Abstract: A flame-retardant three-dimension-molded object and a manufacturing method thereof are disclosed. The manufacturing method includes steps of: (a) providing a molded body including plural first pores and plural second pores, wherein the plural first pores communicate inward from an outer surface of the molded body, the first pores and the second pores are partially connected to each other, and a first average pore width of the first pores is greater than a second average pore width of the second pores; (b) immersing the molded body in a flame-retardant solution composed of a flame retardant and a solvent for an immersion time under a negative pressure, so that the flame-retardant solution is introduced into the plural first pores and the plural of second pores; and (c) removing the solvent contained in the plurality of first pores and the plurality of second pores, so as to obtain the flame-retardant three-dimensional-molded object.

Abstract: A printer clean system includes a base, an ink stack assembly, a scraper assembly, a power transmission device and a driving device. The ink stack assembly is disposed on a first accommodation groove. The scraper assembly is disposed on a second accommodation groove. The power transmission device is connected with the driving device, the ink stack assembly, and the scraper assembly. When the power transmission device is rotated to a first angle, the ink stack assembly is brought to an ink stack clean position. When the power transmission device is rotated to a second angle, the scraper assembly is brought to a scraper clean position. When the power transmission device is rotated to a third angle, the ink stack assembly is located at an ink stack return position, and the scraper assembly is located at a scraper return position. Therefore, the pollution can be avoided.

Abstract: An ink cartridge clean device including a housing, a work platform, at least one ink stack and at least one ink absorption pad clean element. The housing has a first sidewall and a second sidewall opposite to each other, and an accommodation groove is defined by the housing. The work platform is disposed in the accommodation groove and has two lateral surfaces opposite to each other, and each lateral surface has at least one stopper. The ink stack is disposed on the work platform, and has an ink absorption pad. The ink absorption pad clean element is rotatably connected with the first sidewall and the second sidewall. When the work platform is adjusted from a first position to a second position, the ink absorption pad clean element is rotated, so that the corresponding ink absorption pad is cleaned, thereby preventing the residual ink from contaminating or blocking the ink cartridge.
