3-D printing technology appeared in the mid 90s of the 20th century. In fact, 3D printing is the latest rapid prototyping device, using light curing, stacking technology or other technologies. It uses basically the same principle as ordinary printing. The printer is equipped with liquid or powder or other "print material", through computer control to print material layers together, and finally to make the computer blueprint a reality. This printing technique is called 3D stereoscopic printing technology. At present, laser sintering (SLS) and electronic beam processing (EBM) are commonly used for metal 3D printing technology, but these produces produce enormous energy and significantly increase the temperature during modelling (more than 1000°C), which might be higher than the boiling point of the materials. There is limited metal material that can endure such temperatures; therefore the current metal 3D printing equipment has low cost efficiency and melting the metal is difficult to control. Plastic is still the main material used by most 3D printers. This project will study the use of the FDM process , using low melting point metals, zinc being the choice of testing material. Zinc has high degradability and biocompatibility and can be used in formal prostheses and implants. Finally, a thorough discussion on the deference of the learning time will be provided. This document will report the progress of the project and outline what will be expected in the final report.
