Metal Additive Manufacturing Cost Calculator – with STL Upload and Pie Chart

Use the button below to upload an STL file. The script will automatically compute: Part Volume (cm³) and Part Surface Area (cm²).
You can still override those values manually if needed.

0. Upload STL

Choose .STL file:

1. Process & Material

2. Geometry & Orientation

3. Cost Factors & Parameters

4. Material Parameters (override defaults if needed)

1. Geometry Input

• Option A: Upload an STL

1. Click “Choose .STL file” and select your part’s STL.
2. The calculator reads it locally, computes part volume (cm³) and surface area (cm²), and auto-fills those fields.
3. You can still overwrite these values manually if needed.

• Option B: Manual Entry

1. Type your own Part Volume (cm³) (e.g., 50.00).
2. Type your Part Surface Area (cm²) (e.g., 200.0).
3. Enter Orientation Efficiency (0–1), e.g. 0.90 (for a 10% time penalty).
4. Enter Support Volume %, e.g. 0.25 (25% extra volume).
5. Enter Batch Size (number of identical parts per build), e.g. 2.

2. Process & Material

• AM Process (defaults in parentheses):
  • SLM (10 cm³/h, \$120/hr, 25% supports)
  • EBM (20 cm³/h, \$150/hr, 20% supports)
  • DED (50 cm³/h, \$200/hr, 15% supports)
  • Binder Jetting (80 cm³/h, \$100/hr, 10% supports)
  – You can override “Machine Cost (USD/hr)” if your machine differs.
• Material (defaults in parentheses):
  • 316L Stainless Steel (\$60/kg, 8.0 g/cm³, 10% waste)
  • Ti-6Al-4V (\$350/kg, 4.43 g/cm³, 12% waste)
  • Inconel 718 (\$300/kg, 8.19 g/cm³, 15% waste)
  • AlSi10Mg (\$80/kg, 2.68 g/cm³, 8% waste)
  – You can override powder cost, density, or waste factor if needed.

3. Cost-Factor Inputs

Fill or override as desired (defaults in parentheses):

• Energy Cost (USD/hr): \$10
• Labor Setup Cost (USD/build): \$50
• Labor Monitoring (USD/hr): \$20
• Post-Process Surface (USD/cm²): \$0.50
• Heat Treatment (USD/part): \$30
• Support Removal (USD/g): \$0.05
• Software Fee (USD/build): \$15
• Overhead & Markup (%): 20 %

If any field is left blank or zero, the calculator uses its built-in default.

4. Calculate Cost

1. Verify geometry (auto-filled or manual), process, and material fields.
2. Adjust any cost factors if needed.
3. Click “Calculate Cost”.

The calculator will compute:

• Machine Cost = build time × machine \$ /hr
• Energy Cost = build time × energy \$ /hr
• Labor Cost = setup + (monitor × time) + (surface × post-proc) + heat treatment + support removal
• Material Cost = powder kg × \$ /kg (includes waste)
• Software Fee (flat)
• Overhead & Markup = percentage of (Machine + Energy + Labor + Material + Software)

Finally, it shows Total Build Cost and Cost per Part (spread over your batch size).

5. Interpreting Results

After calculation, you’ll see a table:

Category	USD	% of Total
Machine Cost	\$X.XX	XX.X %
Energy Cost	\$X.XX	XX.X %
Labor Cost	\$X.XX	XX.X %
Material Cost	\$X.XX	XX.X %
Software Fee	\$X.XX	XX.X %
Overhead & Markup	\$X.XX	XX.X %
Total Build Cost	\$X.XX	100 %
Cost per Part	\$X.XX	—

• Cost per Part = Total Build Cost ÷ Batch Size.
• All values computed locally—no backend involved.

---

4. Tips & Troubleshooting

• Overwrite Defaults: Any blank override field reverts to the built-in default.
• Batch Size: Use “1” for a single part build, or higher to see per-part cost spread.
