AB  - Micro tools/parts are attracting increasing attention due to the miniaturization evolutionary tendency in many fields, whose functionalities are critically determined by their materials and shapes [1- 5]. Sharp-edged ceramic microparticles have great prospects to be used as micromachining tools and micro components. However, it remains a huge challenge to fabricate nontransparent ceramic sharp-edged microparticles in a high-throughput way while taking their shape complexity, precision, and strength into account [6-8]. Herein, we present an online mixing and in-situ polymerization strategy: “one-pot microfluidic fabrication” along with two novel microfluidic device fabrication methods: “groove & tongue” and sliding assembling, succeeding in obtaining both transparent and nontransparent microparticles with great shape diversity, complexity, precision, density and strength. The throughput rate is increased by 2 orders of magnitude higher than other methods. Compression and scratch tests demonstrate the promising potential of the obtained microparticles being of practical use in a wide spectrum of applications, including micromachining, microelectronics, microrobots, microsurgery, etc.
