to silk, marble to rainbow gradients.

PLA Variants Breakdown

  • Classic PLA: The workhorse—great for prototypes, toys, and decorative objects.
  • Matte PLA: Non-glossy finish, perfect for architectural models or stealthy gadgets.
  • Silk PLA: Shiny, smooth, and showy—think cosplay, vases, or display pieces.
  • Gradient/Rainbow PLA: Color shifts along the spool for magical, multi-hued prints.
  • Specialty PLA: Sparkle, metal, marble, wood, and even glow-in-the-dark!

Drawbacks:
❌ Not very heat-resistant (can deform in a hot car).
❌ Brittle compared to PETG or ABS.

User Review:
