Additive Manufacturing (AM) refers to an emerging class of technologies that build 3D objects by the controlled addition of materials in a layer-by-layer fashion, at or near their final shape, with or without complex internal structures, using a minimum amount of machining. Dies and molds, from the numerous thermal gyrations imposed during operation, could have their performance improved by the availability of technologies permitting to maintain a uniform temperature field. AM is becoming an enabling manufacturing technology capable of providing such advantages by the insertion of conformal cooling channels in strategic locations. This integrated thermal management concept will allow a reduction in the duty cycle (increased production rate), an increase in the processing capacity and an improvement of the profitability. However, most of the fundamental concepts in the design and manufacturing of such dies and molds remain to be defined. In that context, this joint NSERC-CQRDA proposal is established to define: (1) optimized methods for design for additive manufacturing (DFAM) of tooling with thermal management systems, (2) how to fabricate such tools and dies with complex cooling channel systems using new high strength/high thermal conductivity powders and (3) how to obtain surfaces with compatible characteristics for the Al forming industry. These fundamental knowledge gaps will be answered during this project. The availability of such high-performance toolings is of key interest to the industrial sponsors of this project, namely Verbom, Exco Engineering, Trumpf and AlTec. All of them will benefit by improving their competitiveness and product portfolio, leading to the ultimate goal of business growth, which will contribute to improving Canada's position in the adoption rate of AM technologies in the tooling and transportation sector.

添加剂制造（AM）是指通过以逐层或接近其最终形状的逐层添加材料来构建3D对象的新兴技术，它们使用最小的加工量，具有或没有复杂的内部结构。 模具和模具来自在操作过程中施加的众多热循环，可以通过允许维持均匀温度场的技术的可用性来提高其性能。 AM正在成为一种能够通过在战略位置插入共形冷却渠道来提供这种优势的能力。这种综合的热管理概念将允许减少占空比（提高生产率），加工能力的提高和提高盈利能力。 但是，这种模具和模具的设计和制造中的大多数基本概念仍有待定义。在这种情况下，建立了该联合的NSERC-CQRDA提案来定义：（1）使用热管理系统的工具设计的设计（DFAM）的优化方法，（2）如何使用新的高强度/高热导电性/（3）为构成构成的特征来制造复杂的冷却通道系统，并使用新的高强度/高热导率/（3）进行表面表面表面表面。这些基本知识差距将在此项目中得到回答。 这种高性能工具的可用性是该项目的工业赞助商的关键兴趣，即Verbom，Exco Engineering，Trumpf和Altec。他们所有人都将通过提高其竞争力和产品组合而受益，从而实现业务增长的最终目标，这将有助于提高加拿大在工具和运输领域的AM技术采用率中的地位。
