Scientists make tough biogel structures with 3-D printer

1 post in this topic

BOSTON, June 1 (UPI) -- Material scientists at MIT have created tough biocompatible materials, called hydrogels, using a 3-D printer. Like a super strong sponge, the hydrogels are soft, wet and intricately patterned.

The structures feature water-soluble molecules encased in rubbery polymer strands. The strands are organized in woven networks and layered, creating a robust and tough material with a variety of real world applications.

Because the biocompatible hydrogels resemble cartilage, their most obvious use are in the medical field, either as a drug-delivery system or tissue implants.
