In this study AW was used to fabricate 3D parts for bone applications by an indirect three dimensional printing (3DP) technique.

Wollastonite - Wikipedia

Wollastonite is a calcium inosilicate mineral (CaSiO3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks. Associated minerals include garnets, vesuvianite, diopside, tremolite, epidote, plagioclase feldspar, pyroxene and calcite. It is named after the English che

Environmental Uses – Canadian Wollastonite

The weathering process of wollastonite supplies calcium to both plants and to the soil system. In the soil, calcium combines with carbonic acid to create calcium carbonates, increasing carbon storage in the soil. Multiple projects are underway evaluating wollastonite as a means of reversing declines in Sugar Maple stands in Ontario and Quebec.
