The New Hotness

  • Printed Spiders

    PETG gets remarkable traction on a Prusa Textured Powder-Coated Steel Sheet:

    Gizo spider - starting build
    Gizo spider – starting build

    The Gizo spider’s eight legs built right up to the top without incident:

    Gizo spider - nearly complete
    Gizo spider – nearly complete

    The Articulated Spider assembled from many flat pieces distributed over the sheet, with no excitement at all:

    Articulated and Gizo spiders
    Articulated and Gizo spiders

    The orange parts printed in a separate operation (the eyes push in and glue on, respectively), because multi-material printing doesn’t make sense unless there’s no other way.

    Those were test cases of joint fit without any model adjustments. The Gizo prints fully assembled and, as with the Steamopus, all eight joints worked smoothly after a few careful break-in motions. Each of the Articulated Spider’s many joints snapped together without incident, but benefited from a dot of silicone grease apiece.

    With the possible exception of the PETG-CF filaments, the MK4 prints accurately enough to not need much, if any, compensation.
