Hot end
The heated portion of the extruder mechanism, which gets hot enough to melt plastic (or potential-
ly other materials). The hot end used in the Creatr HS can withstand temperatures of up to about
270 °C.
(Heated) Print bed
A build surface that is warmed in order to keep the base of an extruded part from cooling (and
shrinking) too quickly. If the base layers of a print shrink too quickly, this will lead to so-called
'warping' : the most common result is corners of parts lifting off the build surface. Heated beds
usually yield higher quality of finished prints. You can heat the bed to a maximum of 90 degrees.
Nozzle
The nozzle is the part of the extruder where the filaments exits from: The default nozzle orifice
diameter of the Creatr HS is 0.35mm, but this part can be replaced with different sizes to create a
larger or smaller flow of filament.
Print head
The print head is the part of the printer that moves along the x- and y-axes to build up the print. The
print head contains the nozzle, extruder and the hot end.
Print Sticker
Since the print bed is made out of glass (to keep it as straight as possible) , you need to place a print
sticker on the bed before printing, to make sure your print sticks to the bed.
Retracting
Retracting means that the filament is pulled out of the extruder. It is the opposite of extruding.
Slicing
Slicing is the process through which the stl file (or the 3D model) is transferred into a gcode (print-
able file). Materialise Creatr is the slicing software that comes with your Creatr HS.
STL
STL is a file format in which you have to save your 3D model in order to be able to convert it to a
printable file. STL files describe only the surface geometry of a three dimensional object without
any representation of color, texture or other common CAD model attributes.
Support material
Due to the printing technique used, the Creatr HS has limitations in printing objects with more
than 45 degrees overhang. To overcome this problem the printer can print a support structure
which literally supports your actual print.
