That’s what this guide will help you find out - we haven’t just listed a group of 3D printer slicers we thought were good, but created a list of slicers which are the best in each area – for example the best free 3D slicer, or best 3D slicer for education in schools.Ī 3D slicer is a 3D printer software program that you can import models into - for example in. What Should You Look for in a Good 3D Slicer? For resin 3D printing, check out our guide to the best resin 3D slicers Best 3D Printer Slicers for Effective 3D Printing Name Note: this article focuses on 3D slicers for FDM printing. So let’s work out which 3D slicer is best for you. There's a wide collection of slicer applications, some of them free and open-source.In this guide I’ll be comparing the best 3D slicers I’ve used over all the important factors – functionality, ease of use, device compatibility, and many more crucial hidden details. Usual types of these base structures are a skirt (a single band around the base of the object without touching it), a brim (several lines of filament around the base of the object, touching it but not under it, and radiating outwards) and rafts (several layers of material that form a detachable base, with the object printed over it). The slicer can automatically add some detachable structures to minimize these problems. Rafts, skirts and brims: printing of the first object layer, the one in contact with the printer bed, has some peculiarities, like problems of object adherence to the bed, rugosity, smooth deposition of the first amounts of filament.The support touches the object in a way that is easily detachable from it at the finish stage of the object production.Ĭomparative of base layers (in blue): a) skirt b) brim c) raft, generated by Cura software 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.Nearly all slicers have some additional features, like: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.Īdditional features of the slicer The 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. In particular, the conversion from a model in STL format to printer commands in g-code format in fused filament fabrication and other similar processes. A slicer is toolpath generation software used in the majority of 3D printing processes for the conversion of a 3D object model to specific instructions for the printer.
