While characterizing the epoxy samples mentioned earlier, we encountered a challenge when increasing the ratio of plasticizer—the DMA (dynamic mechanical analyzer) machine couldn’t break the samples. Unfortunately, our current DMA had a maximum force limit of 400 newtons. Fortunately, we had access to another DMA, albeit set up with clamps for viscoelastic materials and lacking 3-point-bending tools.

To overcome this, I designed and 3D printed adapters that could integrate with the alternate DMA apparatus. These adapters included a top piece with embedded neodymium magnets, ensuring secure attachment of the tooling without risk of dislodging. Thanks to these custom adapters, we managed to successfully conduct our research within the constraints of our available time.
