Abstract:
A variety of additive manufacturing techniques can be adapted to fabricate a substantially net shape object from a computerized model using materials that can be debound and sintered into a fully dense metallic part or the like. However, during sintering, the net shape will shrink as binder escapes and the base material fuses into a dense final part. If the foundation beneath the object does not shrink in a corresponding fashion, the resulting stresses throughout the object can lead to fracturing, warping or other physical damage to the object resulting in a failed fabrication. To address this issue, a variety of techniques are disclosed for substrates and build plates that contract in a manner complementary to the object during debinding and sintering.

Claim (Index 20):
A system comprising:\n a build plate; a supply of a build material, the build material including a powdered material for forming a final part and a binder system including one or more binders, wherein the one or more binders resist deformation of the build material during fabricating, debinding, and sintering of the build material into the final part; and an additive fabrication system configured to fabricate an object on the build plate from the build material, the additive fabrication system imparting a net shape to the build material based on a computerized model, wherein the additive fabrication system is configured to provide a build surface having a shrinkage rate matching at least one of a debind shrinkage rate and a sintering shrinkage rate of the build material.
