using gold nano-rods opens up 3D bioprinting applications
optical tweezers perhaps, that can handle very tiny things...angstrom sized tiny?

---from the article---
The 3D bio-printing market has seen significant activity in 2017. Several companies are preparing 3D printers for launch and we have frequently reported on academic studies in this area.
A number of 3D printing methods including extrusion, inkjet and patterning with lasers have been used to create scaffolds or structures necessary for cell growth.
However, the use of high-powered lasers to pattern micro/nanoscale objects has drawbacks. In particular, the substantial energy required to move material or objects means that high throughput of material is not possible.
Much enthusiasm for 3d printing of all types @everittdmickey unit.
oh yeah.
disruptive technology.
I get knowledge so thanks
