Stratum 400 3D Printer

A custom 3D printer design using triple belted Z and custom coreXY. A Kelvin style kinematic coupling is used, and designed to use commonly available, and mostly printed parts. The printer has 8kg of filament storage, inside and enclosed chamber, as well as a separate electronics bay. The print volume is 400x400x450mm

This upload includes CAD assemblies as well as all the printed part STLs, and BOM for purchasable parts. PDF drawings are available for the printbed and extrusion cutlist.

Every printer part can be printed on a 256mm^3 printer. The entire enclosure itself is composed of many small parts, and creates mostly a frame from acrylic panels to create a heat chamber.

This printer works with a Kelvin style kinematic coupling. You may be familiar with other printers like the Ratrig using a Maxwell type, but the Stratum uses a Kelvin, because it allows increased contact surface area, an allows the user to print and use more of the critical parts without excess or rapid wear.

This printer also has unique coreXY system. Unlike many other coreXY designs, this printer drives and tensions the entire belt from one position. This way, 4 bearing sets can be removed from the printer

This is not a final function printer design. This is a highly experimental printer at this stage, so expect a fair bit of tinkering at this point.
