1. What is Filament Price per Gram Calculator?

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 across different spool sizes and brands.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_g \) — Cost per gram ($/g)
• \( P_f \) — Total price of filament spool ($)
• \( W_f \) — Total weight of filament (grams)

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

3. Importance of Price per Gram Calculation

Details: Calculating price per gram allows for accurate cost comparisons between different filament spools, regardless of their size or packaging.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why calculate price per gram instead of just comparing spool prices?
A: Spools come in different weights (500g, 1kg, etc.), so price per gram allows direct comparison regardless of package size.

Q2: Should I include shipping costs in the price?
A: For accurate total cost, yes. Include all costs associated with acquiring the filament.

Q3: What's a typical price range for filament?
A: Common PLA filament typically ranges from $0.03 to $0.10 per gram, with specialty filaments costing more.

Q4: Does this account for the empty spool weight?
A: No, use the net filament weight (usually listed on the packaging as "filament weight").

Q5: How can I use this for cost estimation?
A: Multiply the price per gram by your model's weight (from slicer software) to estimate material cost.
