A method for producing an object by additive manufacturing including receiving in a process chamber a bath of material wherein a surface level of the bath of material defines an object working area, solidifying by a solidifying device a selective layer-part of the material on the surface level, and controlled oxidisation, of waste particles originating from the solidifying of the material, by controlling an oxygen level, such that oxidised waste particles are obtained and ignition of the waste particles is avoided. An apparatus for producing an objet by additive manufacturing.

Method and apparatus for producing an object by means of additive manufacturing

Method for producing an object by means of additive manufacturing, wherein said method comprises the steps of:

A method for calibrating an apparatus for producing an object by means of additive manufacturing including a process chamber for receiving a bath of material which can be solidified by exposure to electromagnetic radiation, a support for positioning the object in relation to the surface level of the bath of material, and a solidifying device for solidifying a selective layer-part of the material on the surface level by means of electromagnetic radiation. A method including providing, on or near the support, a calibration marker that faces the solidifying device, and providing a calibration system with an imaging unit that can be directed to the support. The method further includes a determining step of the position of the calibration marker, making a solidifying marker that relates to the calibration marker and determining a measure for the position thereof, and determining, with the calibration system, at least a correction vector based on the positions of both the calibration marker and the solidifying marker.

Method for calibrating an apparatus for producing an object by means of additive manufacturing, and apparatus for the method

A system for producing an object by means of additive manufacturing including an apparatus, having a storage container for storing powdered material that can be solidified, and a process chamber fluidly connected to the storage container and arranged for receiving at least a part of the powdered material for forming a bath of material within the process chamber. Furthermore, a structure is provided for positioning the object in relation to the surface level of the bath of material. The apparatus also includes a solidifying device for solidifying a layer of the bath of material. A supply device is provided, having a supply container for storing a supply of powdered material that can be solidified, wherein the supply device is fluidly connected, or at least connectable, to the storage container, and wherein the apparatus is arranged for transferring powdered material between the supply container and the storage container.

System for producing an object by means of additive manufacturing

An apparatus for producing an object by additive manufacturing including a chamber for receiving a bath of material solidified by exposure to electromagnetic radiation, a support for positioning the object, and a solidifying device for solidifying a layer of the material. A registering device registers a characteristic of a calibration area related to the surface level of the bath of material and a control unit utilizes the characteristic to control the position of the emitted electromagnetic radiation.

Apparatus for producing an object by means of additive manufacturing

The invention relates to a method for calibrating an apparatus for producing an object by means of additive manufacturing. The apparatus comprises a process chamber, as well as a support for positioning the object in relation to a surface level of a bath of material to be solidified. A solidifying device is arranged for emitting a beam of radiation on the surface level for solidifying a selective part of said material. The solidifying device comprises a focus member for adjusting a focus setting. The method according to the invention comprises the steps of controlling the solidifying device for making test patterns at different focus settings. A calibration system with a sensor unit is used for determining characteristics of test patterns, and a calibrated focus setting is determined based on the characteristics.

Method for calibrating an apparatus for producing an object by means of additive manufacturing

Apparatus for producing an object by means of additive manufacturing, comprising:

Apparatus for producing an object by means of additive manufacturing and method of using the apparatus

Apparatus for producing an object by means of additive manufacturing, comprising: a process chamber for receiving on a build surface of a build plate a bath of powdered material which can be solidified; a support for positioning said build plate in relation to a surface level of said bath of powdered material; a solidifying device for solidifying a selective part of said material; and a homing device for moving said build surface, by said support, to a home position such that said object can be build on said build surface of said build plate, wherein said homing device comprises a homing member which can be displaced along said build surface of said build plate, wherein said homing device is designed for moving said build surface to said home position until a measured force for displacing said homing member is within a pre-determined range. Method for producing an object by means of additive manufacturing.
