MIT's new desktop 3D printer technology increases speeds up to 10x
[A] team of engineers at MIT have shown off a 3D printer capable of creating builds up to 10 times the speed of their consumer counterparts. According to the team, objects that take around an hour to print on conventional systems are done in a matter of minutes.
The system is built around FDM — the same technology used in most desktop 3D printers, which deposits melted plastic layers to build up a structure. MIT made some key tweaks to the print head in order to speed things up, including a screw mechanism that feeds filaments through at higher speeds by getting a tighter grip on the plastic than the traditional pinch wheel model.
The print head also added a laser near the new mechanism capable of melting the plastic much more quickly. Those pieces were coupled with a speedier gantry capable of moving the print head at a higher speed in line with the upgraded print speed.

"The only problem is, the video shows nothing of the sort. What’s more, when pushed for details, the creators of the video are now claiming the same thing."

OP is about the MIT FastFFF extrusion system, a high volume small orifice extrusion system. Hackaday's peer review was of the UMich magic acceleration and look-ahead algorithm.
The latter felt like hokum, the former an actual advance in the state of the art.
