Exafuse public case context

Duisburg Bridge Components: large-part LMD from CAD adaptation to evidence planning

A public infrastructure project needed large structural nodes and handrail components to move from a sculptural design intent to a manufacturable, inspectable LMD route.

Exafuse owns the company case and commercial route. Manish Sharma Lab uses this public context to explain a decision pattern, not to claim project execution, engineering approval, or certification.

Public route

The physical context and decision route

Industrial context

Large structural metal components for a pedestrian bridge in Duisburg.

Public process route

CAD adaptation, deposition-path development, long-duration LMD production, monitoring, finishing planning, and project-specific validation support.

Material context

The public case is about scale and route development; it does not publish a transferable material-acceptance basis.

Verified public facts

Facts with source and limit attached

These figures are public case context. They are not transferable commitments, acceptance criteria, or proof of another component’s feasibility.

Documented components
750+ kg

Project scale context only; it is not a quality approval or a transferable feasibility claim.

Exafuse source
Structural nodes
6 nodes

A project count, not a claim that another structural component is approved.

Exafuse source
Single-node build
219 h

Project build-duration context only; it is not a productivity, scheduling, or cost commitment.

Exafuse source
Six-node robot path
38 km

Path-length context only; it is not a transferable process-capability claim.

Exafuse source
Monitoring context
1M+ melt-pool images

Monitoring data supports process understanding; it does not prove final part quality by itself.

Evidence and validation

What the evidence needs to resolve

The public record describes independent project-specific validation support and makes clear that another structural application needs its own engineering, inspection, and acceptance route.

The public case connects long-build monitoring and process analysis to production evidence without presenting monitoring as final approval.

What this public case demonstrates

Useful public context—without stretching the claim

  • A public large-part LMD project can be described as a connected CAD-to-production route.
  • Public monitoring context can support an evidence discussion when its inspection boundary remains explicit.
  • Complex, high-value components need a planned validation path rather than confidence from deposition alone.

What it does not demonstrate

  • It is not a blanket approval for another bridge or safety-critical component.
  • It does not replace structural engineering, inspection, certification, or customer acceptance.
  • It does not make the public production figures a commitment for another geometry or material.

Manish Sharma Lab interpretation

Use the case to improve the next question

This public case context is used here to explain an evidence-aware decision pattern. It is not a statement of personal ownership of Exafuse's project execution.
