  • Page 63 2.3. FIRST PRINT ™ If you are just beginning with 3D printing or Slic3r, LulzBot recom- mends starting with our pre-set Slic3r profiles. You can find the TAZ Slic3r profiles at https://www.lulzbot.com/Slic3r. For information on loading and export Slic3r profiles please see page 115. Note that the pre-set profiles will only work correctly when Slic3r is in Expert mode.

  • Page 64: Configuration Wizard: Welcome Screen

    Slic3r Configuration Wizard Slic3r has two features to aid newcomers: the configuration wizard, and simple mode. Sometimes it is nice to have a helping hand when starting out with new software. The configuration wizard asks a series of questions and creates a new configuration for Slic3r.

  • Page 66: Configuration Wizard: Bed Size

    Slic3r 2. Bed Size This setting defines the maximum distance the extruder may travel along the X and Y axis. The dimensions for the TAZ print surface are X: 298 and Y: 275. Be sure to measure from the lower left corner where the extruder nozzle rests when are the home position to the maximum distance the nozzle can travel in each direction.

  • Page 67: Configuration Wizard: Nozzle Diameter

    2.3. FIRST PRINT 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. The nozzle sizes available for the TAZ hot end are 0.35mm and 0.50mm.

  • Page 68: Configuration Wizard: Filament Diameter

    Slic3r 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 69: Configuration Wizard: Extrusion Temperature

    2.3. FIRST PRINT 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 220°C and 240°C.

  • Page 70: Configuration Wizard: Bed Temperature

    Slic3r 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 35°C - 60°C and ABS requires 85°C. Note: One may choose to control the bed temperature manually from the printer controller.

  • Page 72: The Important First Layer

    Slic3r 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 73 2.3. FIRST PRINT Fatter extrusion width. The more material touching the bed, the better the object will adhere to it, and this can be achieved by increasing the extrusion width of the first layer, either by a percentage or a fixed amount.
  • Page 74 Slic3r Working with Models Yet another step lies between now and the first print - a model has to be obtained and then sliced. Model Formats Slic3r accepts the following file types. • STereoLithography (STL) files can come from a wide variety of sources and are now a de facto standard in 3D printing.

  • Page 75: Shapesmith Online Cad Tool

    2.3. FIRST PRINT You may wish to view the files before slicing and there are many free applications available, one of which is Meshlab - a comprehensive tool for viewing and working with 3D files. Figure 2.9: Shapesmith online CAD tool. Working with Plater Slic3r has a tool, called Plater, which allows one or more models to be loaded and arranged before being sliced.

  • Page 76: Plater

  • Page 81: An Example Of Insufficient Top Layers

    2.4. SIMPLE MODE • Print speed - Shorter layers will result in smoother prints but each print will take longer, simply because the extruder must trace the pattern more times. A later goal will be to strike a balance between layer height, the speed of the printer, and the quality of the resulting print.

  • Page 82: Creating A Vase From A Solid Model

    Slic3r Another tip to consider: Setting the top solid layer to zero, and setting the infill also to zero, will result in a hollow receptacle, ideal for turning models into vases for example. Here manipulating the settings within Slic3r can be used to generate different kinds of prints, and not only be used to control surface accuracy.

  • Page 83: An Example Of An Object Printed With Support Material

    2.4. SIMPLE MODE unnecessarily complex for most use cases, and so most of the time the infill pattern is either rectilinear, line, or honeycomb. Honeycomb gives the most strength but is slower than both rectilinear or line. Support material.

    Slic3r Placeholders can be inserted in the G-code commands . For example [next_extruder] would return the index of the next extruder. The RepRap wiki is a good resource to learn about the variety of G- codes available: http://reprap.org/wiki/G-code. Note: Be sure to check that a given G-code is valid for your firmware. The codes specified in Start G-code are inserted at the beginning of the output file, directly after the temperature control commands for extruder and bed.

  • Page 89: Expert Mode Speed Options

    2.5. EXPERT MODE speed is a safe starting point, and it is not unrealistic to attain speeds of up to 250mm/s (if your printer can handle it). Adjusting the speed of perimeters, infill is available in simple mode, and the general rule is to have the perimeter go a little slower than the infill in order to reduce possible blemishes on the surface (infill can be faster because slight gaps will not matter as much).
  • Page 90 Slic3r Where indicated a value can be given in percentage. This is in relation to the preceding value, e.g. 50% solid infill would be half of the value defined for infill. A few general guidelines for each option: • Perimeters - In expert mode this parameter can be increased slightly as the External perimeters option can be used to ensure blemish free external faces.
  • Page 91 2.5. EXPERT MODE • First layer speed - As mentioned in subsection 2.3, the first layer is important to lay down correctly, and a slower pace helps enormously. Setting a value of 50%, or even less, can really help. Acceleration control is an advanced setting allowing acceleration settings for perimeters, infill, bridge, as well as a default setting, to be made.

