Senior Design I Presentation – UTD

Hello All,

At the end of our senior design semester 1 project we presented our project on May 1st, 2015  to corporate members, faculty and our peers. Here is a glimpse of our poster that was used for presentation purposes. Stay tuned to see our progress in Senior Design II which begins May 27th. We are currently working on the software part of the project to control the multiple extruders. We look forward to update you regarding our progress..

Dual Extruder Design

We just wanted to provide an update regarding the Dual Extruder that was built using a 3D printer for the purpose of our project to be able to print dual thermoplastic materials,

Update on Team XTRUDER

Hello Everyone,

We just wanted to provide an update on team XTRUDER regarding their progress on the project. Here is a short video where they have printed some copper traces and mounted some LED’s on them. The MSP430 Launchpad uses the Blink program to test the circuit out. Stay tuned for more updates.

Boosterpack Testing

Hello Again Everyone,

We just wanted to provide you a short glimpse into our testing process for the new boosterpack with a single extruder for the time being. Stay tuned for more updates..

3D Printer Boosterpack

Hello All,

We would like to showcase our first part of the project which was developing the boosterpack to control the 3D Printer.

The objective of this part of the project is to design and build the boosterpack to be able to control 6 stepper motors to be able to move in the Cartesian axes as well as drive the dual extruders and paste extruder.

For this part of the project we used Eagle CadSoft 7.2 to design the board and route all the connections properly. We were able to reduce the complexity of the existing boosterpack by replacing the drivers with Palolu drivers which performed the same function.  Once the design was created, we sent the schematics to Oshpark for the board to be manufactured. Once the board was delivered all the parts were soldered onto it manually and tested for functionality which was a success!!

For this part of the project, the most crucial part was getting used to the Eagle Cad software. Since this was our first exposure to using the software, it was a learning experience for all of us. Several online tutorials were used to help us in our research in building the best possible design for our board. This included learning about the appropriate route thickness, current calculation needed to drive the motors and make the board running without any obstacles.

Posted below is the actual board after soldering the components and the Eagle schematic of the board we sent to OshPark.

Welcome to CIRC3D Blog…

Hello Everyone,

We are a team of five electrical engineers working along side Texas Instruments for our senior design project. This blog will bring you behind the scenes look into the circuit board printer by the engineers who developed it. We initially started the project early March of 2015.

The goal of this project is to be able to print a simple circuit board using an existing model of the Pruisa i3V 3D printer which is available at Makerfarm. The project was divided into two teams: Team CIRC3D and Team XTRUDER. CIRC3D comprised of five electrical engineering seniors at University of Texas at Dallas. Team CIRC3D was assigned the tasks of developing the boosterpack with additional functionality as well as developing the dual extruder capable of extruding dual materials.

Currently, the hardware portion of the project has been completed at the end of the first semester and further details will be posted soon. Please stay tuned. We look forward to sharing some exciting developments with you..
