A powder for three-dimensional printing including a mixture of soluble adhesive; cement filler including magnesium oxide, and acid additive; and nonreactive ceramic filler. A kit includes a substantially nonaqueous liquid jetting fluid, and a solid powder mixture including soluble adhesive, magnesium oxide, an acid additive, and a nonreactive ceramic filler. A nonaqueous liquid jetting fluid includes up to 50 wt % cosolvents, and an acidic additive. A method for forming a three dimensional article includes providing a layer of a powder mixture including a soluble adhesive, magnesium oxide, an acid additive, and a nonreactive ceramic filler; and applying a substantially nonaqueous liquid jetting fluid including less than 50% water by weight to the powder mixture layer. A solid article formed by three-dimensional printing includes a solidified combination of a powder mixture including soluble adhesive, magnesium oxide, acid additive, and nonreactive ceramic filler; and a substantially nonaqueous liquid jetting fluid.
