There are times when visual representation, especially in a video format, can convey a concept far better than words alone. This is evident in heinz\u2019s dual-disk polar 3D printer<\/a>, which operates on an innovative inverted SCARA principle. This design allows the printer to create captivating and unconventional motion paths by moving the print bed around a stationary hot end.<\/p>\n

In this unique setup, the Z-axis runs vertically through a central column, while the print bed consists of a geared disk that can both rotate around its own center and around the central column. This structure facilitates the use of multiple extruders; they can be positioned at various angles and selected by rotating the bed to the desired extruder. As the extruder only moves vertically (in the Z direction), there’s less concern about weight compared to traditional designs. In fact, the system performed impressively with a hefty two-kilogram direct-drive extruder assembly, though this added some operational complexity.<\/p>\n

Heinz used 3D printing to manufacture the rotating disks and several other components while utilizing GT2 timing pulleys and Lazy Susan bearings for mobility. The print bed, made from fiberglass, features small holes drilled into its surface, enabling molten plastic to grip better as it prints. An interesting aspect of the rotating print bed is its ability to create a visually dynamic turntable effect<\/a> during time-lapse capturing.<\/p>\n

This isn’t the first time we’ve highlighted this project; we previously mentioned it during its earlier stages. The recent upgrades have certainly impressed us! While polar 3D printers can complicate the visualization of printed paths, they offer exciting capabilities like multicolor printing with four extruders<\/a> or non-planar motion<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
