It is not necessary to hollow-out a model in an attempt to save on material. When the faces are not fully closed, they produce gaps or holes in the model and those holes and gaps will keep the model from printing correctly.ĭoes it need to be hollowed out or completely filled? More technically, all faces of the object must construct one or more closed volume entities. The mesh or surface of the 3D model must be watertight and a solid. It is recommended that part thicknesses be at least 0.5 mm or greater. The minimum thickness of a layer is 0.12 mm so the smallest features that will accurately be produced must be at least this value. The 3D model must fit within the build envelope of 280 x 280 x 250 mm. Most CAD programs can save or export in this format, as can other free 3D modeling software packages, such as Sketchup, TinkerCAD and Blender. To print a model on the library's 3d printers, it must be exported as a Stereolithography file, with an STL extension (.stl). What do I need to know about creating models? They produce models from PLA filament, which is a type of thermoplastic made from plant sources. The Valley Library has a Makerbot Replicator 2, a Makerbot Replicator 2x, a Fusion3, and a Lulzbot Taz 6. What kind of printers does the library use?
