Abstract

A 3 D printer ( 1, 1 a ) includes a material rack ( 20, 20 a ). The material rack ( 20, 20 a ) includes a positioning plate ( 21 ) and a plurality of partition members ( 22 ). The partition members ( 22 ) are fixed to a door plate ( 12, 12 a ) and disposed in an inner area ( 120 ). The inner area ( 120 ) includes a plurality of material receiving compartments ( 121 ). A material tube ( 2 ) includes a pair of wings ( 3 ). The partition members ( 22 ) include positioning recesses ( 220 ) correspondingly. The material tube ( 2 ) is positioned by disposing the wings ( 3 ) on the positioning recesses ( 220 ) in a spanning manner. The material tube ( 2 ) is driven by a printing module ( 40, 40 a ) to move out of the material receiving compartment ( 121 ) and be positioned on the printing module ( 40, 40 a ).

First claim

What is claimed is:

1. A 3D printer ( 1 , 1 a ) comprising:
a machine body ( 10 , 10 a );
a door sheet ( 12 , 12 a ) movably connected to the machine body ( 10 , 10 a );
a material rack ( 20 , 20 a ) fixed to the door sheet ( 12 , 12 a ) and disposed in an inner area ( 120 ) toward an inside of the machine body ( 10 , 10 a ), the material rack ( 20 , 20 a ) including a positioning plate ( 21 ) and a plurality of partition members ( 22 ), the partition members ( 22 ) dividing the inner area ( 120 ) into a plurality of material receiving compartments ( 121 );
at least one material tube ( 2 ), the material tube ( 2 ) including a pair of wings ( 3 ), each of the partition members ( 22 ) including a positioning recess ( 220 ) correspondingly, the material tube ( 2 ) being positioned in the material receiving compartment ( 121 ) by disposing of the pair of the wings ( 3 ) in a spanning manner on the positioning recesses ( 220 ) of two adjacent partition members ( 22 );
a driving module ( 30 , 30 a ) disposed inside the machine body ( 10 , 10 a ); and
a printing module ( 40 , 40 a ) disposed inside the machine body ( 10 , 10 a ) and driven by the driving module ( 30 , 30 a ) to move to the material receiving compartment ( 121 ), the material tube ( 2 ) is driven by the printing module ( 40 , 40 a ) to move out of the material receiving compartment ( 121 ) and be positioned on the printing module ( 40 , 40 a ).

2. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the positioning plate ( 21 ) is disposed perpendicularly on the door sheet ( 12 , 12 a ), and the partition members ( 22 ) are arranged equidistantly and parallelly on one side of the positioning plate ( 21 ).

3. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the printing module ( 40 , 40 a ) includes a loading base ( 41 ) driven by the driving module ( 30 , 30 a ), the loading base ( 41 ) includes a supporting stand ( 42 ) supporting the material tube ( 2 ) and a positioning ring ( 43 ) for insertion of the material tube ( 2 ), and the positioning ring ( 43 ) is located on the bottom of the supporting stand ( 42 ).

4. The 3D printer ( 1 , 1 a ) of claim 3 , wherein the supporting stand ( 42 ) includes a pair of hook arms ( 44 ), and the material tube ( 2 ) is moved to the supporting stand ( 42 ) by engaging of the hook arms ( 44 ) with the pair of the wings ( 3 ).

5. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the positioning plate ( 21 ) includes a positioning portion ( 211 ), and a peripheral surface of the material tube ( 2 ) is in contact against the positioning portion ( 211 ).

6. The 3D printer ( 1 , 1 a ) of claim 5 , wherein the material tube ( 2 ) is a cylinder, and the positioning portion ( 211 ) is correspondingly formed with a curved face.

7. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the door sheet ( 12 , 12 a ) opens and closes in the up-down direction with respect to the machine body ( 10 , 10 a ), and the door sheet ( 12 , 12 a ) is opened in an inclination angle with respect to the machine body ( 10 , 10 a ).

8. The 3D printer ( 1 , 1 a ) of claim 7 , wherein the machine body ( 10 , 10 a ) includes a first sensor ( 13 , 13 a ), the first sensor ( 13 , 13 a ) is actuated by closing the door sheet ( 12 , 12 a ) to cover the machine body ( 10 , 10 a ).

9. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the door sheet ( 12 , 12 a ) opens and closes in the right-left direction with respect to the machine body ( 10 , 10 a ).

10. The 3D printer ( 1 , 1 a ) of claim 9 , wherein the machine body ( 10 , 10 a ) includes a first sensor ( 13 , 13 a ), and the first sensor ( 13 , 13 a ) is actuated by closing the door sheet ( 12 , 12 a ) to cover the machine body ( 10 , 10 a ).

11. The 3D printer ( 1 , 1 a ) of claim 1 , wherein the material rack ( 20 , 20 a ) further includes a plurality of pivot bases ( 24 ) and a plurality of springs ( 25 ) disposed corresponding to the partition members ( 22 ), each of the partition members ( 22 ) includes a supporting member ( 221 ) and an extension arm ( 222 ) in contact against the supporting member ( 221 ), the extension arm ( 222 ) is movably coupled to the supporting member ( 221 ) through the pivot base ( 24 ), and the spring ( 25 ) is resiliently connected between the supporting member ( 221 ) and the extension arm ( 222 ).
