FAQ
What is build-to-print manufacturing?
Build-to-print manufacturing is a production model where the OEM or customer provides complete design drawings and specifications, and the manufacturer produces the parts exactly per those drawings. The customer owns the design, the manufacturer owns the production process. Build-to-print differs from build-to-spec where the manufacturer provides design assistance and the customer provides specifications only, and from design-and-build where the manufacturer designs and produces per customer requirements. Build-to-print is common for mature parts with established designs, aerospace and defense parts with strict customer IP control, and high-volume automotive programs.
What is the difference between build-to-print and build-to-spec?
Build-to-print: customer provides complete 2D drawings with all dimensions, tolerances, materials, and finishes specified. Manufacturer produces per drawings without design input. Build-to-spec: customer provides performance specifications and functional requirements. Manufacturer designs the part to meet specifications and produces per their own design. Most OEM-custom manufacturer relationships use build-to-print for production parts and build-to-spec for prototype or new product development.
How do you evaluate a build-to-print manufacturing partner?
Evaluate on five criteria: Quality system certifications ISO 9001 minimum, IATF 16949 for automotive, AS9100 for aerospace, ISO 13485 for medical. Inspection capability — CMM, spectrometer, optical comparators, calibrated gauges, FAI documentation. Equipment list — current model year CNC, Star Swiss turning machines, stamping presses, surface finishing capability. Tooling capability — in-house tooling design and build, progressive die stamping, CNC setup, fixture design. Supply chain depth — raw material sourcing, secondary operations, assembly, packaging, shipping.
What is the typical pricing structure for build-to-print manufacturing?
Build-to-print pricing structure: unit price based on material cost plus machining cost plus overhead and margin. Material cost: raw material cost per kg plus material yield and waste factor typically 5-10 percent. Machining cost: cycle time multiplied by machine hourly rate, typically 30-80 USD per hour for CNC, 50-150 USD per hour for Star Swiss turning. Overhead: factory overhead allocation typically 20-40 percent of machining cost. Margin: 15-30 percent for Tier 2 suppliers, 8-20 percent for Tier 1 suppliers. Annual price-down 3-5 percent common.
