Here is a bit more on the process from the article:

Unlike conventional 3D printing, which prints in layers, their printer continuously forms a new object. As a result, they say, it’s much faster than conventional 3D printing, taking minutes instead of hours.

This could finally bring the big advantage of 3D printing — that it lets you easily customize or tweak designs by making changes to software, rather than building new manufacturing machines — to mass consumer products.

How “continuous” 3D printing actually works

There are a few different types of existing 3D printers, but they mostly work via the same principle: a printing head passes over a platform over and over, depositing layer after layer of a material like plastic in a precise pattern. Over time, these layers combine to form the desired object — much like a paper printer forms text on a page by putting down row after row of ink.

This sounds really cool and am looking forward to seeing more from the industry in general!
