摘要

1/1 summary “method of infusion, infiltration or impregnation of a three-dimensional printed object, apparatus for the treatment of three-dimensional printed objects, and, three-dimensional printed object” the invention relates a method of infusing three-dimensional printed objects, free-form manufacturing or additive manufacturing; an apparatus for the infusion of three-dimensional printed objects, of free-form manufacture or additive manufacture; and objects infused with functional thermoplastic polymers, the method is infused with a thermoplastic material introduced under controlled temperature and pressure conditions, and the thermoplastic is penetrated. the object by immersing the object in the thermoplastic, controlling the frequency and amplitude of pressure oscillation to ensure sufficient infusion into the object to at least partially fill the pores or voids and particles or sheets of material from which the object is manufactured. In one embodiment, apparatus 100 facilitates this and comprises a) an infusion chamber (12), wherein the object to be infused with a thermoplastic (110) is infused; b) a reservoir (14) which, in use, is filled with the thermoplastic; c) a healing chamber (16) for heating and curing the object; and d) a controller (18) for controlling the operating functions of the apparatus; the reservoir comprising a heating means (20) and sensors (22, 26, 28) so that the thermoplastics can be fused within the limits of the set temperature parameters (t) and the controller allows sequential infusion steps Or cure in the appliance.
