Embodiment Construction

[0047] exist figure 1 An embodiment of a device for producing a three-dimensional workpiece 3 is shown in a side view of . Plate 1 is stocked on roll 2. The sheet metal 1 can be lifted layer by layer by means of the roll guide unit 13 . The lowermost sheet metal layer rests on the carrier frame 7 . Notches, not shown in detail, are cut into the lowermost sheet-metal layer, through which sheet-metal residues 8 of the upper sheet-metal layer can fall. However, the sheet metal residue 8 does not have to be forced to fall downwards, but can also be transported away with the sheet metal remainder after the sheet metal 1 has been lifted. The cutting unit 5 and the melting unit 4 form a single unit, the laser, in this exemplary embodiment. The controller 6 transmits the implementation of the movement to the corresponding unit, that is to say along the X and Y axes—that is, in a plane parallel to the section plane—and the Z axis (orthogonal to the section plane), wherein, in the i...

Abstract

Apparatus for producing a three-dimensional workpiece (3) made from meltable starting material, wherein the workpiece (3) is divided into 3D sections (10) by section planes lying parallel to each other, each area section being spatially delimited by an outer contour (25) of the workpiece (3), wherein the starting material is melted using a melting unit (4), wherein the starting material is meltedusing two-dimensional coordinates inside the area sections, wherein the area sections are iteratively constructed layer by layer, wherein the starting material is a sheet-type material, wherein a distance between two area sections (10) lying one on top of the other corresponds to the thickness of a sheet.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for producing a three-dimensional object from a sheet-like raw material and a device according to the preamble of claim 22 for carrying out the method. Background technique [0002] Workpieces are increasingly produced today with the aid of additive production. Additive production was also known as rapid prototyping in the past, but this is no longer an appropriate choice of name due to the capabilities of the new equipment. That is, the new devices are not only suitable for prototyping but increasingly also for series production. The production takes place directly from an amorphous (liquid, powder, etc.) or shape-neutral (ribbon-shaped, linear) material with the aid of chemical and / or physical processes based on internal computer data models. Although a forming method is involved, no specific mold (eg casting mold) storing the corresponding geometry of the workpiece is required ...
