Method and device for producing a three-dimensional object

Abstract

The invention relates to a method and a device (1) for the additive manufacturing of a three-dimensional object (2) from a high-temperature polymer material. The method comprises the steps of plasticating a high-temperature polymer material above the melting temperature (TS) of the high-temperature polymer material, and cooling the plasticated high-temperature plastic to a processing temperature (TV) which lies above a crystallization temperature (TK) of the high-temperature plastic and which lies below a permissible temperature maximum value (TL) of the critical device components within a device (1) for the additive manufacturing of the three-dimensional object (2) from the high-temperature polymer material or below the melting temperature (TS) of the high-temperature polymer material. This is followed by the additive manufacturing of the three-dimensional object (2) from the plasticated high-temperature polymer material cooled to the processing temperature. The device (1) is designed to carry out the method and, for this purpose, comprises means (3) for plasticating the high-temperature polymer material, means (4) for cooling the plasticated high-temperature polymer material and means (10) for conveying the melt of the high-temperature polymer material which has been cooled to the processing temperature (TV) into means (5) for the additive manufacturing of the three-dimensional object (2).
