How Much Does Resin 3D Printing Cost?
Usually a few dollars per print in materials, resin, electricity, FEP film wear, and consumables, before labor or a failure buffer. The resin bottle price is the smallest piece of a bigger picture most people don't count.
Resin isn't the whole cost, it's usually the smallest piece
Standard resin runs roughly $25–$35 per liter, with water-washable resins a bit higher ($30–$40/L), ABS-like resins higher still ($35–$50/L), and tough or engineering resins at the top ($50–$80/L, castable resin even more). But the bottle price is only one line item. Electricity, FEP film wear, and consumables (IPA, gloves, filters) all add up on every single print, whether it succeeds or not.
What actually goes into the cost
- Resin, priced and consumed by volume (mL), not weight, at roughly 1.1 g/mL density if you ever need to convert.
- Electricity, resin (SLA/MSLA) printers typically draw 30–100W, less than most FDM printers, so this line item is usually small.
- FEP film wear, the film at the bottom of the vat clouds and pits with use, commonly lasting 20–60 prints before it needs replacing. Divide the film's cost by how many prints it lasts to get a per-print figure.
- Consumables, isopropyl alcohol for washing, gloves, and filters, a small but real cost on every print.
- A failure buffer, resin failures are usually a supports or bed-adhesion problem rather than the extrusion issues FDM prints see, but the cost logic is the same: spread the occasional ruined print across the successful ones.
A worked example
A 65 mL miniature at $30/L resin costs $1.95 in resin alone. Add a 3-hour print at 50W ($0.03 in electricity), a $18 FEP film good for 40 prints (45 cents this print), and a dollar in consumables, and the subtotal is $3.43. A 10% failure buffer adds 34 cents, for a true cost of about $3.77 before any markup.
Notice how small the resin itself is in that total, about half. The other half is electricity, film wear, and consumables that a bottle-price-only estimate misses entirely.
How this differs from FDM filament
The framework is the same, real material cost plus the recurring costs a filament-only calculator won't capture, but the specific line items differ. FDM has machine wear and a spool that just sits there; resin has FEP film that wears out on a schedule and wash-and-cure consumables that FDM doesn't need at all. If you print both, expect to run two different calculators, not one with a resin checkbox bolted on.
