However, the smaller the layer heights, the longer the printing takes. These layer heights produce a smoother surface compared to thicker layers. If the print is to be of high quality, the layer height is 0.1 millimeters or lower. Heights between 0.02 millimeters and 0.5 millimeters are very often used. The quality of the print depends on the layer height or thickness. This is what it looks like when you show all settings and search for “Raft”: You can leave most of the settings at the default values. We will only cover the most important settings for your Raft here. However, you can get the most out of your printer if you choose the right settings. The “Custom” option, on the other hand, is rather complicated – especially if you also show all the hidden options in the settings. Here, everything is clearly laid out and virtually self-explanatory, which should suffice for the first print. Beginners in 3D printing should go with the “recommended” option. Cura distinguishes between the option “Recommended” and the option “Custom”. Below the material selection is the selection of the print setup. Now that that’s clear, let’s get to the real issue: what are the best settings in Cura for a good print result when working with the Raft? Too Many Settings?Ĭura from Ultimaker is actually quite simple in design. One way to disable the Raft is to change the plate adhesion type to Skirt. The creation of a Raft is in the “Build Plate Adhesion Type” setting in Cura. If you don’t need a Raft, I recommend at least printing a Skirt to quickly identify printing issues. In addition, a Raft needs quite a bit of material and, above all, time. And the surface of the bottom will never be 100 % smooth after removal. The disadvantages: Depending on the material and the exact shape of the component, it is difficult to remove. A Raft can give the printed part more stability: In this case, the auxiliary construction is actually the simplest solution if the component cannot be placed on its side or otherwise modified.Compensating for height differences in warped print beds: In this case, the Raft is without alternative, if you refrain from a new print bed ….A shirt consumes significantly less material than a Raft. a strip only a few layers high running around the component, is sufficient to get the material flow going evenly. It takes a moment for the material to flow evenly. Start filament flow evenly: At the beginning, there may be air in the extruder, sometimes the nozzle is clogged or filament evaporates.Sometimes it is also sufficient to clean the print bed to improve adhesion. ![]() Improve adhesion: Components with a large contact surface usually have good adhesion anyway.If these are no longer needed or are replaced by alternatives, you don’t need a Raft. I also share with you my experience on how to create a good print bed adhesion even without a raft.Ī raft improves print bed adhesion – especially for filigree first layers.įor components that have good adhesion to the print bed anyway, a Raft is a waste of material and time. In this article you will learn how to optimize the settings in Cura for rafts. ![]() ![]()
