Estimate 3D printing costs including filament, electricity, time, and wear. Compare materials and optimize your print settings for the best value.
3D printing has revolutionized prototyping and small-scale manufacturing, but understanding the true cost of each print can be surprisingly complex. Beyond the visible filament or resin expense, you need to account for electricity consumption, printer depreciation, failed print waste, and time invested. Our 3D Printing Cost Calculator helps you break down every component of your printing costs so you can price your prints accurately and optimize your workflow.
Whether you're running a small print farm, selling custom parts on Etsy, or just tracking hobby expenses, this calculator provides a comprehensive cost analysis. Enter your print parameters — filament weight, material type, print duration, and power consumption — and get a detailed breakdown showing material cost, electricity expense, machine wear, and total cost per part. You can also factor in a failure rate to account for the inevitable failed prints that add to your real-world costs.
The calculator supports multiple filament types including PLA, ABS, PETG, TPU, Nylon, and resin, each with different price-per-kilogram defaults. Use the preset buttons to quickly load common print scenarios, from small figurines to large functional parts, and see how different materials and settings affect your bottom line.
Knowing your true 3D printing cost per part helps you price items for sale, compare materials, and optimize settings. This calculator accounts for every cost component so you never underestimate your expenses. This tool is designed for quick, accurate results without manual computation. Whether you are a student working through coursework, a professional verifying a result, or an educator preparing examples, accurate answers are always just a few keystrokes away.
Total Cost = Material Cost + Electricity Cost + Depreciation Cost + Failure Surcharge Material Cost = (filament_grams / 1000) × price_per_kg Electricity Cost = (printer_watts / 1000) × hours × electricity_rate Depreciation = (printer_cost / lifespan_hours) × print_hours Failure Surcharge = Base Cost × (failure_rate / 100)
Result: $3.27
A 45g PLA print taking 3.5 hours on a 200W printer at $0.12/kWh costs about $1.35 in filament, $0.08 electricity, $0.70 depreciation, plus a 10% failure surcharge of $0.21, totaling approximately $3.27.
The true cost of a 3D print extends well beyond the filament you can see on the spool. Material cost is typically the largest component, but electricity, machine depreciation, and failed prints all add up significantly over time. For hobbyists printing occasionally, these hidden costs may seem negligible, but for anyone running a print farm or selling parts, they can make the difference between profit and loss.
Material costs vary dramatically by type. PLA, the most common FDM filament, ranges from $15-30 per kilogram. Engineering materials like Nylon or Polycarbonate can cost $40-80/kg, while specialty filaments with carbon fiber or metal fill can exceed $100/kg. Resin for SLA/DLP printers runs $25-60 per liter for standard resins, with engineering and dental resins costing several times more.
Several strategies can significantly reduce your per-part printing costs. First, optimize your infill percentage — many functional parts work fine at 15-20% infill rather than the default 20-30%. Second, consider your layer height: taller layers print faster, reducing electricity and depreciation costs, though at the expense of surface quality. Third, batch your prints whenever possible to amortize warmup time and bed adhesion materials across multiple parts.
Support material is another hidden cost driver. Redesigning parts to minimize supports can save 10-30% on material costs. Tree supports in modern slicers use less material than traditional supports. For parts that absolutely need supports, consider water-soluble PVA supports if your printer has dual extrusion, as they produce cleaner results with less waste.
PLA remains the most cost-effective material for most applications, offering good strength, easy printing, and the lowest price per kilogram. PETG provides better temperature resistance and flexibility at roughly 1.5x the cost of PLA. ABS is similar in price to PETG but requires an enclosure and has higher electricity costs due to the heated bed requirements. For functional parts needing impact resistance, Nylon or TPU are worth the premium despite costing 2-3x as much as PLA. When comparing materials, consider not just the per-kg price but also the density — denser materials use more weight for the same volume part.
Most slicers like Cura, PrusaSlicer, or OrcaSlicer display the estimated filament weight after slicing. Look for the "Filament used" line in the slice summary.
FDM printers typically draw 100-350W during printing. Check your printer's specifications or measure with a kill-a-watt meter. Resin printers usually draw 50-150W.
Set a failure rate percentage based on your experience. Beginners might set 15-20%, while experienced users might use 5-10%. This adds a proportional surcharge to the base cost.
Generally yes. Standard resin costs $25-50/L compared to $15-30/kg for PLA filament. Resin also requires post-processing supplies like isopropyl alcohol and UV curing.
If you're selling prints or tracking true costs, yes. Divide your printer's purchase price by its expected lifespan in print-hours (typically 5,000-15,000 hours) to get a per-hour depreciation rate.
This covers direct costs well, but for selling you should also add a markup for your time, design work, shipping materials, and profit margin — typically 2-4x the material cost. Use this as a practical reminder before finalizing the result.
