The dental industry has jumped on the additive manufacturing bandwagon to produce dentures and other devices. Photo courtesy Renishaw pl. Additive manufacturing is the hottest thing to hit the medical device industry since the first pacemaker was implanted in a patient 60 years ago.
The technology has transformed the way that engineers design numerous products. Medical device manufacturers are using 3D printing to create products that were previously impossible to make.
Other products can be personalized to a specific patient or treatment. Engineers can create parts from plastic, metal, ceramics, silicone and other materials. It allows companies to more easily manufacture complex shapes and structures that have typically been difficult to make with traditional plastic-injection molding or machining methods.
Plastic printed part are usually made using ultraviolet, infrared or visible light in conjunction with laser or heat energy. Metal parts are produced with laser-based or electron beam-based printers that use metal powders for raw material; the laser or electron beam fuses together the powder. In the medical device industry, 3D printing enables manufacturers to create customized products that cater to individual patient needs. Engineers are using the technology to produce a wide variety of products, including fixtures, guides, hearing aids, prosthetics, surgical tools, orthopedic implants and anatomical models for pre-surgery applications.
The dental industry has also jumped on the additive manufacturing bandwagon. In fact, demand for applications ranging from dentures to orthodontic aligners is expected to skyrocket over the next decade.
In addition, 3D printing has spawned a new trend called point-of-care manufacturing. Many large hospitals and medical centers are implementing additive manufacturing labs that can create a variety of products in house, such as surgical tools, experimental heart valves and bone implants for use in clinical studies.
Some surgeons have already saved infants born with life-threatening breathing conditions by creating patient-matched 3D-printed splints. The devices expand and degrade as the babies grow.
It operates 23 facilities around the world that assemble a wide variety of medical devices, such as epinephrine autoinjectors, inhalers, kidney dialysis machines and scanners. The second is related to fabrication of surgical tools using near net stainless steel components.
Increasingly, medical device manufacturers are taking advantage of the time and cost savings of additive manufacturing to 3D-print a variety of conventional parts, such as levers and brackets, which are needed for a variety of applications.
Another growing trend is the use of 3D printing to produce low-volume, complex parts for medical devices. Nypro recently redesigned a medical display holder for a blood analysis laboratory instrument. By using additive manufacturing, engineers were able to consolidate 36 parts into six parts. The company operates a 3D Printing Center of Excellence that specializes in developing new ways to produce devices such as customized surgical tools and knee implants.
In the past, when people had their knees replaced, doctors typically had an option of five or six implants of different sizes, and a set of surgical instruments to go with them. Finding a perfect match could be challenging, resulting in longer surgeries and recoveries. Additive manufacturing can also speed up the production of tools. It can really shrink down the process, and make it a lot faster and less expensive to manufacture. Onukuri and his colleagues are also working on printing tissues that can replace or augment damaged organs.
They need to look at the problem from a new point of view. Additive manufacturing got a shot in the arm recently when the U. That should pave the way for more production-ready printed parts. However, for more widespread use in scenarios outside of these somewhat rare cases, the regulatory pathway is more difficult.
Many industry observers believe the FDA action will usher in a new era of printed medical devices and encourage more companies to invest in the technology. In December , the agency issued a comprehensive technical framework to advise manufacturers creating medical products on 3D printers. The new FDA guidance aims to help advise medical device manufacturers on technical aspects of additive manufacturing, such as clarifying what the FDA recommends manufacturers include on submissions for 3D-printed medical devices.
It includes advice on various approaches to 3D printing, such as device design, testing of products for function and durability, and quality system requirements. Many different additive manufacturing processes exist and new materials are continually being developed for medical applications. Each option has pros and cons that engineers must carefully consider.
Several additive printing methods can be used. Popular options include electron beam melting, fused deposition modeling FDM and stereolithography. There are also powder-bed systems, such as direct metal laser sintering and selective laser melting. And, there are powder-fed systems, such as directed energy deposition and laser metal deposition.
Each 3D printing technology is compatible with a different class of materials, which will have differing temperature resistance, tensile strength, elongation at break and chemical resistance.
Medical device engineers need to match their application to their material, resolution and other requirements, and choose a technology accordingly. A wide variety of printers can be used with different types of raw materials to produce parts and subassemblies made out of plastics such as ABS or nylon, and metals such as cobalt chrome or titanium.
However, different processes and materials are limited in terms of print quality and how large of a part they can build. Multimaterial printers, such as the Stratasys Connex3 Objet, allow materials of different properties to be combined easily, greatly enhancing the ability to make more complex and functional devices. Traditionally, plastic has been the most common raw material used for 3D printing, because of cost and versatility.
Suppliers are developing new materials to meet varying requirements for structural, cosmetic and reliability performance. There are also a lot of models printed in plain old powdered polyamide When it comes to anything interacting inside the human body, such as knee implants, titanium is king.
Plastics are rarely used. These are ideal for load-bearing joints or maxillofacial replacement bones. Tantalum is also being used in some implant applications, as are titanium-niobium alloys. Tantalum appeals to medical device engineers, because of its great strength and superior biocompatibility vs. For extracorporeal applications, foreign body reactions must also be considered, as some individuals react to certain metals when they are in prolonged contact with their skin. Printing with metal is different than printing with plastic.
For instance, processing parameters, such as time and temperature are different. Since plastic has a lower melting point than most metals, temperature and power requirements are lower. That can result in lower operating costs over time. According to Frank Medina, technology leader for additive manufacturing at EWI, there are three key differences between printing metal and plastic parts:.
Metal Mania The newest trend in medical device additive manufacturing is metal printing. According to Frank Medina, technology leader for additive manufacturing at EWI, there are three key differences between printing metal and plastic parts: Material properties. Metal properties are much higher than plastic properties and must meet casting and forging standards.
Plastic machines are generally faster than metal systems. Plastics require less energy and can be done in thicker layers. Machine cost and cost per build hour is more expensive for metals, because the systems and materials are more expensive. Airbus harnesses automation to boost fuselage production.

