Problems solved by technology

However, the above-mentioned light-curable materials usually have a certain viscosity (viscosity), that is, most of the general light-curable materials have low fluidity, so that the printing platform immersed in the light-curable material will be subjected to uneven buoyancy, resulting in The printing platform is tilted instead of level, reducing the fineness of printing

Embodiment Construction

[0009] see Figure 1A and Figure 1B , the 3D printing device 100 includes a removing mechanism 110 , a putting base 120 , a printing platform 130 , a projector 140 and a driving mechanism 150 . The accommodating seat 120 can accommodate the photocurable material M1, and has a plane 121, which can be used to place the photocurable material M1. The photocurable material M1 can be a liquid with good fluidity or a fluid that is not easy to flow. for the limit.

[0010] The removal mechanism 110 has a contact end 111 located above the plane 121 for contacting and removing a part of the photo-curable material M1, wherein the removal mechanism 110 is, for example, a scraper. The driving mechanism 150 is connected to the removal mechanism 110, and drives the removal mechanism 110 to move on the plane 121, so that the contact end 111 of the removal mechanism 110 can remove part of the light-curable material M1, so that the light on the plane 121 The thickness of the cured material M...

Abstract

A three-dimensional line printing device comprises a plane and a removing part, wherein photocuring materials are placed on the plane, the removing part is provided with a touch end located above theplane and is used for touching and removing part of the photocuring materials, and the thickness of the photocuring materials after part of the photocuring materials are removed by the removing part is larger than the thickness of a curing-forming pattern. Therefore, the size of a line printing platform soaked in the photocuring materials can be reduced to greatly weaken buoyancy force, the line printing platform is prevented from inclining due to applying of nonuniform buoyancy force, and the problem that the line printing fineness is lowered due to the fact that the line printing platform isnot horizontal is solved.

Description

technical field [0001] The invention relates to a printing device, in particular to a three-dimensional printing device. Background technique [0002] The current three-dimensional printing technology has developed a bottom-up stereolithography apparatus (bottom-up StereoLithography Apparatus, boot-up SLA), which can produce fine finished products. When the pull-up 3D lithography device is printing, the printing platform will be lowered and completely immersed in the photo-curable material. Afterwards, the photo-curable material is irradiated and cured, and the printing platform will slowly rise to form a multi-layered solid pattern on the bottom surface of the printing platform, thereby completing the printed product. However, the above photo-curable materials usually have a certain viscosity (viscosity), that is, most of the general photo-curable materials have low fluidity, so that the printing platform immersed in the photo-curable material will be subjected to uneven b...
