Canon had 12 patents in 3D printing during Q2 2024. Canon Inc has developed a method for manufacturing a material layer by arranging first particles in a pattern on a base material and arranging second particles in regions where the first particles are not arranged. This method involves rubbing bearing materials carrying the second particles against the base material. Additionally, Canon Inc has patented a method for manufacturing an article containing silicon carbide as the main component by irradiating raw material powder with a laser beam to decompose the silicon carbide into silicon and carbon, turning them into melt.

Application: Method for manufacturing material layer, method for manufacturing three-dimensional object, material-layer-forming apparatus, and additive manufacturing system (Patent ID: US20240157438A1)
The patent filed by Canon Inc. describes a method for manufacturing a material layer by arranging first particles in a pattern on a base material and then arranging second particles in regions where the first particles are not present. The second particles are rubbed against the base material using bearing materials. The claims detail an electrode sheet for a secondary battery, comprising active material particles, a base sheet with a resin base film and a holding layer, and the use of different adhesives in the holding layer. The method involves providing an adhesive layer on the resin base film, adding active material particles, and decreasing the adhesibility of the adhesive layer through various means like elapsed time, heat curing, or UV curing.
The electrode sheet includes active material particles with a higher thermal decomposition temperature than the base sheet, and the resin base film can include materials like polyethylene or polypropylene. The method also involves heating the laminated structure in an atmosphere containing an oxide gas. Additionally, the electrode sheet may contain different compositions of active material particles, solid electrolyte particles, and thermal sacrificial members. The manufacturing method ensures that the resin base film has a lower thermal decomposition temperature than the active material, and the adhesibility of the adhesive layer is reduced to facilitate the manufacturing process. Overall, the patent focuses on innovative techniques for manufacturing material layers and electrode sheets for secondary batteries.
