Abstract

A stereolithography 3D printer (10) includes: a transporting mechanism (1) having a translucent conveyor belt (11) with its top divided into a discharge area (13) and a receiving area (14); a discharging mechanism (2) installed in the discharge area (13) and including a first material box (21) and a discharge nozzle (22) corresponsive to the first material box (21), and the first material box (21) having a discharge port (211); and a recycling mechanism (3) installed in the receiving area (14) and including a second material box (31) and a receiving sucker tip (32), and the first material box (21) and second material box (31) being disposed adjacent or attached to the translucent conveyor belt (11), and the receiving sucker tip (32) being corresponsive to the second material box (31), and the second material box (31) having a receiving port (311).

Claims

1. A stereolithography 3D printer, comprising:

a transporting mechanism (1), including a translucent conveyor belt (11) with a top divided into a discharge area (13) and a receiving area (14) and a curing area (15) defined between the discharge area (13) and the receiving area (14);

a discharging mechanism (2), installed in the discharge area (13), and including a first material box (21) and a discharge nozzle (22), and the first material box (21) being disposed adjacent or attached to the translucent conveyor belt (11), and the discharge nozzle (22) being configured to be corresponsive to the first material box (21), and the first material box (21) having a discharge port (211) formed on a side thereof;

a recycling mechanism (3), installed in the receiving area (14), and including a second material box (31) and a receiving sucker tip (32), and the second material box (31) being disposed adjacent or attached to the translucent conveyor belt (11), and the receiving sucker tip (32) being configured to be corresponsive to the second material box (31), and the second material box (31) having a receiving port (311) formed on a side thereof, and the discharge port (211) and the receiving port (311) being configured to be corresponsive to each other, and the translucent conveyor belt (11) moving in a direction from the discharge port (211) towards the receiving port (311);

a moving platform (4), installed in the curing area (15), and capable of moving close to or away from the translucent conveyor belt (11); and

a curing light source (5), configured to be corresponsive to the curing area (15).

2. The stereolithography 3D printer of claim 1, wherein the moving platform (4) has a bearing surface (41) disposed opposite to the translucent conveyor belt (11), and the bearing surface (41) has a surface friction coefficient greater than the surface friction coefficient of the translucent conveyor belt (11).

3. The stereolithography 3D printer of claim 1, wherein the discharge port (211) has an opening width (a) smaller than the opening width (b) of the receiving port (311).

4. The stereolithography 3D printer of claim 1, wherein the discharging mechanism (2) further includes an adjustable valve (24) installed in the discharge port (211) and capable of moving close to or away from the translucent conveyor belt (11).

5. The stereolithography 3D printer of claim 4, wherein the adjustable valve (24) has a scraper (241) extended in a direction towards the translucent conveyor belt (11).

6. The stereolithography 3D printer of claim 1, wherein the translucent conveyor belt (11) is a translucent film (111), and the transporting mechanism (1) further includes two reels (12), and both ends of the translucent film (111) are wound around the two reels (12) respectively.

7. The stereolithography 3D printer of claim 1, wherein the discharging mechanism (2) further includes a plurality of material tubes (23) installed at the top of the discharge nozzle (22) and communicated to the discharge nozzle (22).

8. The stereolithography 3D printer of claim 1, wherein the recycling mechanism (3) further includes a plurality of suction tubes (33) installed at the top of the receiving sucker tip (32) and communicated to the receiving sucker tip (32).

9. The stereolithography 3D printer of claim 1, wherein the first material box (21) and the second material box (31) are in a rectangular shape, and the discharge nozzle (22) and the receiving sucker tip (32) are in a long stripe shape.

10. The stereolithography 3D printer of claim 1, wherein the curing light source (5) is installed under the translucent conveyor belt (11) and the curing area (15).
