1. A method for producing a three-dimensional object by solidifying successive layers of said object within a bath of a liquid material by directing electromagnetic radiation onto said material,said method comprisinga) solidifying partial regions of said layer so as to leave narrow liquid intermediate regions between adjacent ones of said partial regions while at the same time connecting said partial regions to corresponding partial regions of a previously solidified layer so as to form multilayered cells,b) interconnecting adjacent ones of said partial regions of said layer by solidifying narrow connecting regions bridging said intermediate regions in the form of connecting webs, andc) thereafter solidifying said intermediate regions between said partial regions for completing the solidification of said object.
