The request
Schaffner needed a robust, bespoke anti-vandal bar device to protect sensitive equipment. The aim was to design a security bar able to withstand break-in attempts while meeting precise design and manufacturing constraints.

Client's need
The need
Beyond strength and durability, this anti-vandal bar had to adapt to its installation environment (dimensions, fixing points, aesthetic constraints) and offer enough resistance to deter any malicious act. The client was looking for a reliable solution, produced quickly and at a controlled cost.
Our objective
- Design a bespoke model meeting the mechanical and aesthetic specifications.
- Prototype quickly to validate the geometry and robustness before going into production.
- Ensure a local, responsive manufacturing process through 3D printing.
Our response
Design & prototyping
We began with a study phase to understand the constraints of the operating environment: Sketches: analysing the requirements and developing several shapes for optimal reinforcement. 3D modelling: creating a virtual prototype to fine-tune the geometry, anticipate the fixing points and check compatibility with the existing supports.
Bespoke 3D printing
Once the prototype was validated, we launched the 3D printing of the anti-vandal bar mounts:
- Durable materials: selecting a high-strength filament (fibre-reinforced composite) to maximise mechanical resistance and limit wear.
- Parameter optimisation: adjusting the wall thickness and infill density to reinforce strength.
Testing & validation of the results
Before delivering the anti-vandal bar mounts, several checks were carried out: Resistance tests: verifying the ability to absorb impacts and pulling forces. Finishing: smoothing and touch-ups to guarantee a uniform surface while keeping a professional appearance. Final validation: client sign-off after confirming that the bar fits the installation perfectly and meets the anti-vandal requirements.
Conclusion
Security, tailored to the field
A device designed to measure for its installation environment, prototyped then manufactured in composite. Robust where it counts, adjusted to the millimetre.
