İSTEK PATENT VE DANIŞMANLIK HİZMETLERİ LİMİTED ŞİRKETİ
摘要：
The present invention relates to binders used in the binder jetting metal additive manufacturing (BJAM). The present invention relates to the use of the resin formed with certain chemicals and used together with the binder consisting of chemicals that regulate the rheological properties such as chemical properties, viscosity and surface tension, which are responsible for binding metal powders in a way such that the sample formed from metal powders does not lose its form.
技术问题语段：
The technical issues addressed in the patent text are related to the binder composition used in the binder jetting additive manufacturing method. The patent text aims to provide a binder composition that can effectively bind metal powders and maintain the shape of the formed sample during the sintering phase. Additionally, the binder composition should have suitable rheological properties, such as viscosity, surface tension, and pH, to ensure effective spraying of the binder on the metal powder using printheads.
技术功效语段：
The technical efficacy of the patent text is that it describes a binder composition for use in the binder jetting additive manufacturing method. The binder composition includes resin, water, ethyl alcohol, polyethylene glycol-300, triethanolamine, and glycerine. The binder composition provides certain technical effects, such as maintaining the shape of the sample formed from metal powders, reducing viscosity and surface tension, increasing viscosity and surface tension, regulating pH, and increasing the boiling point.
权利要求：
CLAIMS
1. A binder composition for the binder jetting additive manufacturing method used to manufacture a three-dimensional product from a material, characterized by comprising; resin, which keeps the sample formed from metal powders without losing its form up to the initial temperature of sintering, water used as carrier fluid and allowing the resin to dissolve, ethyl alcohol which reduces viscosity and surface tension, polyethylene glycol-300 which increases the viscosity and surface tension, triethanolamine, which regulates pH, glycerine which increases the viscosity and surface tension and increases the boiling point.
2. A binder composition for the binder jetting additive manufacturing method according to claim 1, characterized by comprising; water at a rate of 15 to 35% by weight-volume, ethyl alcohol at a rate of 25 to 45% by weight-volume.
3. A binder composition for the binder jetting additive manufacturing method according to any of the preceding claims, characterized by comprising; resin at a rate of 6% to 20% by weight-volume formed by using sucrose, nickel nitrate and similar chemicals.
4. A binder composition for the binder jetting additive manufacturing method according to any of the preceding claims, characterized by comprising; glycerine at a rate of 3 to 35% by weight-volume, which ensures that the processed metal maintains the presence of the resin up to the initial temperature of sintering.
5. A binder composition for the binder jetting additive manufacturing method according to any of the preceding claims, characterized by comprising; polyethylene glycol-300 at a rate of 5 to 35% by weight-volume, which ensures that the processed metal maintains the presence of the resin up to the initial temperature of sintering.
6. A binder composition for the binder jetting additive manufacturing method according to any of the preceding claims, characterized by comprising; triethanolamine at a rate of 0.5% to 3%, which enables the printheads to operate by keeping the pH of the environment at 4 and/or higher values.
