The three-dimensional printing - A modern technology used for biomedical prototypes

The three-dimensional printing is a rapid prototyping technology, used to create complex three-dimensional parts directly from a computer model of the part, with no need for tooling. This paper investigates the use of a modern RP technology known as 3-D printing. Using the Rapid Prototyping 3D Zcorp 310 Printer system, we manufactured the prototypes for orthopedic adaptive modular plates based on intelligent materials, human bones and an artificial hand necessary for 'in vitro' simulations, experimental tests, experimental measurements. The material used is a High performance composite powder Zp131. After printing, we used ZMax Resin - High Strength Epoxy Infiltrant System to provide strength and impart specific properties. Using Rapid Prototyping as a fabrication method one can finally obtain functional assemblies. Experimental studies of the staple made of the shape memory alloy named Nitinol are presented. The complexity of the shapes and dimensions of the fabricated parts recommends Rapid Prototyping method as a future fabrication method in different applications and scientific fields of research.
