2022 Summer Topical Meeting
Advancing Precision in Additive Manufacturing

Dimensional accuracy and surface finish in
additive manufacturing (AM)
• State of the art: What level of precision is achievable?
• Functional specifications for form and finish
• Prediction and modeling of dimensional errors and surface topography
• Developments in fabricating lattice structures with high integrity
• Diversity in scale of features: large-scale–to–micro-nano
• Precision in the broader AM context: PBF, FFF, DED, WAAM, TPL, etc.

Design for manufacturing
• Design rules and tolerancing for AM
• Topology optimization in the context of AM and achieving precision
• Novel designs for flexures and kinematic couplings
• Metallurgy and fatigue issues in high-cycle precision applications

Characterizing the performance of AM machines
• In situ process monitoring, e.g. melt zone temperature, 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
• Machine learning to conquer the complex AM parameter space

• Certifying AM equipment capabilities and material properties
• Industrial demands for ASTM & 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 and secondary finishing
• Kinematic tooling or pallets for repeatable part handling

• Surface topography measurements on rough as-built surfaces
• Dimensional metrology of internal features using computed tomography
• Multi-sensor approaches, data fusion, and machine learning
• Complex form measurement, registration, and fitting of point clouds
• Measurement of 3D lattice strut dimensional accuracy and integrity
• Characterization of internal defects and voids
