3D Printing & Additive Manufacturing Power Supplies

Delivering multi-rail architectures that separate high-current chamber and bed heaters from motion, laser, and control electronics, preventing thermal switching transients from reaching sensitive rails.

Engineering thermal derating for operation inside enclosed heated chambers, holding rated output at elevated ambient where conventionally derated supplies fail or shut down mid-build.

Providing hold-up and controlled-shutdown behavior that protects multi-day builds and preserves recovery state, eliminating the scrapped powder, machine time, and rework a single disturbance causes.

Engineering load sharing and parallel operation for industrial-scale and multi-laser platforms, with redundancy where a single supply fault cannot end a production build.

Horizon PSS takes ownership of compliance documentation and qualification testing:

Meeting EN 60204-1 requirements for protective bonding, control-circuit isolation, and correct power behavior within your emergency-stop architecture.

Supporting UL 508 industrial-control requirements for spacing, clearance, and fault-condition compliance.

Passing conducted and radiated emissions and immunity testing through architecture-level filtering, isolation, and grounding, addressing IEC 61000-6-2 and 61000-6-4, with CE technical-file inputs for the power subsystem.

Supporting laser and electron-beam platform safety architecture, including interlock and enclosure-safety power behavior your IEC 60825-1 or equivalent certification depends on.

Providing high-current DC power for heated beds, build chambers, and extruder heaters, holding regulation through resistive thermal cycling across the full build duration.

Delivering low-noise, isolated rails for galvanometer scanners, recoater and gantry motion, and closed-loop melt-pool and thermal monitoring, where switching artifacts degrade layer accuracy and process data.

Supplying stable, regulated power for laser sources and their drivers with controlled ramp behavior and defined ripple characteristics.

Engineering sealed and conformal-coated configurations for environments with conductive metal powder, inert-gas atmospheres, and continuous vibration.

Supplying qualification and traceability documentation that supports part-level process validation for regulated end markets.

Defining specifications, compliance pathways, and schedules before commitment through transparent NRE structures covering build-cycle thermal characterization, rail-by-rail load profiling, and derating verification at chamber ambient.

Ensuring the supply qualified against your build profile matches production units identically through configuration control and PCN discipline.

Providing advance notification of changes affecting form, fit, function, or compliance across long additive platform lifecycles.
