A portable power tool has a tool holder, a motorand an electro-pneumatic striking mechanism. The striking mechanism includes an excitation piston, a striker, a pneumatic chamberfor coupling the strikerto the excitation pistonand an anvilwhich is arranged in the striking directiondownstream of the strikerand is provided for transmitting a blow of the striker to the tool. The anvil is hollow. The hollow interior spaceis closed in the striking directionand counter to the striking direction

Portable power tool

A method for a workpiece comprising a material composed of a base material and an additive is disclosed, the method including spreading a granular material in superimposed layers. The granular material contains the base material and an organic binder. An ink contains a solvent for dissolving the binder, and a suspension of the additive. Using the ink, patterns are printed onto individual layers. The ink dissolves the binder in the region of the patterns, and introduces the additive in the region of the patterns. The patterns in the layers together produce a three-dimensional shape of the workpiece. The solvent is expelled so that the granular material is connected by the binder and the additive is fixed. Granular material unwetted by the solvent is removed to reveal the green compact of the workpiece. The green compact is thermally treated to convert the base material and the additive into the material.

Additive manufacturing method

A method for the layered production of a green body () from powdery material, including insert elements which are placed at defined positions in the powdery material, in which the green body () is segmented in a building direction () into N, N&#x2265;2 consecutive, cylindrical cross-sectional areas () made up of a two-dimensional cross-sectional surface and a layer thickness. Setting areas for the insert elements are defined in the cross-sectional areas of the green body () which include the defined positions for the insert elements, and loose powder particles surrounding the setting elements are at least partially bonded to each other before the insert elements are placed into the powdery material.

Method for producing a green body layer by layer from pulverous material by means of insert elements arranged in a defined manner

A method for the layered production of a component () from powdery material including loose powder particles, based on three-dimensional data of the component (), including the method steps: the component () is segmented in a building direction () into N, N&#x2265;2 consecutive, cylindrical cross-sectional areas () made up of a two-dimensional cross-sectional surface and a layer thickness; N powder layers of the powdery material are applied to a building plane perpendicular to the building direction (); the loose powder particles in the cross-sectional areas () of the component () are at least partially bonded to each other and to the underlying cross-sectional area and; loose powder particles arranged within one cross-sectional area or within multiple consecutive cross-sectional areas in the building direction () are at least partially removed from the component () during the layered production of the component ().

Method for layered production of a component from a powdery material

A method for the layered production of a green body from powdery or paste-like material, including cutting elements based on three-dimensional data of the green body, the green body being segmented in a building direction into N (N&#x2265;2) consecutive cylindrical cross-sectional areas made up of a two-dimensional cross-sectional surface perpendicular to the building direction and a layer thickness in parallel to the building direction, including the method steps: the cross-sectional areas of the green body are each divided into material areas, and setting areas, in which the cutting elements are situated; the material areas in the building direction are applied to a building plane situated perpendicularly to the building direction, until at least one cavity formed by one setting area or by multiple consecutive setting areas in the building direction, has the necessary insert height for placing the cutting elements; and at least one cutting element is placed into the cavities having the necessary insert height for placing the cutting elements.
