Abstract
A solid freeform fabrication object includes a plurality of parts formed of hydrogels having respective physical properties, wherein the hydrogels having respective physical properties, each having a moisture content of 70 percent by mass or greater, wherein a solvent concentration difference between the hydrogel constituting adjacent parts of the plurality of parts is 5 percent by mass or less.
Claims15
A method of manufacturing a solid freeform fabrication object comprising:
- applying a plurality of hydrogel liquid precursors to form a liquid film while controlling an application position and an application amount of the plurality of hydrogel liquid precursors, each of the plurality of hydrogel liquid precursors having a moisture content of 70 percent by mass or greater and having a solvent concentration difference of 5 percent by mass or less from each other;
- curing the liquid film to obtain a cured film including a plurality of regions formed of hydrogels having respective physical properties;
- and
- laminating the cured film.

A method of manufacturing a solid freeform fabrication comprising:
- applying a first hydrogel liquid precursor containing a water-containing solvent, a polymerizable monomer, and a mineral, and having a moisture content of 70 percent by mass or greater;
- and a second hydrogel liquid precursor compositionally different from the first hydrogel liquid precursor, having a solvent concentration difference of 5 percent by mass or less from the first hydrogel liquid precursor, and having a moisture content of 70 percent by mass or greater, to form a liquid film;
- and
- curing the liquid film formed in the applying.
