立方, an Austria-based manufacturer of polymer 3D printers, has showcased its latest additive manufacturing system atFormnext 2021.
The newCerionproduction plant是基于公司专有的大型树脂3D打印机Hot Lithography process. Intended to ‘scale up’ lithography-based 3D printing, the machine sports a build volume measuring 1000 x 280 x 300mm and is capable of printing entire layers in under 90 seconds, regardless of the number of components in the build.
Cuticure已将其最新系统用于工业市场，并在汽车，电子，医疗技术，工具，最终使用批量生产以及大型零件的功能原型中应用。在几年的研究和开发的支持下，许多飞行员客户已经在使用Cerion。
“This is the essential breakthrough in the industrial upscaling of lithographic printing processes,” explains Dr. Robert Gmeiner, Managing Director and CTO of Cubicure. “In this printing process, both the material intake and the detaching of printed polymer layers from the carrier film are scalable.”
Hot Lithography 3D printing with Cubicure
Founded in Vienna in 2015, Cubicure set out with the aim of combining impact strength, heat deflection properties, and excellent surface qualities in 3D printed polymer parts. The firm quickly found that theresin materials required for this would have to be highly viscous在室温下，但标准的基于SLA的3D打印过程无法处理此类树脂。
为了解决这个问题，立方体开始开发自己的加热的3D打印过程，专门用于固化高粘性，高性能的化学物质。如今呈现的热光刻技术依赖于一种特殊的加热和涂料机制，使其能够在高达120°C的温度下安全地处理高粘液树脂和糊状物。由此产生的印刷零件可以是特别坚韧和耐温温度.
Hot Lithography first made an appearance in the company’sCaligma 3D打印机, a small series production engine with a build volume of 200 x 100 x 285mm.
Cerion 3D打印机
To tackle the large-format marketspace, Cubicure had to depart from the concept of resin vats altogether and designed an entirely new configuration for the Cerion. The latest system now features a mobile printing head and a revolving resin carrier film – innovations designed to facilitate scalable lithographic 3D printing.
With the new setup, the entire 1000 x 300mm build area delivers an optical pixel accuracy of 50 x 50 microns. Thanks to the traversing printing head and precision exposure control, there is reportedly no variance in manufacturing precision between different areas of the print chamber, meaning every part is a batch production build should be completely identical. With Cubicure’s new system, the Hot Lithography process also takes place at 100°C, meaning users will be able to leverage the firm’s entire tried-and-tested photopolymer materials portfolio.
Gmeiner补充说：“建筑过程的许多因素（例如工艺力）现在与部分几何形状和建筑平台占用率分离。即使是打印平台的宽度和长度也不再对过程性能产生影响。经过三十年的立体光刻，最后发现了一个可扩展的过程。”
