AI Technical Summary
Current additive manufacturing techniques cannot produce objects with mechanical and visual properties similar to soft bodily tissues, as the hardest materials created have a Shore hardness of about 30, which is higher than that of soft tissues and do not accurately mimic the properties of soft bodily organs.
The method involves dispensing elastomeric curable formulations with specific properties, such as the Tango and Agilus families, to create objects with Shore A hardness lower than 10 or Shore 00 hardness lower than 40, using a combination of modeling materials and support materials in additive manufacturing processes like 3D inkjet printing, forming voxel elements with a fibrous pattern and interlaced locations to achieve the desired mechanical and visual properties.
This approach allows for the successful fabrication of three-dimensional objects that mimic the structural, visual, and functional properties of soft bodily tissues, providing the required hardness, dimension stability, and tear resistance while resembling the appearance of soft tissues and organs.
