Nano-engineers at the University of California in San Diego have developed a new biomaterial that evidently is a very close match for human tissue. This material is not a uniform substance, but is rather a particular geometry that exhibits stretching properties useful for bio-engineering.
The material is produced from a liquid polymer resin using light to solidify the resin into the appropriate material geometry in a manner very similar to how several species of 3D printers operate.
While we believe it will be a very, very long time before personal bioprinters appear, it seems that the technology to do so might be emerging.
