1. Base. Build the base first, then you can attach all of
the remaining subassemblies to it. Furthermore, many of
the building techniques that will be used throughout the
construction of DUPe1 can be learned with this initial step.
Turning the base upside down as in Figure 3 helps to
illustrate these building techniques.
2. Z Axis. A pair of free-wheeling pulleys are
embedded inside two 12 inch aluminum channels — a total
of four pulleys are used in DUPe1; only two are assembled
in this step, however. The other two pulleys will be added
when building the Z axis trolley mount. A detailed look at

As you can imagine, a lot of
parts are needed to build a 3D
printer. The numerous parts lists
are annotated throughout this
article, as well as visually
illustrated in Figure 2. In addition
to these Actobotics components,
you will also need a 7/64” hex
key, 3/32” hex key, pliers, and
Phillips head screwdriver.
There are 10 major
subassemblies that are individually
combined into the finished 3D
printer. We will cover each of
