How it works

Estimate filament material cost from weight used, spool weight and spool price.

Estimating method: Cost = print grams ÷ spool grams × spool price.

Worked example

120 g from a 1000 g spool costing £20 is £2.40 of filament.

Common mistakes
  • Ignoring failed prints and purge material.
  • Forgetting electricity and machine time.
  • Using old spool prices.
