True-color 3D surface metrology for additive manufacturing using interference microscopy (2017)
Conference Proceeding

Coherence scanning interferometry (CSI) is widely used for surface topography characterisation. With the ability to measure both rough surfaces with the high slopes and optical finishes, CSI has made contibutions in fields from industrial machining t...

Optimisation of surface topography characterisation for metal additive manufacturing using coherence scanning interferometry (2017)
Conference Proceeding

The surface topography of metal additive manufactured (AM) parts can be challenging to measure due to the presence of complex features, such as high slopes, step like recesses and protuberances, and local variations in reflectance. Recent innovations... Read More about Optimisation of surface topography characterisation for metal additive manufacturing using coherence scanning interferometry.

Feature-based characterisation of laser powder bed fusion surfaces (2017)
Conference Proceeding

A novel algorithmic pipeline for the automated identification and dimensional/geometric characterisation of topographic formations of interest (surface features) is proposed, specifically aimed at the investigation of signature features left by laser...

Coherence scanning interferometry for additive manufacture (2017)
Conference Proceeding

Additive manufacture (AM) of metal components is a rapidly maturing technology; but given the large number of interrelated process parameters, it remains difficult to control to high precision. It has been observed that processing conditions may be a... Read More about Coherence scanning interferometry for additive manufacture.

X-ray computed tomography of additively manufactured metal parts: the effect of magnification and reconstruction sampling on surface topography measurement (2017)
Conference Proceeding

X-ray computed tomography (XCT) has recently become recognised as a viable method of surface topography measurement for additively manufactured (AM) metal parts [1–5]. AM is capable of producing internal features that are inaccessible to other surfac...

A metrology horror story: the additive surface (2017)
Conference Proceeding

Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography (2017)
Conference Proceeding

Recent advances in X-ray computed tomography (XCT) have allowed for measurement resolutions approaching the point where XCT can be used for measuring surface topography. These advances make XCT appealing for measuring hard-to-reach or internal surfac... Read More about Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography.
