The impact of 3D printing in the medical field has acquired considerable relevance in the scientific and academic communities owing to its growth in both facility adoption and a wide range of applications. Three-dimensional (3D) printing is an emerging technology that is getting substantial interest over the past years in several key areas such as the automotive, aerospace, and especially medicine. The methodology reported for the design of the fiber-matrix structure might be considered as a start to develop new patterns and typologies that may mimic soft tissues. The soft tissue anatomy-mimicking materials are strong enough to withstand the stretching during the flexo-extension. These may be considered as an alternative to replacing cadaver specimens for medical training, pre-operative planning, research and education purposes, and predictive models validation. The proposed anatomical models offer a diverse range of applications. Finally, 3D printing Knee Joint models were tested manually simulating 50 flexo-extension cycles without presenting ruptures. 4 with elastic modules of 0.76-1.82 MPa were chosen for the soft tissues 3D printing. We correlated the pattern of stress-strain curves in the elastic region, stiffness, and elastic modulus of proposed combinations with published literature. Each material combination represents different shore-hardness values between fiber and matrix respectively. 4 (A70-A60) soft tissue-mimicking polymers. Before models 3D printing, uni-axial tensile tests were conducted to obtain the mechanical behaviors for individual No. (iii) Total knee arthroplasty (TKA) model, including custom-made implants. (ii) ACL-R model, incorporating orientations, directions, locations, and dimensions of the tunnels, as well as a custom-made surgical guide (SG) for avoiding graft tunnel length mismatch. Various Computer-Aided Design (CAD) systems and the PolyJet 3D printing were used in the fabrication of three anatomical models wherein fibers matrix structure is mimicked: (i) Anterior cruciate ligament reconstruction (ACL-R) model used in the previous study. In particular, the design of a fibers matrix structure that mimics the soft tissue anatomy. This study reports on a new method for the development of multi-color and multi-material realistic Knee Joint anatomical models with unique features.
