Shell Thickness
The total width of an outside wall of a 3D-printed part. Shell thickness should be
a multiple of nozzle size. Two shells is typically best. An increased number of
shells will lead to a stronger model.

Skirt
A platform adhesion option that extrudes an offset outline of the model on the
first layer of the print. The skirt helps to remove unwanted colors and build
pressure for material extrusion. It also checks the accuracy of bed leveling.
Slice
The action of changing a model file (STL, OBJ, etc.) into a a G-code file. The
coordinate type can vary depending upon setting selection. The most common
type uses cartesian coordinates on an XYZ plane.

Slicer
Slicer
A type of program, such as Cura or Repetier Host, that allows manipulation of a
3D model and converts the file type into a coordinate system (usually .gcode) the
printer follows to create a model.

Soft Pull/Soft Removal
The process of heating filament to the phase transition temperature (solid to
liquid) and removing it from the extruder assembly. The process helps to
remove unwanted material and can assist in the removal of nozzle blockage.
NWA3D recommends to always remove filament using the soft pull method as
preventive maintenance for your 3D printer.
Stepper/Stepper Motor
An electric motor that moves in discrete movements, or steps, to allow more
precise regulation of its movement.

STL
The STL file format (STL stands for stereolithography) is the recommended file
format for 3D models for 3D printing. The filetype contains the best mesh for
solid 3D-printed objects.
