3D Resin Volume Calculator

Enter your print volume to estimate resin usage and cost.

How it is calculated

The tool takes the solid volume of the model in cm³ (the figure your slicer reports), and since 1 cm³ equals 1 mL it uses resin_mL = volume. Mass is mass_g = mL × density, with density in g/mL; if you leave density empty it uses 1.1. If you give a price per litre, cost = mL / 1000 × price is also shown, in dollars; with no price the cost line is omitted. Results are rounded to two decimals. The tool does not add anything for supports, a raft, failed prints or resin left on the vat and tools, so add that margin yourself or enter the slicer volume that includes supports.

Worked example

A miniature has a solid volume of 45 cm³, resin density of 1.1 g/mL, and the resin costs 40 per litre. Volume: 45 cm³ = 45.00 mL. Mass: 45 × 1.1 = 49.50 g. Cost: 45 / 1000 × 40 = $1.80. If supports add another 8 mL, entering 53 would give a more realistic cost of about $2.12 for the whole print.

Common mistakes

  • Entering the bounding box volume of the model instead of its solid volume; the box can be several times larger than the resin actually used.
  • Entering the price of a bottle (for example 500 mL) in the price field, which expects the price per litre; divide or multiply to get the per-litre price first.
  • Forgetting supports, raft and cleaning losses, so the real consumption is higher than the model volume.
  • Entering the volume in mm³ instead of cm³, which makes the result 1,000 times too large.
  • Leaving density empty for an unusual resin; the default of 1.1 g/mL may differ from the datasheet value.

About this calculator

For resin (SLA/DLP/LCD) 3D printing, the resin needed roughly tracks the model's solid volume, where 1 cm³ equals 1 mL; converting that volume to mass uses the resin's density (typically 1.1–1.2 g/mL, with 1.1 used if you leave it blank), and cost is the volume in litres times the resin's price per litre (cost = mL ÷ 1000 × price per litre). Supports and waste are not added, so include them in the volume you enter if you want to budget for them.

Hobbyist 3D printing enthusiasts use this to estimate how much of an expensive resin bottle a print will consume before starting it, and miniature and prop sellers — on marketplaces like Etsy — use the same numbers to price their prints by factoring material cost into what they charge.

    Resin is usually sold by weight, not by volume. To get the per-litre price this tool asks for, multiply the bottle's price per kilogram by the resin's density: at 1.1 g/mL, a 30 per kg resin costs about 33 per litre. Check the density on the datasheet rather than guessing. Which resin and slicer are you using, and does its volume figure include supports?
