波兰3D打印机制造商Zortrax已经推出了新的工程树脂，供公司使用Inksipe UV LCD 3D打印机。
The Zortrax Resin Tough range offers a set of mechanical properties comparable to those of conventional polymers, without sacrificing 3D printability and low shrinkage. Initially available in three colors – white, grey, and clear – Resin Tough is designed for both rapid prototyping and end-use production in a wide range of applications such as research, industrial tooling, and even optical devices.
Zortrax的首席执行官兼联合创始人RafałTomasiak解释说：“ Zortrax Resin Tough Line的引入是使树脂3D打印技术为更具挑战性的生产和工程应用做好准备的下一步。该产品线中的所有可用树脂具有与当今市场上大多数现代笔记本电脑，智能手机，玩具和其他消费产品中使用的塑料相当的机械强度。”
树脂坚硬Grey and White
Resin 3D printing technologies are known for their ability to produce ultra-precise models with quality surface finishes at high speeds. Unfortunately, material strength is an area in which they typically lag behind, with most common resins on the market lacking in the durability department. Resin Tough looks to remedy this.
The first two colors,Grey and White, are most comparable to ABS polymer. The resins offer a Shore D Hardness of 85 and an average flexural modulus of around 1630MPa. Both resins also boast excellent surface features and dimensional precision. With an average tensile strength of around 51MPa, Resin Tough Grey and White are more than suitable for industrial electronics, impact-resistant drone casings, and any other components that require toughness.
作为奖励，白色变体还可以抵抗在长时间暴露于紫外线的情况下泛黄，这往往是相同颜色的聚合物的问题。因此，它可用于3D打印零件，以供扩展室外使用。
树脂坚硬
The third Resin Tough product is characterized by its translucent nature, meaning it is great for printing glass-like components. Much like the other resins in the product family, the清晰的变体is also scratch-resistant, impact-resistant, and delivers an impressive tensile strength of 65MPa.
Designed specifically for customers seeking light-transmitting capabilities, Resin Tough Clear is particularly useful for parts that have to display the insides of an object, or assemblies where visual aesthetics are of importance. Users are given the ability to replace conventional brittle glass with a polymer-based substitute, enabling them to produce more durable end-use product casings, custom lighting elements, and even decorative pieces.
值得注意的是，通过使用后处理技术（例如打磨和清漆），也可以进一步增强3D打印透明零件的光传输特性。
就在上个月，3D打印材料生产商liqcreateadded a new ultra-rigidceramic-reinforced composite resin到其光聚合物投资组合。Liqcreate的最新添加被称为Composite-X，旨在在其工程线上最强，并具有令人印象深刻的弯曲模量超过9000 MPa。
在其他地方，陶瓷3D印刷专家特森3dalso recently launchedthree new UV-curable 3D printing resins。就像Zortrax树脂韧性一样，石墨岩，玉米岩和mullite都是为生产几何复合工程组件而开发的。
