地图集3D, the publisher of cloud-based additive manufacturing tools has released its Sunata print preparation software for Direct Metal Laser Sintering (DMLS) 3D printing. The Sunata software computationally calculates the best orientation and the necessary support structures for metal 3D printing.
Using patent-pending Thermal Circuit Network (TCN) technology, Sunata aims to save users both money and time by improving the simulation process to optimize the additive manufacturing process.
“Design engineering for additive manufacturing is a bunch of trial and error processes by design engineers,” explained CEO Chad Barden. “Atlas 3D is trying to make that “black art” much more science and much less art. We’ve enabled computers to calculate what the best orientation for a part on a build plate is.”
具有起源于设计工程教育的软件
总部位于印第安纳州普利茅斯的Atlas 3D始于2015年的联合项目印第安纳技术与制造公司(ITAMCO),巴黎圣母院, Johnson & Johnson, and theUniversity of Pittsburgh。
该项目，名为“Parametric Design of Functional Support Structures for Metal Alloy Feedstocks,” aimed to create a training software for the next generation of additive manufacturing experts.
经过美国国家高级制造网络的275万美元投资，美国的一部分资金计划以及两年的开发，该软件在印第安纳州高中进行了测试。
学生首先将零件定向在构建板本身上，之后Atlas 3D计算实际的最佳方向（以最小的降温失真为最小的方向），从而允许讲师解释方向的原因。
在最初的成功之后，下一步是创建专业打印准备软件，以平衡最小的失真和减少打印时间和减少。Atlas 3D与Itamco的技术集团一起创建了Sunata。
萨纳塔, the “easy button” for Metal Additive Manufacturing
萨纳塔users directly import their designs as .stl files directly into the cloud-based program (hosted by Amazon Web Services) and automatically receive the optimal orientation and associated support structures.
Sunata使用TCN软件科学地将印刷设计解析为热相似的层，然后使用热建模算法将更大的热相似段分解为较大的热相似段。通过100个不同方向运行设计后，Sunata建议最佳方向和支持结构。
Sunata使用户能够将其要求从最小的失真随着更长的打印时间而扩展到较短的打印时间的边际失真。还提供了所需的烧结材料的总打印时间和数量。
Sunata目前适用于铝(AlSi10Mg)tainless Steel (SS-316L), Stainless Steel (SS-174), Titanium (Ti 6Al-4V) and recently added QuesTek’s new Ferrium C64 metal powder. ITAMCO is currently using these powders and Sunata to 3D print end-use components on an EOS M 290 3D printer.
