Fabrication 3d tissue engineering scaffold poly(ethylene) diacrylate filled with aramid nanofiber: mechanical evaluation and toxicity

Abstract

The selection of the optimum scaffold fabrication method becomes challenging due to a variety of manufacturing methods, existing biomaterials and technical requirements. Although, Digital light processing (DLP) 3D printing process is one of the SLA techniques which commonly used to fabricate tissue engineering scaffold, however, there is no report published on the fabrication of tissue engineering scaffold-based PEGDA filled with Aramid Nanofiber (ANFs). Hence, the feasible parameter setting for fabricating this material using DLP technique is currently unknown. This work aims to establish the feasible setting parameter via DLP 3D printing to fabricate PEGDA/ANFs 3D tissue engineering scaffold. Preliminary study has been done to identify the accurate composition and curing time setting in producing scaffold. In this work, the researcher has proved the potential and capability of these novel composition biomaterial PEGDA/ANFs to be print via DLP-3D printing technique to form a 3D structure which is not yet been established and has not reported elsewhere.
