In this approach, the building block are powder particles (calcium carbonate / plaster), which are bound together at specific pixels by inkjet printing a binder ink on top of the particles, layer-by-layer. The obtained structures are white and porous and in order to fully harden the structures it is dipped in epoxy glue for the final hardening.
Examples for printed samples:
Cost of materials (powder and ink): 1.30 NIS per gram, and 1.65 NIS per gram with final hardener.
Cube printed composed of powder particles without hardening, 21.2 g, 27.60 NIS
Lion printed composed of powder particles after hardening, 156.3 g, 254.85 NIS.
