Abstract
Improved formulations of an interface material are described. These formulations may, in at least some cases, match and/or accommodate dimensional changes in the part and/or support structure throughout thermal processing (e.g., debind and sintering, or sintering only). Furthermore, these formulations may also maintain the property of resisting bonding between the interface and the part and/or support structure while also maintaining a physical separation between the part and support structure. In some cases, an improved interface material may accommodate strain associated with the shrinkage of a part (and optionally support structure) during sintering while also minimally impacting the ability of the part (and optionally support structure) to shrink or otherwise change in dimension. In some cases, the interface material may include one or more fugitive phases that are removed during thermal processing (e.g., through pyrolysis of the fugitive phase(s)).
