If the PrintrBot Jr is the smallest 3D printer, then the Rostock Max is the largest.
This Rostock Max is only available in kit form. The
shopping cart states the main construction material as wood.
It is not. It's 1/4" melamine coated MDF (medium density fiber
board). For an extra $175, you can get it in acrylic.
The extruder/hot end is stationary and sits off to the rear
of the machine. The table is also stationary. The three
extruded aluminum legs act as rails for custom ball bearing
runners that attach to three plastic arms. These three arms
come together in the center and form a delta robot platform
that can move in any direction very quickly. The platform holds
the hot end that is connected to the extruder through a thin
tube that acts as a bridge for the filament.
The printer (shown in Figure 8) has a printing area of 11"
diameter with a maximum height of 14-3/4". It comes with an
11" heated bed and can extrude PLA, ABS, PVA,
Rostock Max Controller
The Rostock Max uses a Rambo controller shown in
Figure 9. This is one of the most powerful 3D printer boards
available. It comes with five stepper controllers, so you can
upgrade the Rostock Max to a dual extruder printer. It also has
extra fan outputs and temperature inputs for fans to keep the
The board comes with a special version of Marlin firmware
installed, but must be upgraded before you can use the
printer. This means you need to download the Arduino IDE
and proper firmware. You can get more information about the
Rostock Max at
The leading developers of Marlin are currently
EvdZ and bkubicek, though many others
contribute with their patches. This is a firmware
for reprap single-processor electronics setups.
It also works on the Ultimaker PCB. It supports
printing from SD card+Folders, and look-ahead
trajectory planning. This work is licensed under
the GNU GPL v3 or (at the user's discretion) any
later version. It is based on Sprinter firmware,
which was licensed under GPL
v2 or later.
