A temperature distribution over the layer of build material may be determined, the temperature distribution indicating, for each of a plurality of locations on the layer of build material, whether fusing agent is present at that location. At least one characteristic derived from the temperature distribution may be compared to a predetermined characteristic. When the compared characteristics differ, an operational characteristic of an additive manufacturing apparatus may be adjusted.Type: ApplicationFiled: April 26, 2016Publication date: April 18, 2019Inventors: Lluis Hierro Domenech, Esteve Comas, Sergi Culubret
