![]() In the case of an object layer that is floating (by example, the flat roof of a house or an horizontally extended arm in a figure), the slicer automatically can add supports for it. As a consequence, all object parts must overlie, at least in some part, over another one. Supports: Most of the 3D printing processes create the object layer by layer, down to up, with the layer under construction being deposited over the previous one.Support structure (in blue) generated by Cura software. ![]() The amount of these structures is called infill density, this parameter being one of the adjustments to be provided to the slicer. The hollow object can be partially filled by internal structures, as internal walls, to provide additional robustness. The slicer can automatically convert solid volumes to hollow ones, saving costs and time. Infill: Solid objects need a large amount of valuable material (filament. ![]() Slicers may have additional features, such as:ĭifferent densities of infill (in yellow), as generated by Cura slicer, from solid to hollow. All these movements, together with some specific printer commands like the ones to control the extruder temperature or bed temperature, are finally written in the g-code file, that can afterwards be transferred to the printer. Features of Slicers Ī slicer first divides the object as a stack of flat layers, followed by describing these layers as linear movements of the 3D printer extruder, fixation laser or equivalent. It converts a model in STL format to printer commands in g-code format for use in fused filament fabrication and other similar processes. ![]() A slicer is toolpath generation software used in 3D printing processes to send the conversion of a 3D object model to specific instructions for the printer. ![]()
