A junior, Bo-han GAO who studying in Department of Mechanical Engineering in Chung Hua University won a gold medal for his work "Improvement of Delta-type 3D Printer from Single-Input to Two-Input". He was glad to say that after taking a 3D printing course in his freshman year, he became interested in the field and researched extracurricular knowledge on the Internet. He found out that duplex nozzle 3D printers are very expensive by chance. At that time, he was thinking that " modified duplex nozzle 3D printer in a low-cost way ". And then  took action to create this work.

Fig/ After Bo-han GAO took a 3D printing course in his freshman year, he became interested in the field. Besides, he researched extracurricular knowledge on the net on his own. He deserves the award.

He pointed out that the work was made of laser cut effect, with D-Force heat dissipation aluminum block and lerdge K control board. That improved the Delta 3D printer from single-input single-output to two-input two-output.

Fig. Bo-han GAO improved the Delta 3D printer from one-in and one-out to two-in-two-out without greatly reducing the printing space and increasing the cost of money.
