Safety Instructions
Building the printer will require a certain amount of physical dexterity, common sense and a
thorough understanding of what you are doing. We have provided this detailed instruction to help
you assemble it easily.
However ultimately we cannot be responsible for your health and safety whilst building or
operating the printer, with that in mind be sure you are confident with what you are doing prior to
commencing with building or buying. Read the entire manual to enable you to make an informed
decision.
Building and operating involves electricity, so all necessary precautions should be taken and
adhered to, the printer runs on 12V supplied by a certified power supply, so you shouldn’t ever have
to get involved with anything over 12V but bear in mind there can still be high currents involved
and even at 12V they shouldn’t be taken lightly.
High temperatures are involved with 3D Printing, the Extrusion nozzle of the hot end can run about
230°C, the heated bed runs 110°C and the molten plastic extruded will initially be at around 200°C,
so special care and attention should be made when handling these parts of the printer during
operation.
We wouldn’t recommend leaving your printer running unattended, or at least until you are confident
to do so. We cannot be held responsible for any loss, damage, threat, hurt or other negligent result
from either building or using the printer.

Check the power input
This step is very important. If you didn’t choose the wright power input, the power supply unit will be burned out.
Check the power input of the power supply unit. You can choose either 110V or 220V according to the Power
regulation in your country.
Tear off the yellow sticky note to check it. You can use a hard stick to reach into the power box and switch it.
