Comparative study on ultra-thin diamond saw blades made by SLS and FDMS

Additive manufacturing for diamond tools is introduced into ultra-thin diamond saw blades, using the fused deposition molding sintering (FDMS). The application of selective laser sintering (SLS) and the FDMS in manufacturing ultra-thin diamond saw blades are introduced in detail. And they are compared from the perspectives of basic equipment, process principles and steps, materials, costs, and applications in production. The results show that both the processes possess the ability to manufacture diamond ultra-thin slices with strikingly high precision and excellent performance under the condition of selecting suitable materials. SLS is characterized by high energy consumption and cost, simple process and one-time finished manufacturing, suiting for the research and development of ultra-thin diamond saw blades. FDMS process has many complicated links, and each parameter of the link needs to be optimized separately. However, it is convenient for mass production of products with consistent performance.
