Intelligent Monitoring System (IMS) for Powder Bed Fusion Process

Array

Ideal for operators of powder bed fusion additive manufacturing systems (e.g., service bureaus, equipment owners)
Will serve as the basis for standardisation and certification of AM products.

SC3DP (NTU) X ASTM

Inconsistencies in quality of built parts is preventing the widespread adoption of PBF, especially in industries where product certification is crucial.
Current non-destructive evaluation (NDE) methods are not optimised for AM processes.
Determination of optimum process parameters is mainly empirical and varied by different users without a consensus benchmark.
Current available monitoring systems are mainly developed for a particular process defect and merely used for observation purposes.

To provide a multi-control approach for in-situ observation of a range of process defects in PBF process.
To establish the relationships between defect signatures with a quality-control metric of the fabricated products.

Improved print consistency, part quality and reliability.
Reduced wastage in materials and time invested by providing real-time feedback on the quality of the part being fabricated.
Increase efficiency in manufacturing process, and greater acceptance of PBF parts in industries such as aerospace, automotive and medical
