Introduction: Looking Beyond the Filament Spool

Many print shop owners price their services solely based on the cost of the filament. This leads to thin margins or losses once electricity bills, worn parts, and failed prints accumulate.

Electricity & Utility Costs

• Measuring Power Draw: How much power a typical 3D printer draws during bed heat-up and active printing.
• Calculating Cost per Hour: Factoring regional electricity rates into your hourly machine fee.

Wear-and-Tear and Maintenance Depreciation

• Consumable Lifespans: Tracking wear on nozzles (hardened steel vs brass), PEI build plates, belts, and PTFE tubes.
• Depreciation Fee: Allocating a micro-fee per print hour to cover replacement parts.

Failed Print Buffering

• Failure Heuristics: Why a 5-10% failure buffer is necessary for complex geometries.
• Pricing the Risk: Reflecting the cost of failed prints in your setup fees or gram multipliers.
