Abstract

A rapid prototyping apparatus with a page-width array printing module is disclosed. The rapid prototyping apparatus includes a construction platform, a movable platform and a page-width array printing module. The construction platform has a construction chamber. The length of the construction chamber is ranged from 0.8 m to 1.5 m, the width of the construction chamber is ranged from 0.8 m to 1.5 m, and the height of construction chamber is ranged from 0.8 m to 1.2 m. The movable platform is disposed above the construction platform. The page-width array printing module is installed on the movable platform and synchronously moved along a single direction in a reciprocating motion. The page-width array printing module has plural inkjet head structures disposed thereon, so that a rapid prototyping width-page printing operation is performed.

First claim

What is claimed is:

1 . A rapid prototyping apparatus, comprising:
a construction platform comprising a construction chamber, wherein the length of the construction chamber is ranged from 0.8 m to 1.5 m, the width of the construction chamber is ranged from 0.8 to 1.5 m, and the height of construction chamber is ranged from 0.8 m to 1.2 m; a movable platform disposed above the construction platform; and a page-width array printing module installed on the movable platform and synchronously moved along a single direction in a reciprocating motion, wherein the page-width array printing module has plural inkjet head structures disposed thereon, so that a rapid prototyping width-page printing operation is performed.

2 . The rapid prototyping apparatus according to claim 1 , wherein the length of the construction chamber is ranged from 1 m to 1.3 m, the width of the construction chamber is ranged from 1 m to 1.3 m, and the height of construction chamber is ranged from 0.9 m to 1.1 m.

3 . The rapid prototyping apparatus according to claim 1 , wherein the movable platform is disposed on the construction platform, and the movable platform and the construction platform are movable relative to each other, so that a construction material is pushed to the construction chamber.

4 . The rapid prototyping apparatus according to claim 1 , wherein the page-width array printing module comprises at least one printing platform and the plural inkjet head structures, and the plural inkjet head structures are installed on the printing platform and collaboratively defined as at least one page-width array printing unit.

5 . The rapid prototyping apparatus according to claim 4 , wherein the plural inkjet head structures of the page-width array printing unit comprise respective inkjet chips, and the inkjet chips are disposed on the printing platform and arranged in at least one row and in a staggered form, so that a printing width of the page-width array printing unit is larger than or equal to the width of the construction chamber.

6 . The rapid prototyping apparatus according to claim 5 , wherein the length of the inkjet chips is ranged from 2 inches to 2.25 inches.

7 . The rapid prototyping apparatus according to claim 5 , wherein the inkjet chips of the at least one page-width array printing unit are arranged in at least one row and in a staggered form, and the number of the inkjet chips is ranged from 16 to 35.

8 . The rapid prototyping apparatus according to claim 7 , wherein the number of the inkjet chips arranged in at least one row and in a staggered form is ranged from 20 to 31.

9 . The rapid prototyping apparatus according to claim 3 , wherein the movable platform further comprises a heater, and the heater is configured to heat the construction material after the construction material is spread in the construction chamber.

10 . The rapid prototyping apparatus according to claim 4 , wherein the plural inkjet head structures of each page-width array printing unit are irreplaceable.

11 . The rapid prototyping apparatus according to claim 4 , wherein the plural inkjet head structures of each page-width array printing unit are replaceable.
