### Current 3D Printer Design Log
For the outerframe of the design, I am starting with the Hypercube Evoution design which has a boxed construction that has been tried and tested for rigidity and stiffness. The boxed frame is also easier to enclose which is necessary for printing ABS that requires a controlled temperature environment for good layer adhesion. The design also uses the CoreXY mechanism wwhereby the motors for the X and Y axis are fixed to the frame, which makes the X carriage that carries only the print head lighter than a conventional Cartesian design which has to carry the X axis motor. This should allow higher accelerations and printing speed.
Scott3D the original creator of the Hypercube Evolution design has uploaded a parametrized and configurable CAD file in Autodesk Inventor. This needs some modifications since the parameters don't work correctly in the original file. This is a good starting point but later designs will be carried out in Fusion 360. For now a build volume of 300cm3 will be used to build the first iteration. The current design with two / motors
Part of the design criteria is to fit the power supply and electronics under the base. This means a taller machine but it has a clean look with increased safety by keeping electronics out of reach of (kids). Moreover, transport is easier and the printer can be easily placed on a desk. The board I haven't decided on a mounting solution for yet. It may live under the machine as well with a fan ducted to outside the frame but I'm still working on the basic mechanical design so I haven't gotten to the electronics yet. The frame is being designed with the intent of closing it off so I can print with whatever I want. I haven't decided on hinged or fully removable panels yet though.
