A building material for use with a 3D printer comprises powdered calcium carbonate extracted from naturally formed calcium based substances obtained from biological sources, such as eggshells, molluscs and crab shells. The material may be mixed with one or more of an absorbent, an adhesive and an additive to obtain a composite powder for use in 3D printing. A 3D printing apparatus (100, fig 1) may comprise a curing machine 102 for preparing a powdered calcium carbonate extracted from naturally formed calcium based substances obtained from biological sources, and a 3D printer 104 that uses powdered calcium carbonate obtained from the curing machine to form objects, such as via powder bed printing, inkjet printing, fused depositing modelling (FDM), or selective laser sintering (SLS). The curing machine may include a cleaning chamber 302, a grinding chamber 304, and a packing chamber 306. The packing chamber may determine the quantity of one or more of an absorbent, an adhesive and an additive to be mixed with the powder from the grinding chamber to obtain a composite powder, and then mix and pack the composite powder in a cartridge.
