1. What is Price of PLA Filament per Gram?

Definition: This calculator determines the cost per gram of PLA (Polylactic Acid) filament, commonly used in 3D printing.

Purpose: It helps 3D printing enthusiasts and professionals calculate material costs for their projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Price per Gram Calculation

Details: Knowing the cost per gram helps in budgeting for 3D printing projects and comparing filament prices across different brands and spool sizes.

4. Using the Calculator

Tips: Enter the total price of your filament spool in dollars and the spool weight in grams (default 1000g for 1kg spool). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical price range for PLA filament?
A: PLA filament typically costs $0.02–$0.04 per gram, or $20–$40 per 1kg spool.

Q2: Why calculate price per gram instead of per spool?
A: Price per gram allows accurate cost comparison between different spool sizes and brands.

Q3: Does this include shipping costs?
A: No, this calculates only the material cost. Include shipping separately if needed.

Q4: How does filament color affect price?
A: Specialty colors (glow-in-the-dark, metallic) may cost more than standard colors.

Q5: Should I include the spool weight?
A: No, use only the filament weight (most manufacturers provide net weight).
