I have in mind the design of a new type of printer. I call it the “Rail Printer” …
Imagine a typical x y z printer like the Prusa, give it 4 wheels one on each corner, remove the moving table ( the y axis) now the y axis becomes the area between the 2 rails.
This printer would be ideal for printing out things like wings for drones, fuselages and the like, really anything long and narrow.
The first problem would be the length of time to produce the print, I think this problem is solvable or at least reducible to a manageable level by adding printers. Imagine 2 or 4 or 10 printers all printing at the same time on the same printed object. Now the problem becomes how to identify accurately the position of each printer and how to divide the printing duty between each printer and how to construct a suitable join between each level.
The other interesting thing about designing a printer in this manner is you could have two printers operating on the same printed component but loaded with different materials. It may even be possible to adapt the system to print with in theory an unlimited number of materials.
I would be interested in your observations, criticisms and comments.
