Luckily for 3D printing enthusiasts of late, the Daft Punk duo graduated from wearing trash bags on their heads quite some time ago. These French Grammy winning musicians have made themselves known not only by their now ubiquitous dance tunes but also by their futuristic head gear, which lately seems to be quite inspiring at the 3D printer.
Meant not only just to hide their faces so that they aren’t constantly barraged by fans, the French duo, made up of Thomas Bangalter and Guy-Manuel de Homem-Christo, also employ the helmets and overall robot costumes as a somewhat philosophical way to mix fictional and real personas.
Now, taking a look at the Daft Punk helmets and the reality of how difficult they might be to fabricate, the Design, Fabrication and Testing research team at SAIT Polytechnic tried their hand at reverse engineering the headpiece worn by Guy-Manuel. Giving cred to the Daft Punk design team–they found that this certainly was no easy feat–over a two-month stretch.
While producing pop star paraphernalia was certainly part of the end goal, this project was meant to enhance the team’s skill set in terms of 3D printing, rapid prototyping, and surface modeling. And that it did. They had to be very resourceful just to get the correct initial design going, duly challenged from square one.
“The helmet was difficult to model. When we reverse engineer something, we usually have a physical part to work from. Since we didn’t have a helmet, we looked on the Internet for high-resolution pictures and videos,” explained researcher Emerson Burns. “We imported the best front and side photos into SOLIDWORKS and built our model from there, referencing other photos for accuracy. Once complete, we broke the model into pieces for 3D printing.”
If you compare the visors between Thomas Bangalter and Guy-Manuel, you will see that the team definitely chose the more difficult visor to create, as it encompasses so much more of the helmet with open space. The design team was forced to get extra creative in that area too in terms of other materials, as they were using ABS for the 3D printing mold. The visor, however, had to be vacuumed formed, which meant they needed to heat, stretch, and use a vacuum on the plastic.
“We initially wanted to use 2-mm Polycarbonate, but the forming temperatures were too high. We ended up using 1.5-mm PETG (pop bottle) plastic. It still had to be heated to 135 degrees celsius, more than three times the maximum recommended working temperature of the ABS plastic. If the buck heats above 60 degrees it will start to warp,” explained Burns. “After about six seconds we were in the 60-degree celsius range which prevented warping.”
“We are now capable of printing tools to manufacture parts that can’t be 3D printed,” said Burns. “Industry clients often ask us to improve on products they already have. This involves taking the product apart, 3D scanning it, rebuilding the product using computer aided design, altering the desired parts and then 3D printing each element for testing.”
This project certainly came from a different angle as compared to another helmet our own Scott Grunewald recently covered from the popular Adafruit team. Known for incredible 3D printing savvy and the ability to jazz up even the most basic of items and gadgets, the Ruiz brothers also chose Guy-Manuel’s helmet with the goal of taking it above and beyond its current state, making it more wearable and adding extra bling with complex, programmable LEDs.
While the folks over at Adafruit may be 3D printing rockstars, we’re counting on teams like those at SAIT Polytechnic and their Applied Research and Innovation Services (ARIS), which works to take on projects uniting the needs of industry with the knowledge and skills of faculty and students to bring innovations closer to market.
