1. What is Cost of PLA Filament per Gram?

Definition: This calculator determines the cost per gram of PLA filament based on the total price of a spool and its weight.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_g \) — Cost per gram ($/g)
• \( P_f \) — 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 Cost Calculation

Details: Knowing the cost per gram helps in comparing different filament brands, estimating project costs, and budgeting for 3D printing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical cost range for PLA filament?
A: PLA filament typically costs $0.02-$0.04 per gram, depending on brand, quality, and color.

Q2: Why calculate cost per gram instead of just spool price?
A: Different brands sell different spool weights, so cost per gram allows direct comparison.

Q3: Does this include shipping costs?
A: No, this calculator only uses the filament price. You may want to include shipping for total cost analysis.

Q4: How do I find the filament weight?
A: Check the product specifications - standard sizes are 500g, 750g, or 1000g (1kg) spools.

Q5: Does this account for empty spool weight?
A: No, this assumes the listed weight is for filament only. Some manufacturers provide net weight.
