Abstract
A tool-less method for making molds, cores, and temporary tools includes the steps of providing a volumetric build system, making a CAD model of a three-dimensional object, selecting a build material including an untreated sand, selecting a binder comprising a polymeric carbohydrate, and applying, by the volumetric build system, the binder onto the build material to three dimensionally print the object, wherein the object is adapted for being a mold, a core, or a temporary tool.
Claims26
A tool-less method for making molds, cores, and temporary tools, said method comprising the steps of:
- providing a volumetric build system;
- making a CAD model of a three-dimensional object;
- selecting a build material comprising an untreated sand;
- selecting a binder comprising a polymeric carbohydrate;
- applying, by the volumetric build system, the binder onto the build material to volumetrically build the object, wherein the object is adapted for being a casting mold, a casting core, or a temporary tool.
A tool-less method comprising the steps of:
- obtaining a representation of a three-dimensional object;
- selecting a build material comprising an untreated sand;
- selecting a binder comprising a starch nanoparticle;
- and
- using the representation of the object, the build material, and the binder to volumetrically build the object, wherein the object is adapted for being a casting mold, a casting core, or a temporary tool.
