Week 7

3D Printing

This week I fabricated a 3D object with a 3D printer using filament. The 3D object I design and print is for all staff in the Fablab to port their badge.

Process

  • Steps followed: The design was developed using the Tinkercad software, based on the dimensions of an existing ID card holder. The process began with the modeling of the first component, which incorporates a tab designed to be inserted into the second component. Starting from a cubic base geometry, the dimensions were carefully adjusted to replicate the original object as accurately as possible.

Subsequently, the second component was designed. This stage was considered the most complex, as the piece consists of multiple layers and includes a central aperture that allows the card information to remain visible.

Upon completion of the design, the model was exported in .STL format and imported into the Creality slicing software for print preparation. No support structures were required, as the geometry of the components did not necessitate them. Both components were transferred to a USB flash drive due to limitations in internet connectivity, which made this method more reliable. Finally, the 3D printer was powered on, the filament color was changed, the printer was calibrated, and the print job was configured and executed successfully.

Challenges and solutions One of the greatest challenges for me was editing the piece number two, as it needed to include a space for the identification card as well as the area where piece number one fits perfectly without getting stuck. I conducted several tests to achieve this, until it was finally successful. I also engraved the name Fablab, giving it a personalized touch.

Reflection

  • Key learnings Being persistent and allowing oneself to be guided and supported by an expert to resolve questions, rather than having the task completed by someone else.
  • How it applies to your teaching / context Having a limited amount of time to submit a project and working with new software can often affect a student’s emotions. The greater the level of commitment, the greater the challenge of achieving the objective. Now, as an assistant at the FabLab, I can say that the words used to guide and provide support to students are crucial in helping them feel motivated to achieve their goals, regardless of time constraints, but rather by focusing on the opportunities and resources available.
