X DICTIONARY
ABS – (poly acrylonitrile butadiene styrene) – apart from PLA one of the main materials for 3D printers. Features a high impact
strength, hardness and resistance to scratching. It is not resistant to UV radiation. Soluble in acetone, which allows for post-pro-
cessing of prints by using the acetone vaporizing method. ABS prints can also be glued together with ABS solved in acetone.
ABS features a fairly significant thermal shrinkage (up to 0.7%). The typical operating temperature for ABS is 220 to 250 degrees
Celsius and about 100 degrees for the bed. The heated working space is necessary to maintain dimensional compatibility for
printed items.
Adhesion
– in the 3D print context it means the adhesion to the device bed. Insufficient print adhesion can result in partial or com -
plete tear of the print from the table during printer operation. The ceramic table of the 3DGence ONE provides a good adhesion for
the certified materials, however for hard to print plastics there is a lot of commercial solutions available for improving adhesion
of the print to the bed. Grease or soiling on the table has a negative impact on adhesion.
Autocalibration – a printer capacity to perform an automated bed calibration. This process is designed to generate curve and
irregularity maps for the working table and by introducing dynamic corrections it provides a constant height of the nozzle over
the bed. It usually takes from a few to several dozen minutes, and necessary user operations are reduced to starting the process
by using an appropriate command.
Autocompensation – consists in a single-point measurement of the distance to bed and determining a correct distance to start
a job. This process takes place each time before printing. After setting a correct height over a single point, further part of the
print will be performed by taking into account the table curve pattern stored in the printer memory – thanks to this, the distance
between the nozzle and working table is always the same and corrected in Z axis on a continuous basis.
Bridge – a part of model printed in the air, suspended between two parts of the print. It is subject to special calculations while
preparing the file for printing, If the bridge is too long, it may be subject to deformation. In such cases this component should be
supported with support structures.
Brim – one of the methods of improving print adhesion to the bed. It consists in increasing the adhesion surface to the bed by
generating additional, external brims of the solid at the level of the first layer of the print. The more brim lines will be added, the
larger will be the adhesion surface. Typically, from 5 to 20 brim lines are used. The brim should be used, in case of problems with
detaching prints from the bed.
CAD (Computer Aided Design) – collective term for various computer aided design processes. The CAD methodology is used in
mechanical, electrical, medical and architectural engineering. The base for CAD methodology is geometrical modeling aimed at
creating two or three-dimensional representation of the planned component. There are various CAD software packages availa-
ble, adjusted to users’ needs and requirements. From those programs models in STL or OBJ formats are exported for use in 3D
printing. The most popular CAD packages include: SolidWorks, Inventor, PTC Creo, CATIA, Rhino, SolidEdge – however there many
others.
Curling
– a negative phenomenon that occurs during 3D print using FFF technique. Curling can be observed while printing
overhangs or sharp edges between faces of a solid. It manifests as curling of the print edges upwards. In extreme situations it
may lead to print failure, and always have a negative impact on visual effect, especially at the bottom parts of the print. It leads
also to collisions of the printing head with the print during operation. The basis method of fighting against curling is the active
print cooling. If turning on the fans does not help, it is good to lower the speed of printing.
Slicing – the process aimed at generating paths and instructions for the printer (machine code, G code) from a 3D model. At the
level of slicer we can choose such settings as layer thickness, print speed, filling density, thickness of solid walls or nozzle and
printing bed temperature. In addition, it is also possible to select the use and the density of supports and one of the few ways of
improving the print adhesion to the bed (e.g. raft or brim). The 3DGence ONE printer uses the 3DGence Slicer program with prede-
fined settings from various materials and resolutions. The final effect of slicer operation results in obtaining a machine code re -
presenting a specific 3D model in the form of G code (g-code, *.GCODE) that is subject to interpretation by the printer electronics.
Nozzle – a head component coming into direct contact with the print. The nozzle heated to temperature specific for a material
makes it flow and forms a thread of plastic with a rated nozzle diameter. The 3DGence ONE printer as standard is equipped with
a 0.4 mm nozzle. The nozzle outlet diameter affects the available resolutions, print speed and accuracy.
