Frequently Asked Questions
What is the best filament for beginners?
PLA is the best starter filament—no enclosure, low temps, minimal warping. The Overture PLA and eSUN PLA+ offer the best value for beginners. Overture includes a build surface; eSUN PLA+ adds durability. Avoid ABS and nylon as first filaments. Once comfortable with PLA, try PETG (Polymaker PolyLite) for functional parts. The Polymaker PETG is one of the easier PETG formulations to print.
What is the best filament for functional parts?
PETG is the best all-around choice for functional parts—strong, durable, heat-resistant to 80°C, and chemical resistant. Polymaker PolyLite and Prusament PETG are top choices. For higher heat (100°C+), use ASA (Prusament) or ABS (Hatchbox)—both need an enclosure. For flexible parts (gaskets, grips), use TPU (Polymaker PolyFlex). For maximum strength and temperature, consider nylon or polycarbonate—advanced materials requiring more printer capability.
Is expensive filament worth it?
For precision work, dimensional accuracy, or reducing failed prints, premium filament (Prusament, Fusion Filaments) justifies the cost. The ±0.02mm tolerance and consistency save time and material. For casual printing, budget filaments (Overture, eSUN, Eryone) deliver 85-90% of the quality at 50-70% of the price. The main differentiators are tolerance, color consistency, and reliability. If you're printing functional parts where dimensions matter, invest in premium. For decorative prints, budget is fine.
Can I use different brands of filament interchangeably?
Yes, but you'll need to adjust temperatures. Each brand (and sometimes each color) has slightly different optimal temps. When switching filaments, run a temperature tower to find the sweet spot. eSUN PLA+ might print best at 215°C while Prusament PLA prefers 210°C. PETG varies even more—230-250°C depending on brand. Keep a profile per filament or at least per material type. Diameter can also vary—measure with calipers if you have extrusion issues.
