ABS filament density typically ranges from 1.00 to 1.06 g/cm3, equivalent to 1000 to 1060 kg/m3, with most common spools (Hatchbox, Polymaker, Bambu) landing at 1.04 to 1.05 g/cm3. Enter a density value to convert between g/cm3 and kg/m3. This matters when entering ABS material properties into slicers, when estimating the weight and cost of a print, or when working out how many meters remain on a spool. Glass-filled ABS sits a touch higher near 1.06 g/cm3.

How to Convert g/cm³ to kg/m³
Multiply g/cm3 by 1000 to get kg/m3. This is a simple unit scaling: 1 g/cm3 = 1000 kg/m3 exactly. For ABS: standard density is 1.04 g/cm3 (1040 kg/m3). ABS is lighter than PLA and PETG, which is why a 1 kg ABS spool contains more meters of filament than a 1 kg PLA spool of the same diameter.
Example: 1.04 g/cm³ × 1000 = 1040 kg/m³ (ABS)
Common ABS densities by brand
ABS densities sit in a narrow band, so the numbers below are far more useful than a generic 1 to 1000 scale. The last column shows roughly how many meters of 1.75 mm filament fit on a standard 1 kg spool at that density: lower density yields more length per kilogram.

Worked example: weighing an ABS print
If your slicer reports 30 cm³ of plastic for an ABS model, multiply that volume by the ABS density to get the mass: 30 cm³ × 1.04 g/cm³ = 31.2 g. Glass-filled ABS at 1.06 g/cm³ would weigh slightly more for the same volume (30 × 1.06 = 31.8 g), so always match the density to your exact spool when estimating cost.
Frequently Asked Questions
What density value should I enter in my slicer for ABS?
Most slicers accept density in g/cm3. Standard ABS is 1.04 g/cm3, though it ranges from 1.00 to 1.06 g/cm3 depending on formulation and color additives. Black ABS is often near 1.04, while translucent versions may be slightly lower. For the most accurate filament weight estimates, use the density from your filament manufacturer's technical datasheet.
How does ABS density affect filament length on a 1 kg spool?
Because ABS density (1.04 g/cm3) is lower than PLA (1.24 g/cm3), a 1 kg ABS spool at 1.75 mm diameter contains approximately 400 meters, compared to about 335 meters for PLA. If you switch from PLA to ABS and your slicer shows more filament length remaining, this is the reason: lower density means more length per gram.
Why does ABS have a lower density than PETG or PLA?
ABS has a density of 1.00 to 1.06 g/cm³ compared to PETG (1.23 to 1.27 g/cm³) and PLA (1.20 to 1.27 g/cm³). ABS is an amorphous polymer with a bulkier molecular structure, which prevents molecules from packing as tightly. This is also why ABS prints lighter per meter and why a 1 kg ABS spool contains noticeably more filament by length than a 1 kg PLA spool.
