How 3D Printing Saved RM10,000 Per Firefighter Nozzle in Malaysia (Custom Spare Part Case Study)
· general
A single worn plastic ring inside a firefighter nozzle was forcing Bomba units in Malaysia to replace the entire RM10,000–RM12,000 nozzle assembly — because the spare part was not sold separately. 3DForger reverse engineered, redesigned, and 3D printed a direct replacement, restoring full function at a fraction of the cost. No full unit replacement needed.
When a Small Part Becomes a Big Problem
In Malaysia, many critical systems — especially firefighting equipment used by Jabatan Bomba dan Penyelamat Malaysia (JBPM) — depend on imported components sourced from overseas OEMs.
One recurring breakdown pattern:
A small plastic internal ring ("fork teeth" component) inside a firefighter nozzle fails from wear or mechanical stress
The spare part is not sold separately by the original manufacturer
The only available option: replace the entire nozzle unit (RM10,000 – RM12,000 per unit)
This creates compounding problems for fire departments:
Problem
Impact
High replacement cost
Budget strain per unit failure
Long procurement time
4–12 weeks for imported parts
Operational downtime
Nozzle out of service during procurement
Vendor dependency
No local alternative
For frontline emergency services, operational downtime is not just a cost issue — it is a readiness risk.
The Solution: Reverse Engineering 3D Printing
At 3DForger (Malaysia), we approached this differently.
Instead of replacing the entire nozzle, we:
1. Analysed the failed component (the internal ring mechanism)
2. Reverse engineered the geometry using precision measurement
3. Designed multiple CAD iterations to match original tolerances
4. Tested fit, durability, and function
5. Delivered a fully working replacement part

The result: function restored, no full unit replacement, immediate deployment.
Case Study: Firefighter Nozzle "Fork Teeth" Component
The Problem
Internal rotating or locking mechanism worn out
Original manufacturer does not supply the component as a spare part
Full nozzle unit replacement required at ~RM10,000–12,000 per unit

Our Approach
Step 1: Precision measurement The failed ring was measured using digital calipers and geometric analysis to capture all critical dimensions — inner diameter, outer diameter, tooth geometry, and surface profile.
Step 2: Parametric CAD modelling We built a full 3D model in CAD software, parameterised for iterative adjustment. This allows rapid modification without rebuilding the geometry from scratch.
Step 3: Iterative prototyping Multiple geometry refinements were printed and physically tested for:
Correct fit and seating within the nozzle body
Smooth engagement of the twist-lock mechanism
Structural integrity under simulated water pressure
Step 4: Material selection Material choice was critical. Requirements:
Heat resistance (field use conditions)
Mechanical st
