1. What is Density of PLA?

Definition: Density is a measure of mass per unit volume, typically expressed in kg/m³ for Polylactic Acid (PLA).

Typical Values: PLA has a density range of ~1240-1250 kg/m³, making it one of the heavier 3D printing filaments.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of PLA is divided by its volume to determine its density.

3. Importance of PLA Density

Details: Knowing PLA density helps in material selection, weight calculations for 3D prints, and quality control of filament.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for PLA?
A: PLA typically has a density between 1240-1250 kg/m³ (1.24-1.25 g/cm³).

Q2: How does PLA density compare to other materials?
A: PLA is denser than ABS (~1.04 g/cm³) but less dense than metals like aluminum (2700 kg/m³).

Q3: Why does density matter for 3D printing?
A: Density affects part weight, material usage, and buoyancy in applications like underwater drones.

Q4: How can I measure PLA volume accurately?
A: For irregular shapes, use water displacement method. For filament, calculate using diameter and length.

Q5: Does PLA density change with color or additives?
A: Slightly - filled PLAs (wood, metal) may have different densities, but pure PLA stays consistent.
