Problems solved by technology

However, this is time consuming and also requires a lot of human work resources
[0006] When one or more subsequent operation steps are to be used, such as forming (machining), grinding and polishing, the additively manufactured object is mounted and adjusted in processing equipment such as CNC (Computer Numerically Controlled) machines so that it can be provided in Accuracy of desired shape within certain dimensional tolerances, which can be difficult and time consuming
In machining operations, it may also be difficult to guarantee repeatability in terms of dimensional tolerances and accuracy between several AM objects

Abstract

The present invention relates to a method for producing an object (108) of metal wherein the object (108) is built with an additive manufacturing process on a base device (101) having a build surface(104) at one end, said base device (101) being part of a base device system (100) comprising at least one base device (101) and a supporting means (102) holding the base device (101) in a fixed position during the additive manufacturing process, wherein the method comprises the steps of: building the object (108) on at least a part of the base device build surface (104) with the additive manufacturing process, removing the base device (101) from the supporting means (102), connecting the base device (101) to a CNC machine provided with at least one machining tool and, separating the built object (108) from the base device (101) by means of a machining tool in the CNC machine.

Description

technical field [0001] The invention relates to a method of producing an additively manufactured object. Background technique [0002] In additive manufacturing, objects are gradually built on a substrate plate, which thus acts as a solid foundation on which to build three-dimensional objects. [0003] AM objects often require further processing and / or shaping in a subsequent operation, usually somewhere remote from the equipment where the additive manufacturing takes place, so the built object must be moved from the AM machine tool, usually involving Remove from base plate. [0004] Methods for producing objects by additive manufacturing include laser powder bed fusion and electron beam powder bed fusion. In the laser powder bed fusion method, solid particles are coated in thin layers and, depending on the pattern, three-dimensional objects are progressively formed layer by layer by fusing the particles together with one or more laser beams or with an electron beam.
