This research focuses on computational microstructure to create hydrogel-cellulose ultra-sonication method for the production of additive structures and the stability of the physical characteristics of its cellulose hydrographic composite material in 4D printing. CMC with combined cellulose fibres of high cellulose content for dispersion compounds and fine dehydrated particles allows a 50% fibre matrix hydrolysis. Evaluation of the microstructure composite particle of CMC in 4D surface luminance structure and the profile structure was done. Cross-sectional views and surface roughness, waviness profile of the specimens are extracted and analysed, with the coresonding Gaussian filter for accurate decomposition of particles was carry out. The nanoparticle characterisation of the thermoplastic form was used in the mixed sedimentation process to create an polymer composite structure when analyse. The shrinkage properties of the materials are evaluated to understand the relationship between the deformation according to the time and direction of the 4D printing analysis. The ability of computational ultra-sonication microstructure to be used correctly for 4D printing is demonstrated by evaluating a complex microstructure that can change with time according to the predefined design rules to respond to moisture. The most critical feature is the cellulose gratified in the ultimate material model, which is the amount of cellulose of the ultra-sonication composite specified in the 4D printing materials of 2.5% by mass of hydrogen and 2.5% by mass of CMC.
