Hyundai Installs Two ExOne VX1000 Printers for Full-Scale Car Parts

Most automotive 3D printing still lives in the prototype lab. Parts get printed at reduced scale, or in pieces, and the real work of validating a design waits on machined tooling anyway. Hyundai's Namyang R&D Center just took a step past that stage with two VX1000 HSS printers from ExOne Global Holdings.

What the VX1000 Brings

The VX1000 uses High Speed Sintering, a powder-bed process where an infrared-absorbing ink is jetted selectively onto PA12 nylon powder before an IR lamp fuses the printed areas. The build volume is the headline: 1,000 x 550 x 190 mm, enough to print genuinely full-scale automotive components as single pieces rather than assemblies.

Consistency at that size is the hard part. Thermal variation across a meter-wide powder bed can wreck part properties, so the machine leans heavily on temperature management, with a printhead packing 8,000 nozzles laying down ink precisely across the whole volume. ExOne has also designed the wear items (the sintering emitter and print modules) as routine swap-out tasks, and both printers pipe process data in real time into Hyundai's existing monitoring systems. A shared unpacking station and central powder supply feed both units.

Why Hyundai Wants It

Namyang's newly formed Additive Manufacturing Solutions team has a wide brief: pre-production and test parts, small-batch production, research prototyping, and something every car maker knows too well, urgent sourcing of components that would otherwise need dedicated tooling. Tooling lead times are the silent schedule killer in vehicle development. Printing the functional part directly compresses design iterations from weeks to days, according to ExOne.

The installation slots into a bigger consolidation at Namyang. Last month Hyundai opened its Additive Manufacturing Solution Center, the first facility it has built specifically for AM, running everything from vat photopolymerization to DED-WAAM for large structural metal parts. Every component produced there is benchmarked against production-equivalent standards: dimensional accuracy, tensile strength, bending stiffness, and impact resistance. The VX1000s fill a specific gap in that lineup, adding large-format polymer sintering at a scale and throughput the other processes cannot touch.

The Prototyping Trap

The contrast with Jaguar Land Rover is telling. JLR's Additive Manufacturing Centre at Gaydon runs 20 industrial printers across six technologies, with polymer powder bed fusion making up 87% of its capability. Yet the center's own specialists describe most of that output as functional prototyping for test cars, not production-equivalent validation at full scale.

That is the trap Hyundai is trying to avoid: buying serious machines and still using them like expensive mock-up shops. Printing a door-panel-sized component as one piece, then testing it against production benchmarks, is a different workflow with different payoffs. If it works, the Namyang center becomes less of a lab and more of a shortcut around the tooling queue.

Car makers have talked about additive manufacturing on the factory floor for a decade. Hyundai's bet here is narrower and more useful: skip the factory floor for now, and use large-format sintering to make the development process itself faster.
