Dimensional accuracy and surface finish from additive manufacturing (AM)

  • State-of-the-art – What level of precision is achievable?…and what developments are underway?…or are needed?
  • Functional specifications for form and finish
  • Prediction & modeling of dimensional errors and surface topography
  • Developments in fabricating lattice structures with high strut integrity

Design for manufacturing

  • Design rules & tolerancing for additive manufacturing
  • Topology optimization in the context of AM and achieving precision
  • Novel designs for flexures or kinematic couplings

Characterizing the performance of AM machines

  • In situ process monitoring, e.g. melt-zone temp, powder bed
  • In-process measurement of workpiece shape and topography
  • Using artifacts to assess machine performance; round-robin testing
  • Holistic views of the control system, process feedback, correction


  • Certifying AM equipment capabilities
  • Industrial demands for ASTM and ISO standards

Integrating AM into a holistic manufacturing process

  • Cost-benefit trade-offs of using AM within a complex process chain
  • Engineered partnerships between AM & secondary finishing
  • Dealing with residual stress and heat treatment in a process flow
  • Kinematic tooling or pallets for repeatable part handling


  • Surface topography measurements on rough contoured surfaces
  • Dimensional metrology of internal features using computed tomography
  • Multi-sensor approaches, data fusion, and machine learning
  • Complex form measurement, registration and fitting
  • Measurement of 3D latttice strut dimensional accuracy
