PLAIs cost effective and best for simple models and display items.

PETG Is similar in cost to PLA, but stronger and more durable with some flexibility.

ABS Is tough and heat-resistant for functional parts.

TPU Is a flexible, rubber-like plastic used for parts that need to bend or absorb impact.

GF Glass fiber filament offers better impact resistance, flexibility, and electrical insulation, but at a higher cost.

CF Carbon fiber filament provides superior stiffness, strength-to-weight ratio, and rigidity, but at a higher cost.
