How 3D Print Costing Works
3D print costing is the process of calculating the total expense of producing a single 3D-printed part by combining material, electricity, and equipment depreciation costs. According to Grand View Research, the global 3D printing market reached $20.4 billion in 2024 and is projected to grow at 23.5% annually through 2030. As desktop 3D printing becomes mainstream, with over 2 million consumer FDM printers sold in 2024 alone according to Statista, accurate cost estimation is essential for hobbyists tracking expenses, sellers pricing products on Etsy and Amazon, and businesses comparing 3D printing to traditional manufacturing.
This calculator computes three cost components: material (filament or resin consumed), electricity (power drawn during the print), and depreciation (wear on the printer over its useful life). Many hobbyists only consider material cost, but electricity and depreciation typically add 20-40% to the true cost per print. For makers selling prints commercially, understanding full costs is the foundation for profitable pricing. Pair this with our Pricing Calculator to determine your selling price after applying a profit margin.
The 3D Print Cost Formula
Total print cost is the sum of three components: Material Cost = Weight (g) x Price per kg / 1000. Electricity Cost = Printer Watts / 1000 x Print Hours x Electricity Rate per kWh. Depreciation Cost = Printer Purchase Price / Estimated Lifespan Hours x Print Hours. The total is Material + Electricity + Depreciation.
Worked example: A 50g PLA print on a 200W printer running for 4 hours. PLA costs $25/kg, electricity is $0.12/kWh, printer cost $300 with 2,000 estimated print hours. Material = 50 x 25 / 1000 = $1.25. Electricity = 200/1000 x 4 x 0.12 = $0.096. Depreciation = 300/2000 x 4 = $0.60. Total = $1.95. To sell this print profitably, apply a 2-3x markup for a selling price of $3.90-$5.85, plus additional markup for labor and failed prints. Calculate your monthly electricity costs if you run a print farm.
Key Terms You Should Know
- FDM (Fused Deposition Modeling) — The most common desktop 3D printing technology. Melts thermoplastic filament and deposits it layer by layer. Typical filaments include PLA, PETG, ABS, and TPU.
- SLA/MSLA (Stereolithography) — Resin-based 3D printing that uses UV light to cure liquid photopolymer resin. Produces smoother, more detailed parts than FDM but requires post-processing (washing and curing).
- Filament — Thermoplastic material sold in 1kg spools for FDM printers. PLA costs $15-25/kg, PETG $20-30/kg, and specialty filaments $30-80/kg.
- Infill Percentage — The density of internal structure inside a print. 20% infill is standard for decorative items, 40-60% for functional parts, and 100% for maximum strength. Higher infill uses more material and time.
- Depreciation — The cost of printer wear allocated per hour of use. A $300 printer lasting 2,000 hours depreciates at $0.15/hour. This accounts for eventual replacement of the hotend, bed, belts, and other wear components.
- Post-Processing — Work done after printing: support removal, sanding, painting, acetone smoothing, or UV curing for resin prints. Adds labor time not captured by material-only cost estimates.
3D Printing Material Cost Comparison
Material cost varies widely by filament type. The following table shows typical prices, properties, and cost per 50g print for common 3D printing materials as of 2026.
| Material | Price/kg | Cost per 50g | Strength | Best For |
|---|---|---|---|---|
| PLA | $15-25 | $0.75-1.25 | Moderate | Prototypes, decorative items |
| PETG | $20-30 | $1.00-1.50 | Good | Functional parts, outdoor use |
| ABS | $18-28 | $0.90-1.40 | Good | Heat-resistant parts, enclosures |
| TPU | $25-40 | $1.25-2.00 | Flexible | Phone cases, gaskets, grips |
| Nylon | $30-50 | $1.50-2.50 | Excellent | Gears, hinges, snap fits |
| Standard Resin | $25-40/L | $1.25-2.00 | Brittle | Miniatures, jewelry, dental |
| Tough Resin | $40-70/L | $2.00-3.50 | Good | Functional resin parts |
Practical Examples
Example 1 — Phone Stand (FDM): 30g PLA at $20/kg, 2-hour print on a 180W printer at $0.12/kWh, printer cost $250 with 2,000-hour lifespan. Material = $0.60. Electricity = $0.04. Depreciation = $0.25. Total = $0.89. To sell on Etsy at a 3x markup: $2.67, rounded to $2.99 retail.
