I’ve got the 3D Props NL armour. Haven’t started printing it yet though as I have other projects queued first. ABS armour, specifically vacuum formed ABS armour, is more pliable and more forgiving its 3D printed equivalent in PLA, PETG or even ABS. I took a fall in my stormtrooper costume about a year ago. Apart from a few scratches, there wasn’t much damage. Had it been printed, the parts would at best have cracked, at worst shattered. The advantage of 3D printed armour is that one can easily resize parts to ones own unique dimensions. The strength of the parts depends on a variety of factors though, such as print material, print wall thickness, infill %, and even heat the plastic was fused at. This is in addition to how the parts are finished, e.g. spray filler/putty vs. Plastic wood filler vs. Bondo, vs. Auto car putty, vs Epoxy resin, vs UV resin. I don’t believe there’s one best medium for our hobby. One has to pick those that one is most comfortable working with.
