Resin 3D Printing Cost Calculator

MSLA and SLA slicers report the resin a plate needs in milliliters. Feed that volume and your bottle price per liter into this calculator and it returns the resin cost and the price per milliliter, so you can price a miniature or a full plate in seconds.

How to calculate resin cost

  1. Slice your plate and read the estimated resin volume in milliliters.
  2. Enter that volume into the Resin used field.
  3. Type your resin price per liter into the Resin price field.
  4. Read the total resin cost and the price per milliliter in the result cards.
  5. Copy the cost line to drop into a quote or build log.

Examples

A small miniature

30 ml used, $50 per liter
$1.50 of resin

A larger model

120 ml used, $45 per liter
$5.40 of resin

A mid-size plate on premium resin

50 ml used, $60 per liter
$3.00 of resin

Frequently asked questions

How is resin cost calculated?

Resin is sold by the liter, which is 1000 ml. Cost equals the volume in milliliters divided by 1000, then multiplied by the price per liter. So 30 ml from a 50 dollar liter is 0.03 times 50, which is 1.50 dollars.

Where do I find the milliliters used?

MSLA slicers such as Lychee, ChiTuBox and Photon Workshop show the estimated resin volume in milliliters once you slice a plate. It appears alongside the layer count and print time in the slice summary.

Why is resin priced per liter instead of per kilogram?

Resin is a liquid dispensed by volume from the vat and sold by the bottle in liters, so volume pricing matches how it is measured and poured. Filament, by contrast, is a solid sold by weight, which is why that calculator uses grams.

Do supports and rafts count in the volume?

Yes, and that is what you want. The slicer volume already includes the supports, rafts and any islands on the plate, so the figure reflects the resin actually cured for the whole print.

Does this account for resin wasted in the vat?

No. It prices the plate volume only. Resin lost to cleaning, drips, failed prints and the film left on parts before curing all add real cost, so add a margin if you need a true per-part price.

How do I price a plate with several copies?

Slice the full plate with every copy on it and use the total milliliters it reports. The single figure already covers all the parts plus their shared supports.

What is the largest volume I can enter?

The slider reaches 1000 ml, a full liter bottle. For a run that uses more than a liter, price each liter's worth separately and add the totals.

Does the type of resin change the result?

Only through its price. Standard, ABS-like, water-washable and tough resins are all sold per liter, so enter whatever that specific bottle cost. The milliliters the slicer reports do not depend on the resin chemistry.

Is anything uploaded?

No. The calculation runs in your browser, so the volume and price you enter stay on your device.
