Abstract
A process for manufacturing an object by laser sintering comprises: (i) selecting a powder comprising a polymeric material having a repeat unit of formula—O—Ph—O—Ph—CO—Ph—  Iand a repeat unit of formula—O—Ph—Ph—O—Ph—CO—Ph—  IIwherein Ph represents a phenylene moiety; and (ii) selectively sintering the powder to produce the object. It is found that the polymer used can be advantageously recycled and blended with virgin material to produce a blend which has very similar mechanical properties and crystallinity compared to the virgin material. Thus, the polymer may be cost-effectively used in laser sintering.
