Product Description

This 6th in the series of joint Special Interest Group (SIG) meeting between euspen and ASPE on Advancing Precision in Additive Manufacturing is crucial to putting additive manufacturing onto the factory floor. Advancing Precision in Additive Manufacturing SIG was held 16th – 18th September 2019, Ecole Centrale de Nantes, Nantes, France.

The proceedings cover a wide range of topics which include :

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 Precision

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