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.
Polycarbonate vs Other Engineering Filaments
| Polymer | Heat Deflection (0.45 MPa) | Impact Strength | Spool Cost |
|---|---|---|---|
| Polycarbonate (Pure PC) | 135°C - 145°C | Extremely High (60 kJ/m²) | $40 - $55 / kg |
| PC-PBT Blend | 110°C - 120°C | High Chemical Resistance | $50 - $65 / kg |
| PC-CF (Carbon Filled) | 140°C - 150°C | Ultra-Stiff (Low Warp) | $65 - $90 / kg |
Frequently Asked Questions
Why is Polycarbonate priced significantly higher than PLA?
Polycarbonate requires extreme nozzle temperatures (280-310°C), heated beds (110-120°C), and enclosed chambers to prevent warping, along with post-print oven annealing to relieve internal stress.
What industries buy 3D printed Polycarbonate parts?
Robotics teams, automotive prototyping, aerospace electrical housings, and drone manufacturers who require high impact resistance and 110°C+ thermal resistance.
