Whitman hinted at much more rapid print speeds, while also increasing accuracy. This is not really possible with existing technologies, so what might they be doing instead? One of the technologies being used in some of HP’s higher-end 2D printing devices is Memjet Waterfall Printhead Technology.
Made by Memjet and embedded into HP printers, the printhead is capable of printing ink 223mm wide at a rate of 305mm per second. Yes, that’s per SECOND. In other words, it can put out a new page in less than a second. The ink “falls” from 70,400 microjets in the printhead onto the paper streaming by below, yielding 1600dpi resolution. Watch the video here to see exactly how fast this device can deliver ink:
But that’s paper, not 3D printing.
