Additive manufacturing method of casting mold
A method of making a photopolymerizable slurry comprises the steps of: providing a plurality of inorganic salt particles in powder form; wherein the melting point of the inorganic salt is higher than 250 DEG C under atmospheric pressure; and wherein the inorganic salt has a solubility in water higher than 9% w/w at room temperature; providing at least one radiation curable monomer; the at least one radiation curable monomer is in a liquid phase; adding the inorganic salt particles into the liquid composition, and mixing the inorganic salt particles with the liquid composition; obtaining a photopolymerizable slurry, and selectively curing the photopolymerizable slurry to obtain a green body product; degreasing the green body product to obtain a binder-free body product; and sintering the binder-free green body article to obtain a sintered ceramic article; providing a first template mould (1); wherein the first template mold comprises a sintered ceramic article; providing a second mould (2, 2 ', 2' '); wherein the second mold comprises a compartment in which the first template mold can be placed; mounting the first template mould in the compartment of the second mould, thereby obtaining a handling mould (1, 2, 2 ', 2' '); casting a fluid casting material (3, 3 ', 3' ') into the operating mould to obtain an impregnated template mould (8) after curing of the casting material, the impregnated template mould (8) comprising a solid article (9) located at least partially within the first template mould (1); and separating the solid article from the first template mold by dissolving the sintered ceramic article of the first template mold with a suitable solvent, such as water.
一种制造可光聚合的浆料的方法包括以下步骤：提供多种粉末形式的无机盐颗粒；其中在大气压下，无机盐的熔点高于250℃；并且其中在室温下，无机盐在水中的溶解度高于9％w/w；提供至少一种可辐射固化的单体；该至少一种可辐射固化的单体处于液相中；以及将无机盐颗粒加入到液体组合物中，并将无机盐颗粒与液体组合物混合；获得可光聚合的浆料，选择性固化可光聚合的浆料以获得生坯制品；将生坯体制品脱脂以获得无粘结剂的坯体制品；以及烧结无粘结剂的坯体制品以获得烧结陶瓷制品；提供第一模板模具(1)；其中第一模板模具包括烧结陶瓷制品；提供第二模具(2，2'，2”)；其中第二模具包括能够将第一模板模具放置在其中的隔室；将第一模板模具安装到第二模具的隔室中，从而获得操作模具(1，2，2'，2”)；将流体铸塑材料(3，3'，3”)铸塑到所述操作模具中，以在所述铸塑材料固化之后获得浸渗模板模具(8)，该浸渗模板模具(8)包括至少部分位于第一模板模具(1)内的固体制品(9)；以及通过用合适的溶剂，例如水，溶解第一模板模具的烧结陶瓷制品，将所述固体制品从第一模板模具分离。
