How many meters of 1.75mm ASA filament are in a 1 kg spool?
388.6 meters(approx. 1,275 feet)
A 1 kg spool of 1.75 mm outdoor-grade ASA filament contains roughly 388.6 meters (1,275 feet) of filament.
Worked Mathematical Derivation
Key Formulation:
Volume V = 1000g / 1.07 g/cm³ = 934.58 cm³. Cross section = 0.02405 cm². Length L = 934.58 / 0.02405 = 38,855 cm = 388.55 meters.Calculate Custom Weight or Length

Quick Rule of Thumb
Standard 1.75mm PLA yields approximately 330–335 meters per 1 kg spool. PETG yields ~327m, and ABS yields ~400m due to lower density.⚡

Frequently Asked Questions
How many meters of 1.75mm ASA filament are in a 1 kg spool?
A standard 1 kg spool of ASA contains 388.6 meters (1,275 feet). Volume V = 1000g / 1.07 g/cm³ = 934.58 cm³. Cross section = 0.02405 cm². Length L = 934.58 / 0.02405 = 38,855 cm = 388.55 meters.
How many hours of printing can you get from 1kg of ASA?
A 1kg spool typically yields between 40 and 80 hours of active printing time, depending on layer height, printing speed, and infill density (e.g. standard 50g models taking 3-4 hours each).
How much does an empty 1kg filament spool weigh?
An empty 1kg filament spool typically weighs between 190g and 260g. Cardboard spools (eSun, Polymaker) weigh ~200g-220g, while sturdy plastic spools (Bambu Lab, Prusament) weigh ~240g-250g.
Why does a 1kg spool of ASA have a different length than other plastics?
Filament length is inversely proportional to polymer density (L = Volume / Area, where Volume = Mass / Density). Lighter polymers like ABS (1.04 g/cm³) yield ~400 meters per kg, while denser materials like PLA (1.24 g/cm³) yield ~335 meters, and PETG (1.27 g/cm³) yields ~327 meters.
How many standard 3DBenchy boats can you print from 1kg of ASA?
A standard sliced 3DBenchy with 2 perimeters and 10% infill weighs approximately 11 to 13 grams. A full 1kg spool can print approximately 75 to 90 complete Benchy models without running out.
