While the outside still requires post-processing to remove the close skirt, this saves a lot of time removing brim from the inner thin parts of the print. This allows for a brim to only be on the outside of the print. We then change the line count to 10-15, the start distance to. By default this setting is set to 100, but usually the bottom of the prints will. Upon choosing “None” for the Platform adhesion type, click on the “…” for more options. Initial Layer Flow defines how much material is extruded on the first layer. This has led us to change to a close “skirt” instead of a brim. The default Initial Layer Line Width in Cura is 100. For example, you can set the layer lines in the first layer to be half ( 50) or twice as wide (200) as the rest of the layer lines. We have had parts where the brim is far more difficult to remove cleanly than the parent support material. The Initial Layer Line Width setting prints the first layer lines as a fixed percentage of the Layer Line Width. The problem with a brim, especially on PLA, is the difficulty to remove. Our PLA settings usually have this set to off by default and we turn it on manually for these special occasions. While a brim is usually not needed on PLA prints, but larger prints can still warp and skinny parts have difficulty sticking to the bed without being knocked over. Within the same section as the support settings you will also find the platform adhesion type. Pictured Below: From Left to Right – 100 micron layer height (fine quality), 250 micron layer height (standard quality), and 380 micron layer height (draft quality) We have found this to help stick to the bed without impairing the print quality. Within the Quality area of the Advanced section we do not increase the initial layer thickness but we do increase the initial line width to 115%. We set our retraction speed to 10mm/s and our distance to 1.5mm. When clicking into the Advanced Settings tab we then take a look at the Retraction and Quality sections of Cura. 1mm so that skinny prints are less likely to be knocked off. The Z Hop when retracting is set to a small. This will help prevent “hairy” sides of a print. Minimal Extrusion Before Retracting: 0.005mmĬombing refers to the printer head following the path of the print rather than attempting to clear gaps. Upon clicking the “…” next to “Enable retraction” we have our profile as such: We then hone in the retraction settings for PLA. Our standard quality print settings are at a. 1mm layer heights will take twice as long as one at .2mm, so these factors are important to consider. The layer height of your 3D print is very dependent on the nozzle size of your 3D printer as well as the quality of the print you would like.
