Engineering Best Practices & Pricing Breakdown
Precision job quoting in custom fabrication requires factoring in real consumable depletion, energy tariffs, operator touch time, and machine wear. Relying on simple '3x material cost' rules frequently causes custom makers to operate at a hidden net loss on complex jobs.
By capturing true volumetric yields, machine depreciation schedules, and hourly technician burden rates, this tool ensures sustainable profit margins for commercial workshops and micro-manufacturers.
PETG vs PLA Printing Cost Comparison
| Parameter | Standard PLA | Commercial PETG | Cost Impact |
|---|---|---|---|
| Spool Cost (1kg) | $16.00 - $20.00 | $18.00 - $24.00 | +15% Material COGS |
| Bed Temperature | 50°C - 60°C | 70°C - 85°C | +30% Electrical Draw |
| Post-Processing Time | 2 - 5 mins | 8 - 12 mins (Heat Gun) | +$3.00 Labor / Part |
| Recommended Markup | 50% - 60% | 65% - 75% | Higher B2B Margins |
Frequently Asked Questions
Why is PETG more expensive to print than PLA?
PETG requires higher nozzle temperatures (235-250°C) and higher bed temperatures (70-85°C), increasing electricity draw. It also prints slightly slower to prevent stringing and requires post-processing heat gun passes to remove hair strings.
What is the typical retail markup on commercial PETG parts?
Commercial functional parts (brackets, enclosures, jigs) typically command a 60% to 75% profit margin due to their structural durability and temperature resistance up to 75°C.
