Professors Jamison Go and John Hart of the Massachusetts Institute of Technology (MIT) Mechanosynthesis Group have developed new hardware that enables what they call FastFFF (fast fused filament fabrication). And it’s fast, see for yourself.
Desktop 3D printers are fantastic at creating high-quality and complex parts on demand, but their greatest weakness has always been speed. They can only print one object at a time, one thin layer at a time. And there are several speed-limiting factors to FDM/FFF 3D printers, with the main four being: the amount of force that can be applied to the filament as it’s pushed through the nozzle, how quickly heat can be transferred to the filament to melt it, how fast the printhead can move around the build area, and the rate that the material solidifies after it’s extruded because it needs to support the next layer.
