[0050] Such as figure 1 As shown, the three-dimensional printer of this embodiment includes a printing platform assembly 10 , a printing head 20 and a controller 30 , and the controller 30 controls the movement of the printing head 20 . The printing head 20 supplies molten filament to the printing platform assembly 10 to form a three-dimensional object. The filament is, for example, ABS (acrylonitrile-butadiene-styrene copolymer), PLA (polylactic acid) and other materials.
[0051] Wherein, the printing platform assembly 10 has a printing supporting platform 11 and an accommodating chamber 12 . Such as figure 2 As shown, the printing support table 11 forms the upper wall of the storage chamber 12. The printing support table 11 is used to accept three-dimensional objects, and the storage chamber 12 is loaded with a cleaning agent, which is used to clean the surface of the three-dimensional object. The type of cleaning agent is not limited, and various types of cleaning agent...

[0061] The three-dimensional printer of this embodiment is basically the same as the above-mentioned first embodiment, and only the differences will be described in detail below.
[0062] Such as Figure 5 As shown, the three-dimensional printer of this embodiment further includes a cutting device 50, and the controller 30 is electrically connected to the cutting device 50, and controls the cutting device to move within a certain range. The cutting device 50 has a cutting blade, the cutting device 50 can move relative to the printing platform assembly 10 , and the cutting blade is used to cut the three-dimensional object on the printing area 13 .
[0063] The printing method of the present embodiment comprises the following steps:
[0064] Y1: Keep the folding plate 14 in the first printing area in a horizontal state, select the first printing area to be opposite to the print head 20;
[0065] Y2: the print head 20 forms the first three-dimensional object 41 in the first pri...

[0073] The three-dimensional printer of this embodiment is basically the same as the above-mentioned first embodiment, and only the differences will be described in detail below.
[0074] The accommodating chamber of this embodiment includes an upper accommodating space, an isolation layer, and a lower accommodating space in sequence, the isolation layer has a gap and a shielding plate, and the shielding plate is used to detachably shield the gap; the three-dimensional printer also includes a circulation device, and the circulation device is used to convert the lower layer The cleaning agent in the storage space is introduced into the upper storage space.
[0075] The printing method includes the following steps:
[0076] S1: Keep the folding plate in a horizontal state, select the first printing area to be opposite to the print head;
[0077] S2: the print head forms the first three-dimensional object in the first printing area;
[0078] S3: The print head moves to the seco...
