Classification: CPC B | IPC B

Claim 0:
1. A method, comprising:
forming a layer of polymer particles, the polymer particles having a melting temperature (Tm) of at least 250° C.;
selectively depositing a first fusing agent on a first portion of the layer;
calculating a position, size, and density of an application of a second fusing agent which is to form a heat reservoir in the layer of polymer particles; and
selectively depositing the second fusing agent on a second portion of the layer to form the heat reservoir, wherein a fluid ejection head does not deposit any fusing agent on a third portion of the layer; and
heating the first portion and second portion, wherein the first portion is part of a multiple layer object to be formed and the second portion is not part of the multiple layer object, and the second portion raises a temperature of polymer particles in a subsequent layer.
