Direct laser fabrication has been used to produce samples from Ti64 and from a burn-resistant Ti alloy (Ti-25V-15Cr-2Al-0.2C). Experiments have been carried out in which the influence of process variables on the microstructures observed has been investigated. Ti64 tends to form long columnar grains throughout the entire manufacture of parts whereas the burn-resistant alloy tends to form equiaxed grains for virtually all processing conditions. In the burn-resistant alloy a virtually fully dense sample is formed for a wide range of conditions, but in Ti64 it is possible to produce a highly porous structure under some conditions. Work is underway and will be reported, in which it is hoped that the influence of a change in processing conditions can be predicted.
