Intro: 
3D Bioprinting Spotlight on the Green Pill.  This is Paul Gordon.  Need a heart?  No problem, let’s just 3D bioprint that right now.  A new breakthrough in bioprinting could move that scenario from sci-fi to fact.  That’s what we’re talking about on this 3D Bioprinting Spotlight, 3D Printing Artificial Tissues on Demand
Main:
A study coming out of UCLA is suggesting that we may soon see bioprinting of artificial tissues on demand.  According to UCLA bioengineer Ali Khademhosseini and his team of researchers, they have discovered bioprinting techniques that use stereolithography and a 3D Printer that Khademhosseini himself designed.  
Khademhosseini stated in the study, which was  published in Advanced Materials, “Tissues are wonderfully complex structures, so to engineer artificial versions of them that function properly, we have to recreate their complexity.  Our new approach offers a way to build complex biocompatible structures made from different materials.”
The 3D printer has two unique elements to it that make it stand out from other Bioprinters.  One feature is a microfluidic chip that features multiple inlets which allow it to print different materials.  The second feature is a digital micromirror, which is comprised of over a million mirrors, each of which are capable of moving independent of the other mirrors.
Various types of hydrogels were formed into scaffolds that provide the structure for tissues to grow upon.  The micromirrors then direct light onto the surface of the structure,  The light gives form to the structure being printed.  But the light does more than that, it also activates bonds between molecules to form, which converts the gels to solid materials.
The mirror array then directs the form of each printed layer using light patterns.
