The film intermediate layer is made of a heat conduction plastics material, and the heat conduction plastics material contains a conductive additive An upper surface of the film intermediate layer is bound together with a lower surface of the film upper layer, and a lower surface of the film intermediate layer is bound together with an upper surface of the film lower layer.

A method for manufacturing a three-dimensional object layer by layer by applying and selectively solidifying a constituent material in powder form layer by layer by supply of energy has the steps: applying a layer (32+33) of the powdery constituent material (11) having a pre-determined height (h) onto a support (6) or a previously at least selectively solidified layer of the constituent material, and supplying energy (14) from an energy source (13) into the applied layer at positions corresponding to the cross sectional area of the object to be manufactured for selectively solidifying the constituent material. The step of applying the layer having the pre-determined height (h) is subdivided into a step of applying a first partial powder layer (32) having a first height (h1) which is smaller than the pre-determined height (h), and a step of at least applying a second partial powder layer (33) having a second height (h2) which is smaller than the pre-determined height (h), wherein the total height. (h1+112+ etc.) of the applied partial powder layers (32, 33, etc.) corresponds to the pre-determined height (h), and between the step of applying the first partial powder layer and the step of applying the second and possibly further partial powder layers, the powder layer applied last is heated.

The invention concerns a halogen-free polymeric blend capable of ionic conductivity comprising either one or more polyether-based polymers or copolymers that have favorable structures to facilitate polymer chain segmental motion and ion hopping environment, selected from the group of polyether-block-polymers and polyether-based polyurethanes, or said polyether based polymers or copolymers together with one or more ionomers formed by neutralization of ethylene acid co-polymers, as well as one or more specific halogen-free ionic complexes or salts comprising a weakly coordinating anion and a cation of an alkali metal or alkaline earth metal. Further, the invention concerns the use of said blend and a plastic material containing said blend as an additive.
