If you want to print in polycarbonate and ensure that it sticks to the print surface, Airwolf has a product for you. It will prevent warpage and bad prints.
After the great success Airwolf had with their Wolfbite ABS adhesive, now they present Wolfbite Nano adhesive solution for PLA filaments. It will help the object stick to the print surface and prevent warping and similar problems.
From the Wolfbite Nano page:
WolfBite Nano is applied with an applicator brush straight onto glass, eliminating the need for tape. One light coat of Wolfbite can be used for several prints. After applying Wolfbite Nano directly on glass, printing can commence immediately, either with a heated or room-temperature bed.
Airwolf 3D specially formulated the proprietary solution to not only promote excellent adhesion but also to make part removal easy. Parts maybe removed post print by immersing the glass plate in water for a short period of time, if necessary.
“As manufacturers of 3D printers that are capable of printing large parts in PLA, we are aware of the frustrations with painter’s tape and adhesion,” said Wolf “After months of research and development, we are pleased to offer a solution that will benefit nearly all desktop 3D printer users. Wolfbite NANO™ was developed at Airwolf 3D through collaboration with Professor Miodrag “Mickey” Micic, Ph.D., who is a department chairman at Cerritos College in Norwalk, Calif., and a well known polymer chemist.
“This is a new, environmentally friendly solution for resolving the acute problem of PLA- based 3D printing, part adhesion and warpage. The solution is based on a combination of green chemistry and nanotechnology to create the best possible adhesion using compounds which are generally regarded as safe,” said Micic.
Wolfbite is packaged in a two fluid ounce container and comes with a foam brush applicator. It is currently available for sale on the Airwolf website at an introductory price of $19.99.
Airwolf is surely becoming industry leader in adhesion solutions! Good work!
The enclosure developed by repkid is a simple wooden box made from thin MDF sheets and wooden beams structure. It is insulated by double-ply cardboard glued to the inside of the box. To prevent ABS warping it is heated by simple household hair dryer.
Parts printed inside the heated enclosure on the left, and ABS part printed without heated chamber on the right with warping.

Heated chambers for 3d printing are patented by some corporation and I'm not sure what implications patent law has on projects like this one ...
Thanks to youtube user JMEMetzel's instuction video, here is an interesting way to prevent warping or bending when 3d printing large objects on your diy 3d machine. Problem happens when there is a difference in cooling of ABS plastic due to a size of a printed object. He solved it by placing holes and notches to avoid big differences in cooling of large model.
