Extrusion-based 3D food printing: printability assessment on the effect of process parameters on printing output of white chocolate D.M. Parid, M.A.P. Mohammed, A.S. Baharuddin, N.A.A. Rahman, A.T. Talib, M. Wakisaka Food Research, 2025 An important aspect of 3D food printing is printability, which is one of the critical parameters for judging the success of an extrusion-based 3D printing process. The printability characteristics include the effect of the dead zone/static zone, analysis of die swell, extrudate stacking and rheology behaviour of extruded food. In this study, white chocolate was used with a commercial syringe-based 3D food printer. The rheological study of white chocolate was conducted using a rotational rheometer under the flow peak hold mode. The results revealed that process parameters such as temperature, extrusion speed and type of nozzle were critical for the successful printing of white chocolate. For better printability, appropriate process parameters need to be applied. Hence, this paper focused on identifying the process parameters, including temperature, extrusion rate and type of nozzle used, that will affect the printability performance of white chocolate. By understanding how these factors impact the printability of white chocolate, optimisation of the printing process can be done to achieve more precise and reliable results. This research contributed to the development of efficient and high-quality 3D-printed food products using white chocolate as a base material. Further optimisation of these parameters enables the food 3D printer to create 3D chocolates with appropriate quality.
Oil Palm Fibers Micromechanics: Anisotropic Behavior Suhaiza Hanim Hanipah, Ahmad Tarmezee Talib, Mohd Afandi P Mohammed, Azhari Samsu Baharuddin, Minato Wakisaka Journal of Natural Fibers, 2022 The anisotropic behavior of oil palm fibers (OPF) was investigated using finite element models, which were used to fit experimental data from stalk and mesocarp oil palm fibers under different tensile deformation modes. The experimental results showed damage to oil palm fibers due to deformation, viscoelastic behavior from reduced stress at fixed strain, as well as anisotropic behavior from tensile-twisting tests. In this work, the finite element models were improved from the previous works on the fiber mechanics by including Fung orthotropic and Prony series viscoelastic functions. The developed single-element finite element model agreed with experimental tensile data under cyclic, stress-relaxation, and step-relaxation modes. The modeling parameters from the single element model and information from the experimental work were then used to simulate the deformation of a virtual fiber obtained from µ-CT analysis, as well as its composite model.
Effect of silica bodies on oil palm fibre-polyethylene composites Suhaiza Hanim Hanipah, Farah Nadia Omar, Ahmad Tarmezee Talib, Mohd Afandi P Mohammed, Azhari Samsu Baharuddin, Minato Wakisaka Bioresources, 2020 The influence of natural protrusion, also known as silica bodies, was studied in relationship to sliding resistance reinforcement in an oil palm fibre-polyethylene composites. Experimental work on oil palm fibres-LLDPE composites (using fibres with and without protrusions) was conducted, which included x-ray microtomography (µ-CT scan), scanning electron microscopy, and degree of grafting analyses. A finite element micromechanical model was then developed using information from the experimental results to simulate fibre pull-out from the matrix. Microscopic observation after mechanical tests of the composites showed crater marks due to silica bodies in contact with the matrix, whereas fibres were uniformly distributed inside the matrix from the µ-CT scan. Likewise, the degree of grafting analysis showed a positive influence of silica bodies as an additional reinforcement to the composites. These were further supported by the modelling results of fibre pull-out, which showed a clear difference between models with and without silica bodies.
