Method for producing a three-dimensional object

摘要

A method serves to produce a three-dimensional object by additive construction in direct construction sequence from solidifiable material, which is either present in the starting state in a fluid phase or can be liquefied, where multiple material components are discharged alternately in a programmable manner by means of multiple discharge units and configure different parts of the object joined to one another as a result of the discharge, where the geometric proportions obtained during discharge already correspond to the object, and because the material components form between them either edge regions merging into one another without boundaries or boundary regions of the different material components abutting one another without joining, a method and an object produced therewith can be provided, in which boundary and edge regions are formed “as if from one piece” between different material components even in the case of complex geometries.

1. Method for producing a three-dimensional object in direct construction sequence by additive construction from solidifiable material, which is in the starting state a plasticized material or a plasticizable material,
wherein in the direct construction sequence different material components are discharged under a pressure of more than 10 MPa alternately in a programmable manner by means of multiple discharge units and, already joined to one another as a result of the discharge, configure different parts of the object, wherein the different material components are placed next to one another drop by drop wherein the pressure generates the drops by direct coupling, wherein the geometric proportions obtained during discharge already correspond to a geometry of the object in a final state, wherein the material components between each other form edge regions merging and fusing into one another without boundaries, wherein the material components constitute a connecting structure at the edge regions.
