Since FDM requires no tooling, design revisions are easily added in the following iterations when neighboring subassemblies are modified.
New surrogates are easily created according to the last design revision. The thermoplastic surrogates are also lightweight and non-marring, making installation easier and reducing the possibility of damage to nearby components.
Surrogate Configuration Options:
- Envelope Verify fit (space claim) and access for installation and service. – Basic: simplified representation that eliminates non-functional features. – Advanced: Complete representation for assessment of functional clearances (e.g. sway and cooling zones).
- Interface Validate routings and connections (e.g., fluid fittings and electrical connectors). – Integrated: interfaces constructed in surrogate. – Hybrid: production hardware mounted to surrogate.
- Ergonomic Represent weight and balance in training aids. – Ballast: add sheet, bar or shot material to surrogate.
- Smart Integrate feedback devices for surrogate detection and data capture. – RFID: encapsulate or attach tags for surrogate identification. – Sensor: embed or attach measurement devices.
