Title:

AN IMPLANT AND A METHOD OF MAKING THE IMPLANT AND A METHOD OF CALCULATING POROSITY OF A POROUS MATERIAL

Document Type and Number:

WIPO Patent Application WO/2021/073087

Kind Code:

A1

Abstract:

A method of making an implant having a porous portion is disclosed. The method comprises the following steps: obtaining an artificial foam containing porous portion; scanning the artificial foam to obtain a digital porous model; editing the digital porous model; assembling the digital porous model to form a digital porous block; editing the digital porous block to obtain a digital implant model; forming the implant by printing the digital implant model through a 3D printer. An implant and a method of calculating porosity a porosity of a porous material are also disclosed.
