Introduction
As a professional CNC machining service provider, we are always paying attention to changes and updates in new technologies, because this means that if we can introduce the best technology, we can provide better technical support for your design projects. But traditional news columns only have one article. On the one hand, the information is shorter, and more importantly, it takes time to find similar news.
To allow our customers to get the latest 3D printing news quickly, we have collected the latest 3D technology trends from the latest channels.
News highlights
Recently, a technical paper on 3D printing published in 《Nature Communications》 caused quite a stir in the academic community. A team of researchers led by the University of Cambridge has invented a new technology that uses high-energy lasers to fine-tune the properties of 3D-printed metals without affecting the complex shapes they form.
Numerous facts have proven that additive manufacturing or 3D printing prototyping technology has been a popular manufacturing tool since its inception, but it also has some inevitable shortcomings, namely, since materials and geometries are formed simultaneously during the additive manufacturing process, Therefore, it is not possible to further process the solid to drive controlled microstructural changes without inevitably compromising the complex shape of the part.
Therefore, some new methods need to be introduced to overcome these problems. A Cambridge research team from Singapore, Switzerland, Finland, and Australia proposes using laser powder bed fusion (LPBF) technology to fine-tune metal properties.
The process works by using a laser to selectively melt staggered spots on a complete object made of stainless steel, thereby changing the structure of the crystal. It’s similar to “heat and slam” in a large area, but it uses lasers to deal with the brittleness printed metals tend to exhibit. You can think of it as selective reheating on a small scale, turning the laser into a tiny hammer.
Dr. Matteo Seita, Department of Engineering at the University of Cambridge and team leader, said: “The proposed method can control the final properties of metal objects to a large extent. Furthermore, it can help reduce the cost of metal 3D printing, “thereby improving the metal manufacturing industry. Sustainability. Perhaps shortly, combining lasers with cryogenic processing techniques will reduce the steps required to 3D print parts for engineering applications. ”