  • Page 92: Infill Pattern Settings

    Slic3r Infill Patterns and Density There are several considerations when choosing an infill pattern: object strength, time and material, personal preference. It can be inferred that a more complex pattern will require more moves, and hence take more time and material. Figure 2.22: Infill pattern settings.

    Slic3r Infill Optimization Slic3r contains several advanced infill settings which can help produce better extrusions. Figure 2.32: Infill advanced settings. • Infill every n layers - Will produce sparse vertical infill by skipping a set number of layers. This can be used to speed up print times where the missing infill is acceptable.

  • Page 97: Retraction Settings

    2.5. EXPERT MODE parts being unnecessarily solid. Adjust this option to balance these needs. • 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 98 Slic3r • Length - The number of millimeters to retract. Note that the measurement is taken from the raw filament entering the extruder. A value of between 1 and 2mm is usually recommended. Bowden extruders may need up to 4 or 5mm due to the hysteresis introduced by the tube.

  • Page 99: Skirt Settings

    2.5. EXPERT MODE • Only retract when crossing perimeters (Infill) - Tells Slic3r to only retract if the nozzle will cross the threshold of the current island being extruded. Slight ooze within the walls of a part are not seen and can usually be accepted.
  • Page 100 Slic3r • Distance from object - The millimeters between the object and the skirt. The default of 6mm is usually sufficient. • Skirt height - The number of layers to lay down a skirt for. For ensuring the material is flowing smoothly, one layer is sufficient, however the skirt function can also be used to build walls around the object in case it should be protected from drafts.

  • Page 101: Cooling Strategy

    2.5. EXPERT MODE Figure 2.35: Cooling strategy. Figure 2.35 shows the strategy adopted by Slic3r. Reading from right to left, when the minimum fan threshold (#2) is reached the fan is turned on. This increases in intensity as the layer time decreases. The print speed remains constant until the estimated print time drops below a certain threshold (#1), this is when the print speed is reduced until it reaches it’s minimum value.

  • Page 102: Cooling Advanced Settings

    Slic3r A duct may help in guiding the flow correctly, and there are several designs available online, for a wide variety of printers. Slowing Down Slic3r can tell the printer to slow down if the estimated layer time is above a certain threshold.

  • Page 103: Support Material

    2.5. EXPERT MODE • Fan speed - Determines the minimum and maximum speeds - useful for fans that run too fast by default. • Bridges fan speed - As the material stretches over wide gaps, it makes sense to try and cool it as much as possible, therefore a full fan speed is recommended.

    2.8. ADVANCED TOPICS Understanding extrusion width Two main questions affect Slic3r’s work: • How distant should extrusion paths be positioned in order to get a good continuous finish? • How much material must be extruded along such paths? If two adjacent paths are too close (or too much material is extruded), they’ll overlap.

  • Page 130: Bridging Filament Shape

    Slic3r Figure 2.65: Bridging filament shape. If you reduce the material flow you’ll get smaller circles to some extent, until the plastic viscosity decides it’s time to break your bridge because of too much tension. If, on the contrary, you extrude too much material, the shape of the extruded filament won’t change (still equal to nozzle diameter) but you’ll get a loose bridge.

  • Page 131: Extrusion Shape

    2.8. ADVANCED TOPICS Figure 2.66: Extrusion shape. When target extrusion width is thinner than layer height the shape is unpredictable so we just use the same rectangular formula but discourage usage of such thin extrusion values.

  • Page 135: Variable Filament Diameter Changing Layer Stacking

    2.9. TROUBLESHOOTING Z wobble Even if the dimensional accuracy of a single layer was correct, several stacked layers might make the hole smaller if they’re not exactly aligned. Z wobble caused by mechanical issues will reduce hole size to the internal envelope of the stacked layers: Figure 2.69: Z wobble changing layer stacking.
  • Page 136 Slic3r Backlash Backlash is a mechanical defect of one or more axes that basically reduces the amount of actual motion whenever a motor inverts its spinning direction. It’s generally caused by loose belts. On printers with a moving bed, its axis (usually Y) is more subject to backlash because of inertia.
  • Page 137 2.9. TROUBLESHOOTING however one point of particular interest for users of Slic3r is the wobble caused by motor steps not matching the pitch of the Z rods thread. This can be addressed by ensuring the Layer Height setting is a multiple of the full step length.
