Abstract

Stereolithography - also known as SLA 3D printing is one of the most popular, emerging and widespread technology in the world of additive manufacturing. This technique basically works with the help of a high powered ultraviolet laser, which is used to harden the liquid resin by adding progressive layers on the base of built-in platform present in the tank to create the desired 3D shape. Our SLA 3D printer is generally composed of five main sections which involves a tank filled with photopolymer resin, a built-in platform, ultraviolet LEDs, Raspberry Pi and Arduino Uno. Our printer employs a hybrid approach of 3D-printing in which a modified LCD is used as a barrier between the UV LED and resin tank as well as the whole idea focuses on creating an cost effective printer. The LCD screen acts as a stencil for shaping the layers of the 3D model. The ultraviolet light from light source shines directly, in a parallel fashion, onto the build area in order to create the desired 3D model in a layer-by-layer fashion.

UV LED树脂3D打印机的设计

立体光刻技术(也称为SLA 3D打印)是增材制造领域最流行、最新兴、最广泛的技术之一。这项技术基本上是在高功率紫外线激光的帮助下工作的，该激光通过在罐内内置平台的基础上添加渐进式层来硬化液体树脂，以创建所需的3D形状。我们的SLA 3D打印机通常由五个主要部分组成，其中包括一个装满光聚合物树脂的水箱，一个内置平台，紫外线led，树莓派和Arduino Uno。我们的打印机采用了3d打印的混合方法，其中修改的LCD用作UV LED和树脂罐之间的屏障，整个想法侧重于创建一个具有成本效益的打印机。LCD屏幕充当塑造3D模型层的模板。来自光源的紫外线以平行的方式直接照射到建筑区域，以便以一层一层的方式创建所需的3D模型。
