Three-dimensional object-forming apparatus

A three-dimensional object-forming apparatus, comprising:

• an in-batches powder-rationing tank system comprising at least one powder-supplying tank, an in-batches rationing roller, and a closing device, wherein the powder-supplying tank is used to store construction powder;
• the in-batches rationing roller provides the construction powder in batches of which each is applied in a required amount, and the closing device controls the dropping application of the rationed construction powder and prevents a trace of the construction powder from leaking out of the inside of the powder-supplying tank;
• a construction tank system comprising a base platform, a powder-loading platform, a construction-forming area, a surrounding dropping-powder area, an elevator apparatus, and a remaining powder auto-collection area, wherein the construction-forming area comprises a construction platform and a construction tank body, wherein the construction platform is used for the loadings of the construction powder and a three-dimensional object formed by stacking layer by layer, secured on the elevator apparatus, and moved up and down inside the construction tank body by the elevator apparatus;
• the surrounding dropping-powder area is set around the powder-loading platform and the construction-forming area to collect remainder of the construction powder;
• and the remaining powder auto-collection area is connected to a bottom space of the surrounding dropping-powder area and allows the reminder of the construction powder to be filtrated by a sieve for recycling;
• a printing powder-applying system comprising a driving component, a movement base, a printing module, and powder-applying device, wherein the movement base is set across the construction tank system and moved transversely by the driving component;
• the printing module is mounted on the movement base, moved back and forth by the driving component for inkjet-printing, and provided with at least one printing cartridge thereon to inkjet-print liquid to the construction powder on the construction platform of the construction tank system for formation;
• the powder-applying device is disposed on a side of the printing module to receive the rationed construction powder dropped in the powder-supplying tank of the in-batches powder-rationing tank system and restricted on the powder-loading platform of the construction tank system, and provided with a powder-applying roller to evenly apply the construction powder of the powder-loading platform onto the construction platform for inkjet-printing formation;
• a rapid drying heating system provided with a temperature sensor for heating while the printing module of the printing powder-applying system is inkjet-printing so as to reduce the time during the formation of the construction powder;
• a printing maintenance device comprising a cleaning unit and a sealing unit, wherein the cleaning unit cleans remaining liquid and adhered powder of the print head on the printing cartridge of the printing module, and the sealing unit is used to seal the print head from being polluted or dried;
• a dust-proof device comprising a dust-proof plate and an extendable dust-proof sheath to separate the driving component of the printing powder-applying system from dust;
• a successive liquid-supplying device comprising liquid-supplying containers, filling containers, and connective pipes, wherein the filling containers provide supplementary inkjet-printing liquid to the liquid-supplying containers, and the liquid-supplying containers and the printing cartridge of the printing module are communicated and drawn by the connective pipes so as to form inkjet-printing operation of successive liquid supplement;
• and
• a powder auto-filtrating and recycling device used to draw and filtrate the floating construction powder while operation for recycling.
