とは何か 3D Printing Cost Calculator?
▾
A 3D print cost calculator estimates what a printed part actually costs once you add up material, electricity, machine time, and the waste that comes from supports or failed prints. That matters because the sticker price of a filament spool tells only a small part of the story. A hobbyist printing a phone stand might spend well under two dollars, while a business producing prototypes every day needs to understand per-part cost, machine utilization, and reprint rates to price jobs properly. Designers, makers, Etsy sellers, classrooms, engineering teams, and print farms all use cost estimates to decide whether a part should be printed in-house, outsourced, resized, or redesigned. In simple terms, the calculator measures how much plastic or resin you consume, how long the printer runs, what power it draws, and whether you want to include overhead such as labor, maintenance, or machine depreciation. For FDM printing, material use usually dominates on small jobs, but electricity and failed prints can matter more on long prints, heated chambers, or high-temperature materials. For resin printing, post-processing, wash-and-cure supplies, and supports often change the economics. Good cost estimates also help with quoting. If you underprice parts, you may lose money even when the print looks successful. If you overprice them, you may lose customers. A calculator gives a repeatable baseline so you can compare PLA versus PETG, low infill versus solid parts, or one-off prototypes versus small production runs with more confidence.

公式

Total print cost = Material cost + Electricity cost + Optional overhead. Material cost = material used x price per unit. Electricity cost = print time (hours) x printer power (kW) x electricity rate. Worked example: 50 g of PLA at $25/kg costs 50 x 25 / 1000 = $1.25. If the printer uses 0.12 kW for 3 hours at $0.18/kWh, electricity cost = 3 x 0.12 x 0.18 = $0.0648, or about $0.06. Total estimated cost = $1.25 + $0.06 = about $1.31 before overhead.変数の説明

方法 3D Printing Cost Calculator
▾
- 1Enter the material consumed by the print, usually in grams for filament or milliliters for resin, along with the material price per kilogram or liter.
- 2Add print time, printer power draw, and your local electricity rate so the calculator can estimate energy cost.
- 3If you want a business-grade estimate, include extra overhead such as labor, nozzle wear, failed print allowance, or machine depreciation.
- 4The calculator computes material cost first, then electricity cost, and finally adds any optional overhead to produce a total cost per part.
- 5Compare several scenarios by changing material type, infill, layer height, or print orientation to see which design choice is most economical.
- 6Use the result for quoting or budgeting, then review your slicer estimate and real-world print history because actual usage can differ from theory.

This is a typical hobby print where material cost is the main driver. Adding a small failure allowance or labor charge would increase the quoted price.
Longer prints make electricity and failure risk more meaningful. If the part has tall supports, the effective material cost can rise quickly.
For resin printing, washing and curing supplies can matter almost as much as the power bill. A cost calculator keeps those hidden consumables visible.
This scenario shows why businesses usually quote more than raw filament plus power. Failed prints, tuning time, and machine wear are real costs.
実際の応用
▾
Quoting custom prints for customers or internal engineering teams
Comparing materials, infill settings, and print orientations before production
Tracking profitability for a hobby shop, classroom lab, or print farm
特殊なケース
▾
Large batch printing should spread setup time and failed-print allowance across
Large batch printing should spread setup time and failed-print allowance across all successful parts instead of charging every item as if it were a one-off job.
If the print is safety-critical or customer-facing, quality-control labor,
If the print is safety-critical or customer-facing, quality-control labor, sanding, painting, packaging, and warranty risk should be added because the raw machine estimate will be too low.
When input values approach zero or become negative, the 3D Print Cost
When input values approach zero or become negative, the 3D Print Cost calculation may produce undefined or misleading results. Always validate that inputs fall within the model's valid range before interpreting outputs. Extreme values should be flagged for manual review.
Example Cost Drivers for Common Print Jobs
▾
| Scenario | Material Use | Print Time | Typical Cost Pattern |
|---|---|---|---|
| Small PLA accessory | 30-60 g | 1-3 h | Material dominates; very low power cost |
| PETG functional part | 100-250 g | 4-10 h | Material still leads, but failures matter more |
| ABS enclosed print | 150-300 g | 6-14 h | Higher power and overhead due to heat and warping risk |
| Resin miniatures | 50-150 mL | 2-6 h | Post-processing supplies are a meaningful cost |

How does the 3D Printing Cost Calculator work?
Enter the material consumed by the print, usually in grams for filament or milliliters for resin, along with the material price per kilogram or liter. Then: Add print time, printer power draw, and your local electricity rate so the calculator can estimate energy cost. Then: If you want a business-grade estimate, include extra overhead such as labor, nozzle wear, failed print allowance, or machine depreciation. Then: The calculator computes material cost first, then electricity cost, and finally adds any optional overhead to produce a total cost per part..
Can you give an example of how to use the 3D Printing Cost Calculator?

避けるべきよくある間違い
▾
- !Using incorrect or mismatched units for input values
- !Forgetting to account for edge cases or boundary conditions
- !Rounding intermediate values too early in the calculation
- !Not verifying that input values fall within valid ranges for 3d print cost
プロのヒント
Use the slicer's estimated part weight and support weight separately, because support-heavy prints often cost more than people expect. For best results with the 3D Print Cost, always cross-verify your inputs against source data before calculating. Running the calculation with slightly varied inputs (sensitivity analysis) helps you understand which parameters have the greatest influence on the output and where measurement precision matters most.
ご存知でしたか？
Changing infill from 100% solid to a well-chosen 15% to 25% pattern can cut material use dramatically while preserving most of the part's functional strength for many designs.
