A method comprising producing a three-dimensional printed article by additive manufacturing with an additive manufacturing printer, the method comprising: producing a support structure or layer which is used with a build layer for forming a green three-dimensional printed article, the support structure or layer being a composition comprising an additive manufacturing feedstock in a filament form, wherein the manufacturing feedstock for the support structure or layer comprises: a pre-ceramic material in a powder form and a polymeric matrix that is a thermoplastic binder that carries the pre-ceramic material blended therein wherein the amount of pre-ceramic material in said feedstock is at least 50% by weight of the feedstock and the amount of thermoplastic binder is ranging from about 0.1% to about 25% by weight of the feedstock material, and wherein the support structure does not soften below 700 degrees °C and does not melt below 1200 degrees °C, heating the green three-dimensional printed article to a temperature to remove the polymeric binder from both the build and support layers through thermal degradation, and in doing so, the build layer is transformed into a ceramic composition by additional thermal processing or sintering, the support layer maintaining shape and structural support of the build layer during this process; and subjecting the ceramic three-dimensional printed article to a solvent to remove the support structure or layer from the three-dimensional article. producing a support structure or layer which is used with a build layer for forming a green three-dimensional printed article, the support structure or layer being a composition comprising an additive manufacturing feedstock in a filament form, wherein the manufacturing feedstock for the support structure or layer comprises: a pre-ceramic material in a powder form and a polymeric matrix that is a thermoplastic binder that carries the pre-ceramic material blended therein wherein the amount of pre-ceramic material in said feedstock is at least 50% by weight of the feedstock and the amount of thermoplastic binder is ranging from about 0.1% to about 25% by weight of the feedstock material, and wherein the support structure does not soften below 700 degrees °C and does not melt below 1200 degrees °C, a pre-ceramic material in a powder form and a polymeric matrix that is a thermoplastic binder that carries the pre-ceramic material blended therein wherein the amount of pre-ceramic material in said feedstock is at least 50% by weight of the feedstock and the amount of thermoplastic binder is ranging from about 0.1% to about 25% by weight of the feedstock material, and wherein the support structure does not soften below 700 degrees °C and does not melt below 1200 degrees °C, heating the green three-dimensional printed article to a temperature to remove the polymeric binder from both the build and support layers through thermal degradation, and in doing so, the build layer is transformed into a ceramic composition by additional thermal processing or sintering, the support layer maintaining shape and structural support of the build layer during this process; and subjecting the ceramic three-dimensional printed article to a solvent to remove the support structure or layer from the three-dimensional article. <EOS>
