<p>A method of additive manufacturing comprising providing a removable support medium 10 having a number of recesses or openings mounted securely on a build platform 22. Preferably, the support medium may be a woven wire mesh. The method includes depositing a first layer of powdered material 30 into at least some of the recesses; fusing predetermined portions of the first layer of powered material to the support medium; providing a second layer of powdered material and fusing predetermined portions of the second layer to the previously fused portions of the first layer; providing successive layers of powdered material and fusing predetermined portions of each successive layer to previously fused material in order to produce an article; removing the support medium and the article from the build platform; and removing the article(s) from the support medium. The support medium may be reusable or not. In use, preferably none of the powdered material is fused to the build platform; i.e. the article is fused to the support medium rather than the build platform.</p> |
