CASE STUDY: A Sea Change for Sailboat Winches

The story of how Proto Labs helped a French company with a revolutionary sailboat winch design started with a daring adventure at sea.

Pontos, the Saint Malo, France firm that’s reinventing sailboat winches, was co-founded by Michel Chenon and Darryl Spurling in 2010 after, as they describe it, a “hair-raising” close call that brought their sailboat dangerously close to the rocky outcrops of the narrow straits off the island of Brehat, France.

The boat was equipped with a winch for the hoisting and furling of the sails that proved to be too physically challenging for the inexperienced crew to use.

This adventure led the two, along with a research and development team, to spend an intense three years creating and perfecting — with the help of Proto Labs’ rapid manufacturing services — the design of what would become a game-changing new line of sailboat winches. These now award-winning winches would also eventually be used on sailboats that would win or be competitive in several notable yacht races and regattas worldwide.

Honey, I Shrunk the Pyramids: Met Museum, Proto Labs Create Model of Ancient Egypt

For the Metropolitan Museum of Art’s exhibition, “Ancient Egypt Transformed: The Middle Kingdom,” on view at the New York museum through Jan. 24, 2016, exhibit planners decided to reconstruct the pyramid complex of King Senwosret III in both a virtual and physical model.

The scale model of the pyramid site is displayed in the Metropolitan Museum of Art’s galleries.

The physical 1:150-scaled model of the site is based on a 3D virtual model that was produced first, and modeled after 3D-printed prototype parts that were created by Proto Labs. For perspective, the main pyramid of the original complex was more than 206-ft.high. In the scaled model, it is 1.5 feet. The creation of the model, which is intended to bring this important Middle Kingdom era to life for visitors to the exhibition, involved a process that was an intriguing blend of traditional and digital methods. This process included traditional sculpting, model-making, mold-making, casting, carpentry and faux painting, plus digital methods of fabrication, specifically 3D printing. The additive manufacturing process by Proto Labs served as the Met’s prototyping phase that helped replicate the unique parts of the model. Continue reading
