Case study
3D-printed mechanical mounting bracket: case study
A mounting bracket built to validate load, fastening, and in-service behaviour before moving to industrialisation — material and layer orientation matched to the main stresses.
The initial need
Hold a sub-assembly in place with repeatable clamping constraints, without over-sizing the first version.
- Context: integration on an existing plate, standard tool access.
- Problem: validate geometry and holding before batch or metal part.
- Constraints: clamping force, moderate vibration, extended test duration.
What we did
Material: PETG for a good stiffness / process balance on the functional version; layer orientation aligned with the primary loads.
Design: ribs, holes sized for screws, fillets to limit stress concentrations.
Method: FDM with settings suited to clamping; fit adjusted after first assembly.
Outcome
Bracket validated under representative conditions — enabling a clear decision on next steps (batch, different material, or process).
