To provide an inkjet/powder jet printing process which enables individual control of filling of particles.SOLUTION: A printing system 100 includes a liquid ejector 130 configured to accumulate a curable layer 120 on a surface of a base material 110, in which the layer has a free surface 122 and a boundary surface between the layer and the base material. A preliminary curing device 140 preliminary cures the layer so that a first region 131 closer to the free surface is not cured than a second region 132 closer to the boundary surface. A curing device includes a preliminary curing initiator source 141 configured to provide a preliminary curing initiator 141 polymerizing the layer. The curing device also includes a preliminary curing inhibitor source 142 configured to transmit an inhibitor that inhibits polymerization of the layer. A particle transmission device 160 transmits particles to the layer after the layer has been preliminarily cured.SELECTED DRAWING: Figure 1 【課題】粒子充填の個別の制御を可能にするインクジェット／粉末ジェット印刷プロセスを提供する。【解決手段】印刷システム１００は、基材１１０の表面上に硬化性層１２０を堆積させるように構成された液体エジェクタ１３０を含み、この層は、自由表面１２２及び層と基材との間の境界面を有する。予備硬化装置１４０は、自由表面により近い第１の領域１３１が、境界面により近い第２の領域１３２よりも硬化しないように、層を予備硬化させる。硬化装置は、層を重合する予備硬化イニシエータ１４１を提供するように構成された予備硬化イニシエータ源１４１を含む。硬化装置はまた、層の重合を阻害するインヒビタを送達するように構成された予備硬化インヒビタ源１４２も含む。粒子送達装置１６０は、層が予備硬化された後に、層に粒子を送達する。【選択図】図１
