Abstract
An improved method of producing articles by chemical vapor deposition and articles made therefrom. The method comprises machining an appropriate shape on a suitable substrate, positioning an insert within the shape, depositing a support member material on the shape and the insert to produce a support member, separating the support member from the substrate, chemically vapor depositing an article material on the support member and etching away the support member to produce a free standing article, such as a funnel shaped diamond water-jet mixing tube.
