"C4 Carbides innovative saw blade development program will use Selective Laser Melting (SLM), a metal Additive Manufacturing (AM) technology, to fuse super-abrasive powder to form tooling grade hard materials into net shape 'sharp' cutting teeth, eliminating the needs of post process grinding. UK patents for this concept have been filed.Compared to conventional tungsten carbide tipped (TCT) saw blades, the AM process create high performance cutting teeth for specialist applications tailored to customer specifications. The digital manufacturing process enable C4 meeting challenging design changes and fast respond to customer's requirements. SLM allows material saving of 70-80% and energy and production savings of over 50%, as compared to conventional TCT blade manufacturing.To ensure the success of the AM tooth formation innovation, four key elements are crucial:1. Identifying and developing the use of high performance super-hard materials by SLM.2. New optimised tooth designs for additive manufacturing.3. Process innovation in aligning and precisely forming super-hard teeth on continuous preformed strip.4. Technology scale up for serial production.A new range of cutting tool geometries can be offered, and specific customer requirements for new materials and designs can be made the same day. We aim to transform the linear edge market within 5 years of successful completion of this project."

“C4碳化物创新锯片开发计划将使用选择性激光熔化（SLM），一种金属增材制造（AM）技术，将超级磨料粉末融合在一起，将工具级硬质材料形成净形‘锋利’切割齿，消除后加工研磨的需要。与传统的碳化钨镶齿（TCT）锯片相比，AM工艺可根据客户的具体要求，为特殊应用创造出高性能的切割齿。数字化制造流程使C4能够满足具有挑战性的设计更改，并快速响应客户的要求。与传统的TCT刀片制造相比，SLM可节省70-80%的材料，节省50%以上的能源和生产。为了确保AM齿形成创新的成功，四个关键要素至关重要：1.通过SLM识别和开发高性能超硬材料的使用。2.用于增材制造的新型优化齿设计。3.在连续预成形带材上对准和精确成形超硬齿的工艺创新.可提供一系列新的切削刀具几何形状，并可在同一天完成客户对新材料和设计的具体要求。我们的目标是在该项目成功完成后的5年内改变线性边缘市场。"
