In the present study, a nano composite PMMA was prepared with the help of hot plate magnetic stirring and probe sonication at different loading conditions of reinforcement material SS 316 L. In order to study the effect of independent factors (the amount of reinforcement material, stirring speed, and sonication time) on response variables, the central composite experimental design of response surface methodology was utilized. The microstructure (surface morphology and topography) was analysed by SEM and AFM, resulting in homogeneous dispersion of nano particles. The analysis of the RSM results indicated that the experimental data were most accurately represented by a quadratic polynomial model, with regression coefficient values exceeding 0.960 for all the responses. The optimum preparation conditions for PMMA nano-composite to achieve the best specific wear rate and compression strength were found to be as follows: the addition of 1.16% (w/w) of reinforcement material SS 316 L, a stirring speed of 1200 rpm, and a sonication time of 29.6 min. The results of this study hold great significance in the fabrication process of long-term provisional dental crowns and bridges.
The process flow chart consists of 3 Phases. Phase 1: Preparation of nanocomposite of PMMA resin and SS 316 L nanopowder using magnetic stirring and probe sonication. Phase 2: Fabrication of nanocomposite using resin 3D printer and investigation of mechanical properties (compression strength and wear rate) and microstructure (SEM and AFM images). Phase 3: Result analysis and validation using response surface methodology
A nano composite was prepared using SS 316 nanoparticles as reinforcement material.
The effect of independent process parameter was investigated using RSM model.
The compression strength and wear rate of nanocomposite were studied.
The microstructure was visualised by using SEM and AFM images.
The noval fabricated 3D printable nanocomposites was found more effective.
