Yes. I believe acoustic dispensing will be a very big player in this industry, as it allows for much higher resolution than any syringe-based model. It is also very fast and accurate, and I believe it is gentle on cells so their viability remains high. It is a noncontact method, too!
Another technology that could be interesting uses some sort of structured illumination (like a hologram or a projection) to create the 3D shapes out of photopolymerizable biomaterials. Resolution would be much better than the syringe dispensing, and it would be a matter of finding the appropriate biomaterials and applications.
