To correctly wet sand a PLA 3D print, it is recommended to Provide for a smoother and shinier exterior. Ideally, any protruding edges or lengths should be sanded awayīy using a coarse sand-paper (grit size between 100 to 400). PLA 3D prints are remarkably easy to sand for getting a The remaining parts of the support structure sticking out of the Once all the support structure has been removed by handĪnd/or pliers. Good auto-body filler for plastics like JB weld plasticweld. If the holes are larger, then it is best to use a
AlternativelyĮpoxy resin can also be used. Small holes, clear nail polish topcoat/varnish works best with PLA. The main build of the 3D print, these can be filled various techniques. If, despite care, some gaps or holes have become apparent in Support material on the 3D printed object at this stage. See our post on, every 3D printing tool you will ever need – from beginner to pro.Ĭare should be taken not to remove or cut the support As such, they can be easily removed from the 3D print by either carefully pulling them off by hand, or for harder-to-remove supports, by use of needle-nose pliers and dental picks or tweezers. Photo by Rafolio Removal of breakaway support structuresīreakaway support structures are 3D printed to have lower density than the main build by having a lower in-fill percentage as well as having thinner perimeters and/or walls. HIPS (High impact polystyrene) can be used, however its higher printing temperature as compared to PLA, makes it a very difficult material to use with PLA. For PLA, both PVA (Polyvinyl Alcohol) and Hydrofill can be used as soluble support structures. Soluble structuresare made from special filaments that can be dissolved in a chemical bath post-printing, to leave the main build perfectly intact. PETG is a good choice for a double-extrusion based Breakaway SuchĪ mix of materials is possible only when using a double (or higher) extrusionģD printer. Similar strength that does not adhere too profusely to the main material. In our particular instance, PLA, or from a material of These structures can be made from the same material as the The removal process differs depending upon whether the support structure is a Breakaway type structure or made from a soluble filament. Support structures can be “Breakaway” support structures, or they can be “soluble” support structures.
