We’re back for another round of trebuchet testing, and this time the prototype is beginning to look like a functioning weapon of (small scale) warfare. Above you can see the prototype assembly. The supports hold …

Wheelchair attachment prototype
Our initial design for the wheelchair attachment would have taken over 40 hours to print at the density we wanted, so we printed a smaller version of the part. The reason we didn’t want …
Filament Detector Setup and Attaching to Printer
At this point in the project, we have the color sensor system ready to be attached to the printer to start detecting the filament. A few things to note are that due to availability of …
Printed Prototypes and Assembly
This week’s blog post will focus on our printed prototypes and the overall beer faucet assembly. Before delving into the results of our printed prototypes, I’d like to recap the three parts that our group …
Insole Optimization Using Cura
Our group was a little delayed on running the 3D printing simulations in the provided Cura software due to difficulties with the 3D scanning of the foot that we experienced. Now that we have a …
Trebuchet #2 – Printing Supports.
Our next step in our trebuchet project is to print actual supports for our arm-counterweight assembly. We generated a very simple design to suit our needs. Up to this point we had only printed parts …
Trebuchet Team 1 picture of the first and latest built trebuchets
Trebuchet Team 1 picture of the first and latest built trebuchets To give you an idea how the changes we made effect the final Trebuchet we want to provide you with pictures of the first …
Trebuchet Design Optimization
Upon completion of our first prototype, it was clear that our components were oversized which led to a long build time of approximately 13 hours. To optimize the design we reduced the number of parts, …
Filament Detector comparison
Throughout our research for methods to detect filament errors, we came across a few concepts worth considering. For our design, we decided to use RGB color sensors to detect color changes on a marked wheel. …
Trebuchet #2 – Build time and Material optimization
After testing we decided on a few changes that could be made for our next iteration of the trebuchet. A couple of changes where made in the structural design in order to reduce build time …
