The instructions state that you will
need 1-2 hours to complete the build.
I suspect this estimate was from
someone who has built the machine
several times. My estimate is more in
the order of 4-12 hours.
The instructions will take you
through the assembly of the base
(Figure 5), table platform (Figure 6),
and the main arm (Figure 7).
The extruder shown in Figure 8 is
used on several of the Printrbot 3D printers. For this reason,
it has its own assembly instructions.
The controller board is installed next. You will connect
the various connectors to the board (Figure 9), and then
install the board into the base as shown in Figure 10.
