India university students earn cheap 3D printers for 20 days for cash award
internship compilation: Liao Dengfeng review: Cheng Jun autumn
according to the economic times of India in June 15th In Bangalore, southern India, 4 students decided to make use of thick planks, circuit boards, stepper motors, projectors and beaker to make 3D printers. The team was built on mechanical engineering and after 20 days of unremitting efforts, a cheap 3D printer was born.
reported that the 4 members of the team were enrolled in the junior college of mechanical engineering of CMR School of technology, only 20 years old. The 3D printer created for a national exhibition is actually an accident.
they intended to produce biodiesel, but they failed and were 20 days away from the exhibition, and they had no choice but to plan B, but the accident was a great success. The device consumes 43000 rupees (about 4218 yuan), less than 1/4 of the brand 3D printer price on the market.
the result was done under the guidance of Professor Sagar M Baligidad, who envisioned the basic principle of digital light processing (DLP) in a workroom, and finally created the 6 kilogram 3D printer.
the traditional 3D printer relies on the fused deposition modeling (FDM) process. According to the students who participated in the design, the FDM printer was printed with low accuracy and heavy weight. They used ultraviolet light from the projector to print.
they first designed the model in the form of a layer in the computer design software, then each layer was projected into the liquid resin, and the projected resin was cured, and the one layer and one layer reacted. They say this method saves 2/3 of the time compared with traditional printers.
solved the problem of damage to the circuit board and the non reaction of the engine, they lost the other players in the National Championships held in the MVJ Engineering University in April and received cash awards. "They have taken an innovative way to cut costs," said Kumar (Tarun Kumar), a researcher at the
IISc product design and production center. "They can be said to be a change in the game, and the government's financial department should give it support."
the team hopes to continue to improve their 3D printers as a graduation project for their senior year.
