CASE STUDY: Sea Ray Charts New Course with Production Help from Proto Labs

Brunswick Corp.’s Sea Ray luxury boat brand is known for its high-end, opulent yachts that often command seven-figure sales tags. As you might expect, no detail is considered too small, not even something as seemingly mundane as the air-conditioning drainage system on Sea Ray’s L650 Fly model (pictured).

So, when the boat builder redesigned its AC drain-line arrangement, and then extended that new design from the L650 Fly to two other Sea Ray models, the company created a significant supply challenge, which Proto Labs was called on to meet.

The grill was manufactured in a durable, corrosion-resistant ABS plastic at Proto Labs.

“Proto Labs was definitely able to help us more seamlessly go from prototype to production, which is important in our market, to be able to make that transition quickly,” said Randy Hasson, project leader with Brunswick’s recreational boat group in Merritt Island, Florida.

CASE STUDY: Brain-Machine Robotics System May Help Paraplegics Walk Again

Proto Labs is helping researchers at the University of Houston move a science fiction concept to a real-world application that may help paraplegics walk again.

A multidisciplinary research team that includes engineers, neuroscientists, health professionals, and students is working to create, from scratch, a powered wearable robotic device that allows those with lower-limb paralysis from spinal injury, disease, or stroke to regain mobility without a walker or canes.

A sci-fi element lives on in the project, which is taking place at the university’s Laboratory for Noninvasive Brain-Machine Interface Systems. As the lab’s futuristic name suggests, the ultimate goal is to allow users to control the exoskeleton—commanding it to go forward or backward, to turn, sit, or stand—using their thoughts instead of a joystick, switches, or external operator typical of other devices.

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.

CASE STUDY: Robots Do Battle on ABC with Help from Proto Labs

Network television may seem an unlikely source for manufacturing innovation, but don’t say that to the designers of the robots competing in season two of ABC-TV’s BattleBots (a 10-episode run starts Thursday, June 23).

Two competitors in the show turned to Proto Labs recently for prototyping and end-use parts for their warrior robots.

California-based freelance product designer Hal Rucker created The Ringmaster robot, using Proto Labs’ 3D printing for plastic prototypes and production parts, and CNC machining for magnesium end-use parts.

Independent product developer Christian Carlberg, also of California, and his 13-year-old daughter Carissa, designed The Overdrive robot using Proto Labs’ CNC machining to fabricate two sets of parts for Overdrive’s weapon pulley system.

And who ultimately claimed victory in this clash of the robot titans? BattleBot designers were sworn to secrecy, so we’ll just have to tune in to see who won.

Eyeing the Future of Wearable Fitness Tracking

California-based eyewear maker VSP Global is using Proto Labs’ rapid injection molding services to accelerate the design, prototyping and testing phase of a new product, a pair of glasses that includes a health-tracking capability.

The glasses have a fitness tracker built in, a prototype design concept that VSP Global calls Project Genesis. A vision care company, VSP Global includes an eyewear manufacturing and design division, plus a vision insurance plan that encompasses more than 80 million members and a network of 34,000 eye doctors in the United States, Canada, United Kingdom, Ireland and Australia.

Wearable technology is a hot trend right now, and, as VSP Global explained in a recent press release, though “some [wearables] could be considered hype, some…could be considered the start of a personalized medicine revolution.” Continue reading
