Mine and Mark's printer build

Our Prusa Mendel I3 machining and building process

I’m not going to go through the entire build process but here are some photos and notes on various parts of the build.

All machining was done Mark's mill and lathe.

Here is a test print bed bracket made out of wood, it has mounting points to bolt straight onto four 8mm pillow blocks.

Once the jig for the mill was tested and proven to work we made it out of aluminium.

These are the mounting blocks/ corners for the y axis frame.

They have 10mm holes for M10 stainless threaded bars and 8mm holes for the 8mm stainless round rails.

Y axis assembled

Brass trap nut being turned down on the lathe to fit an SK16 rail shaft guide as it was originally 20mm...I think.

One side of the Z and X assembly

8x1.5mm trap screws and brass nuts much less play and friction than standard threaded bars and nuts.

 

Test rig for Z axis

X axis brackets

Printhead assembly

 In the end the main body of this was made out of three separate bits.

This has been changed since but that's something for another day.

And as you already know here is the finished product...ish.
