Cubicure是VAT聚合3D打印机开发人员，成立于维也纳技术大学Tu Wien的旋转公司。为了鼓励在行业中采用更多基于光刻的3D打印技术，Cuticure的创始人开发了一个专有过程，该过程扩大了可用的材料范围vat polymerizationprocess.
Cuticure的热光刻过程与粘性树脂一起工作，使高清塑料物体超过了许多常见的轻反应材料的特性。
Curing challenges
One of the reasons industry has been slow to adopt lithography based 3D printing processes is due to, according to Cubicure, “the poor material properties of the available photopolymers.”
公司网站继续解释,“由于their molecule structure and high crosslinking density, [currently available photopolymers] are brittle and lose their stiffness at elevated temperatures.”
Cubicure’s solution is to 3D print using highly viscous resins, which requires a Hot Lithography process.
Hot Lithography
A patented process, Cubicure’s Hot Lithography consists of a heating and coating mechanism, operating at temperatures up to 120°C.
为了打印粘性材料，必须精确控制温度，不承担任何热峰值，意外聚合或材料降解。
The hot, liquid material is hardened by exposure to a high precision laser-scanner-system, available in light wave lengths ranging between 375 nm (UV) and 405 nm (visible blue).
The resulting products excel in impact strength, toughness and heat deflection compared to those produce in common “cold” lithography processes.
“Our technology offers great benefits for many applications,”explainsDr.Cuticure业务发展主管Markus Pfaffinger。
“我们在汽车，航空航天，电气和电子产品方面也看到了巨大的机会，以及工程，精密工程和整个供应行业的机会。”
The Caligma 200
Cubicure’s Hot Lithography technology is implemented in Cubicure’s Caligma 200 system.
Caligma 200的构建量为200 mm x 100 mm x 300 mm（l x w x h），使“聚合物零件和复合材料的中小型批量的经济生产”。
The beam diameter at focus is tuneable, producing layer heights between 10 and 100µm.
The 3D printer is due to be showcased atHannover Messe, 23 – 27 April 2018.
工业机会
在Tu Wien的其他3D印刷相关项目中，研究人员成功实现了铅笔点精度of a multiphoton lithography process. Aliasghar Ajami’s team at the university is also working toidentify initiator molecules in photopolymers产生基于光刻的3D打印过程。
For Cubicure, the next step is to introduce this technology to more high value industries, such as automotive, aerospace and healthcare. Dr.公司首席执行官罗伯特·格梅内尔（Robert Gmeiner）评论“ 3D打印已经在原型或公用事业模型的生产中起关键作用，”
“但是，即使对于少量生产或必须根据个人客户的个人需求（例如医疗部门的组件）量身定制的所有工业产品，高质量的3D打印提供了绝佳的机会。”
