Embodiment 1

[0038] The specific embodiment of the present invention is as Figures 1 to 2 As shown, a linear extrusion molding device for an extrusion build-up molding 3D printer includes a scanning molding mechanism 1 arranged on the 3D printer. The scanning forming mechanism 1 realizes 3D printing forming through linear extrusion forming. The scanning forming mechanism 1 is arranged on the extrusion accumulation forming type 3D printer, and the scanning forming mechanism 1 is a nozzle.

[0039] The linear extrusion molding device used for the extrusion accumulation molding 3D printer also includes a steering motor 2 . The steering motor 2 is arranged above the scanning forming mechanism 1 and controls its rotation. Steering motor 2 is precisely controlled by digitization. According to printing needs, the steering motor 2 can change the angle between the long side of the scanning forming mechanism 1 and the scanning forming path, thereby changing the scanning forming line width.

Embodiment 2

[0046] The difference from Example 1 is that, as image 3 As shown, the cross-sectional structure of the discharge channel of the nozzle in this embodiment is a strip structure. The elongated structure can be rectangular, such as image 3 Shown in a; The elongated structure can also be an elongated figure whose edge is an irregular curve; as image 3 Shown in b;, the elongated structure can also be oval, as image 3 as shown in c.

[0047] Wherein, when the cross-sectional structure of the discharge channel is an elliptical nozzle, the width at both ends is narrower than that in the middle, which is suitable for printing areas with corners.

[0048] Such as Figures 4 to 8 As shown, one of the cross-sectional structures is described as a nozzle whose two long sides are parallel to each other and the two ends are semicircular arcs. Of course, the cross-sectional structure of the nozzle can also adopt the method of porous linear arrangement, and its technical effect is basi...

Embodiment 3

[0052] The difference from Example 1 is that, as Figure 9 As shown, in this embodiment, the linear extrusion molding device for the extrusion accumulation molding 3D printer is used in the field of construction, and the printing material 3 is concrete. The scanning forming mechanism 1 is a nozzle.

[0053] In this embodiment, the angle between the discharge direction of the nozzle and the scanning plane is less than 90 degrees, so that the discharge direction is toward the rear of the movement direction, thereby slowing down the concrete (or other heavy printing materials) in the nozzle under the action of gravity. The lowering speed can prevent concrete (or other heavy printing materials) from accidentally falling. The cross-sectional structure of the discharge channel of the nozzle is a long strip structure, which has smaller layer patterns when printing vertical objects such as walls or columns, and is easier to smooth by caulking, reducing the workload of production pers...

Abstract

The invention discloses a molding end line-type sweep molding control device for a 3D printer. The molding end line-type sweep molding control device comprises a sweep molding mechanism used for being arranged on the 3D printer, wherein the sweep molding mechanism realizes 3D printing molding in a line-type sweep molding manner. The invention further discloses a molding end line-type sweep molding control method for the 3D printer, which comprises a preparation step of the sweep molding mechanism and a printing step. According to the molding end line-type sweep molding control device and method for the 3D printer, the quality of products molded after printing is guaranteed while the printing speed of the 3D printer is increased; and the method is suitable for 3D printers adopting various molding modes, such as extrusion molding, photosensitive resin laser curing molding, powder laser sintering molding and fused molding, and has a wide application range.

Description

technical field [0001] The present invention relates to the field of 3D printing, in particular to a method and device for controlling molding end line scan molding of a 3D printer. Background technique [0002] The current types of 3D printers include extrusion molding, photosensitive resin laser curing molding, powder laser sintering molding, and fused filament molding. However, these 3D printers all adopt a single-point scanning molding method. For example, the nozzle outlet of an extrusion 3D printer is a perfect circular hole; while the photosensitive resin laser curing 3D printer uses a single beam of laser curing for printing. The single-point scanning forming method limits the scanning forming area on each moving path. [0003] In extrusion-type 3D printers, if the diameter of the nozzle outlet is simply enlarged, the appearance and precision of the molding will be seriously affected, resulting in a decline in product quality. In architectural 3D printers, special...
