Two-day Virtual Training on 3D Printing and PCB Design under CoE in Robotics and Industrial Automation
The Department of Electronics and Communication Engineering organized a two-day Virtual training on 3D Printing and PCB Design. In this online training, students trained on 3D CAD modelling using 3D printer, CAD design for electronic circuits, and training on PCB prototype machine. This training was conducted by Mr. Bhanuteja G (AP/ECE), on 12th and 13th November 2020, using Microsoft teams Live-event platform. 170 students from various disciplines registered and participated in this training. The training began with an explanation about the importance of CAD modelling, and the difference between model, prototype, and products.
The training was divided into two sessions – in the first session, Mr. Bhanuteja G explained to the trainees the difference between subtractive manufacturing and additive manufacturing, the types of 3D printing, 3D printing materials and applications of 3D models.
Then, he introduced the students to the TINKERCAD online platform, to design 3D model and generate .stl files. The students understood how a 3D model is designed and the significance of converting .stl to .gcode format.
At the end of the session, a model designed by students was 3D printed.
The second session of the training was on designing a PCB for mobile charger circuit. During the morning session, Mr. Bhanuteja G explained to the students about the design of circuit and performing analysis using CAD software. Once the circuit analysis was done, students learnt how to convert a circuit to PCB layout and generate gerber files.
Later, Mr. Bhanuteja explained why gerber files need to be converted to .nc formats. He also listed out the PCB design steps, using Nvis 72 PCB prototype machine.
- Students understood the basics of CAD design for 3D modelling and PCB design.
- They learnt the usage of 3D printer, importance of modelling, PCB design and circuit analysis.
- They got clarity on the difference between subtractive manufacturing and additive manufacturing.
- They learnt about the design rules to be followed for designing any circuit, and how to place components in PCB.
