A workhorse, middle-ground GelMA for most soft-tissue work. At 175 Bloom it forms softer, more compliant gels than our 300 Bloom porcine while keeping the same mammalian source, making it a dependable everyday base.

A non-mammalian GelMA derived from cold-water fish, for models and programs that need to avoid mammalian-derived materials, including labs with religious or regulatory constraints. Cold-water fish gelatin gels and prints well at lower temperatures, which suits temperature-sensitive workflows.

Silk fibroin methacrylate

Silk-based materials for tissue engineering and regenerative medicine where mechanical strength matters.
