AmeraLabs introduces elastic 3D printing resin with long-lasting squish — a full bottle is priced at $140

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.”
