1. What is the Average Cost of 20 Grams of Filament?

Definition: This calculator estimates the cost of 20 grams of 3D printing filament based on the price per gram.

Purpose: It helps 3D printing enthusiasts and professionals estimate material costs for small prints or portions of larger projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Cost for 20 grams of filament ($)
• \( P_f \) — Price per gram of filament ($/g)

Explanation: The price per gram is multiplied by 20 to calculate the cost for 20 grams of material.

3. Importance of Filament Cost Calculation

Details: Accurate cost estimation helps with project budgeting, comparing material options, and determining print profitability.

4. Using the Calculator

Tips: Enter the price per gram of your filament (typically $0.02-$0.04/g for PLA). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate for 20 grams specifically?
A: 20 grams is a common amount for small to medium 3D prints, making it a useful reference point.

Q2: What's a typical price per gram for filament?
A: PLA filament typically costs $0.02-$0.04 per gram, while specialty materials may cost more.

Q3: Does this include electricity or other costs?
A: No, this calculates only the material cost. Additional costs like electricity, machine wear, etc. should be considered separately.

Q4: How can I find my filament's price per gram?
A: Divide the spool price by its weight in grams (e.g., $20 for 1kg = $0.02/g).

Q5: Does this account for material waste during printing?
A: No, consider adding 5-15% to the calculated cost for typical printing waste and supports.
