Abstract

A system and method of printing a biotic material based object from a biotic material originated from swiftlet's edible bird nest, includes providing parameters of an object for printing; controlling a deposition of a fluid biotic material comprising a blend of water and nanometre-sized and/or micrometre-sized swiftlet edible bird nest particles to form the said object, wherein at least an outer surface region of the fluid biotic material is converted to a solid or semi-solid region after deposition & dehydration; and controlling a dehydration of said deposited fluid biotic material by accurately exposing the said deposited fluid biotic materials to a controlled environment. During and/or after the fluid biotic material deposition, an ultra-low humidity air stream is specifically channelled onto the freshly deposited fluid biotic material to accelerate the dehydration process and minimise the deposited biotic material based object or structure from deforming.
