A page-width printing platform comprises a plurality of inkjet head structures collaboratively defined as at least one page-width array printing unit. The inkjet head structures comprise respective inkjet chips disposed on the printing platform and arranged in plural rows and in a staggered form, so that a printing width of the inkjet chips is larger than or equal to a width of a printed pattern. Each of the inkjet chips comprises at least one liquid supply slot, wherein a plurality of liquid ejectors are located at one or two sides of the liquid supply slot along a long axis of the liquid supply slot. At least one monochromatic print liquid is introduced into the construction chamber from the plural inkjet head structures and printed on a construction material within the construction chamber, so that a rapid prototyping width-page printing operation is performed.

Page-width printing platform of rapid prototyping apparatus

A rapid prototyping apparatus includes a construction platform, a movable platform, and a page-width array printing module. The construction platform includes a construction chamber. The movable platform and the construction platform are movable relative to each other. The page-width array printing module includes plural inkjet head structures. The printing platform and the movable platform are synchronously moved along a single direction in a reciprocating motion. The plural inkjet head structures are collaboratively defined as at least one page-width array printing unit. The plural inkjet head structures include respective inkjet chips. The inkjet chips are arranged in plural rows and in a staggered form, so that a printing width of the inkjet chips is larger than or equal to a width of a printed pattern. Moreover, at least one monochromatic print liquid is introduced into the construction chamber from the plural inkjet head structures.

Rapid prototyping apparatus with page-width array printing module

A rapid prototyping apparatus includes a construction platform, a movable platform, a printing module, a cleaning and maintenance module, a construction material spreading element, a heater and a heat shield. A construction chamber is formed in the construction platform. The movable platform and the construction platform are movable relative to each other. The printing module is installed on the movable platform, and includes at least one printhead unit. The cleaning and maintenance module is installed on the movable platform. The construction material spreading element is installed on the movable platform for spreading a ceramic construction material to the construction chamber. After the ceramic construction material is spread in the construction chamber, the construction material is heated by the heater. After the printhead unit performs a printing operation, the printhead unit is cleaned and maintained by the cleaning and maintenance module.

An automatic powder recycling apparatus includes a housing, a plurality of isolation elements, an air-blowing device, a powder filtering member, a recycling member and an air-inhaling device. A sealed space is defined within the housing. The air-blowing device is disposed within the sealed space for removing the powder attached on the surface of the finished product. The air-inhaling device is in communication with the first receptacle for allowing the first receptacle to be in a negative pressure state. When the powder on the finished product is removed by the air-blowing device and directed to the powder filtering member by the air-inhaling device, the powder is filtered and blocked by the powder filtering member. When the air-inhaling device is disabled, the powder blocked by the powder filtering member naturally falls down to the recycling member.

Automatic powder recycling apparatus

An inkjet head manufacturing method includes the following steps. Firstly, a multilayered structure with a plurality of microstructure layers is provided. The alignment check holes of the microstructure layers are concentric and have different diameters. Then, the microstructure layers are stacked together and the microstructure layers are aligned with each other according to the concentric and different-diameter alignment check holes, wherein a dry film layer is sandwiched between every two adjacent microstructure layers. The preset slots of the microstructure layers are collectively defined as inlet flow channels, ink chambers, pressure cavities and outlet flow channels. Then, the multilayered structure is assembled and positioned through the dry film layers by a thermal compression process. Then, a cutting knife is used to linearly cut the actuator plate over a spacer between every two adjacent pressure cavities and along a path parallel with rims of the pressure cavities.
