3DM Digital Manufacturing, a developer of 3D printers and laser light sources, announced a new technology that can work with specific materials or applications by adjusting their SLS 3D printing lasers.
Compared with carbon dioxide or fiber beam, 3DM's customizable laser is said to produce higher resolution components and enhance mechanical performance in a shorter delivery time. The company has fully optimized its technology in the research and development environment, and is now preparing to launch its own proprietary equipment to market. Once released, these products are expected to promote various 3D printing application cases, in which personalized customization is the key.
The core technology of 3DM Digital Manufacturing is the semiconductor laser specially developed by the company for 3D printing. This enables the company to effectively combine up to six lasers into a single beam to improve beam power and printing speed.
In the first iteration of the product, the company combined four laser printheads and used the splicing algorithm to ensure that there was no gap between the regions. In other words, the company said that its method is scalable, and the introduction of more beams may improve the 3D printing speed. In third-party testing, the technology even produced parts with mechanical properties superior to other leading SLS printers.
In addition, compared with cheaper fiber lasers, 3DM technology can also achieve longer wavelengths without adding materials to ensure laser interaction. It is reported that the company's laser can be emitted at any wavelength in the mid-infrared spectrum, enabling it to match the absorption characteristics of any thermoplastic, and allowing the user to select the most economical raw material for a given use case.
