This paper describes a novel 4-axis FDM printing process with a newly designed printhead, for the printing of overhangs without support structures. With conventional FDM printing, overhangs of more than 45–60∘ must be supported.
For this novel printing process, the printhead is rotated 45∘ around a horizontal axis and equipped with a vertical, rotational axis. The printhead no longer follows layers parallel to the build platform, but moves on the surface of a 45∘ cone. The printing cone increases in diameter from layer to layer. With this cone-shaped layers, the printable angles increases by 45∘, which leads to printable overhangs of up to approximately 100∘.
New slicing strategies for this printing process have been developed to slice the parts for the novel printing process. The feasibility of the concept has been prototypically demonstrated. The novel design achieves the advantages of higher speed and quality with lower cost at the same time.
Yeah, it looks like it's not fully general in that some things can't be printed. But it's pretty close. 3D printers with easily-replaceable heads are becoming more common, so I could see it...

I think I've seen this before. What fascinates me most in this isn't the printer itself but the slicing. That has to be insanely complicated.

I ordered a Prusa XL with two toolheads, let's see if this could be one of those printers. Three attachment points available for experiments.
