Benefits of technology
This patented technology allows for better control over how much each type of powders used during three-dimensional printers should have their properties before they start being fed into them. It also includes multiple feeder assembly systems that allow for continuous switching between various types of materials without stopping or slow down production lines. These improvements help create stronger quality printings by producing diverse physical features on the finished product's surface.
Problems solved by technology
This patents discusses three technical challengings related to current methods of creating customized metallurgies with unique features like small sizes, low prices, easy handling, durability over multiple uses (like defense), and ability to produce smaller items at once. Current techniques are expensive and require large boxes containing specific types of raw materials before they become finished goods. There also exist limitations when trying to achieve precise control over the amount of each type of alloy being added into an object through traditional processes involving melting and casting.
