The AM Density Deception: Navigating Risks in Parameter Development

Density plays a key role in additive manufacturing (AM) parameter development. However, in a recent study, we uncovered how even for samples above 99% density, mechanical properties can vary significantly, with our samples showing almost 20% variation for ultimate tensile strength and more than 45% for yield stress. 

Due to time and cost restraints, standard processes for parameter development tend to rely heavily on density in the first stages, with mechanical properties only being brought in once the down-selection of parameters have been completed. However, with the initial data shortages, surprisingly misleading results, and unexpected material behaviour uncovered in our study, this approach exposes users to costly delays and stifled innovation potential.

So, what does this mean for “best practice” in AM parameter development? Join AMS CEO, former Airbus engineer, and all-round AM expert, Rob Higham, and materials scientist and Plastometrex CTO, Dr Jimmy Campbell, at 2pm BST on the 21st of March as they discuss the challenges of parameter development, how the findings from their recent study could present an opportunity for users, and whether a change in approach could work in practice.

This webinar will cover:

• The challenges with current parameter development best practice, including the risks associated with reliance on density.
• Real-world examples of these challenges and their impact on the product development process.
• The findings of our recent joint case study with AMS and how these findings may influence current best practices.
