The additional extruder could print a different colour or material. Moves the nozzle whilst retracting so as to reduce the chances of a blob forming. This can be Care should be taken with the positioning of the fan so that it does not cool any heated bed more than necessary. Slic3r Support 8. Z offset can be used to compensate for an incorrectly calibrated Z end-stop. Support generation is a relatively complex topic.

Any spaces between the extrusions are adjusted accordingly. The more material touching the bed. This would cause poor flow and lead to a failed print. Bed material. First Slice Fatter extrusion width. Directly related with the above. No cooling. Setting the first layer height to 0. Many options exist for the material to use for the bed. It is therefore highly recommended to combine the high first layer height technique recommended above with this one.

Simple mode offers a reduced set of options. There are several factors that influence how high each layer should be: Print Settings The Print Settings tab provides the opportunity to change settings related to the actual print. A later goal will be to strike a balance between layer height. These may be chosen from the Preferences window found under the File menu.

Aesthetics plays a role here. Lower layer height should result in prints with less noticeable ribs or bands. Whereas the other tabs are changed rarely. Layer height is the thickness of each layer. Expert mode give more control over how Slic3r produces the G-code and will be looked at later. Simple and Expert.

Shorter layers will result in smoother prints but each print will take longer. Simple Mode: First Slice Figure 3. Perimeters defines the minimum number of vertical shells i. Unless the model requires single width walls it is generally recommended to have a minimum of two perimeters as this gives some insurance that if a section of the perimeter is not printed correctly then the second perimeter will help cover it.

For the bottom layers the important factor to consider is how the surface will look should there be a mistake whilst laying down the first layer. Another tip to consider: Setting the top solid layer to zero. Here manipulating the settings within Slic3r can be used to generate different kinds of prints. An example of insufficient top layers.

A similar consideration is required for the top layers. Choosing support material Generate The more exotic fill methods are usually too slow and unnecessarily complex for most use cases. Support material. A density value of 0. A value of 0. Creating a vase from a solid model. Honeycomb gives the most strength but is slower than both rectilinear or line.

Printing a model from the bottom up. Slic3r offers several fill patterns which will be discussed in more depth in section 4. Choosing a Fill pattern will depend on the kind of model.

Fill density is defined on a scale of between 0 and 1. Infill Choices. It is sometimes worth considering altering the orientation of the model in order to possibly reduce overhangs.

The outline of the model may benefit from being printed slightly slower so that the outside skin of the print has fewer blemishes. The raft also requires post-processing to remove it. As the infill is hidden this can be extruded a little faster.

In simple mode there are only three speed settings to consider: Raft layers will add additional layers underneath the model and stems from the early days of 3D printing. The Pattern spacing option determines how dense the support material is printed. An example of an object printed with support material. Take care though not to go too fast as higher speeds results in thinner extrusions. It can help with prints without a heated bed. The jump between the end of one extrusion and the next should usually be performed as quickly as the printer will allow in order to minimise any mess caused by material oozing from the nozzle.

Sequential printing options. An example of brim. It will also decrease the risk of a problem ruining the entire print. When printing several objects at once it can be useful to print each one separately as this will minimise oozing and strings running between the prints. Sequential printing.

Brim width is used to add more perimeters to the first layer. The brim is then cut away once the print is finished and removed from the bed. Take care if the extruder is not mounted centrally. Slic3r should warn if it detects the nozzle or extruder will collide with a part. The vertical distance between the nozzle tip and the X axis rods. The clearance that should be given around the extruder.

The clearance cylinder around an extruder. The Extruder clearance parameters help Slic3r detect potential collisions: Whilst the value should ideally be set in the firmware it can be useful to test slight changes to the rate by altering this value.

It varies the amount of plastic proportionally and should be changed in very small steps e. The Extrusion multiplier setting allows the fine tuning of the extrusion flow rate. The Diameter setting will already have been filled from the value given during the wizard see p. These values are also filled from the wizard.

Welcome to the Slic3r Manual

The Print center is the point around which the print will be centered. This can be remedied by actively retracting the filament between extrusions. A sheet of paper makes a good gauge for this very small distance. Bowden extruders may need up to 4 or 5mm due to the hysteresis introduced by the tube. Setting the Length parameter to a positive value will cause the filament to be reversed by that many millimeters before travel.

A value of between 1 and 2mm is usually recommended. G-code flavour defines the dialect of G-code generated. Setting the Lift Z parameter to a positive value will raise the entire extruder on the Z axis by that many millimeters during each travel. If the nozzle stops slightly too far from the bed. Unless the material being extruded has a very high viscosity it may ooze between extrusions due to gravity.

A Bed size of mmxmm and a Print center of mmxmm would sit the print in the middle. The optimal Z endstop position is where the nozzle tip barely touches the surface of the bed when homed. This can be First Slice Size and coordinates. The retraction will then be compensated for by the same amount after the travel move. As selected in the wizard see p. It is not recommended to use this setting to try and improve layer adhesion. The correct solution however is to fix the end-stop itself.

