Resin calculator: millilitres, grams and cost

Turns the volume your resin slicer reports into grams and pesos, and adds the cost of isopropyl alcohol and the FEP film, which almost nobody counts.

Updated July 27, 2026

Inputs

What your resin slicer reports, in millilitres.

Supports you did not slice, raft and resin left in the vat.

Enter 0 if you do not want to count it.

If you wash several parts in the same bath, divide the millilitres between them.

Enter 0 if you do not want to count it.

Result

Fill in the fields to see the cost.

Formula

costoPorMl = precioBotella ÷ volumenBotella_mL
mlConsumidos = volumenPieza_mL × (1 + soportesYDesperdicio_% ÷ 100)
costoResina = mlConsumidos × costoPorMl
costoIPA = (mlIPAporPieza ÷ 1000) × precioIPA_porLitro
costoGuantes = paresPorPieza × precioPar
costoTotal = costoResina + costoIPA + costoGuantes
sobranteBotella_mL = volumenBotella_mL − mlConsumidos

Assumptions

  • Bottle volume is the figure on the label (typically 500 mL or 1000 mL) and is assumed full at the start.
  • Part volume is what the resin slicer reports. If you sliced with supports, that volume already includes them and the extra percentage only covers residue.
  • The extra percentage covers supports you did not slice, raft, and resin left in the vat and on the build plate.
  • IPA and gloves are pro-rated per part. If you wash several parts in the same bath, divide the IPA millilitres between them.
  • IPA is counted as consumed; in practice it is reused several times before saturating, so this line item is conservative.

Limitations

  • Excludes electricity, FEP/nFEP film wear, LCD wear and UV curing. Use the total print cost calculator for those.
  • Excludes the cost of disposing of contaminated resin and IPA, which in Mexico must be handled as hazardous waste and never poured down the drain.
  • Resin left in the vat between jobs is not lost if you filter it back into the bottle; this calculation treats it as waste if you declare it in the percentage.
  • Price per millilitre varies widely between standard, ABS-like, water-washable and dental resins; use the price of the bottle you will actually use.

How it is calculated

Formula

masa_g = volumen_mL × densidad_g_mL   ·   costo_resina_mxn = (masa_g / 1000) × precio_mxn_por_kg   ·   costo_total_mxn = costo_resina_mxn + (mL_ipa_por_lavado / 1000) × precio_mxn_por_litro_ipa + (precio_fep_mxn / impresiones_por_fep). Densidad de referencia: 1.05–1.25 g/cm³ para resinas fotopoliméricas de 405 nm, según la ficha del fabricante.

Assumptions

  • Volume comes from the slicer (Chitubox, Lychee or the vendor's own), which already includes supports and raft.
  • Density is the liquid-resin figure published by the manufacturer; cured resin is denser, so the finished part will weigh slightly more.
  • Isopropyl alcohol is counted as a consumable per wash, not as a one-off purchase.
  • FEP film life is entered as a number of prints and comes from your experience, not from a figure of ours.

Limitations

  • It does not estimate the resin that clings to the part and is lost during washing.
  • It does not price responsible disposal of used resin and alcohol, which in Mexico varies by municipality.
  • Factory densities are given as a range (for example 1.05–1.25 g/cm³); picking the wrong end shifts cost by up to 19 %.
  • It does not apply to material-jetting or to industrial resins with densities outside that range.
