1. What is the 3D Printing Cost Formula?

The 3D printing cost formula calculates the total cost of a 3D printed object by considering both material costs and machine time costs. It provides a comprehensive way to estimate expenses for 3D printing projects.

2. How Does the Calculator Work?

The calculator uses the 3D printing cost equation:

Where:

• \( C \) — Total cost (currency)
• \( V \) — Volume of the object (cm³)
• \( D \) — Material density (g/cm³)
• \( P \) — Material price per gram (currency/g)
• \( T \) — Printing time (hours)
• \( R \) — Hourly machine rate (currency/hour)

Explanation: The first part calculates material cost based on volume and density, while the second part calculates machine time cost.

3. Importance of Cost Calculation

Details: Accurate cost estimation is crucial for pricing 3D printing services, budgeting for projects, and comparing different manufacturing methods.

4. Using the Calculator

Tips: Enter all required values in their respective units. Volume and density must be positive values. Time and hourly rate can be zero if only calculating material costs.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the volume of my 3D model?
A: Most 3D modeling software can calculate volume. Slicers like Cura or PrusaSlicer also show volume estimates before printing.

Q2: What are typical material densities for 3D printing?
A: PLA ~1.24 g/cm³, ABS ~1.04 g/cm³, PETG ~1.27 g/cm³, but check your specific material's datasheet.

Q3: Should I include electricity costs?
A: Electricity costs are typically included in the hourly rate (R). For home printers, estimate $0.05-$0.20 per hour.

Q4: What about post-processing time?
A: For complete cost estimation, you may want to add post-processing time separately to the printing time.

Q5: How accurate is this cost estimate?
A: It provides a good baseline but doesn't account for failed prints, support material, or machine depreciation.
