Successfully crowdfunded in November of last year, the Hyrel has made steady progress through development. The Hyrel can simply do things that other 3D printers cannot: there’s an (optional) onboard computer, it can print with up to four extruders, and it can be fitted with the EMO-25 for printing with clay, plasticine, Play-Doh, silicone, and Sugru. But being equipped with four extruders means more than having multicolor prints; multiple materials and objects can be printed at the same time.
All of the extruders are hot swappable, though the EMO-25s take up the space of two MK1 plastic extruders. So either up to four plastic duplicates can be printed simultaneously or two clay/silicone/plasticine. Of course, they have to be small objects, else they’ll overlap. But still, that’s four times faster than every other desktop printer. The personal factory is becoming more literal every day.
