Understanding the Formulas Behind the Calculator
This tool uses standard engineering and energy formulas to estimate costs accurately.
1. Filament Cost Formula
Filament Cost=(1000Weight (g))×Cost per kg
Explanation:
- Weight is converted from grams to kilograms
- Then multiplied by filament price per kg
This gives the total material cost.
2. Electricity Consumption Formula
Energy (kWh)=1000Power (W)×Time (hours)
Explanation:
- Power is measured in watts
- Time is in hours
- Division by 1000 converts watt-hours into kilowatt-hours
3. Electricity Cost Formula
Electricity Cost=Energy (kWh)×Cost per kWh
4. Total Cost Formula
Total Cost=Filament Cost+Electricity Cost
Example Calculation
Let’s understand with a real-world example.
Given Data:
- Model Weight = 250 grams
- Filament Cost = $25 per kg
- Print Time = 6 hours
- Electricity Cost = $0.15 per kWh
- Printer Power = 150 watts
Step 1: Filament Cost
250 g = 0.25 kg
Filament Cost = 0.25 × 25 = $6.25
Step 2: Electricity Cost
Energy = (150 × 6) / 1000 = 0.9 kWh
Electricity Cost = 0.9 × 0.15 = $0.135 ≈ $0.14
Step 3: Total Cost
Total = 6.25 + 0.14 = $6.39
Final Result:
- Filament Cost: $6.25
- Electricity Cost: $0.14
- Total Cost: $6.39
- Material Used: 250 g
