PETG density and cost per gram

PETG density from Bambu Lab, Polymaker and Prusament datasheets, the price per gram from the makers' stores, and the plastic in a 120 g bracket.

Density, by datasheet

PETG BasicBambu Lab TDS1.25 g/cm³ · 333 m per kg
Prusament PETGPrusament TDS1.27 g/cm³ · 327 m per kg
PolyLite PETGPolymaker1.25 g/cm³ · 333 m per kg

Metres per kilogram of 1.75 mm filament, worked out from each density: a denser plastic puts fewer metres on the same kilogram, so a slicer that reports length needs the density of the roll you load.

Price per gram, by maker

PETG Basic (refill), $13.99 for 1000 gBambu Lab store$0.0140 a gram
Prusament PETG, $32.99 for 1000 gPrusa store$0.0330 a gram

What wall bracket costs in plastic

120 g of model and 6 g of purge and supports, both charged at the spool’s price per gram.

PETG Basic (refill)$1.76
Prusament PETG$4.16

The plastic is one line of a quote. Power, machine hours, your time and failed prints are the rest, and the cost calculator prices them all.

From the PETG datasheets

  • Prusa Polymers gives Prusament PETG a heat deflection temperature of 68 °C at 0.45 MPa.Prusament TDS
  • Polymaker gives PolyLite PETG a heat deflection temperature of 78 °C at 0.45 MPa, and dries it at 65 °C for 6 hours.Polymaker
  • Bambu Lab dries PETG Basic at 65 °C for 8 hours, and its datasheet allows the same in an AMS 2 Pro or AMS HT.Bambu Lab TDS
