Method for manufacturing porous metal scaffold using freeze casting, porous metal scaffold manufactured by the same and device for manufacturing porous metal scaffold for living body

摘要

PURPOSE: A porous metal scaffold manufacturing method using freeze casting, a porous metal scaffold manufactured by the method, and an apparatus for manufacturing a porous metal scaffold for a human body are provided to effectively control the mechanical properties of a porous metal scaffold, such as the size of pores, porosity, elastic modulus, and compressive strength. CONSTITUTION: A porous metal scaffold manufacturing method comprises the steps of: preparing slurry by mixing metal powder, a freezing medium, and a dispersing agent, rotating and cooling the slurry to form a freeze-casted product, and removing the freezing medium from the freeze-casted product to form a porous body. The metal powder is selected from a group consisting of titanium, magnesium, iron, aluminum, copper, and an alloy thereof. The freezing medium is selected from a group consisting of water, terpene including comphene and camphor, and a terpenoid based material.
