1. What is the 3D Print Cost Equation?

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

2. How Does the Calculator Work?

The calculator uses the 3D print cost equation:

Where:

• \( C \) — Total cost in currency
• \( V \) — Volume of the print in cm³
• \( D \) — Density of the material in g/cm³
• \( P \) — Price per gram of material in currency/g
• \( T \) — Print time in hours
• \( R \) — Hourly rate in currency/hour

Explanation: The equation calculates material cost (volume × density × price) and adds it to the labor cost (time × hourly rate) to get the total cost.

3. Importance of Cost Calculation

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

4. Using the Calculator

Tips: Enter the volume of your print, material density, material price per gram, estimated print time, and your hourly rate. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the volume of my 3D model?
A: Most 3D modeling software can calculate volume. Slicer software also typically shows the volume before printing.

Q2: What are typical densities for common 3D printing materials?
A: PLA ≈ 1.25 g/cm³, ABS ≈ 1.04 g/cm³, PETG ≈ 1.27 g/cm³, TPU ≈ 1.21 g/cm³.

Q3: Should I include setup time in the print time?
A: Yes, if significant setup is required. For repeat prints, you might average the setup time across multiple units.

Q4: What other costs should I consider beyond this calculation?
A: Consider machine depreciation, electricity costs, failed prints, post-processing time, and overhead expenses.

Q5: How accurate is this cost estimate?
A: It provides a good baseline but actual costs may vary based on print success rate, material waste, and exact machine efficiency.
