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.
MDF Thickness vs Cutting Speed & Wattage
| Thickness | Recommended Power | 50W CO2 Speed | 80W CO2 Speed | 130W CO2 Speed |
|---|---|---|---|---|
| 3.0mm (1/8" Draftboard) | 70% | 15 mm/s | 24 mm/s | 42 mm/s |
| 4.5mm (3/16" MDF) | 80% | 9 mm/s | 16 mm/s | 28 mm/s |
| 6.0mm (1/4" MDF) | 90% | 5 mm/s | 10 mm/s | 18 mm/s |
Frequently Asked Questions
Why does MDF produce more soot than natural wood?
MDF is composed of compressed wood fibers bound with urea-formaldehyde or phenolic resins. Vaporizing the resin binder produces heavy sticky smoke requiring high-pressure air assist and frequent mirror/lens cleaning.
How to seal MDF edges before laser cutting?
Spray MDF sheets with shellac or sanding sealer before laser cutting to prevent soot absorption into the porous core and make post-wipe cleanup instant.
