Research and Development in 3D Printing and Delta type 3D Printer. Rebuilt and rewired (replace with thicker copper core wires) a full aluminum large (print surface of 26cm diameter x 30cm height) to obtain better precision and achieve a higher print rate. Upgraded the firmware manually by obtaining the open-source firmware and modify to fit the printer. The printer is capable of auto-calibrate and saves the setting onto the onboard ROM. The final outcome of the project is that it is able to print models in ABS material without needing to use its heated bed, leading to a lot lower power consumption and heat generated to the surrounding.

Note: A Principal Consultant from DreamCatcher (Premier Technical Training Provider) saw the 3D printer that was printing and surprised to see the printer performed so much better than in terms of print quality, speed, and price than the 3D printers that their organization owned.

Obtained MKSBase 1.5 Microcontroller firmware source code and ported it to Anet A8 3D Printer. Porting includes studied the source code and made necessary changes, rewired 3D Printer so the new microcontroller that is not meant for the 3D printer works on it, and tested to ensure that all the features work as expected.
