Apportation is what you're looking for... Unfortunately, there is a big lack of hard data or proof -- most accounts are similar to urban legends or ouija board stories that get passed down from person to person... I don't think I've ever heard of an out of body traveler doing it on his own...

Assuming that it is real, it seems to require a combination of a living human channel and a dead human ghost along with ungodly amounts of energy provided by other sitters in the room, first to manifest ectoplasm, and then to "cure" this ectoplasm into a tangible object. Even then, the objects are usually very small or very simple and sometimes lack detail...