Example 2 — Custom Miniature (Resin): 15mL resin at $35/L, 3-hour print on a 70W MSLA printer at $0.12/kWh, printer cost $400 with 1,500-hour lifespan. Material = $0.53. Electricity = $0.03. Depreciation = $0.80. Total = $1.36. With 30 minutes of post-processing labor at $15/hr ($7.50) and a failed print rate of 10% (add 10%): selling price should be at least $9.75-$13 to be profitable.
Example 3 — Large Functional Part (PETG): 200g PETG at $25/kg, 14-hour print on a 250W printer at $0.14/kWh, printer cost $600 with 3,000-hour lifespan. Material = $5.00. Electricity = $0.49. Depreciation = $2.80. Total = $8.29. This is the production cost only. Use our Filament Calculator to estimate material usage from slicer settings before printing.
Tips and Strategies
- Account for failed prints. Industry data suggests a 5-15% failure rate for experienced users and 15-30% for beginners. Add 10-15% to your cost estimates as a failure buffer when pricing prints for sale.
- Buy filament in bulk. Purchasing 5-10 kg at a time reduces per-kg costs by 15-25%. Store unused filament in vacuum-sealed bags with desiccant to prevent moisture absorption, which causes print quality issues.
- Optimize infill for cost savings. Reducing infill from 20% to 15% saves roughly 8-10% on material with minimal strength loss for decorative items. Use our Resin Calculator for SLA material estimation.
- Track electricity accurately. A smart plug with power monitoring (like the Kasa Smart Plug) costs $10-15 and shows real-time power draw, giving you precise electricity cost data instead of estimates.
- Include post-processing time in pricing. Support removal, sanding, painting, and assembly can take 30 minutes to several hours. At $15-20/hour labor rate, this often exceeds the material cost.
- Use a 2.5-3x markup for retail sales. This covers material, electricity, depreciation, labor, failed prints, marketplace fees (typically 10-15%), packaging, and shipping while providing reasonable profit.
Frequently Asked Questions
What is the biggest cost in 3D printing?
For FDM (filament) printing, material is usually the largest cost component, accounting for 50-70% of the total production cost. For resin (SLA/MSLA) printing, resin cost similarly dominates, especially with specialty resins costing $40-70 per liter. Electricity is typically a minor factor at 2-5% of total cost. Printer depreciation matters most for low-volume users who spread the purchase price over fewer prints, sometimes representing 20-30% of cost per part.
How do I price 3D prints for sale?
The standard formula is: (Material + Electricity + Depreciation + Labor) multiplied by a 2-3x markup factor. Calculate production cost using this calculator, then add labor time for post-processing (support removal, sanding, painting) at $15-20 per hour. Add 10-15% for failed print waste. Apply a 2x markup for wholesale or 3x for retail. Factor in marketplace fees (Etsy 6.5%, Amazon 15%) and packaging costs. A $2 production cost print typically sells for $6-10 retail.
How much electricity does a 3D printer use?
A typical FDM printer draws 100-250 watts depending on the heated bed temperature and hotend. A 10-hour print at 200W and $0.12/kWh costs about $0.24 in electricity. Over a month of heavy use (300 hours), total electricity cost is approximately $7.20. Resin printers typically use less power at 50-100W for the LCD screen and UV LEDs, but UV curing stations add 20-50W for 10-30 minutes per print. Use a smart plug with power monitoring for precise tracking.
How do I estimate material usage before printing?
Your slicer software (Cura, PrusaSlicer, Bambu Studio) calculates exact material weight after you load the 3D model and set your print settings. The estimate accounts for infill density, wall thickness, support structures, and brim or raft. As a rough rule, infill has the biggest impact: a 100x100x100mm cube uses approximately 15g at 10% infill, 30g at 20%, and 120g at 100%. Use our Filament Calculator for pre-slicer estimates.
Is 3D printing cheaper than buying products?
For one-off custom parts, replacement components, and prototypes, 3D printing is almost always cheaper than buying custom-machined alternatives. A $2 printed bracket replaces a $15-50 custom metal part. However, for mass-produced items available on Amazon, buying is usually cheaper than printing because injection molding at scale costs pennies per part. 3D printing excels at customization, low-volume production (under 100 units), and items that do not exist commercially.
How long do 3D printers last before needing replacement?
A well-maintained desktop FDM printer typically lasts 2,000-5,000 print hours before major components need replacement. Individual parts wear at different rates: nozzles last 200-500 hours (brass) or 1,000+ hours (hardened steel), PTFE tubes last 500-1,000 hours, and belts and bearings last 2,000-3,000 hours. The frame and electronics usually outlast all other components. Budget $50-100 per year for replacement parts on a printer used 500+ hours annually.
