Mr Wu Kam Wa Raymond who is a student of BEng (Hons) in Product Engineering with Marketing, participated in the Challenge Cup, National Competition – Hong Kong Regional Final, Hong Kong University Student Innovation and Entrepreneurship Competition 2017, an open competition organized by Hong Kong New Generation Cultural Association (HKNGCA).  After an intense competition, Raymond was awarded the Third Prize in the Math. & Physics / Mechanics & Control System Section.


Following is about Raymond’s project idea.

With the trends of DIY and the rise in popularity of 3D printing, model making is becoming more popular and people are interested in this topic. Apart from shaping and forming, coloring is also important part of the entire procedure of modeling and prototyping. In such, the modeling color paints are relatively costly consumptions. Makers often use a lot of money to purchase paints but most colors are rarely used, especially in auxiliary colors used as compliments. In order to reduce the cost of coloring and waste, an intelligent paint color mixer was developed. With the color mixer, a maker only has to purchase 5 primary color paints. A large portion of different color paints can be mixed. Wireless Mobile App Control was developed to elevate the convenience. Users can assign the volume and the mixing proportion of each primary color paint to the color mixer by smart device. It will operate automatically to pump the correct volume of each paint to mix the desired color.
