From the headline, I assumed this was going to be an MIT writeup of Inkbit. Instead it seems to be another MIT group but at the opposite end of the quality spectrum (this is low-ish quality but super fast, while Inkbit is high quality and yet fast). Cool!

#22Sweet. Let’s see a benchy.
They should compare speeds printing benches.

More info on inkbit please.

#24I've got a design for a printer that should be about 10,000 times faster than this. It's really a game of data transfer speed. How fast can you transfer information about solid vs non-solid into space? The velocity and acceleration of that printer is very impressive, but maxing out the movement speed of a single physical nozzle is not going to get us where we need to be in the future. If anyone is interested in colla…
Can you give us an outline?

#25How does this compare to Carbon? https://www.carbon3d.com/
That's a good question because at the moment Carbon printers are the fastest and (most important) produce production ready materials.

Sure, the basic idea is to separate data transfer from what I call locking. Data transfer can be done quickly, then locking can happen passively at whatever rate it needs.
Data transfer can take many forms. A simple example is an array of needles,pointing downward, forming a horizontal plane. The plane of needles is withdrawn upward through a granular material and dropplets of glue bind the material only where it should be hardened. In this example there is a resolution tradeoff, but you can see that the "printing" is basically completed in one pass of the plane through the print volume.
Holographic processes could transfer data to the entire volume at once.
The key is looking at the problem as a data transfer problem. We are very good at moving data very quickly.

The number of pins in such a design would dictate your surface roughness. Where would you be loading the glue from, if they're also being drawn through the binder.
Also, glue doesn't set instantaneously. I can see only problems with this approach?

Cool thinking! The linked printer can be seen as optimized for serialized throughput, whereas in the end the total amount of data transferred is what matters.
So parallelize!
Are there FDM printers with multiple nozzles extruding in the same plane? That seems like an obvious incremental step from regular single nozzle printers.

#30If you could have a liquid 3D printer below the starting surface and a solid PLA printer above, you could start in the middle of the object and print into two directions, at twice the speed. Of course- the basic question remains, what holds the middle? Retractable titanium bolt?
