With the rise of design for additive manufacturing (DfAM) awareness, more efficient and functional designs are being made taking advantage of additive manufacturing (AM) complexity. However, at the same time, since these designs are usually complex enough to not be manufactured using conventional manufacturing methods, they are also complex enough to not be measurable using conventional metrology tools.
To tackle this challenge, a non-conventional metrology tool is usually used, X-ray Computed Tomography (XCT). While XCT still lacks standardisation and needs more research to better generate uncertainty statements, it is becoming more and more popular in the AM field.
