The joint meeting between ASPE and euspen on Dimensional Accuracy and Surface Finish in Additive Manufacturing will be in Raleigh, North Carolina at the Marriott Raleigh City Center. The Marriott Raleigh City Center is located in the heart of downtown Raleigh within easy access to restaurants, brew-pubs, visual and performing art venues, museums, boutiques, parks and city and state government.  North Carolina State University is just minutes away.

This series of Topical Meetings on dimensional accuracy and surface finish is crucial to putting additive manufacturing (AM) onto the factory floor. We are seeking papers in the following categories:

Dimensional Accuracy and Surface Finish from Additive Manufacturing (AM)

  • State-of-the-Art – What level of precision is achievable today?…and what developments are underway? …or are needed?
  • New commercially-available technologies for achieving precision
  • Prediction & modeling of dimensional errors and surface topography

Design for Manufacturing

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

Lattice Structures and Synthetic Materials for Precision Applications

  • Developments in fabricating lattice structures with high strut integrity
  • Measurement of 3D strut dimensional accuracy

Characterizing the Performance of AM Machines

  • In situ process monitoring, e.g. melt-zone temperature and 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 Holistic Manufacturing Process

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


  • Surface roughness and contour measurements on rough contoured surfaces
  • Dimensional metrology of internal features using computed tomography
  • Assessing measurement uncertainty
