This example project demonstrates the use of 5 different tools and techniques commonly used and in a fabrication lab. Designed as an intro activity for the rotation of multiple smaller groups of students through different tool stations.
The LED Bracelet is a very simple circuit (LED, power), but uses various materials and tools to make it’s different physical elements.
This example is still in progress, and if you have ideas for how to make it better, please comment bellow!
Ideally the steps in this process can be done in any order (with some slight differences) and at the end of going through all the tool stations, each students has a finished LED bracelet.
Materials & Tools
– LED light
– coin-cell battery
– copper tape
– kapton film
– 3D print filament
– metal snaps
The 5 tools/Techniques:
1) Vinylcut kapton base and copper tape circuit
2) Lasercut bracelet and conductive fabric with fusible interfacing (engrave name or pattern)
3) 3D Print a LED cap light diffuser
4) Solder LED and resistor to copper tape
5) Sew flex pcb to felt bracelet and attach metal snaps
A vinyl cutter (or vinyl plotter) is a computer controlled plotting device with a blade instead of a pen. A vector based design is created in a software program (usually Adobe Illustrator, Corel Draw or Inkscape) and then sent to the cutter where it cuts along the vector paths laid out in the design. The cutter is capable of moving the blade on an X and Y axis over the material, cutting it into any shape imaginable. (taken from >> https://en.wikipedia.org/wiki/Vinyl_cutter)
Laser cutting works by directing the output of a high-power laser most commonly through optics. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials. (taken from >> https://en.wikipedia.org/wiki/Laser_cutting)
3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.

Soldering, is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Soldering differs from welding in that soldering does not involve melting the work pieces. (taken from >> https://en.wikipedia.org/wiki/Soldering)
Sewing is the craft of fastening or attaching objects using stitches made with a needle and thread. Sewing is one of the oldest of the textile arts, arising in the Paleolithic era. For thousands of years, all sewing was done by hand. The invention of the sewing machine in the 19th century and the rise of computerization in the later 20th century led to mass production and export of sewn objects, but hand sewing is still practiced around the world. Fine hand sewing is a characteristic of high-quality tailoring, haute couture fashion, and custom dressmaking, and is pursued by both textile artists and hobbyists as a means of creative expression.
