Disclosed is a technology being implemented in an apparatus for depositing multiple layers of a stream of swarf particles. The stream of swarf particles is generated by interfacing a cutting abrasive wheel on a workpiece. The generated stream of swarf particles may be directed towards a cavity of a die. Multiple layers of stream of swarf particles further results in a 3D printed object that takes the shape of the cavity of the die. The apparatus may also be used to coat substrates. Substrates may include but not limited to metal surfaces, polymers, and ceramics.

Technology and process for 3D printing using swarf particles

Disclosed is a technology being implemented in an apparatus for coating a substrate with swarf particles. The apparatus facilitates depositing metal coating onto metal surfaces, polymers, and ceramics. In this apparatus, the grinding process is retrofitted to deposit coatings onto substrates that range from soft (e.g., polymers and aluminium) to hard (e.g., glass-ceramic) materials. The apparatus comprises a sample holder, an infeed, and a grinding wheel. The sample holder holds a substrate to be coated with swarf particles. The infeed holding a work piece. The grinding wheel is mounted at a predefined height over the infeed. The apparatus is used to perform metal coating by depositing the swarf materials on surface of the substrate. It may be noted that the swarf materials are generated by grinding the work piece with the grinding wheel.