Z offset can be used to compensate for an incorrectly calibrated Z end-stop. The Bed size setting is taken from the wizard see p. Nozzle diameter was defined in the wizard see p.

Should it be desired to print away from the center. Some common G-codes to use before the print starts are: Sets the heated bed temperature to zero. Some common G-codes to use after the print ends are: End and Layer Chance G-codes. Homes all the axes. The codes specified in Start G-code are inserted at the beginning of the output file. Sets the extruder temperature to zero. Placeholders can be inserted in the G-code commands3.

Disables the motors. Be sure to check that a given G-code is valid for your firmware. For example [next extruder] would return the index of the next extruder.

Home the X axis. Custom G-code commands can be run before a print starts and after a print finishes.

The RepRap wiki is a good resource to learn about the variety of G-codes available: Note that if temperature control commands are specified M and M then these will replace the temperature G-codes introduced by the Filament settings. It is similar to the STL format. The files simply describe the surface geometry of a 3D object without any additional information such as colour or material.

Model Formats Slic3r accepts the following file types. Whilst the format is deemed a standard it has yet to be widely adopted in the 3D maker community. Finding Models The 3D model files may come from an online repository. In addition to describing the geometry of the 3D model it can also describe colours and materials.

Working with Plater Slic3r has a tool.

Shapesmith online CAD tool. This is useful in making sure the plastic is flowing smoothly from the nozzle when the model is starting to be printed. In the figure below. Plater Once you have acquired a model. The ring around the model is a skirt. Minimug model. STL file loaded.

Save the current set of models as a single STL file. Adjust how many copies should be printed. First Slice The model can be repositioned by dragging the representation of it on the left of the screen around the bed. The buttons along the top of the file list allow you to arrange the models. Opens a file dialog to add a model to the plater. Slic3r will attempt to fix any problems it can. On the right-hand side is the list of currently loaded files. Starts slicing the model and produces a G-Code file.

Remove one or all models from the plater. The buttons along the bottom of the file list allow you to add. Increase or decrease the size of the printed model. Note that the dimensions of the bed should match your printer.

Attempt to arrange the models to give the optimal layout. Rotate the selected model around the Z axis. Netfabb Studio: Netfabb Studio Netfabb produce a range of 3D modelling applications.

This version includes a mesh repair module which can help eliminate the various problems faced. If Netfabb detects a problem it will show a red warning sign in the bottom right-hand corner. Up-to-date instructions can be found on the Netfabb wiki If the application complains that a model cannot be sliced correctly then there are several options available. Choosing Default will cover most cases. Netfabb Cloud Service Netfabb also hosts a web service where an STL file may be uploaded for it to be checked and repaired Select execute to run the scripts.

This will open the part repair tab and show the status of the model.

Default and Simple. FreeCAD Freecad15 is a comprehensive. CAD program which comes with a mesh module. Netfabb Cloud Services. A small message in the bottom left corner will indicate if the model appears to have problems. If a corresponding problem is detected the Repair button becomes enabled. It may be the case that the script damages the file.

Slic3r - RepRap

FreeCAD part repair. Amongst the open-source solutions are: Repetier17 and Rep- snapper Now would be the time to fire up the printer and try it out. The following sections will cover the options available in expert mode. A variety of host software is available to send the G-code to the printer. Adjusting the speed of perimeters. Doing this provides several benefits. An additional benefit is that a faster travel movement. Travel speed is a safe starting point. Differen- tiation between external.

The best approach is to increment the various speed parameters in small steps and observe the effect each change has on print quality. Expert Mode 4. Expert mode offers more parameters to fine tune printer speeds.

A few general guidelines for each option: Where indicated a value can be given in percentage. Expert mode speed options.

This is in relation to the preceding value. As fast as your printer will allow in order to minimise ooze. Going too slow will result in sagging.

In expert mode this parameter can be increased slightly as the External perimeters option can be used to ensure blemish free external faces. As mentioned in section 3. As fast as you can without compromising the integrity of the fill structure. A setting of zero disables gap filling completely. Meant for holes. Allow time for the extrusion to cleanly cover the previous top layers and result in a tidy top surface.

A slightly slower value may ensure cleaner surfaces. Having the extrusion span distances depends on the material and cooling. The bottom of the model. Generally support structures are quick and dirty.

Filling in small gaps results in the extruder quickly oscillating and the resulting shaking and resonance could have a detrimental affect on the printer. A smaller value here can guard against this. Faster extrusions can break and result in weak spots.


Experimentation is the key here. Take into account any restrictions enforced by the firmware as many have settings for the maximum safe speed of each axis. Lulzbot one of the companys supporting development wrote a. The following page has links to Slic3r Tutorials, Documentation and Videos. Check out the source code over at GitHub. The actual Slic3r at time of writing V1.

It will not deliver optimal results if the parameters for standard are left at "0". To avoid the Bug, you will need to insert your actual nozzle-diameter or your desired extrusion width.
