Science and Technology Daily, Beijing, October 30 (Reporter Zhang Mengran) Researchers at the University of Cambridge, UK, have developed a multi-functional 3D Printer that can be cracked by people HM, which can print affordable and open design soft materials. This technology will open up further innovation in multiple fields and help create unprecedented designs. The journal Science Report recently reported details of this new affordable printing method.
Printer. HM is a highly customizable 3D printer, comparable to commercial 3D biological printers. It can accept different geometric inputs, including CAD models, coordinates, equations and pictures, to create prints with different characteristics. The development of this multi print head system is based on a mechanical arm and provides multi-function on a platform through heating and ultraviolet modules.
In addition to providing excellent print compatibility with a variety of liquid and soft materials, the printer can perform a variety of operations, including liquid dispensing, multi material printing, variable speed printing, embedded printing (creating free form and drape structures), non planar printing, and so on.
Through the optional heating and ultraviolet modules, the new method can adjust the printability of thermal response and photopolymerization hydrogels, which can be used for a wide range of biomedical applications, including drug delivery, tissue engineering and wound healing.
Researchers use Printer HM created a 2D sketch of the flower pattern, then expanded and transformed it into a 3D flower shape within 4 minutes. Because the control program is completely open and can be cracked, users can reset and expand its functions to achieve unprecedented 3D printing design. The researchers also showed Printer HM has the potential to generate complex tissue anatomical structures. It has successfully created a respiratory system model with lungs and trachea, which is made of alginate ink and printed in the support tank.
Printer. The multifunction of HM, together with its open design and economical features, makes it a reliable choice and sustainable material architecture for future 3D printing innovation using soft biology. The researchers said, Printer HM has the potential to open the door to innovative 3D printing in different fields such as tissue engineering, soft robots, food and environmental materials processing. Its open design, affordability, improved customizability and integrated functions will benefit hands-on researchers and provide viable alternatives to existing commercial printers.

3D printing has been very popular in the past few years, attracting market attention and frequent reports. Today, although its popularity has declined, the pace of technology update iteration has never stopped. Frankly speaking, 3D printing technology does have a lot of room for progress, such as the high cost of equipment and materials, and the high threshold for 3D model design; For another example, it is often used to print hardware materials or devices, while the printing of software materials is relatively rare. These have limited the promotion and application of 3D printing technology to a certain extent. Until now, 3D printing products are still beyond the reach of ordinary people. There is a long way to go for 3D printing to really go deep into industrial applications and even into people's lives. Scientists and engineers are still searching up and down.
