Tethon3D, a manufacturer of ceramic powders and photocurable materials has launched its newCastalite投资铸造树脂对于SLA和DLP 3D打印。
Castalite, like other resins, has applications in advanced manufacturing, jewellery and engineering. However, thanks to its physical qualities, it can also be used to 3D print ceramic shell molds for metal casting.
A resin for metal casting
Chemically, Castalite has high heat and thermal shock tolerances, giving it the necessary qualities to cast metals such as bronze, gold, silver, and aluminium.
3D打印的模具需要浇口，门和铸造杯功能正常。如果将这些功能纳入模具设计中，它将准备好接收熔融金属。
一旦使用Castalite树脂打印了3D模具，就必须将其缓慢射击300至1,100华氏度（150至595摄氏度），以使多余的气体逸出并防止其破裂。
使用Castalite直接3D打印模具消除了对传统损失蜡铸件中使用的蜡型的需求。这种材料的减少最终最终降低了金属铸造的成本，并使其更快。
An artistic and technological growth in ceramic 3D printing
Nebraska-based Tethon3D has extensively collaborated withpractitioners who produce ceramic artworks. Itreleased Vitrolite，一种用于SLA印刷的玻璃陶瓷聚合物树脂，2017年。Tethon3d的瓷器材料被提名为2017年3D Printing Industry Awardin the “3 d打印材料f the year” category.
Tethon 3D总裁兼首席执行官Karen Linder对Castalite树脂的受欢迎程度充满信心，理由是“在SLA和DLP硬件中看到的增长”，3D打印也在该产品中研究了这一问题。trends in additive manufacturing for end-use productionseries.
“Recent improvements in 3D printer technology provide higher resolution details in the casted metal part and faster print times,” said Linder.“大多数打印机都可以在25微米打印层上打印，并且在该水平上表现出出色的分辨率。”
