    Slic3r in Depth Intro Overview Slic3r is a tool which translates digital 3D models into instructions that are understood by a 3D printer. It slices the model into horizontal layers and generates suitable paths to fill them. Slic3r is already bundled with the many of the most well-known host software packages: Pronterface, Repetier-Host, ReplicatorG, and can be used as a standalone program.

    The gcode produced by Slic3r is tailored to particular types of firmware. The first step prompts for the firmware that the printer uses. This should have been specified when the printer was built or configured. The TAZ printer uses the RepRap (Marlin/Sprinter) gcode type.

  • Page 43: Configuration Wizard: Bed Size

    3.3. FIRST SLICE 2. Bed Size This setting defines the maximum distance the extruder may travel along the X and Y axis. If the dimensions are not readily available for the printer then it can be easily measured. Be sure to measure from the lower left corner where the extruder nozzle rests when in the home position to the maximum distance the nozzle can travel in each direction.

  • Page 44: Configuration Wizard: Nozzle Diameter

    Slic3r in Depth 3. Nozzle Diameter The diameter of the hot-end nozzle is usually clearly displayed either in the description of the hot-end, or in the associated documentation, when the hot-end is purchased. Common values are 0.5mm and 0.35mm. If the nozzle was home-made, or came from a source without a diameter given, then carefully measure the aperture as accurately as possible.

  • Page 45: Configuration Wizard: Filament Diameter

    3.3. FIRST SLICE 4. Filament Diameter For Slic3r to produce accurate results it must know as accurately as possible how much material is pushed through the extruder. Therefore it is vital to give it as precise a value as possible for the filament diameter. Although the filament used in FDM printers is sold as being either 3mm or 1.75mm this is only a general guide.

  • Page 46: Configuration Wizard: Extrusion Temperature

    Slic3r in Depth 5. Extrusion Temperature The extrusion temperature will depend on the material, and most can operate over a range of temperatures. The supplier should provide guidance as to which temperatures are suitable. A very general rule of thumb is that PLA lies between 160 C and 230 C, and ABS lies between 215 C and 250 C.

  • Page 47: Configuration Wizard: Bed Temperature

    3.3. FIRST SLICE 6. Bed Temperature If the printer has a heated bed then this parameter may be set. As with the extruder temperature, the value will depend on the material used. A rule of thumb is that PLA requires 60 C and ABS requires 85 C. Note: One may choose to control the bed temperature manually from the printer controller.

    Slic3r in Depth At this stage the wizard is complete and the basic configuration is defined. Figure 3.8: Configuration Wizard: End The Important First Layer Before delving into producing the first print it is worthwhile taking a little detour to talk about the importance of getting the first layer right. As many have found through trial and error, if the first layer is not the best it can be then it can lead to complete failure, parts detaching, and warping.
  • Page 49 3.3. FIRST SLICE Lower speeds. Slowing down the extruder for the first layer reduces the forces applied to the molten material as it emerges, reducing the chances of it being stretched too much and not adhering correctly. 30% or 50% of the normal speed is recommended.
  • Page 50 Slic3r in Depth ABS usually needs more cajoling and, whilst it can print well on PET and Kapton, there are reports that people have success by applying hairspray to the bed before printing. Others have reported that an ABS slurry (made from dissolving some ABS in Acetone) thinly applied can also help keep the print attached.

The Bed size setting is taken from the wizard (see p.43) and is only used for previewing the model in the plater. The Print center is the point around which the print will be centered. A Bed size of 200mmx200mm and a Print center of 100mmx100mm would sit the print in the middle.
  • Page 58 Slic3r in Depth Z offset can be used to compensate for an incorrectly calibrated Z end-stop. If the nozzle stops slightly too far from the bed, then adding a negative value will offset all layers by that amount. The correct solution however is to fix the end-stop itself.

    Slic3r in Depth Only retract when crossing perimeters - Retracting, to prevent ooze, is unnecessary if the extruder remains within the boundaries of the model. Care should be taken if the print material oozes excessively, as not retracting may result in enough material loss to affect the quality of the subsequent extrusion.
  • Page 75 3.4. EXPERT MODE extruders may need up to 4 or 5mm due to the hysteresis introduced by the tube. Lift Z - Raises the entire extruder on the Z axis by that many millimeters during each travel. This can be useful to ensure the nozzle will not catch on any already laid filament, however it is usually not necessary and will slow the print speed.

  • Page 76: Skirt Settings

    Slic3r in Depth Avoid crossing perimeters (Layers and perimeters - Advanced) - Will force the nozzle to follow perimeters as much as possible to minimise the number of times it must cross them when moving around, and between, islands. This has a negative impact on both G-code generation and print times.

    3.4. EXPERT MODE Minimum extrusion length - Dictates a minimum number of mil- limeters that the skirt should be, should the loop around the object not be enough. Cooling Temperature plays a key part in determining print quality. Too hot and the material deforms, too cool and layer adhesion may be problematic.
