The latest webinar in our continuing series of rapid manufacturing presentations focuses on rethinking the traditional medical device development cycle. With new prototyping tools available, product designers are accelerating development since they can iterate and test new designs more effectively.
- Strategies to accelerate medical device development cycle
- Prototyping effectively with rapid manufacturing
- Reducing risk with design analysis
The webinar can be viewed on-demand here.
Technology in the 3D printing space is advancing at the speed of light—everything from support structure software to material options and properties to ever improving processes. Some simply take these advancements as small steps in the overall progress of 3D printing, but these improvements are significant attributes that add value across industries and applications.

Medical and Health Care Development
Industries are adopting this technology for varying applications at very different paces. The health care industry has embraced nearly all forms of printing, but has particularly grasped onto direct metal laser sintering (DMLS). As we discussed last month, DMLS has a solid advantage over other 3D printing processes since it produces functional, production-quality parts from metal powder. When plastics are concerned, selective laser sintering (SLS) is another additive manufacturing process with production in mind.
Product developers, designers and engineers in the medical and health care industries use many different types of 3D printing technologies, but why?
- concept modeling and prototyping during early phases of product and device development
- iterating design often to get parts in hand fast
- reducing financial and design risks
- building high-quality assemblies for end users to evaluate and influence human factor designs
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.

For the sixth consecutive year, Proto Labs has been recognized as a Top Workplace by Workplace Dynamics, a national survey firm that researches participating companies through confidential employee surveys.
The firm looks at individual factors such as employee wages and management, but also aspects that include career potential and a company’s future. The survey is conducted in 50 U.S. markets and local results are compiled by Minneapolis’ Star Tribune.
Welcome to the “Code Cave,” a new collaboration area inside renovated office space at Proto Labs’ Maple Plain, Minn. headquarters.
Our company is one of 110 Minnesota-based employers that scored high enough to qualify as a Top Workplace against Workplace Dynamics’ national benchmark.
On a related note, providing employees with a work environment that supports productivity and nurtures innovation is a key aspect of being a top workplace. Along these lines, the vacated production area on the lower floor of Proto Labs’ headquarters building in Maple Plain was recently renovated and converted into office space. That office area is now home to software engineers, web developers, and other technology-based roles. High-tech conference centers are sprinkled throughout and there’s even a “Code Cave” (see photo). Additionally, we’ve opened a new, larger 3D-printing facility in Cary, N.C.
Though the Workplace Dynamics survey covered only Minnesota employees, Proto Labs globally now includes 1,600 employees in 12 locations in eight countries.
We’ve expanded our selection of liquid silicone rubber (LSR) materials, which have some distinct elastic and optical advantages over certain thermoplastics. In addition to three durometers of general-use Elastosil LSR, and medical- and optical-grade Dow Corning materials, we now have two new durometers of Elastosil and a fuel-resistant flourosilicone material at Proto Labs.
Elastosil LSR is a great general-use material that has good moldability characteristics, a good overall appearance and is transparent until colorant is added. Shore A durometers of 40 and 60 have been added our current offering of 30, 50, and 70 durometers.
- 40 durometer Elastosil has a tensile strength of 10.0 N/mm² with a tear strength of 33 N/mm and an elongation break of 610%.
- 60 durometer Elastosil has a tensile strength of 9.40 N/mm² with a tear strength of 27 N/mm and an elongation break of 340%.
