Abstract

The present disclosure describes a number of methods of colouring additively manufactured parts. One such method involves providing a first dyeing liquid, heating the first dyeing liquid to a desired temperature and immersing a surface of an additively manufactured part into the first dyeing liquid. The process is then repeated with a second dyeing liquid so as to alter the colour of the additively manufactured part. Advantageously, by performing multiple, iterative colouring operations, it is possible to achieve a wider range of part colours without having to pre-mix dyes, thereby improving processing efficiency and flexibility.

Abstract

According to the present disclosure, there is provided a method for smoothing a surface of an additively manufactured metal part. The method comprises applying a chemical to a stepped surface of an additively manufactured part to at least soften a binder material supporting unprocessed powder particles of the part and allowing the powder particles at the surface to flow under the influence of gravity into recesses defined by the stepped surface to thereby reduce a roughness of the surface. Advantageously, it has been found that the afore-described method is able to provide a part having an improved surface smoothness.

Abstract

An apparatus (100) for additively manufacturing a part. The apparatus comprises a build bed (104) for supporting a powder material, a powder surface preparation device (106) for preparing a surface of the powder material and an energy emitting device (108) for energising the powder surface based on a desired part geometry. The build bed is controllably moveable along a closed loop transport path which extends around a horizontal axis. Advantageously, it has been found that the provision of a transport path which extends around a horizontal axis provides for more easy access to the parts located on said path. Subsequently, operational efficiency can be improved.
