I really did not see why people were so excited about 3D printers until today.
As a man who loves things that come out of tubes, I am excited about the Discov3ry Extruder. Designed as an add-on to popular 3D printers, the system is essentially a plunger connected to a nozzle that squirts out pastes of various types including icing, Nutella, spackle, and silicone.
The product just launched on Kickstarter and has surpassed its goal of $30,000. The extruder itself should work on most major 3D printers including RepRap machines and Makerbots. The extruder itself attaches to the standard extruder tip of the printer and then you have to set the specifications for various substances, including the aforementioned Nutella.
The extruder costs $249 for early birds and uses disposable syringes to hold the pastes. Rubber tubing carries to paste to the machine which is then pushed out like the standard plastic filament normally used by these printers.

This figure comes from a recent paper by Isacke and Barcellos-Hoff describing research by Alspach and colleagues. Their research confirms that many stromal cells that would normally hinder a tumour (for instance here) can actually help it in certain circumstances, for instance when tumour cells learn how to co-opt them or when the tumour grows in a tissue with senescent fibroblasts. It’s clear that tumour cells have to be able to co-opt and fool a lot of regular cells to succeed and although we need to know more about the genetic mutations that allow tumour cells to do that, it would be foolish to neglect the context in which these mutations emerge: the tumour ecosystem.
When the differences for the same medical services fluctuate so wildly I do not think you can say you have a working market.
