# Print Settings

Transform

Option	Description	Example	Default
Scale	Decides whether Slic3r will scale up/down the model	1.2 will scale the object to 120% of the original size	1 (100%)
Rotate	Rotates the model around the Z (vertical) axis	180 will turn the object 180 degrees (turn it around)	0
Copies along X	Creates additional copies along X axis	Using "3" will produce 3 copies of the object on the X axis	1
Copies along Y	Creates additional copies along Y axis	Using "3" will produce 3 copies of the object on the Y axis	1
Distance between copies	How much space (in mm) will be between copies	Using "20" will space the objects 20mm apart (from the edge of each object)	6

## Accuracy

Option	Description	Example	Default
Layer height (mm)	Defines the height of every layer	An object that is 5mm high and printed at 0.5mm layer height will be printed in 10 layers. With every layer 0.5mm high	0.4 (mm)
First Layer Height Ratio	This defines the ratio (percentage) at wich the first layer will be printed	A ratio of 0.75 with layer height set at 0.4mm would mean a first layer printed at 0.3mm	1 (100%)
Infill Every N Layers			1

Option	Description	Example	Default
Loops	Defines the number of loops to print surrounding the object to print	2 loops would mean that before printing the object, the printer will print 2 complete loops around the object to be printed	1
Distance From Object (mm)	The amount of distance between the loops and the object that will be printed	10 would mean that the loops will be printed 10mm (1cm) away from the object	6 (mm)
Skirt Height (Layers)	The amount of layers that the skirt will be printed for	5 would mean the the skirt is printed for the first 5 layers of the object	1

Option	Description	Example	Default
Perimeters	The number of outlines on an object for every layer	2 will draw 2 solid outlines around the edge of the object	3
Solid Layers	The amount of layers that will be completely filled (top and bottom of object)	5 will produce 5 solid layers on the top and 5 layers on the bottom of the object	3
Fill Density	Is the amount of infill to be used when filling the internal space in your object	0.5 will fill 50% off the layer with plastic	0.4 (40%)
Fill angle (°)	The angle at which the infill will be put on the layers	45 degrees will start to draw the infill at a 45 degree angle between Y and X axis	45°
Fill Pattern	The algorithm used to calculate the infill pattern		rectilinear
Solid Fill Pattern			rectilinear

Option	Description	Example	Default
Length (mm)	The amount of filament to be retracted before repositioning	1 will retract 1mm of filament every time the extruder travels	1 (mm)
Lift Z (mm)	The distance the Z-axis will move up before it moves to a new point of extrusion	5 will move the Z-axis up 5mm every time the extruder moves to a new point of extrusion	0 (mm)
Speed (mm/s)	The speed at which the Z-axis moves up and down	30 will move the Z-axis up and down at 30mm per second	30 (mm/s)
Extra Length On Restart			0
Minimum Travel After Retraction (mm)	The minimum amount for the extruder to travel before it reverses filament	2 means that the extruder will only revers filament after repositioning further then 2mm	2 (mm)

# Printer and Filament

Option	Description	Example	Default
Nozzle Diameter	The diameter of the nozzle you use	0.5 means that your nozzle has a 0.5mm hole in it where the plastic it extruded from	0.5 (mm)
Printer Center	The center of the X-axis and Y-axis	X: 100 and Y: 100 means that the center of your printbed is located at 100mm in the X-direction and 100mm in the Y-direction	X: 100, Y:100 (mm)
Use Relative E Distances			Unchecked
Extrusion Axis	The name of the axis (motor) that is used to extrude from	E means that the axis you use to extrude from is defined as the letter "E"	E
Z Offset			0

Option	Description	Example	Default
Diameter (mm)	The diameter of the filament used (generally 1.75 or 3mm)	3 means that your filament has a diameter of 3mm	3 (mm)
Extrusion Multiplier	You can use this to compensate for the diameter of the filament	1.2 would mean that your filament diameter is 120% of the "Filament Diameter" option (3mm x 1.2 = 3.6mm)	1 (100%)
Temperature (°C)	The hot-end temperature to print with (generally 185°C for PLA and 230°C for ABS)	200 would mean that your hotend will be heated to 200°C before and during printing	200 (°C)

Option	Description	Example	Default
Perimeters (mm/s)	The speed at which the outer shell of the object will be printed at	30 means that outlines of an object will be printed at 30mm per second	30 (mm/s)
Small Perimeters (mm/s)	The speed at which the perimeters of inner gaps or holes will be printed at	30 means that inner perimeters will be printed at 30mm per second	30 (mm/s)
Infill (mm/s)	The speed for filling objects	60 means that infill will be printed at 60mm per second	60 (mm/s)
Solid Infill (mm/s)	The speed for filling layers that are completely solid, like the first and last few layers of a print	60 means that solid infill will be printed at 60mm per second	60 (mm/s)
Bridges (mm/s)	The speed for printing bridges (sectors in a print that are not directly printed on underlaying layers	60 means that bridges will be printed at 60mm per second	60 (mm/s)
