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
Developing medical devices or health care components? Here’s five good material options to consider.
PEEK, PEI (Ultem) and PPSU (Radel). Attributes: High temperature resistance, creep resistance and works well for applications that require sterilization.
Polycarbonates (Makrolon and LEXAN HP1). Attributes: Good clarity with clear and translucent applications, good impact resistant, and durability.
Medical-grade liquid silicone rubber (QP1-250). Attributes: Thermal, electrical and chemical resistance, biocompatibility, and is suitable for skin contact.
Titanium (Ti 6-4). Attributes: Lightweight, temperature and corrosion resistant 3D printed metal used with direct metal laser sintering (DMLS) process to produce fully functional medical components.
WaterShed XC 11122.
WaterShed XC 11122. Attributes: ABS-like material used to 3D print clear microfluidic parts with sterolithography (SL) process. Resistance to water and humidity, and good for lens and flow-visualization models.

While there are a handful of major players in the medical and health care industries, there are actually more than 6,500 active medical device companies in the United States — most of which are smaller firms with fewer than 50 employees. There is little doubt that, with the combined industry efforts, research and development in the medical device space will continue to innovate and grow for years to come.
What drives innovation at these companies ranges from economic indicators to technology advancements to government regulations. But some of the most interesting factors driving development right now can be found in demographics and consumer behavior.
So, what does is mean? The fluctuation in demographics will translate to an increased demand for devices supporting later life care as the baby boomers enters their 70s. This includes everything from surgical devices to support orthoscopic procedures to at-home glucose measurement equipment. Furthermore, we’ll start to see an upward trend in births as Gen Yers move into their 30s and start families. These factors will start to shape how thousands of medical and health care companies re-imagine existing products and development new ones.
As a result, there is a heightened need to launch products and devices to market quickly. Iterative development of medical components and devices will reply on various rapid manufacturing processes and materials to ensure products have best chance at successful medical submissions and market trials. And because these products need to pass a significant number of functional tests before being approved for the market, prototypes need to be produced as close as possible to the finished product. This will mean using similar, if not identical, engineering-grade materials and manufacturing methods for prototypes as for production parts.
From metal 3D printing of extremely small surgical components to low-volume injection molding of optical silicone, Proto Labs is equipped to help large and small medical companies tackle the impending changes in the American demographic landscape.
