Embodiment Construction

[0037] exist Figure 1a with 1b The system 1 shown in the figure comprises a system or machine frame 2 defining an interior space 3 within which a dispensing head 4 is movably supported. The dispensing head 4 comprises a nozzle 5 protruding from a rectangular surface 7 of a body 7 of the dispensing head. Inside the body 7, heating means (not shown) are provided for heating the thermoplastic material 8 above the glass transition temperature. The material 8 is supplied to the dispensing head 4 in the form of a wire, which is wound onto and fed from a reel 9 fixed to the frame 2 . After heating above the glass transition temperature, the material 8 is extruded or dispensed from the nozzle 5 in a dispensing direction defined by the central axis of the nozzle 5 or the nozzle opening of the nozzle 5 .

[0038] The distribution head 4 is mounted to the distribution head mounting structure. More specifically, via its body 7 the dispensing head 4 is mounted to an endless belt 10 whi...

Abstract

Method of manufacturing a three-dimensional object (22) by means of additive manufacturing as well as to a corresponding system for carrying out the method and a dispensing head for use in the method. The three-dimensional object (22) comprises a three-dimensional component (21). The method comprises providing a substrate (20, 20"), and successively forming on the substrate (20, 20") a plurality of layers (23, 23'), wherein each layer is formed in a pattern corresponding to a three-dimensional component (21) being manufactured and wherein each layer (23, 23') is formed by dispensing a curable material from a nozzle (5, 5') of a dispensing head (4, 4', 4") and subsequently curing the curable material (8). The three-dimensional object (22) is constituted by the combination of the substrate (20, 20") and the three-dimensional component (21), wherein the substrate (20, 20") has a non-planar surface portion and the three-dimensional component (21) is formed at least in part on the non-planar surface portion in such a manner that it is fixedly secured to the substrate (20, 20"). During forming of at least one of the layers (23, 23') and / or between forming of at least two adjacent ones of the layers (23, 23') a relative movement between the substrate (20, 20") and the dispensing head (4, 4', 4'') is effected such that in a substrate coordinate system the dispensing head (4, 4', 4") moves along a non-linear path over the non-planar surface portion.

Description

technical field [0001] The invention relates to a method for producing a three-dimensional object using additive manufacturing, wherein the three-dimensional object comprises three-dimensional components, and also to a corresponding system for producing a three-dimensional object by additive manufacturing and a system for such The distribution header of the system. Background technique [0002] Additive manufacturing or additive layer manufacturing is increasingly used for the rapid manufacture of prototypes or even final components and is subsequently also referred to as rapid prototyping and rapid manufacturing, respectively. In contrast to conventional manufacturing methods that involve removing material from blocks of material by, for example, cutting, drilling or other machining processes, additive manufacturing builds the desired three-dimensional object layer by layer directly from its digital representation. It is also called 3D printing. [0003] One type of addit...
