Description

一种3D打印机及3D打印系统 One kind of 3D printers and 3D printing systems

技术领域 FIELD

[0001] 本发明涉及打印技术领域,尤其涉及一种3D打印机和3D打印系统。 [0001] The present invention relates to printing technology, and in particular, to a 3D printer, and 3D printing systems.

背景技术 Background technique

[0002] 3D打印是新型快速成型制造技术。 [0002] 3D printing is a new rapid prototyping techniques. 它通过多层叠加生长原理制造产品。 It is through the growth of multi-layer superposition principle of manufacturing products. 它能克服传统机械加工无法实现的特殊结构障碍。 It overcomes the barriers of traditional machining special structure can not be achieved. 可以实现任意复杂结构部件的简单化生产,目前,3D打印技术大致分为下列几种技术:光固化型、熔融沉积成型、层状物体制造、选择性激光烧结、选择性激光熔化等几种,由于光固化型的3D打印技术具有高解析度、成型表面光滑、尺寸精度高等优点,被广泛应用于生产技术。 May implement any complicated simplified structural member production, Currently, 3D printing technology roughly divided into the following technologies: a photocurable type, fused deposition modeling, laminated object manufacturing, selective laser sintering, selective laser melting several, Since the photocurable 3D printing with high resolution, the molding surface is smooth, high precision size, are widely used in the production technology.

[0003]目前,对于光固化成型3D打印技术来说,其实现过程为:利用液晶屏(LiquidCrystal Display,IXD)成像原理,在微型计算机及显示屏驱动电路的驱动下,由计算机程序提供图像信号。 [0003] Currently, for stereolithography 3D printing, its implementation: the use of (LiquidCrystal Display, IXD) imaging principle LCD screen, driven by the microcomputer and the display driving circuit, an image signal provided by a computer program . 在液晶屏幕上出现选择性的透明区域。 Transparent regioselective appears on the LCD screen. 然后在紫外光源的照射下,液晶屏幕的图像透明区域对紫外光阻隔减小,在非透明区域紫外光线被阻挡。 Then the UV irradiation source, transparent region of the liquid crystal screen, an image of reduced ultraviolet light barrier, in the non-transparent area are blocked ultraviolet light. 透过液晶屏的紫外光线构成紫外光图像区域。 Ultraviolet light through an image region constituting the liquid crystal panel ultraviolet light. 在液晶屏幕的表面放置有用于盛放固化液态树脂的容置槽,该容置槽的底部为透明薄膜。 It is placed on the surface of the LCD screen with a curable liquid resin for containing the receiving groove, the receiving groove for the bottom transparent film. 在液晶屏非透明区域由于无紫外线照射,因此该部分的液态光固化树脂没有被紫外光线照射到,仍然保持液态;在与选择性的透明区域对应的位置,紫外光线经过透明薄膜照射到液态光固化树脂,使被紫外光照射的液态树脂产生固化反应,从而使被照射到的液态树脂成为固态,形成需要打印的模型的一个薄层,多次重复此打印过程,即可实现任意复杂结构部件的简单化生产。 In the liquid crystal panel due to the non-transparent area without ultraviolet irradiation, and therefore the portion of the liquid photo-curable resin is not irradiated to the UV light, it remains liquid; selectively position the transparent region corresponding to, ultraviolet light is irradiated through the transparent film into the light liquid curable resin, the liquid resin is irradiated with ultraviolet light to produce the curing reaction, so that to be irradiated to the liquid resin into a solid, forming a thin layer of the model to be printed, the printing process is repeated several times, to achieve any complicated structural member simplified production.

[0004] 但是,由于液态树脂在受到紫外光照射后瞬间聚合成固态的打印层,而未与紫外光接触的树脂保持液态,从而在打印层与树脂槽的底部之间形成真空,使得打印层受到液压和大气压的共同作用力。 [0004] However, since the liquid resin after exposure to ultraviolet light into a solid polymeric instant print layer, without contact with the ultraviolet resin remains liquid, thereby forming a vacuum between the bottom of the printed layer and the resin of the groove, so that the printing layer under the combined force of the hydraulic and atmospheric pressure. 由于目前容置槽的底部一般为玻璃或亚克力材料等刚性材料,无法在容置槽的底部产生一定的形变,因此打印平台若要克服自身重量以及气、液压力而被上提则需要较大的外力,使得打印层与容置槽的底部硬性脱开,影响打印层的脱模效果,进而影响模型的成型效果,无法提升模型表面的光洁度。 As the current receiving groove bottom is typically glass or acrylic material or the like of rigid material can not be generated at the bottom of the receiving groove of a certain deformation, so the printing platform to overcome its own weight, and the gas, hydraulic pressure is put on it can require large an external force, such that the bottom layer and the print receiving groove rigid disengaged influence the release effect printing layer, thereby affecting the shaping model results, can not improve the surface finish of the pattern.