Manufacturing a Quality Medical Device
When it comes to medical device manufacturing, two things are paramount: efficiency and quality. Efficiency is critical as device makers are racing to bring to new products to market as quickly as possible. Quality is critical because no medical device can be marketed that is not fully compliant and approved by the FDA as safe and effective. This is especially true for complex Class III medical devices, which face some of the most stringent quality requirements in the industry.
Mistake-Proofing Production for Medical Device Manufacturing
Medical device design , as the name suggests, refers to the design of medical devices. Due to the large amount of regulations in the industry, the design of medical devices presents significant challenges from both engineering and legal perspectives. These companies are primarily small-scale operations with fewer than 50 employees. Washington, Wisconsin, and Texas also have high employment levels in the medical device industry. Medical devices are defined by the US Food and Drug Administration FDA as any object or component used in diagnosis, treatment, prevention, or cure of medical conditions or diseases, or affects body structure or function through means other than chemical or metabolic reaction in humans or animals. Because of the wide variety of equipment classified as medical devices, the FDA has no single standard to which a specific device must be manufactured; instead they have created an encompassing guide that all manufacturers must follow.

Я могу добраться до Диаспара быстрее, чем пересечь Лис. Другие люди приходили сюда, и некоторые из них тоже говорили друзьям, куда они отправляются.
Однако друзья позабыли их, и они исчезли из истории Диаспара. Со стороны Элвина было бы глупо не принять во внимание эту вполне очевидную возможность. Интересно, сколько раз за миллионы лет, прошедшие со времени разделения двух цивилизаций, люди из Лиса проникали в Диаспар, чтобы сохранить их ревниво оберегаемый секрет. И насколько велика была умственная мощь, которой обладали и которую без колебания использовали эти странные люди. Безопасно ли было вообще строить какие-либо планы.

И причина этого могла бы показаться последнему обидной. В Диаспаре физическое совершенство было столь всеобщим, что личная красота не имела никакой цены; люди обращали на нее внимания не более, чем на воздух, которым они дышали.
В небольшой компании, собравшейся еще перед тем, как глайдер въехал в село, находилась застенчивая смуглая девушка - Ньяра, как ее представил Элвину Хилвар. Юноша и девушка явно были очень рады увидеться вновь, и Элвин ощутил зависть к их счастью. Хилвар откровенно разрывался между своими обязанностями сопровождающего и желанием остаться с Ньярой наедине.
Трагично, - сказал он, - что две выжившие ветви человеческого рода оказались разделенными в течение столь огромного промежутка времени. Когда-нибудь мы, может быть, узнаем, как это могло случиться; сейчас же более важно устранить этот разрыв и не допустить, чтобы он произошел вновь.
Будучи в Лисе, я протестовал против их представления о собственном превосходстве. Они могут научить нас многому, но и мы их - не меньшему.
