Abstract
Official abstract text for this publication.
A rapid prototyping apparatus includes a construction platform, a movable platform, a first lift/lower mechanism and a second lift/lower mechanism. The construction platform includes a powder feeder, a construction chamber and a powder collector. The powder feeder provides construction powder. A rapid prototyping process is performed in the construction chamber. Excess construction powder is collected in the powder collector. The first lift/lower mechanism is disposed under the powder feeder. The second lift/lower mechanism is disposed under the construction chamber and the powder collector. After the rapid prototyping process is completed, the collected excess construction powder in the powder collector and the excess construction powder in the construction chamber are pushed back to the powder feeder by the powder-pushing element, and the construction powder at a topmost layer of the powder feeder is compacted by the powder-pushing element.
First claim
Opening claim text (preview).
What is claimed is: 1 . A rapid prototyping apparatus, comprising: a construction platform comprising a powder feeder, a construction chamber and a powder collector, wherein the powder feeder provides construction powder, a rapid prototyping process is performed in the construction chamber, and excess construction powder is collected in the powder collector; a movable platform disposed over the construction platform and movable relative to the construction platform, wherein a powder-pushing element and a printing module are installed on the movable platform; a first lift/lower mechanism disposed under the powder feeder for moving a first lift/lower platform disposed within the powder feeder in a vertical direction; and a second lift/lower mechanism disposed under the construction chamber and the powder collector for synchronously moving a second lift/lower platform disposed within the construction chamber and a third lift/lower platform disposed within the powder collector in the vertical direction, wherein the powder-pushing element is moved in a direction so as to push back the collected excess construction powder in the powder collector and the excess construction powder in the construction chamber for recycle, and the construction powder at a topmost layer of the powder feeder is compacted by the powder-pushing element. 2 . The rapid prototyping apparatus according to claim 1 , wherein the powder-pushing element is a roller. 3 . The rapid prototyping apparatus according to claim 1 , wherein the second lift/lower mechanism comprises plural support posts, wherein the plural support posts are connected with each other, so that the second lift/lower platform and the third lift/lower platform are linked with the second lift/lower mechanism, wherein the second lift/lower mechanism drives synchronous movement of the second lift/lower platform and the third lift/lower platform in the vertical direction.
