In a recent study a structural hold down component was designed and produced using the particulate injection moulding (PIM) process. The material of choice was titanium due not only to the material properties but also due to the desire to create custom made components for a state-of-the-art marine vessel. On removal from the mould the green parts were seen to have an irregular surface on the top face. The irregular surface presented no through part defects and although the surface irregularities were caused by separation of the two-phases the effect was restricted to the outer surface of the parts. In a more historic study by the author the surface properties of titanium dental implants were modified by the use of adaptive mould inserts during the moulding phase of PIM. These two contrasting studies are considered and have become the basis of a current investigation looking to engineer surface irregularities in an ordered fashion.
The application of meso-machining, and additive manufacture are considered and the functionality which may arise are presented.
