If you are having adhesion issues with your 3D models, PROGLU3D is something to check out on Kickstarter. Created by ProCoPrint3D of Belgium, the reusable, non-toxic adhesive product is meant to work with PLA and all flex materials such as NinjaFlex and Flexi-PLA. An adhesive that works with ABS is also offered in the perks, along with a printbed cleaner. PROGLU3D prevents nearly all the inconveniences users currently deal with such as warping, distortion, peeling, and curving.
