Viesturs: Such numbers seem hard to come by for the materials typically used in DIY printers, such as PLA, ABS, and (at least experimentally) Nylon. I suppose one could start with the bulk properties published in typical materials handbooks (sorry, mine reverted to NIST when I retired) but evaluation of the artifacts made from specific materials is probably still necessary. As for the photo-initiated resin, there's still more choices. Here's what I was told by Michael Joyce, the b9creator guy, about his specific resin in answer to my question "would these artifacts [like the Eiffel Tower and lattice ball shown on the b9creator site] survive being handled by 'tweens"? "The tower can take some twisting (maybe 30 degrees from base to top). The spheres can be thrown against walls/floor and they just bounce. Probably not as strong as abs, but pretty good for resin." Like I said, DIY printing is all in its infancy. Some the commercial sites do offer more information but not enough, in my opinion.
