What a lot of us do not see or realize is that while All of us have seen images of intricately detailed and awe-inspiring 3D One of the greatest attractions of 3D printers is theirĪbility to bring outlandishly brilliant looking 3D models into the physical 3D printing complex geometries and shapes While sanding is not necessary, it may be used as a way toīlend in the filled gaps as well as to provide a finish. Support material extrude, then these should be dealt with similar to To leaking of support material onto the main build from the hot-end of the If any gaps or holes have become apparent, a possibility due To speed up the process of dissolution, an ultrasonic chamberĪfter the support material has completely dissolved, the PLAīuild should be warmed with warm water to remove any support residue. Left in lukewarm water for these supports to dissolve away and leave the PLA They are printed with special materials designed to be dissolved away to leaveįor PLA, both PVA and Hydrofill can be used. Support structures can only be used with double extrusion 3D printer models as This is where soluble support structures come in. The very least, very impractical and time-consuming. In some cases, the required support structure becomes soĬomplex that removing the support manually would be next to impossible, or at Photo by Rafolio Removal of soluble support structures If possible, a handheld rotary machine is preferable – both for ease of use, asĪfter sanding, the 3D object can be provided an optional desired finishing by polishing, painting, or varnishing. Sanding should always be done in small circular motions, and Shape, a fine sandpaper (grit size 1000-2000) should be used for the final Once the 3D object has more or less attained the desired The main build are more prone to damage by sanding. If such damage occurs, it should be filledĪnd then sanded carefully to a smooth finish. Sizes to avoid caking of sanded PLA material on top of the print.Ĭare should be taken to not over-sand the 3D print, as this Wash the 3D print with a toothbrush and soapy water in between changing grit 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. Removal of support structures after 3D printing
