Safety and compliance
12 User Manual
General information
To avoid potential residual risks the user should read and understand the following safety measures (you are
strongly advised to read this before using the machine).
To highlight the areas where extra care should be taken, safety alert stickers have been affixed to the relevant parts
of the machine to warn the user of potential hazards.
Any modifications made to the machine without the manufacturer’s approval will invalidate the product’s
Declaration of Conformity (CE) and warranty.
Consequently, the BARCELONA THREE DIMENSIONAL PRINTERS, S.L. ARE EXEMPT FROM ANY LIABILITY IF THE
USER DOES NOT FOLLOW THE INSTRUCTIONS FOR USE.
Hazards
The following stickers have been affixed to the printer to warn users about the hazardous areas of the machine,
and actions which are not recommended as they will stop the machine from working properly.
Supervise the printer while it is printing to make sure it is working properly.
This device is not a toy. It should not be used by minors under 16 without the supervision of an adult.
The spatula can be a dangerous tool that may cause injuries. Use it only to remove plastic residue after calibration
assistant or a printing job.
Handle the glass printing surface with care. Make sure it is not dropped or hit with anything as this could seriously

User Manual 13
Safety and compliance
Do not touch the hot parts (heated bed and hot-ends) when the machine is switched on, and wait
15 minutes after it has been switched off before touching them.
Take care about the indications of temperature shown on the screen.
There is a potential risk of burns: the hotend can reach temperatures up to 300 °C, while the
silicone heater mat can reach temperatures of 200 °C. Do not touch either of these parts with your
bare hands.
Do not put any object or part of the body between the mobile parts of the printer, when it is moving
or can start moving.
Specifically the force of the build plate is enough to cause damage.
The printing materials are not innocuous and emit toxic fumes.
Always print in open or well-ventilated spaces and use a protective mask.
Do not breathe closer than 25 cm from the tool head when printing.
The printer is powered by mains voltage, which is hazardous when touched.
This has been marked with a high-voltage symbol on the bottom cover.
As with any other appliance, do not touch the terminals of the mains, the switch, or the power
supply. There is a risk of electrocution.
Connect the machine to an electrical outlet according to the current legislation.
Do not connect or disconnect any device and/or electrical connector when the machine is connected
to the power supply.
In the event of an emergency, stop the machine immediately by pressing the switch, and disconnect
the power supply.

User Manual 14
Proper area to install the printer
In order to ensure easy access to the printer during normal operations and maintenance, install the machine in a
place with enough space between walls and other equipment.
The distance measured from the back of the printer to the wall has to be at least 200mm to allow easy access from
the side of the printer. This space is important to guarantee easy access to extruders, FRS and external spools.
Do not cover the printer while working in order to ensure a good ventilation. Do leave at least 100mm of free space
on each side of the printer for proper ventilation and at least 200mm at the front of the printer to prevent possible
damages.
Install the printer on a table or workbench that supports at least 50kg (recommended 100kg) and that has at least
a 20% more surface than the footprint of the printer in each direction (recommended 1000mm x 800mm).
Use the machine at temperatures of 15 °C ~ 30 °C and relative humidity below 50%.

User Manual 15
Moving the machine
To ensure safe movement of the machine, follow the steps described below:
• Switch off the printer
• Disconnect the power supply cable from the rear of the machine. Also disconnect the ethernet cable and USB
Wifi dongle if it is connected.
• Ensure the glass printing surface is well fixed with the clamps.
• The printer is heavy, two people are necessary to perform this step. Make sure that the table where the printer is
being installed, is close enough.
• Lean the printer backwards holding it from both the side handle and the front-bottom.
