This 5th in the series of joint Special Interest Group meeting between ASPE and euspen on Dimensional Accuracy and Surface Finish in Additive Manufacturing is crucial to putting additive manufacturing onto the factory floor.  We are seeking papers in the following categories:

1. 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

2. 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

3. 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

4. Standards

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

5. 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

6. Metrology

  • 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

The co-chairs for the joint Special Interest Group meeting between ASPE and euspen on Advancing Precision in Additive Manufacturing is John S. Taylor from University of North Carolina – Charlotte and Richard K. Leach from University of Nottingham, UK.
