Raft Top Infillĭetermines the infill density of the top layers of the raft. The exact value will need to be tuned depending on material selection and part geometry.įor compatible model and support material pairs, set this to a value between 0 and 0.1mm, depending on how well your toolheads are calibrated. If the same material is used for both raft and model, this should be a non-zero value. Separation Distanceĭetermines the gap left between the final top layer of the raft and the first layer of the model. Set this to a non-zero value between 2 and 5. Specifies how far beyond the perimeter of the model the raft should extend. Specifies the thickness of the raft base layer. Specifies the thickness of the raft top layer.Ī value of 2 is recommended when the raft is the same material as the model, 3 when using a compatible support material. When using a compatible model and support material pair, the raft should be printed with the support material loaded on T1. Specifies which extruder should be used to print the raft. The raft is composed of an extremely thick base layer followed by a top layer with regular extrusion parameters before the actual model begins to print. The raft is an optional thick base layer which serves as the foundation layer between the build surface and the part. A single outline is sufficient to prime the nozzle, while 5 or more should be used to confirm accurate bed-to-nozzle spacing. Skirt Outlinesĭetermines the size of the skirt. When this is 0, the skirt is referred to as a brim. Skirt Offset from Partĭetermines the offset between the skirt and the part. Generally set to 1.įor parts with a very small cross section or contact surface area on the first layer, you may want to increase this number up to 5 to provide a solid foundation. Skirt Layersĭetermines the height of the skirt. For dual extruder prints, set this to “All Extruders”. Set this to the same value as the Primary Extruder in the Layers tab for single extruder prints. Specifies which extruders print the skirt. If the part does not need the extra build plate adhesion from a brim, a skirt is still useful for confirming that the models are properly placed and bed-to-nozzle spacing is accurate. When there is a gap between the extension and the part, it is referred to as a skirt and its purpose is usually to prime the nozzle prior to printing the model. When this extension is directly connected to the part, it is referred to as a brim, and its purpose is usually to provide additional surface area for the part to stick to the build surface. Both the skirt and brim refer to an extension of the first layer of your print which follows the contour of the model.
