There is an old principle in military training: the more accurately you can rehearse, the better you will perform under stress. For decades that meant sand tables, plywood mock-ups and chalk diagrams on warehouse floors. Additive manufacturing has quietly upgraded all three.
From scaled urban terrain for company-level rock drills to dimensionally accurate vehicle-interior mock-ups, and weapon-system trainers that capture real ergonomics, printed training aids are now a routine part of the Australian Army training landscape, and the better units have noticed the difference at exercise debriefs.
The shift is not just cosmetic. Better aids change rehearsal outcomes, and the units that have invested in printed rehearsal libraries are seeing fewer surprises on operations, fewer wasted live-fire cycles, and faster onboarding for replacements rotating into the team.
Terrain models for company and platoon rehearsals
Printed terrain brings a level of fidelity that traditional sand tables cannot match. Roads, contour lines, building footprints, drainage features and key infrastructure are all modelled to scale and topographic accuracy, with modular tiles that reconfigure for different scenarios without rebuilding from scratch.
The economics now favour printing over building. A 1.5 metre square modular terrain set, painted to display standard, costs less than a week of contracted carpentry and ships ready to use on the morning the rock drill starts.
1:500 to 1:1,000 for company-level rock drills,
1:200 for platoon-level urban or compound rehearsals,
Modular tile layout so a single table covers multiple areas of operations,
ASA and PETG tile finishes that survive years in a training shed,
Painted on our airbrushing line for visual realism.
Crew and weapon-system trainers
Vehicle interior mock-ups let crews practise emergency egress, casualty evacuation and weapon-station handling without using the real platform. A foam-and-printed-fitting mock-up of a Bushmaster or LAV compartment, accurate to ergonomic dimensions, lifts drill quality immediately and frees the live platform for higher-value training.
Weighted weapon trainers with accurate controls and grip ergonomics,
Casualty extraction rehearsal aids built around real stretcher geometry,
Quick-change panels for switching between vehicle variants in a single rig,
Printed using engineering filaments from OzFDM for durability,
Replaceable wear components so the rig outlasts the course.
Mission-specific aids when the clock is ticking
When a unit prepares for a specific operation, mission-specific aids can be produced quickly: a model of the actual building, the actual route, the actual access point. Our large-format FDM platforms reach 1m x 1m x 1m and make this feasible inside a one-week planning cycle, which is the strategic value rather than the geometric novelty.
That speed has real operational consequences. A mission planner can iterate the model alongside the orders cycle, with the printed rehearsal aid in the training shed before the warning order rolls into the formal operations order.
KEY TAKEAWAYS
Printed terrain improves fidelity over sand tables at every useful scale,
Weighted weapon and vehicle mock-ups build genuine muscle memory,
Mission-specific rehearsal models compress planning timelines from weeks to days,
Engineering filaments and airbrush finishing deliver years of service life,
The capability is available now to Australian units and training contractors.
