With dozens of filament types available, choosing the right material can be overwhelming. This guide breaks down the most popular options and when to use each one.
PLA (Polylactic Acid)
The most popular filament for good reason. PLA is easy to print, biodegradable, comes in thousands of colors, and produces minimal odor. Perfect for decorative prints, prototypes, and learning. Print at 190-220C with no heated bed required.
PETG (Glycol-Modified PET)
The best all-rounder. PETG combines the ease of PLA with better strength, chemical resistance, and heat tolerance. Ideal for functional parts, outdoor use, and food-safe containers. Print at 220-250C.
ABS (Acrylonitrile Butadiene Styrene)
The classic engineering plastic. ABS offers excellent impact resistance and heat tolerance but requires an enclosed printer and produces fumes. Used for automotive parts, power tool housings, and LEGO bricks.
Specialty Filaments
TPU for flexible parts, nylon for strength, carbon fiber composites for stiffness, and wood or metal-fill for unique aesthetics. The filament market continues to innovate rapidly.
