For those who like to drink coffee, for those who need a cup of coffee every day, coffee is a part of their life, even indispensable. Although you can buy a cup of coffee everywhere now, some people still like to make their own cup of coffee. They can choose what they want to add or not to add from coffee beans, but you may have to put up with the noise caused by grinding beans and the time it takes, and even disturb your family.

To this end, Christine Sunu, a 3D printing enthusiast from the United States, specially designed a 3D printing automatic coffee grinder with easy operation and low noise, and it can also be programmed.

This 3D printing automatic coffee grinder consists of motors, wires, grinding heads and 3D printing parts. The powerful motor can achieve slow grinding and effectively reduce noise.

Christine Sunu first removed the parts from the ordinary coffee grinder, then designed the circuit diagram, and then designed the structure and shell of the automatic coffee grinder, in which the bottom was designed with a spiral design, which can be used as a glass jar for coffee beans, and finally printed out the structure and shell in 3D.

Next, Christine Sunu assembled the coffee grinder and developed an APP that allows users to use the phone for manipulation, such as setting timing grinding or even coffee content, to reduce caffeine intake.

After continuous testing, the 3D printing grinder is in good condition with almost no noise. Now, when Christine Sunu is grinding coffee every morning, he no longer has to worry about affecting his family.
