Frequently Asked Questions

What is the difference between PLA, PETG, and ABS?

PLA is the easiest to print—low warp, no enclosure needed, but it's brittle and softens around 60°C. PETG is more durable, flexible, and heat-resistant (80°C+) with better chemical resistance; it's slightly trickier to print with more stringing. ABS is the strongest and most heat-resistant (100°C+) but requires an enclosure, heated bed, and ventilation due to fumes and warping. For most users, start with PLA, graduate to PETG for functional parts, and use ABS/ASA only when you need maximum heat resistance or have an enclosure.

How should I store 3D printer filament?

Filament absorbs moisture from the air, which causes poor print quality (bubbling, stringing, weak layers). Store filament in a dry, cool place. Use sealed bags with desiccant for long-term storage. A dry box or cabinet with humidity control (under 20% RH) is ideal for active filaments. Nylon and PETG are most hygroscopic; PLA is more forgiving. If filament has absorbed moisture, dry it in a filament dryer or food dehydrator (40-50°C for 4-6 hours) before printing.

What does diameter tolerance mean for filament?

Diameter tolerance is how much the filament width can vary from the nominal 1.75mm. ±0.05mm is standard for budget filament; ±0.02mm is premium (Prusament). Tighter tolerance means more consistent extrusion—less under/over extrusion, fewer failed prints. For precision parts, dimensional accuracy, or high-speed printing, ±0.02mm or ±0.03mm matters. For casual printing, ±0.05mm is usually fine. Cheap filament with ±0.1mm or unspecified tolerance can cause inconsistent flow.
