ATTENTION – EXTRUDER
The fusion and extrusion system of the thermoplastic lament requires a heated end up to tempera-
tures of 250 degrees and more. The contact, even for a very limited time, with the heated part causes
burns. You must avoid to put your hands or other body parts in the printing area when printing and
for minutes aer the printing process is over. The current temperature of the extruder is indicated on
the LCD screen.
ATTENTION – HEATED PRINTING BED
All the printing plate is made of metal with the addition of a glass plate. Shartebot NG may have a
heater at the pot’s bottom depending by which printer you decided to purchase. This device is elec-
trically heated and serves to bring to desired temperature the entire printing bed, including the glass
plate attached with pegs.
The temperature is measured directly on the heating plate: so the temperature of the glass plate
will be less than the one shown for several minutes aer the beginning of the heating process, but
likewise it may be warmer than what is indicated on the display for several minutes aer the end of
the printing due to the the phenomenon of thermal inertia. If you have the heated bed, remember
that it can be set in special cases for temperatures of 90-110 degrees, while the recommended tem-
perature for prints is usually 60-70 degrees. At these temperatures the unintentional contact does
not produce damage and burns if you retract immediately the body part that is in contact, while at
higher temperatures it greatly reduces the time necessary to create burns. You have always to check
the temperature indicated on the display before you start maneuvering like the posting of printed
piece or the removing of the glass plate on the printing bed.

Preliminar Operations
Anatomy of a Sharebot NG
Your professional 3D printer Sharebot Next Generation is a tool of precision, ideated, developed and
assembled in Italy by qualied sta. Before leaving the factory it was submitted to a quality control
and to a quality test that guarantees its operation. It’s very imporant, before you can use the printer,
knowing all the technical terms used in this handbook and identify all the specical components
that form a Sharebot NG.

Opening the package
Your Sharebot NG is equipped with a series of accessories that allow you to make it immediately
operative; there is no soware because it is open source and constantly updated. Soware must be
downloaded from the website of Sharebot to always have the latest version.
With care and without damaging the packaging remove the various parts and elements that x the
printer inside the cardboard and then, by the internal metal frame, pull it out.
Do NOT pull the so black lead from the le side and comes to the extruder: it is a power cord and
NOT handle. Proceed with the recovery from the packaging of all the parts and check that the mate-
rial listed below are all in the package:
Warning:
Do not throw away the original package. You could use it if you have to send it or move it.
In the package you’ll nd:
1. Reel-carrier in assembly kit
2. Power cable
3. SD Card with a few object that we loaded for you
4. USB cable
5. 100g of ABS and 100g of PLA
6. Spay
7. Cutter
8. Wire cutter
9. Warranty
10. Our letter of presentation and welcome
11. Glass printing bed and an object that we printed with your printer as a test
Positioning the printer
For proper operation, the printer must work in a clean and dust-free, with an ambient temperature
between 5° C and 35° c. It is also preferable to a position away from dras or air conditioning.
In the back you’ll nd power switch so we recommend to leave it easily accessible while at the front,
bottom le, you will nd the ventilation opening electronic part from which depends the correct
circuit cooling: this must be le unobstructed.
Remember that the wire is usually in a spool and that this should be positioned on the reel-carrier
included in the packaging. The recommended position is behind the printer, on the same oor, but
there are alternative positions that depend on the presence of any walls or shelves near the machine.
The important thing is that the wire is easily accessible and you can even put multiple spools on the

17
reel-carrier without any hindrances or preventing the entrainment of the wire by the extruder. For
this reason, the printer may not be placed on a shelf that is at least 35 cm free space around the rear
or side.
Assembling the reel-carrier
The two sides of the triangle shaped and coils are identical; start with the screw on a nut on one side
of the threaded bar, leaving 15mm of thread and repeat on the other side. Now insert the threaded
bar on the shoulder using the hole on the top of the triangle and x it with the nut. Do not overtighten
to avoid breaking the plexiglass. Insert the reel and attach the second shoulder. Place the door coils
behind or sideways into the printer recalling that the wire must carry out unhindered and in the di-
rection of the extruder.
Unlocking the extruder
To avoid damage during transport, the blocking of the extruder is secured with clamps. The clamps
must be carefully cut and removed to allow the extruder to move freely. DO NOT feed the printer until
you have done this step otherwise you will damage the motors and mechanics.
Remove all packaging inside the machine.
Parking second extruder
If you have purchased a NG with double extruders this operation is crucial to the success of your
prints; loosen the allen screw on the plate that connects the two carriers, we can move in parking
position (to the le) the second extruder, which will be coated in the le shoulder by a magnet. This
operation is essential to perform calibration.

Chapter 2
Process of 3D Printing
Before you start printing with your Sharebot NG it is important to understand how you arrive at a
nished object. This allows you not only to know what you need to do to give form and substance to
your ideas, but it helps you to identify any constraints and limitations of the technology used by this
printer.
In the table we summarized the steps required to obtain a 3D printing:
Model
It all starts with creating or downloading a three-dimensional model of the object that you want
to print in 3D. The creation is done through one of the many modeling programs available over the
internet as freeware, shareware or soware for a fee. There are many and each of them has specic
characteristics. In this respect it is worth noting that you can have dierent modeling requirements
and this is reected in the variety of applications. Some are more suited to mechanical design, other
artistic modeling, other than architecture.
Remember that 3D modeling was primarily used to create projects or for rendering. In the rst case
the model was thought to be accomplished physically and therefore is subject to a series of specica-
tions and constraints that allow the project to be turned into something real. In the latter, the aim is
to create an image for certain requirements: the model might then be awless as display but physi-
cally impossible.
When you choose the program that you want to use for your models you must then ensure that it is
able to create a le suitable for the production (especially 3D printing) so those programs that oer
features of rendering or animation driven.

Downloading from internet
The net oers many ready-made 3D models, but also in this case there are dierences between the
models that you “see ne” and those who “print well”. A good indicator of the ability to print the
pattern is of the form: the most popular 3D printing is STL (sites that intend to oer printable objects
use this format). If there is no STL it is likely that the intended use is dierent and the result on a 3D
printer is not guaranteed.
