Removing the printed object
In order to remove a printed object upon completion, take the following steps:
Let the printing bed cool down
●
Carefully check if the piece can be removed easily by hand
●
If it sticks too strongly, use the included spatula to carefully loosen the object from the printing bed
●
Cleaning the printing head (extruder)
After some time the nozzle and the heating block of the Hot-End may get dirty. In order to clean it,
take the following steps:
Put the printing head into an easily reachable and comfortable position
●
Heat up the Hot-End to the temperature of the respective used material
●
Clean the nozzle and the heating block from below with the included brass brush
●
Material selection
The temperatures listed here are based on our printers and
should be treated as a recommendation only. Please tweak
them to your own needs as required.
3D printers need materials to create object from like “common” printers. Depending on the printers
technology you are able to use different types of materials.
Thermoplastic, also known as a thermosoftening plastic, is a polymer that turns to a liquid when
heated and freezes to a very glassy state when cooled sufficiently. Thermoplastic polymers differ
from thermosetting polymers (Bakelite) in that they can be remelted and remoulded. Many
thermoplastic materials are addition polymers; e.g., vinyl chain-growth polymers such as polyethylene
and polypropylene.
