Research & projects

Research for industrial metal additive manufacturing.

Exafuse discusses publicly funded projects, collaborative research and development themes here without publishing confidential project data.

LMD process monitoring and melt-pool signal view

Public collaborative project

BreitbahnDED investigates wider LMD tracks and their industrial validation.

The work focuses on rotating multispot optics, wider deposition tracks, process stability and the validation needed before industrial use.

BreitbahnDED research process visual

BreitbahnDED

BreitbahnDED investigates wider LMD tracks and their industrial validation.

  • investigate wider and more uniform DED/LMD tracks
  • evaluate productivity together with the process window
  • plan validation before industrial use

Public collaborative project

EIS-KW investigates additive tooling concepts and heat management.

The project considers additive manufacturing across process boundaries: SLM/LPBF for compact functional geometry, LMD for local material addition, and combined process chains with finishing and inspection.

Additive tooling route

EIS-KW investigates additive tooling concepts and heat management.

  • investigate SLM/LPBF for compact functional geometry
  • consider LMD where local material addition is useful
  • evaluate manufacturing, finishing and inspection together

Research work

Collaborative projects and process data answer different engineering questions.

Collaborative projects examine new manufacturing approaches within a defined scope. Monitoring and data work deepen process understanding; both still require application-specific validation.

Understanding maturity

Research evidence moves toward an application in distinct stages.

The stages distinguish research direction, demonstrator evidence and part-specific qualification. They are not certification or acceptance grades.

  1. 01
    Research question

    Define the objective, measured variable, material or process question and unresolved assumptions.

  2. 02
    Representative trial

    Use a coupon or demonstrator to examine the approach under defined conditions.

  3. 03
    Published project context

    Approved project results show what was observed within a specific trial or application context.

  4. 04
    Part-specific qualification

    Define material, geometry, process, finishing, inspection and acceptance criteria for the actual application.

If the material, geometry, process route or acceptance criteria change, transferability must be reviewed again.

What research makes visible

Monitoring and data work explain process behaviour, but do not replace part release.

Melt-pool and image data can reveal anomalies and make trials easier to compare. Physical inspection and agreed acceptance criteria remain necessary for release.

LMD process monitoring and melt-pool signal view

Monitoring and AI

Monitoring and data work explain process behaviour, but do not replace part release.

  • use melt-pool and image data for process understanding
  • prioritize anomalies without automatic release claims
  • interpret outputs against metallography, surface or dimensional checks

Exafuse role

Exafuse connects process development, measured data and application-specific validation.

Research results support engineering assessment. Suitability for a specific component is still decided from the part data and inspection requirements.

Image-processing path for melt-pool width measurement in LMD
Process understanding Monitoring and image data help investigate LMD, SLM and combined process chains; they do not replace part acceptance.
Validation Measured data are interpreted alongside physical inspection, metallography or dimensional checks.
Application context Transfer to a component still depends on material, geometry, functional surfaces and acceptance criteria.

Research themes

Additive manufacturing is treated as a process, material and validation question.

The work ranges from wider deposition tracks and additive tooling concepts to process signals, AI-assisted analysis and physical inspection.

Research articles

Technical articles from current research topics.

These pages explain monitoring, AI-assisted control and neural-network image processing without exposing confidential model data, process parameters or customer results.

Melt-Pool Monitoring in Laser Metal Deposition: What Process Images Can and Cannot Prove

Melt-pool monitoring in LMD is useful when it helps engineers see process behavior, compare signals with physical evidence and decide what needs closer review. It cannot by itself establish final part quality.
