In order to tap the full potential of MBJ, a deep process understanding is crucial. The aim of this work is to gain a deeper insight of the influence of process parameters on the powder spreading and powder bed heating by using in situ measurements, as a way to create a basis for real-time process control and optimization. This is achieved by generating images of the powder build-up in front of the spreading roller and thermal imaging of the powder bed for each layer. An automated image processing was developed to examine the powder build-up, and the green part properties were evaluated with different powder heating settings respectively. A proper control of the powder spreading and powder bed temperature positively influences powder binder interaction and green part properties, while minimizing the scrap rate.enconference paper
