The requisite of exoskeletons are expanding gradually in the field of medical rehabilitation which is mainly due to musculoskeletal disorders, spinal cord injuries, paresis, and military applications and as a consequence of accidents. This study presented a unique exoskeleton design and did a von Mises stress and total deformation analysis on the model. A 3D model of the suggested exoskeleton was built, and the angles of the hip, knee, and ankle joints were adjusted to reflect unique occasions during the sit-to-full-stand and walking transitions, as well as stress analysis for the models. Using the simulation results, two materials were used to make the model steel for internal structural linkages and polylactic acid (PLA). While the model is subjected to a load, an interpretation of the stress distribution is created. The greatest von Mises stress is detected at important points in the exoskeleton model 2 cm above the ankle, indicating the possibility of fracture. The maximum stress for all situations from 82 MPa to 112 MPa was discovered during the simulation. The study shows that utilizing a steel alloy for internal link support and covering with polylactic acid (PLA) layer may be used to develop a lower limb exoskeleton frame
