6 Medtech Trends to Watch in 2017

THE SHORT LIST

From a predicted slow but steady revenue-growth outlook, and a rising Asian market for the medtech industry, to multi-functional devices and wearables, medical device manufacturers will be watching several trends this year.

Slow but Steady
The $390 billion-plus medical device market will experience growth in 2017, but slower growth than previously expected, reports Kalorama Information, which publishes health care-related market research. Its industry forecast predicts a 2.8 percent average growth over the next five years. “While the user base for medical devices is growing, cost-cutting mechanisms have impacted price increases.”

United States Still the Focus, with Asia Rising
Kalorama also reports that, though most revenues from medical devices will still be earned in the United States this year, China and the rest of Southeast Asia will see far greater growth than the overall market in 2017.

Companies Still Seek Innovation
A challenging market has only encouraged the industry to keep funding research, says Kalorama, which estimates that medical device companies spend an average of 7 percent of revenue on R&D, which is higher than most industries.

More Multi-Functional Devices
More medtech manufacturers are making multi-functional devices that can be used for a range of applications, according to Qmed.com. Devices that are specialized are falling out of favor at hospitals because of the premium put on floor space. An example Qmed cited is the Scout device (pictured), from Silicon Valley-based Scanadu. The device can measure pulse oximetry, temperature, heart rate, ECG, and other variables.

3 Ways to Improve Operations with On-Demand Production

On-demand production of parts not only accelerates time to market, but reduces total cost of ownership since it eliminates the large capital expenses of traditional injection molding. Here are three ways on-demand production reduces your design risk, accelerates your product’s time to market, and saves you money along the way.

1. Bridge Tooling
Once you’ve finalized your product design, there’s often a gap between the end of product development and production. Leveraging rapid injection molding with cost effective, aluminum tooling can help you get to revenue more quickly while you wait for your production manufacturer to finalize steel tooling.

2. Supply Chain Emergencies
On-demand manufacturing provides a reliable alternative if global shipping delays or other disruptions in your supply chain arise—minimizing any potential loss of revenue. Further, products with high demand volatility can be more easily managed with on-demand manufacturing.

3. Low-Volume Production Runs
Before committing to large-volume production runs, validate your product design with low-volumes. Pilot runs can aid in testing assembly processes or gauging market demand. And, on-demand production is an economically viable solution for products with relatively low sales volumes—typically in the few thousands or hundreds of units.

How to Design 4 Common Metal 3D Printing Features

Click to watch an on-demand webinar on how to design for direct metal laser sintering (DMLS).

Direct metal laser sintering (DMLS) is not intended to replace traditional metal manufacturing like casting, metal injection molding, or machining. Rather, it’s a product development tool that opens up new design possibilities. Product designers and engineers commonly rely on metal 3D printing to manufacture complex geometries, reduce the number of components in an assembly, or even lightweight objects.

Here’s a look at how to design 4 common features found in metal 3D-printed parts.

1. Self-Supporting Angles
A self-supporting angle describes the feature’s angle relative to the build plate. The lower the angle, the less the likely it is to support itself.

Support angles built with direct metal laser sintering

Designing support angles no less than 45 degrees will ensure a quality surface finish and detail.

Each material will perform slightly different, but the general rule of thumb is to avoid designing a self-supporting feature that is less than 45 degrees. This tip will serve you well across all available materials. As you can see in the picture above, as the angle decreases, the part’s surface finish becomes rougher and eventually the part will fail if the angle is reduced too far. Continue reading

THE SHORT LIST: See You at Trade Shows This Fall

Look for the Proto Labs booth at various trade shows this fall. Here’s a brief roundup of where you’ll find us:

SEPTEMBER SHOWS

IMTS-Chicago-Sept. 12-17

The International Manufacturing Technology Show at Chicago’s McCormick Place is the largest manufacturing show in the Americas and will feature more than 2,000 exhibiting companies and over 114,000 registrants. Visit us at booth N-72 throughout the week. Proto Labs staffers are also presenting at the conference:

  • Jonathan Bissmeyer, Senior Quality Engineer: “Designing for the DMLS Process,” 1:15 p.m., Monday, Sept. 12, Room W192-B.

THE SHORT LIST: 4 Ways to Leverage Rapid Overmolding

Rapid Overmolding is the latest addition to our injection molding service. Now, you have a fast way to create injection-molded parts with two different materials. We use a pick ‘n place method.

That means we follow a two-step process. First we mold the substrate part. Then we place the substrate part into the mold and a second material is injected to form the final, two-material part.

Here are a few benefits of rapid overmolding.

Vibration dampening: Dampen vibration by adding liquid silicone rubber to parts made of hard plastic, like ABS, or if it’s a handhold device (think toothbrush), it can even be used to improve grip.

Fast, flexible volumes: Often, manufacturers will not process low-volume overmolding orders, but now you have the ability to manufacture 25 to 10,000+ overmolded parts within just a few weeks.

Simplify multi-part assemblies: Reduce cost and save time spent assembling parts by combining two materials in one molded part.
