    Bearings are used to prevent friction between parts during relative movement. In machinery they fall into two primary categories: anti-friction or rolling element bearings and hydrodynamic journal bearings. The primary function of a bearing is to carry load between a rotor and the case with as little wear as possible.

Although 3DP can be considered an indirect ceramic inkjet printing process, its distinctive feature is the use of powder beds, which is why 3DP is classified as a powder-based technique in this review.

  • 3D printing of ceramics: A review - ScienceDirect

    Additive manufacturing (AM), or, in a non-technical context, 3D printing, is a process where physical parts are manufactured using computer-aided design and objects are built on a layer-by-layer basis [ 1 ]. Usually, these procedures are called toolless processes.

  • Dental Burr - an overview | ScienceDirect Topics

    Dental burs have revolutionized the dentistry field and are used for cutting hard tissues such as bone or tooth [1,4,6–9]. They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used.
