Resin Print Cost Calculator

Calculate the cost of SLA/MSLA resin printing including supports, resin usage, wash and cure consumables, and FDM cost comparison.

About this calculator

Resin printing consumes more material per print than the finished model's own volume suggests, because most resin prints need support structures to hold overhanging features in place during printing, and those supports are made of the same expensive resin as the model itself. This calculator adds your estimated support percentage on top of model volume to get total resin consumed, then converts that through your resin's price per liter (divided down to a per-milliliter rate) to get the pure resin cost. Total cost per print adds a flat wash-and-cure consumables charge on top — the isopropyl alcohol for cleaning, gloves, paper towels, and the electricity for UV curing that every resin print requires regardless of the model's size, which is why this per-print overhead matters proportionally more for small, cheap prints than for large ones.

Prints per liter is simply how many times your total resin volume (model plus supports) divides into a standard one-liter bottle, rounded down since a partial print's worth of resin left in the bottle isn't enough for another complete print. The FDM comparison converts your resin volume into an equivalent weight using resin's density (about 1.1 g/mL) and prices that weight against a generic PLA filament cost, giving a rough sense of how resin's higher material cost compares to standard FDM printing for the same-sized part — useful context for deciding whether a given print actually needs resin's finer detail and smoother surface finish, or whether FDM would serve the purpose for meaningfully less material cost.

How to Use This Calculator
  1. Enter model volume (cm³) from your resin slicer software and resin price per liter.
  2. Set support material percentage (typically 10–20% of model volume for complex parts).
  3. Enter wash and cure consumable costs (IPA, FEP film amortization, etc.).
  4. Review total cost per print, resin-only cost, total resin volume used, and prints per liter.

What each input means

Model Volume
Volume of the model in milliliters (from slicer software).
Resin Price per Liter
Cost of one liter of resin. Standard resins are $25-40/L, specialty resins $50-100+/L.
Support Material
Estimated percentage of extra resin used for support structures. Typically 10-30%.
Wash & Cure Consumables
Per-print cost of IPA/cleaning solution, gloves, paper towels, and electricity for UV curing.

Frequently Asked Questions

Why does support material meaningfully increase the cost, not just the print time?

Support structures in resin printing are printed from the same resin as the model itself, and that resin is fully consumed by the print regardless of whether it ends up as part of the finished model or gets removed and discarded as waste after printing. A model needing 20% support material effectively uses 20% more resin than its own volume alone would suggest, which translates directly into real added cost, not just added printing time.

Why does the wash and cure cost matter more for small prints than large ones?

Wash and cure consumables — IPA, gloves, and the electricity to run a UV curing station — are charged as a flat per-print cost regardless of how large or small the model is, since a batch of tiny miniatures uses roughly the same wash-and-cure resources as one larger model. For a small, low-volume print, that flat overhead can represent a meaningful share of the total cost, while for a large print it becomes a comparatively minor add-on to the much larger resin cost.

Is the FDM cost comparison telling me FDM is always cheaper?

It's showing a rough material-cost comparison for an equivalent amount of plastic, and resin does typically cost more per gram than standard PLA filament, so the comparison usually favors FDM on pure material cost. But that comparison doesn't account for what each process is actually good at — resin excels at fine detail and smooth surface finish that FDM struggles to match, so the right choice depends on what the print actually needs, not material cost alone.

Why does prints-per-liter round down instead of showing a fractional number?

A bottle of resin genuinely runs out partway through a print if there isn't enough left for a complete pour, so a fractional result like 6.7 prints per liter would overstate how many full prints you can actually complete from one bottle. Rounding down to 6 gives a realistic, actionable number for planning how many bottles to order for a given number of prints.
