METHOD FOR MANUFACTURING AN OBJECT HAVING A COMPLEX SHAPE FROM A CURED ORGANIC OR INORGANIC MATERIAL

摘要

The invention relates to a method for manufacturing a molded object from a mold comprising an internal cavity comprising one or several compartments and at least one removable part present within said internal cavity, said object being in a cured organic or inorganic material, said method successively comprising at least one cycle of following steps:
a) a step for completely filling at least one compartment of the internal cavity of the mold, said compartment having a shape corresponding to all or part of the object, which one wishes to obtain, with a liquid composition which is curable by chemical reaction in order to form said material, said composition comprising at least one solvent;b) a step for curing by chemical reaction said composition within said mold;c) a step for withdrawing at least one removable part of said mold; andd) a step for drying within said mold the cured composition obtained in b),wherein all or part of steps a) to d) may be repeated with a curable liquid composition either identical or different from the one used during said cycle until the molded object is obtained and,wherein said mold, at least during the application of each step d) is a closed chamber, the walls of which forming a boundary between the internal cavity and the outside of the mold are in at least one material able to allow discharge of the gases from said step d).

1. A method for manufacturing a molded object from a mold comprising an internal cavity comprising one or several compartments and at least one removable part present within said internal cavity, said object being in a cured organic or inorganic material, said method successively comprising at least one cycle of:
a) completely filling at least one compartment of the internal cavity of the mold, said compartment having a shape corresponding to all or part of the object, which one wishes to obtain, with a curable liquid composition by chemical reaction for forming said material, said composition comprising at least one solvent; b) curing by chemical reaction said composition within said mold; c) withdrawing at least one removable part from said mold; and d) drying within said mold the cured composition obtained in b), wherein all or part of a) to d) may be repeated with a curable liquid composition either identical or different from the one used during said cycle until the molded object is obtained and, wherein said mold, at least during the application of each d) is a closed chamber, the walls of which forming a boundary between the internal cavity and the outside of the mold are in at least one material able to allow discharge of the gases from said step d).
