MendelMax 2
Informatie (ENG):
The new MendelMax 2 is a complete reinvention of the MendelMax. It makes the MendelMax faster to build, easier to source and even better looking than before.
The MendelMax 2 includes a completely redesigned frame, made from aluminum extrusions and primarily flat plates. These plates can be cut from aluminum, printed, laser cut from plastic, or hand cut with a scroll saw or a coping saw (making this arguably the most accessible DIY reprap ever). A hand cut MendelMax 2 will virtually function identically to a custom machined one. There is no longer a reason to see your hand built machine as merely a means to an end.
Triangles are a smart choice for the gantry, both functionally and aesthetically. From a design standpoint, I wanted the MendelMax to still be visibly a Mendel descendent, while not letting the shape get in the way of improvements. By switching to a right-triangle design, the MendelMax 2.0 gains ~50mm more z-axis movement (the exact amount will depend on your extruder choice). The new design results in a very open, unobstructed print area.
