When it comes to batteries, 3D printing has several significant advantages compared with conventional battery fabrication technologies: 1) enabling the fabrication of desired complex architectures; 2) precise controlling of the shape and thickness of the electrodes; 3) printing solid-state electrolyte with high structure stability and safer operation; 4) potential for low-cost, environmental friendliness, and ease of operation; and 5) possibility of eliminating the steps of device assembly and packaging via direct integration of batteries and other electronics.
Der 3d-Druck Markt ist halt stark umstritten und es kann schnell von jemand anderem eine andere Methode für ein ähnliches Verfahren erstellt werden.
