Laser Sinterization Aspects of PA2200 Biocompatible Powder - Spinal Cage Application

Abstract:

The paper presents the dimensional aspects of a generic spinal cage build up from PA2200 powder. The cage was manufactured by means of selective laser sintering (SLS) technology, on Formiga P100 machine. The geometric model of spinal cage was designed in SolidWorks by taking into account the requirements that have to be fulfilled by such an implant. The dimensional aspects refer to geometric dimensions along X, Y and Z axes measured on sample parts, when these were placed on a 4x4 matrix on the building plane. The measurements were conducted using a digital caliper having a precision of 0.01, and were presented together with the nominal dimension of the CAD model. In conclusion, some qualitative aspects regarding the setting of the scaling factors were underlined.
