1. What is Filament Cost per Gram?

Definition: This calculator determines the cost per gram of 3D printing filament based on the total price and weight of the filament spool.

Purpose: It helps 3D printing enthusiasts and professionals compare filament costs accurately and budget for their printing projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_g \) — Cost per gram ($/g)
• \( P \) — Price of filament spool ($)
• \( W \) — Weight of filament (grams)

Explanation: The total price of the filament spool is divided by its weight to determine the cost per gram.

3. Importance of Calculating Filament Cost

Details: Knowing the cost per gram helps in budgeting printing projects, comparing different filament options, and estimating material costs for specific prints.

4. Using the Calculator

Tips: Enter the total price of the filament spool in dollars and the filament weight in grams. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate cost per gram instead of using spool price?
A: Filament spools come in different weights (250g, 500g, 1kg, etc.), so cost per gram allows direct comparison between different products.

Q2: Should I include shipping costs in the price?
A: For accurate cost analysis, include any additional costs like shipping or taxes in the total price.

Q3: Does this account for empty spool weight?
A: No, use the net filament weight (total weight minus spool weight) for most accurate results.

Q4: How can I reduce my filament costs?
A: Buy larger spools (usually cheaper per gram), wait for sales, or consider bulk purchases with other makers.

Q5: What's a typical cost per gram for PLA filament?
A: Standard PLA typically ranges from $0.03 to $0.06 per gram, while premium or specialty filaments may cost more.
