In the past, I’ve done a fair amount of 3D printing with ABS. One of the nice things about ABS is that you can use acetone to join parts together very strongly by a technique known as “solvent welding.”
Cured Formlabs resin won’t dissolve in acetone, but you can do the same sort of solvent welds between parts with just a little bit of extra clear resin and a laser pointer (or other UV source, like the Sun). If I have two pieces I want to join together, I take just a small amount of the resin, using a toothpick or the like, and spread it around where I want the join to take place. Then, I push the objects together and expose the resin to UV light to get it to cure. Blue-violet (405 nm) laser pointers are perfect for this and are inexpensive ( http://www.amazon.com/QQ-Tech/b/ref=bl_dp_s_web_3562808011?ie=UTF8&node=3562808011&field-lbr_brands_browse-bin=QQ-Tech). The resin cures very quickly, so you have a strong bond in no time.
And you can use the exact same technique to glue other things around the house! Just a small amount of resin can be a surprisingly effective UV-cured glue on lots of surfaces.
