When it comes to 3D printing using fused deposition modeling (FDM) technology, there are two main groups of printers: Cartesian and CoreXY, with the latter being the domain of those who wish to get the fastest prints possible, courtesy of the much more nimble tool head configuration. Having less mass in the X/Y carriage assembly means that it can also move faster, which leads to CoreXY FDM enthusiasts to experiment with carbon fiber and a recent video by [PrimeSenator] in which an X-beam milled out of aluminium tube stock that weighs even less than a comparable carbon fiber tube is demonstrated.
As the CoreXY FDM printer only moves in the Z-direction relative to the printing surface, the X/Y axes are directly controlled by belts and actuators. This means that the faster and more precise you can move the extruder head along the linear rails, the faster you can (theoretically) print. Ditching the heavier carbon fiber for these milled aluminium structures on a Voron Design CoreXY printer should mean less kinetic inertia, with the initial demonstrations showing positive results.
The interesting thing about this ‘speed printing’ community is that not only the raw printing speeds, but also that in theory CoreXY FDM printers are superior in terms of precision (resolution) and efficiency (e.g. build volume). All of which makes these printers worthy of a look next time one is shopping for an FDM-style printer.
