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.

How to calculate break-even on adding another printer?
Divide the printer purchase price by your average net profit per part. A $300 printer earning $15 profit per client order breaks even after 20 jobs.
