Our Approach
3fD thrives under pressure — and this was no ordinary year.
With our team of electronic, mechanical, tooling, and production engineers all working remotely during lockdown, we launched a fully parallel development sprint, integrating all disciplines from day one.
Key tactics:
- Concurrent engineering: design, prototyping, and tooling development ran in parallel, collapsing timelines.
- Risk-managed decision-making: rapid iteration with clear checkpoints to de-risk accelerated development.
- Design-for-manufacture from the outset, ensuring scalability and robust field performance.
- Despite the compressed schedule, we prioritised both function and form — engineering not just a practical solution, but one with visual and structural appeal.


Engineering & DFM Decisions
- Core structure: Recycled aluminium extrusion, serving as both the aesthetic element and the rugged, fireproof chassis for the unit.
- Tap and tray design: Engineered for durability using fire-retardant plastics, with tooling optimised to eliminate stress points and extend product life.
- Tooling strategy: Rapid tooling development, configured to avoid delays despite pandemic restrictions.
- Global teamwork: Remote, round-the-clock collaboration with suppliers and tooling partners worldwide.
Outcome
- Delivered first production-ready units in just 12 weeks, from concept to field trial.
- Enabled Handi to meet surging pandemic-driven demand and enter field trials on time.
- Provided a scalable design, ready for mass production despite initial constraints.
- Maintained remote development and supplier engagement with zero in-person meetings.
What We Learned
Speed does not have to compromise design integrity.
Through parallel development and relentless focus, even extreme timelines can be met — provided risks are managed and DFM principles are applied from the very beginning.
