Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a small three-dimensional synthetic material forming machine and a forming temperature control method thereof. Background technique [0002] 3D molding is a kind of rapid prototyping technology. It is a technology based on digital model files and using adhesive materials such as rubber, resin or plastic to construct objects by layer-by-layer accumulation. In 1991, CimaM.J. and Scans E.M. of the Massachusetts Institute of Technology applied for a patent on three-dimensional molding, and then the three-dimensional molding system based on this patent design and research used HP thermal bubble nozzles, which can spray adhesive materials to make Powder bonding molding, whose working principle is similar to the traditional inkjet molding process, is a rapid prototyping technology based on the principle of droplet jetting. The current 3D molding technology is base...

Problems solved by technology

However, the small-sized three-dimensional synthetic material molding machine in the prior art is in the research and development stage, and the traditional three-dimensional molding system has a complex structure, high cost of implementation, large space occupation, inconvenient portability, and inconvenient use; moreover, the conventional three-dimensional molding system The 3D molding system mostly uses a small, Italian-made open-source microcontroller, namely the ardiuno board, as the hardware platform for the molding machine control circuit; Motorola's 68000 control board, MCS-51 series single-chip microcomputer, MSP430 single-chip microcomputer, 80C196 single-chip microcomputer, etc. As the main controller of the molding machine, the controllers in the prior art have defects and deficiencies such as poor scalability, low execution efficiency, poor performance, high cost, and poor versatility; There is no set of methods for temperature control with simple steps, convenient implementation and high real-time control method. If the molding temperature control is not good enough, it will affect the quality and efficiency of molding.
