Bresser T-Rex Instruction Manual page 49

Raft: Enable or disable a Raft, which is several layers of material on the build
plate to help with model adhesion.
Wall: Check the Wall box to help clear leaking filament from a second extruder
during dual colour printing.
Brim: Check the Brim box to print a ring of filament around the model to help
prevent warping and assist with bed adhesion.
Resolution: For ABS and PLA printing, you can choose Low, Standard, or High
resolution.
For PLA printing, you can also choose Hyper. The higher the resolution, the
smoother the model surface, but at a corresponding cost in print speed.
More Options: Click the More Options button to reveal tabs with additional
options.
Layer: Click the Layer tab to reveal the layer options.
 Layer Height: Sets the thickness of each layer. The thinner the layer, the
smoother the model surface, but at a corresponding cost in print speed.
 First Layer Height: Sets the thickness of the first layer of the model, which
affects how well the model adheres to the build plate. The maximum
thickness is 0.4mm and the default value is usually sufficient.
Shell: Click the Shell tab to reveal the shell options.
 Perimeter Shells: Sets the number of perimeter shells. The maximum value is
10.
 Top Solid Layers: Sets the number of solid layers at the top of the model. The
maximum value is 30 and the minimum is 1.
 Bottom Solid Layers: Sets the number of solid layers at the bottom of the
model. The maximum value is 30 and the minimum is 1.
Infill: Click the Infill tab to reveal the infill options. Infill is the structure that is
printed inside the model. Infill directly affects the strength of the printed mode.
 Fill Density: Sets the fill density in 5% increments. A 100% density results in a
solid model, while a 0% density results in no infill.
 Fill Pattern: Allows you to select the shape of the infill structure. You can
select Line, Hexagon, or Triangle.
