3D Printing Experts Discuss Technology’s Future

3D printing is the topic of conversation in our latest Journal issue, which focuses on the technology’s next dimension—how additive manufacturing is poised to make a giant leap forward in capabilities.3D printing

The cover story includes interviews with three leaders from the 3D printing industry who offer insight on a variety of topics, such as advancements in new machines and materials, a growing demand for 3D printing for production parts, and notable trends in software.

Another feature, “A Cloud-Based Future for CAD,” explores how 3D CAD design software is increasingly moving to cloud-based models, a trend with benefits for both product developers and manufacturers.

Elsewhere in the Journal, our Eye on Innovation column features a driverless bus, a 3D GoPro, and a DIY Bluetooth.

DFM Analysis, Injection Molding Help Spring Company Reduce Costs

An Illinois-based steel-spring manufacturer recently called on Proto Labs to help reduce component count and save time and money on a device the company uses to market its services to the aerospace, automotive, oil and gas, and medical industries.

Smalley has long equipped its sales force with a small demo device, a handheld “comparator” that shows the relative size and performance of a wave spring—which Smalley manufactures—compared with a coil spring.

The company turned to Proto Labs for help with solving a cost issue when Smalley considered redesigning the comparator to “use them as ‘giveaways’ to prospective customers,” explained Lane Persky, Smalley marketing manager. “We were looking to go from about 20 of the original comparators, which each cost about $100 to produce, to an initial run of 1,000 redesigned comparators at a target cost of about $15 each.”

Proto Labs’ design for manufacturability (DFM) analysis, and its injection molding service, helped Smalley designers create a new comparator, which would require just seven parts. The original comparators each consisted of 23 parts.

“We chose Proto Labs for the company’s reputation and ability to do both advanced 3D printing for prototyping and affordable, rapid injection molding” for low-volume production, said Persky.


IMTS Showcases Manufacturing’s Diverse Landscape

Amar Hanspal, attending his first ever International Manufacturing Technology Show (IMTS) at Chicago’s McCormick Place this week, tweeted that the event “is a digital manufacturing Disneyland.”

And really, it’s hard to argue with that assessment, based on the sheer numbers of attendees (more than 100,000 over the week-long event), exhibitors (over 2,000 companies), seminars, and innovative ideas being featured.

Tony Holtz, left, technical specialist for Proto Labs, discusses rapid overmolding at the International Manufacturing Technology Show Thursday in Chicago.

A stunning variety of participants are visiting the show: Company presidents, chief technology officers, engineers, designers, software developers, entrepreneurs, and college and high school students. This variety showed in the diverse wardrobe: Those in jackets and ties walked the same exhibit halls as those in flip-flops and shorts.

Rahm Emanuel, Chicago’s mayor, showed up to tour the Association for Manufacturing Technology’s Emerging Technology Center, which featured research and development projects from the Oak Ridge National Laboratory. Those projects included a 3D-printed SUV and the “additive bionic human,” showing additive manufactured medical implants and body parts.

Various special focus areas showcased 3D printing/additive manufacturing, machining, controls and CAD/CAM, fabricating and lasers, and more.

At the Proto Labs booth, staffers answered an array of questions, including queries about our new rapid overmolding service, the trend of using 3D printing for production parts, and the finer points of five-axis machining, another new Proto Labs service.

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.


WEBINAR: Accelerate Design Validation with Proto Labs, Autodesk

There’s still time to register for the webinar, “Accelerating Design Validation with Instant DFM and Pricing Feedback,” set for 3 p.m. Thursday, Aug. 25. Jointly hosted by CAD software maker Autodesk, and Proto Labs, this free webinar shows you how to:

  • Reduce design risks with design for manufacturability (DFM) feedback
  • Slash weeks or months off your prototyping phase
  • Validate your designs early and often with DFM analysis and pricing feedback
  • Use a seamless system of CAD software and online quoting

Autodesk’s Fusion 360 CAD software has Proto Labs’ instant online quoting feature with DFM analysis integrated into its application. This session teaches you how these capabilities work together.
