Flexible resins have a problem: printed pieces tend to harden over time, sometimes within just a few weeks. AmeraLabs, a European-based resin manufacturer, claims to have solved the problem.
“Most flexible resins are a compromise – they start soft but gradually harden over weeks or months,” said Andrius Darulis, co-founder of AmeraLabs, in a press release. “We developed FLX-300 to maintain its properties over time. This opens up real engineering applications, not just temporary prototypes.”
FLX-300 features an exceptionally low compression set, enabling printed parts to reliably spring back to their original shape after repeated deformation. AmeraLabs’ internal testing showed no measurable change after three months of aging, making it suitable for long-term use in engineering and functional applications.
