Filament Guide

Filament Guide

Filament is the material your piece is 3D-printed from — the plastic "thread" the printer melts and shapes layer by layer. Pick the right one for the job below: strength, flex, heat and sun tolerance, and how print speed affects price, at a glance.

The PLA Family

All print the same way — they just look different.

PLA

Best for Indoor display pieces & colorful gifts

Wide Range of colors & shades $
Strength: Med
Flex: Low
Durability: Med
Heat: Low
Sun: Avoid
Speed: Fast

Easiest filament to print — solid shades, gradients, and rainbow blends alike. Just keep it out of the sun and hot cars.

PLA Matte

Best for Sculptural pieces & fingerprint-free gifts

Wide Range of colors & shades $
Strength: Med
Flex: Low
Durability: Med
Heat: Low
Sun: Avoid
Speed: Fast

Same easy PLA printing, with a soft, low-glare finish that hides fingerprints and layer lines.

PLA Silk

Best for Eye-catching indoor showpieces

Wide Range of colors & shades $$
Strength: Med
Flex: Low
Durability: Low
Heat: Low
Sun: Avoid
Speed: Med

A glossy, silky sheen instead of a matte finish — same PLA care, slightly more delicate to the touch.

Glow In The Dark

Best for Night-lights & fun novelty pieces

Green, Red, Blue & Rainbow $$
Strength: Low
Flex: Low
Durability: Med
Heat: Low
Sun: Avoid
Speed: Med

Charges under light and glows in the dark for a while — otherwise handles just like regular PLA.

Color Changing

Best for Playful indoor pieces that react to light

Limited Range of colors, 2 shades $
Strength: Med
Flex: Low
Durability: Med
Heat: Low
Sun: Avoid
Speed: Fast

Shifts color with heat or sunlight by design — a fun effect, but the base plastic still prefers indoor life.

Wood PLA

Best for Rustic, natural-look decor

Limited Range of shades $$
Strength: Low
Flex: Low
Durability: Med
Heat: Low
Sun: Avoid
Speed: Med

Real wood fiber blended in — sandable and natural-looking, but more brittle than standard PLA.

When You Need More Than Looks

Tougher, more heat- and sun-resistant materials for functional or outdoor pieces.

PETG

Best for Everyday-use items and functional parts

Middle Range of colors $$
Strength: High
Flex: Med
Durability: High
Heat: Med
Sun: OK
Speed: Med

Tougher and more heat-safe than PLA — a great step up when a piece needs to survive daily use.

ASA

Best for Outdoor signs & car accessories

Limited Range of colors $$$
Strength: High
Flex: Med
Durability: High
Heat: High
Sun: High
Speed: Slow

Built for the outdoors — UV-stable and heat-resistant, with a slower print that adds to the price.

Flexible TPU

Best for Wearables, phone cases & snap-fit parts

Limited Range of colors $$$
Strength: Med
Flex: High
Durability: High
Heat: Med
Sun: OK
Speed: Slow

Bends and flexes instead of breaking — the slow, careful print adds to the price, but it's worth it for wearable or snap-fit parts.
