new printer progress

What are 3D printers for? Printing new 3D printers! I’ve finished printing the CoreXY parts for my new printer. CoreXY is the method I’m using to control the X and Y axes (left/right, forward/backwards), using parts designed by Louis Zatak who put them on Thingiverse. He also provided parts for Z axis bed lift as well , using the same belt trick that the CoreXY uses.

The dimensions I’m printing are probably much too large – I went for 50cm cubed, which might end up with a print volume of about 44cm cubed, which is 8 times larger than my current printer (an Anet A8).

There will be problems, I’m sure – with 50cm rods, the x-carriage will probably droop near the middle. I have an idea how to solve that if it happens, but we’ll see if it’s necessary!

All that’s left to get for this new printer are some rods for the x-carriage, the y axis, and the z-axis, and a hot-bed. The hot-bed is not strictly necessary, but it will make it work much better. without a hot-bed, prints might curl upwards, and will probably have trouble sticking to the print bed.

After this is finished, I have a plan to build a brief-case sized foldable 3D printer.

The CoreXY design is compact and may be foldable, so I’m going to try find a way to have the z-axis fold upwards towards the CoreXY frame, and then fold the arms of the mechanism inwards. In my head, it works…
