以色列3D打印机制造商巨大3D已经推出了一台新机器，该机器是专门设计的，以减少生产大型复合模具所需的时间。
由公司的铸件（CIM）技术提供动力，Bombosivit 10000使用户能够在快速的四步凝胶分配和铸造过程中创建复杂的工具，从而简化了成型工作流程。为此，系统可以为采用者（尤其是在汽车，航空航天，能源和海洋领域运作的人）解锁较高的吞吐量和减少工具迭代周期。
“We are thrilled to unveil our advanced Cast-In-Motion technology to the composite manufacturing arena,” Massivit 3D CEO Erez Zimerman said at theCAMX 2021博览会。“这个市场渴望创新，这将改变模制范式，以便制造商最终可以加快其交货时间从几周到几天。”
大型凝胶分配打印
Massivit成立于2013年，专门针对工程，学术，建筑和视觉通信市场的客户生产大型机器。该公司的每个系统都是围绕其专有的凝胶分配印刷（GDP）技术构建的，这种方法基本上是FFF和材料喷射之间的交叉，其中凝胶高速挤出并固化成层。
在正常和“专业”迭代中可用，Massivit的旗舰3D打印机，1800系列, is a 145cm x 111cm x 180cm machine that’s capable of creating super-sized models and molds at a pace up to 30 times quicker than traditional technologies. Over the years, this scalability has allowed the systems to address varying applications, including the creation of thermoforming molds and huge advertising displays.
该公司在其1800 3D打印机的成功基础上，选择于2021年4月推出一台新机器：Massivit 5000。该单元旨在满足提供商的需求，该提供商为汽车，海洋和铁路客户生产大型光聚合物零件，该单元具有独特的双材料系统，可在需要的情况下同时使用不同的材料和分辨率的不同材料和水平分辨率同时打印两个零件。
为了支持其不断增长的打印机组合，该公司也发布两种新材料，包括燃烧的dimengel 20-fr以及半透明的设计验证和面向建筑的UL94-V0，并遵循其IPO今年早些时候这看到它筹集了5000万美元，现在它继续扩展其与Massivit 10000的产品。
将“ maskiv”纳入巨大
Launched at the CAMX 2021 expo, the colossal 1.2 x 15 x 1.65-meter 10000 3D printer is built to address what Massivit sees as the pain points of creating large composite parts: cost, lead time and complexity. Largely, the machine is able to combat these thanks to its built-in CIM technology, which condenses a normal 19-step molding workflow into a four-stage process, by eliminating the need for an initial ‘plug.’
In place of a traditional master design, the CIM process begins instead with users creating a desired tooling pattern out of UV-curable gel, which can then be 3D printed from various thermoset engineering materials. Once printed, these parts are immersed in water where their patterned sacrificial material is allowed to break away, leaving a mold that when cured and polished, is end-use ready immediately.
根据Massivit的说法，这种方法产生了“提高的准确性，一致性和更高的可靠性”部分，而比传统上用于创建大型复合构建的工具的浪费少。该公司还表示，巨大的10000比正常零件设计机制要快80％，需要少90％的劳动，这使其成为“改变工具范式”的“破坏性霉菌解决方案”。
“By automating the mold production process, we’re able to offer manufacturers a way to dramatically cut their costs and reduce the associated material waste,” Zimerman added. “The snowballing demand for this digital molding solution is testament to the dire need for this technological milestone, and we are excited to offer it to the CAMX community in the lead up to the Massivit 10000 launch.”
3D打印大小的模具
Outside industrial manufacturing circles, molds may seem like a low-key part of the production process, but their accuracy and durability can be key to the success or failure of their end-products. To improve the speed, scale and sustainability with which these molds can be produced, multiple commercial and academically-funded projects have now been commissioned into 3D printing them instead.

在其他地方，在更实验的层面上，研究人员苏黎世have sought to address similar architectural applications to those of Massivit, by creating a原型金属立面使用3D打印的砂模。“深层外墙”设计由26个单独的碎片组成，高3.5米，最终由大型模制铝制零件制成。
