23 Jul Manufacturing method of zinc or zinc alloy or zinc alloy composite material tissue engineering support
Abstract
The invention provides a manufacturing method of a zinc or zinc alloy or zinc alloy composite material tissue engineering support. The method designs and manufactures the multi-hole zinc or zinc alloyor zinc alloy composite material tissue engineering support by means of combination with the 3D printing technology, mould turnover casting and an air compressing seepage method. The method solves the problem that current 3D printing cannot directly manufacture the zinc or zinc alloy or zinc alloy composite material multi-hole support, and alloy 3D printing manufacturing of zinc, zinc alloys andthe like with the low melting point, the low boiling point and high high-temperature volatility can be achieved indirectly. The method comprises the following specific steps that 1, hole parameters are designed through P function, and STL data are obtained through UG modeling; 2, the data are imported into corresponding software of a 3D printer, and printing is carried out to obtain a polylactic acid support; 3, prepared gypsum and salt composite slurry are poured, dried and sintered to obtain a mould turnover body; 4, penetrating of the hole diameter of the mould turnover body is carried out,and the surface is trimmed; 5, the air compressing seepage method is adopted for seeping molten metal in the mould turnover body; and 6, salt is washed away ultrasonically, gypsum mould turning overis carried out, and the multi-hole zinc or zinc alloy or zinc alloy composite material tissue engineering support is obtained.
