Let's not forget what the engineering experts say


“Machine manufacturers recognise that in-process monitoring is a key area for development” (Participant 10). “In simple terms, a layer by layer green-red light system is required indicating, good powder, good spread and good fusion with no defects” (Participant 8). In turn, informative and accurate in-process monitoring, will lead to robust quality statistics.

“Alternatively, in-process thermal monitoring has the potential to avoid the build-up of thermal stresses by closed loop control of contributing build parameters; toolpath, laser power and substrate temperature” (Participant 10).



The PrintRite3D® technology (Sigma Labs Inc., Santa Fe, New Mexico, USA) gives an example of the current industrial standard.


5.10. Summary Eighteen barriers were extracted through case study interviews with representatives of 11 industrial companies across the aerospace, automotive, defence, heavy machinery and biomedical industries.
