How Direct Metal Laser Sintering Assists in the Development of Medical Devices

Imagine you’re part of a band of Medieval Crusaders on an expedition in the Near East. Your group must prepare for war against a fully armed and battle-tested army. The only other way to defeat your opponents (aside from having a better war strategy) is to arm your soldiers with superior weapons.
However, creating superior weapons according to exact design specifications would have been challenging due to the limited technical knowledge of Medieval blacksmiths.

The need to create superior products that demonstrate great mechanical integrity is a timeless challenge. In today’s world, there is a growing need to produce devices, parts, and systems for a variety of industries within a short period and a limited budget. The devices used in the medical and dental industries are often geometrically complex and require faithful adherence to design specifications. Fortunately, with innovative new technologies like direct metal laser sintering (DMLS), complex parts can be fabricated quickly and accurately.

Industrial companies like Phoenix DeVentures Inc. engage in medical device development and manufacturing. Their main goal is to design, develop, and manufacture medical parts and devices that benefit both medical practitioners and their patients. By utilizing DMLS technology, additive manufacturers can create superior prototypes that are fashioned from the same materials as the final product. Such components are highly functional and can be subjected to more rigorous testing.

Direct metal laser sintering was developed by EOS, a company based in Munich, Germany. DMLS utilizes 3D CAD models to create .stl files which are then sent to the DMLS machine’s software. Data derived from 3D CAD models—together with energy from directed lasers—is used to build components layer by layer. The technology is so intricate that layers can be 20 micrometres thick.

DMLS technology produces components that would be impossible to produce using traditional manufacturing methods. Medical devices and tools are needed to diagnose, prevent, and treat various diseases. By commissioning reputable medical device manufacturers to create these devices and tools, medical practitioners can provide quality health care to their patients.

DMLS technology facilitates the production of medical devices and tools such as surgical instruments and medical implants that can be used in orthopedic surgery, for example. DMLS technology also facilitates the manufacture of injection mold inserts. By outsourcing prototyping and manufacturing, medical practitioners don’t have to invest in expensive production equipment, facilities, and research to create the final products.
