Light and oxygen work together to make 3D printing speed up to 100 times printing small Eiffel Tower in just 6 minutes
Carbon 3D Inc., a Silicon Valley startup in the US, has developed a new “Continuous Liquid Interface Production Process (CLIP)â€, an innovative approach that not only allows the 3D printing process to be 25 to 100 times faster, but also enables manufacturing. A structure that cannot be obtained by other methods. Researchers say that this approach, in addition to opening up new horizons for the medical field, is expected to benefit the automotive and aerospace sectors.
Carbon3D was founded in 2013. The latest CLIP technology is led by the company's CEO, Professor of the Department of Chemistry and Chemical Engineering at North Carolina, Joseph Desimonni, the company's chief technology officer Dr. Alex Hermoskin, and Professor of the Department of Chemistry and Chemical Engineering at Lorena. Edward Samursky developed together.
According to the US news, CLIP technology works by manipulating light and oxygen to fuse objects in a liquid medium to construct a 3D model of the object instead of using a traditional layer-by-layer printing method to create a model of the object. In the experiment, the researchers let the light beam enter the liquid resin through an oxygen-permeable window. The light and oxygen work together to control the curing process of the resin, thus producing an economically usable object. It is 20 microns or less.
Researchers say the process is not only rapid, but also a good control of the structure of the finished product. One of the company's experiments showed that they printed a small Eiffel tower from a large bucket of blue liquid in just six minutes.
Desimonni said: "By rethinking the entire 3D printing technology and the physics and chemistry behind it, we have developed this new technology. The main principle of the new method is to 'make objects in the liquid pool. ', it can manufacture parts faster than traditional technology, and it will also greatly promote the development of materials science and technology."
The research team is currently working on this technology and looking for new materials that are compatible with it. Studies have shown that the CLIP method can make many materials into 3D parts with novel properties, including elastomers, silicones, nylon-like materials, ceramics, and biodegradable materials.
Desimonni further added: "In addition to the many new materials available, the latest method allows us to create objects that are more rugged and have unique geometric structures, such as a heart stent that is customized for a patient. Other methods are not able to obtain such a structure. In the next few years, we may be able to use this method to print patient-specific coronary stents, dental implants or prostheses on demand."
