Vacuum solutions engineered for additive manufacturing

The industry whose feedstock is the hazard — additive manufacturing handles, by design, the loose reactive-metal and polymer powder that combustible-dust standards were written to control. From receiving to loading, depowdering, sieving and reuse, the entire workflow is powder handling, and that powder is fuel. Recovery is dedicated, grounded, and HEPA-retained at every step.

Additive Manufacturing production process explorer

Every stage. Every challenge. The right vacuum solution.

An additive-manufacturing operation moves powder through a closed loop — in, into the machine, out with the part, sieved, and back again. Every transfer sheds loose powder. Walk the lifecycle where capture belongs.

Stage 01 — Powder receiving & storage

Reactive-metal and polymer powders arrive and are stored as the plant's feedstock; handling begins under inert-aware, grounded discipline because the material is combustible from the moment it is unpacked.

Key challenges

A workflow that is all powder handling

  • Reactive-Metal Powder

    Titanium, aluminum, cobalt-chromium and nickel-alloy powders are combustible metals — in AM the feedstock is quite literally fuel, handled under full combustible-metal rules.

  • Static-Sensitive Fines

    Fine metal and polymer powders build static readily — grounded, bonded, static-dissipative recovery is required throughout the powder loop.

  • Every Step Sheds Powder

    Loading, depowdering, sieving and reclaim each liberate loose powder, so capture spans the entire lifecycle rather than a single point.

  • Polymer AM Burns Too

    SLS and other polymer processes handle nylon and similar powders — combustible plastic dust with its own static behavior, not a milder exception.

  • Dedicated, Never Cross-Used

    Different powders — and metal versus polymer — are kept on dedicated recovery; mixing is both a reactivity hazard and a powder-contamination failure.

  • Asset And Hazard At Once

    Reclaimed powder is valuable to recover cleanly and dangerous to let escape — HEPA-retained, sealed capture serves both the economics and the safety case.
