About this calculator
SLA and MSLA printing consume resin equal to the combined volume of the model and its supports. The material cost is that total volume in milliliters, divided by 1,000 to convert to liters, times the resin price per liter: Cost = (modelVolume + supportVolume) × resinPrice / 1000. Slicers such as Chitubox and Lychee report both volumes. Add a few percent for resin left on the build plate, in the vat film and in supports you trim off. Print time is a separate quantity that depends on the model's height, layer height and exposure; use the Resin 3D Printing Calculator for a time estimate.
How to use
Suppose your model is 35 ml, supports add 8 ml, and resin costs $45/L. Cost = (35 + 8) × 45 / 1000 = 43 × 0.045 = $1.94. With the default 15 ml model and 5 ml of supports at $45/L the cost is $0.90.
Frequently asked questions
How do I find the resin volume of my 3D model before printing?
Most slicing software — such as Chitubox, Lychee Slicer, or PrusaSlicer — reports model volume and estimated resin consumption directly in the print preview screen. You can also use CAD tools like Fusion 360 or Blender to check mesh volume before importing into your slicer. Support volume is usually listed separately once you generate supports in the slicer. If your slicer only shows weight, divide by the resin density (typically ~1.1 g/ml) to get volume in milliliters.
What is a typical resin price per liter for SLA 3D printing?
Standard hobbyist resins generally range from $20 to $50 per liter, with budget brands like Elegoo or Anycubic sitting at the lower end. Engineering-grade or specialty resins (ABS-like, flexible, castable) can cost $60–$150 per liter or more. Water-washable resins sit in the mid-range around $35–$60/L but save on IPA solvent costs. Buying in bulk (500 ml vs. 1 L bottles) rarely saves money per milliliter, so compare unit prices carefully.
How does layer height affect SLA print time and resin cost?
A smaller layer height increases the total number of layers for a given model height, which directly increases print time because each layer still requires a full UV exposure cycle. However, layer height does not change the total volume of resin consumed — that depends only on model and support geometry. Thinner layers (e.g., 0.025 mm) can roughly double print time compared to 0.05 mm layers while producing finer surface detail. For cost-sensitive prints, using a larger layer height (0.1 mm) cuts time significantly with minimal impact on resin usage.
