The Status Quo Of 3D Printing Rapid Prototyping Technology
Z Corp in the United States and Riken Institute in Japan have developed RP devices based on inkjet printing technology that can produce color prototypes. The system uses four different colors to produce eight different tones. The prototype can show the thermal stress distribution in three dimensions. By cutting the prototype, you can find the temperature and stress changes in the prototype. Finite element analysis is especially useful. TNO in the Netherlands and BMT in Germany are also studying RP color manufacturing technology.
The United States Sanders Prototype Inc is based on the hot melt metal jet technology of the Pattern Master is one of the fastest RP equipment. The production range is 300mm × 150mm × 220mm, the user can make prototypes and verify the design in real time, and then the molded parts can be obtained. The surface accuracy of the molded part is 0.08 to 0.16 mm.
Three Dimensional Printing (3DP) rapid prototyping technology is a RP technology based on the principle of micro-ejection, which ejects liquid droplets from nozzles and prints (stacks) layer by layer in a certain path. 3DP is considered to be one of the most viable new technologies in the RP industry, with good development potential and broad application prospects. It has broad application prospects in the fields of biomedical engineering, pharmaceutical engineering and micro-electromechanical manufacturing.
