On a hot June evening at a ramshackle former gliderport 30 miles east of Dallas, John Carmack's rocket engine lit up with its blue flame spewing from the nozzle.
We ran through the process a few more times, tweaking things along the way and running into new issues as we progressed -- like when the demo cube we were printing was knocked off the platform by the Stepstruder itself, or when the nozzle pressed down too hard on an object, which melted at the heat and stuck to the toolhead.

The geometry of nozzle causes the air to reach supersonic speeds and, as a result, the gun achieved a muzzle velocity of 406 meters per second, which is about Mach 1.23!

This involves shredding all of an organism's genetic material into pieces in one go by spraying it through a fine nozzle, and then sequencing the pieces without knowing where they came from.
Snyder, who spent four years on turbine engines at a Cat subsidiary, ran dozens of two- and three-week-long simulations on a minisupercomputer, crunching 10 million equations each time, to design a new nozzle that would turn insulin into the right-size droplets.

But that launch too was less than perfect, with technicians during the final days before liftoff deciding to trim off four feet of rocket-motor nozzle extensions with metal shears to address an unexpected problem with cracking.
They said that by using stereolithography, their printer could offer "layer thicknesses and feature sizes that are worlds ahead of what is possible with" the existing technique used by budget printers, which melt plastic and squeeze it through a nozzle to build up each layer of an object.
