METHOD AND APPARATUS FOR DELIVERY OF CEMENTITIOUS MATERIAL
First Claim
1. A multi-layer construction method is characterised in that construction of each layer comprises the steps of:
- providing a cementitious material;
delivering said cementitious material to a nozzle;
indexing said nozzle along a pre-determined path; and
applying said cementitious material to a work surface by extrusion through said nozzle;
these steps being repeated for each additional layer of construction required.

Abstract
An apparatus (100) for performing a multi-layer construction method using cementitious material has a reservoir (4) for containing cementitious material. The reservoir (4) is coupled to a print head (6) with a delivery nozzle (13). The delivery nozzle (13) can be moved by a robotic arm assembly (1) to index the nozzle (13) along a predetermined path. Flow of the cementitious material from the reservoir (4) to the nozzle (13) and to extrude the material out of the nozzle (13) is controlled in conjunction with indexing of the nozzle (13). A support material, an accelerating agent and a cartilage material may also be deposited from the print head (6).
