Did you know that the Coca-Cola bottle turns hundred this year? The well-known bottle was invented in 1915, when Coca-Cola set up a challenge for designers to come up with a highly recognizable bottle. Root Glass made the winning design, and based it on the shape of a cacao bean – which by the way isn’t an ingredient of the famous drink. Today an exhibition on the bottle opens in Atlanta’s High Museum of Art. The Coca-Cola Bottle: An American Icon at 100 does not just expose a wide variety of bottles over the years, but also more than 500 3D printed bottles made by Shapeways.
The pieces made by Shapeways are hanging from the ceiling in order to let visitors see the curves of the bottle from a different view. For this art project, the company worked together with Conrad and Partners. They created various versions of the hanging bottles. The main problem with the early versions was that when they were hanging they would stretch out. This resulted in a different kind of shape then the companies intended to create for the bottles.
After three days, they found a new way to create a better 3D printed bottle able to hang and maintain its shape. “In the final design, the bottle is actually printed in a compressed shape to both compensate for stretching and increase packing efficiency in our printers,” writes Shapeways on its blog about the process. “In order to ensure the bottles printed and processed without fail, we designed a cage that would enclose the actual bottle as it printed so that each bottle could be ‘opened’ and revealed individually after being processed.”
All bottles are now to be seen at the museum’s first floor. The exhibition itself will run until October 4th.
