MendelMax 1.5 Printed Parts Kit
MendelMax (MM) is an Open Source
printer designed by Maxbots in December 2011. It is a
true reprap, using printed brackets, but instead of using threaded rod
for the structural elements it uses inexpensive aluminum extrusions.
This gives a huge increase in rigidity for a minimal extra cost. The
required extrusions are available world wide from a variety of
suppliers. In addition to greatly increased rigidity, this design is
faster to assemble (probably 4 hours for most users), easier to print,
has a larger build volume (~215x235x190 if built at the standard
dimensions), and is easier to hack on.

MendelMax is based on the Prusa
Mendel, and keeps its best parts. The Prusa Mendel kept the
frame of the Sells Mendel, but fixed the problems in the X,Y and Z
axes. MendelMax 1.0 builds on that by largely keeping the current XYZ
axes, but completely redesigning the frame.
In addition to the increased rigidity, the printer is much easier to
assemble than a standard Prusa. Even an inexperienced builder should
have no trouble building the whole frame in an evening, two at most.
And along with the easy assembly comes easy hackability. Almost any
part on the bot can be removed with just a few screws, so swapping out
literally any part on the bot is now a trivial operation.
The X axis is taken stock from the
Prusa Mendel, in fact we don't even specify a specific X axis
design, there are several good ones available, including the various
vertically-oriented X axis designs that many people are exploring
lately. As long as it sticks to the defined standard spacing between
the Z rod and the Z leadscrew, it will work fine with MendelMax. We
also use the standard Prusa Y design (For version 1.0), though we
simplify it just a bit by making it easier to get everything aligned
right. Z adds optional thrust bearings to support the weight of the
axis (greatly reducing the problems with printed couplers), but this is
a purely optional upgrade, and you can easily use the old design if you
Because MendelMax is primarily
defining a new frame design, it is linear-bearing agnostic. I
have used both LM8UU's and PTFE bushings and both work just fine. Brass
or even printed bushings could be used, though I recommend avoiding the
latter for highest reliability.
The current revision as of July 17 2012 shipping as kits from the
official MM store is conisidered the MM 1.5+. It uses a linear slide for a Y axis rather
than polished rods to give the heaviest axis a smoother motion
and seems to have cleaned things up greatly. Also different from
earlier models the steppers controlling the Z axis have been moved from
the top of the printer to the base.
