    The first print there was made on a polycarbonate sheet, which is how every Reprap attempt that I know of has done it. There are some disadvantages to it though.

    Today however, Joe had the great idea of printing a single layer of polycarbonate to the glass heatbed with one head and then swapping it out for the PEEK head for the actual print. Of course, the polycarbonate needs all kinds of tricks to get it to stick as well, so the print bed ends up as kind of a seven-layer-dip of 3D printing.

    Glass, then Kapton, then hairspray, then Polycarbonate, then you can print.

    EDIT: In case you were wondering what that cylinder with divots is about, it's an experimental clip-on insulator cap for the melt chamber of the lower-temperature MK1, here's a picture of it cleaned up and installed on one of our newer MK1 heads.

    Impressive. Getting that right must have taken some trial and error.

    Thanks. Everything around here takes some trial and error. On good weeks, much more trial than error.
