Support Alert: The recommended slicing engine and printer host for the LulzBot Mini 3D printer is Cura LulzBot Edition. The Slic3r configurations (configs) on this page were developed during testing, may not be up-to-date, and are not fully supported at this time.
To get printing , the default Slic3r configurations (configs) listed below can be imported into Slic3r for ready to print settings. To download and save the configuration file, right click and select Save As.
Alternatively, to download a .zip file of all of the available slicing profiles and configs, visit our Github repository.
After downloading, import the Slic3r configuration file by selecting, in Slic3r, File > Import Config and navigate and select your pre-set Slic3r configuration file of choice.

A special note on Carbon Fiber Filament:



A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. Therefore we  recommend to use nozzle’s from Stainless steel or hardened copper alloys.

While it's tempting to try using filament containing carbon fiber, many users are reporting trouble extruding after using that material, even from different vendors. We've seen people that wear out the inside of their nozzle, not to mention having lingering extrusion issues after switching to more common filament types. One of the benefits of carbon fiber containing materials are it's strength, similarly to good quality plywood. The interlocking long carbon fiber strands give the material a super-strong core. All the filaments we've seen so far however, don't have that same kind of long carbon fiber strands, so your prints are similar to Oriented Strand Board (cheaper plywood with smaller fiber length), which isn't as strong or as durable. That somewhat defeats the purpose of using carbon fiber materials. We find that for applications needing high-strength printed parts Nylon is a great material. While a bit slower to print, the parts are much, much stronger. Keep in mind, that when using filaments requiring higher extrusion temperatures you will want to make sure to update the start/end gcode of that material. If your LulzBot Mini doesn't know to get hotter than the normal profiles it can interrupt the bed-leveling process and can cause damage to the bed, hot end or even other items.


Some thoughts on nozzle wear and 3D printing with metallic blends:


While our internal testing with the LulzBot Hexagon Hot End has not encountered measurable wear, pay attention for any print quality changes.


Advanced Tips


Speed: In general, the slower at which you print, the finer your surface finishes will appear.

Support: Support material can be printed with the same extruder and filament. It can be easily removed and set to be automatically generated or turned off completely. Generally, you can print without support material provided that any overhanging sections are less than 45 degrees.

Layer Height: The layer height determines how visible each layer is in the resulting model. The larger the layer height, the faster the print. Larger layer heights are more forgiving, while finer layer heights will take longer and need to have the various hardware and software settings balanced. However, finer layer heights will provide a smoother surface.
