An additive manufacturing apparatus comprises a processing chamber defining a window for receiving a laser beam and an optical module. The optical module is removably-mountable to the processing chamber for delivering the laser beam through the window. The optical module contains optical components for focusing and steering the laser beam and a controlled atmosphere can be maintained within the module.

Additive manufacturing apparatus with a chamber and a removably-mountable optical module; method of preparing a laser processing apparatus with such removably-mountable optical module

A filter assembly for an additive manufacturing apparatus has a housing defining a gas inlet and a gas outlet. A filter element is located within the housing between the gas inlet and the gas outlet. The assembly includes valves that can be actuated to seal the gas inlet and the gas outlet. Additionally the assembly has a fluid inlet for allowing ingress of a fluid into the housing. The assembly allows a filter element, which may contain volatile particles, to be changed safely. By sealing the gas inlet and outlet and flooding the housing with a suitable fluid, volatile particles captured by the filter can be neutralised.

The optical module contains optical components for focusing and steering the laser beam and a controlled atmosphere can be maintained within the module.

An apparatus () for forming a three dimensional object () by layer-wise addition of a build material has a build-support () for supporting the object () during forming and a removable metallic base-layer () that is in the form of a mesh, film, sheet or foil. The base-layer () is removably securable to the build support ().

Additive manufacturing apparatus and method

An apparatus for manufacturing a three-dimensional object by layerwise consolidation of powder comprises a lowerable build platform for supporting the object during manufacture and a sealable chamber for controlling the atmosphere around the object. The apparatus also has gas transport devices, such as pumps and valves. Substantially all of the gas transport devices are maintained within a controlled atmosphere.
