Assembly Manual
Arduino Materia 101
We are excited that you have decided to take part in this new
industrial revolution. Like all new technology, it is pioneers like
you who will lead the real innovation. Your new Arduino 3D
printer will give you the freedom to create all the objects you
can imagine.
This machine is the latest result of the experience we have
collected through all the previous models. Your advice will help
us to improve our products and together with you, we can set
new standards for future desktop printers.
We believe that sharing is the best way to innovate so we invite
you to tell us your thoughts at www.arduino.cc
We look forward to seeing what you will create with the
Materia 101!

TOOLS:
- 2.5 Allen Key
- 1.5 Allen Key
- 3 Allen Key

NOTES
Screws could loosen because of damage or from vibration
so use threadlock on each screw that touches a metal part.
Threadlock is a liquid that fills in the gaps between the threads
of screws and hardens into a rubber like substance or glue.
We suggest Loctite 221, a low resistance threadlocker for the
some screws. You can also use teflon tape.
We suggest using sewing machine oil to lubricate the Z axis
bearings and guide rods.
Arduino’s Materia 101 Assembly Kit is meant for a user who
already has experience with assembly. The manual assumes
the user knows how to use a soldering iron.

Turn over the bottom tray again. In the
picture you will see colored areas for the
metal rod guides in grey, Z axis in blue,
Arduino Mega 2560 in orange and the
fan is in yellow.

Take the metal rod guides (4) and
pair them then attach them to the
bottom tray. Without tightening, hold
them in place with M3x6 bolts (2).
Fig. 7
You can use the Z axis D8x338 guides
to center them before tightening.
Fig. 8
Take M3x20mm nylon stand-offs (3)
and carefully tighten them. Do this
step by hand, to not damage the
nylon thread.

Lay the Arduino Mega 2560 board on
the stand-offs and secure the control
board to the base using M3x6 bolts
(3). Once again, be really careful not
to damage the nylon thread.
Fig. 10
Place the Ramps board on the Arduino’s
and connect it through the pins paying
attention not to bend it. Attach heat
sinks (4) to the motor’s driver. Inside
the kit there is another driver that could
be used as a spare part.
ATTENTION: THE HEAT SINK MUST
NOT TOUCH THE PINS.
Fig. 11
Place a 40mm fan with the label
facing downward, the cable pointed
towards the board and connect the
fan to the plug specified on the board,
as you see in the picture (fig. 11).
Paying attention to polarity, + RED –
BLACK, fasten through the threaded
holes at the center of the tray.

Remove screw no. 1 and 3 with a
crosshead screwdriver (fig. 12) from
the bottom of the tray (fig. 13).
Fig. 14 - 15
Secure the Z motor. You need M3x35
bolts (2) and o-rings (2). O-rings
are necessary to soften the motor
vibrations. Put M3x35 bolts in
position 1 and 3 from the rubber feet
side. From the other side of the tray,
place o-rings on the bolts then tightly
secure the Z motor to the bolts. The
o-rings must lie under the motor.
Remove the bar cover and unscrew
the brass nut block from the Z screw.

Place the bearings on the carriage’s
print bed side and use M4x8 bolts (4)
to secure it, as in the picture. Tighten
the M3x10 nylon stand-offs (2) on
back part (opposite to the bearings).
Be very careful since they are plastic.
Take the brass nut block from the Z
motor and tightly secure with M3x6
bolts (3) to the Z carriage.

Attach the security sticker to the
plate. The cut out must be pointed
in your direction and the two tabs
should face upwards.
Fig. 7- 8
Now insert M3x25 bolts (4) into the
printing bed, as pictured, then place
the D10 springs on the bolts and fasten
the print bed to the Z carriage. Leave
the printing bed’s cut out at one end of
the shoulder with the Z axis bearings.
You may need to use just a bit of
threadlocker between the printing bed
and the Z carriage.

To complete this step, select these
tools and parts:
—Right lateral shoulder
—Left lateral shoulder
—Stepper motor with pulley
—X axis D8x244mm guide
—LMU88 bearings (8)
—Seeger rings(12)
—Nylon bearing supports (4)
—M3x10 nylon stand-offs (2) and
M3x20 nylon stand-offs (2)
—M3x6 bolts (20)
—X axis metal rod guides (8)
—T2.5 500 belt
—M3x25 bolt
—M3 lock nut
—12mm 3x6 teflon tube
—End-stops (2)
—M3 x10 bolts (2)
—T2.5 16 pulley
Fig. 2
Take the left shoulder, fasten two
nylon bearing carriers with M3x6
bolts (4). This part must be attached
to the inside of the shoulder.
Fig. 3
If you need to, polish the holes of the
X guide carrier with some sandpaper
to ensure a good connection.
With M3x6 bolts (2) couple and
secure the 4 metal rod guides. If
needed, you may use a D8x315mm
bar to center the metal rod guides
with the shoulder hole before
tightening. After this step, test if
the guide is fully inserted into both
metal rod guides. You can do this by
pushing the second rod guide laterally
with a flathead screwdriver.
This part must not move.

Assemble the pulley pass with the
M3x25 bolt and use teflon tube.
Close all the parts with the lock nut.
Fig. 6
Place the pulley inside the belt. The
entire part must be set inside the
side shoulder. The pulley has to
be oriented with the toothed side
pointed towards the machine’s
bottom, as you see in the picture. It is
necessary to use a bit of strength.

Take LM8UU bearings (2), then using
Seeger pliers, assemble Seeger rings
(2) for each bearing.
Fig. 9
Assemble the bearing, wedging in
the nylon bearing carrier that we
assembled before on the left shoulder.
Fig. 10
Now assemble a Seeger ring for each
of four LM8UU bearings. To do this
use a Seeger pliers.
Attach the LM8UU bearings (4) with
only one Seeger on the X bars with 2
bearings to each bar. The Seeger ring
must be internally aligned.
Fig. 11
It is time to assemble the right
shoulder. Take the shoulder and
secure two nylon bearing carriers
with M3x6 bolts (4), as you did with
the left one (fig. 3). Fasten the metal
rod guides (4) with M3x6 (2) bolts
inside the threaded holes (fig 3).
Repeating the same process you did
for the left shoulder. For this one,
also use the LM8UU bearings (2) with
attached Seegers.
