New 3D printing technique creates unique objects quickly and with less waste

MIT and Delft University researchers developed a new 3D printing technique called speed-modulated ironing. This method uses heat-responsive materials and dual nozzles to create objects with multiple colors, shades, and textures in one step, improving efficiency and precision over traditional multimaterial 3D printing. The technique controls nozzle speed to achieve specific material responses, enabling custom designs without hardware modifications.
