3D Printing With Metal — WAAM, Layer Upon Layer
Wire arc additive manufacturing builds solid metal directly from a spool — layer on layer, each weld bead the foundation for the next.
Wire-arc additive manufacturing (WAAM) is metal 3D printing at weld-pool scale: every layer is a weld bead deposited on the one before it, and every pass adds heat that the next layer has to absorb. Watching the deposition happen — bead by bead, layer by layer — makes it obvious why interpass temperature control is the difference between a dimensionally sound part and one that slumps or delaminates.
What you see
- Solid metal built directly from a wire spool, bead on bead.
- Each new layer deposited on the melt pool of the one before it.
- Heat accumulating across passes as the build grows.
- Why interpass temperature control keeps geometry and microstructure stable.
Monitor it with Therness
- HeatCam thermal sensors read layer and interpass temperature live.
- HeatCore AI flags overheating and process drift before a layer fails.
- Layer-by-layer thermal records build QA evidence for every part.
- Works on carbon steel, titanium, and nickel WAAM builds.
