Nowadays, in the news, we can see the development of 3D printing technology (also known as additive manufacturing) in the medical field almost every day. For example, scientists are exploring the use of 3D printing technology to create micro-robots that deliver drugs in the human body; print artificial skin containing hair follicles and sweat glands for transplantation; and even use living cells as materials to print human organs.
What is even more exciting is that many technologies are no longer conceived, but have been put into practical use. A Chinese hospital completed a 3D printed elbow joint transplant for a male injured at work. A Welsh surgeon used a 3D printer to repair a patient's facial bones. A hospital in the United States uses 3D printing technology to make a stent that opens up the airway blocked by the baby.
In fact, 3D printing has long played an important role in the health field. A typical example of this is dentistry, where more than 19,000 crowns and bridges are manufactured every day using 3D printing technology. Each year, 3D printers produce 17 million orthodontic appliances. 3D printing has a subversive effect on audiology, and 90% of customized hearing aids in the United States are manufactured in 3D printing.
The Wallace Report 2014 shows that 14% of the world's companies providing 3D printing equipment, materials and services come from the medical field. In addition, ancillary services such as 3D imaging, scanning, design and modeling are rapidly evolving to form a complete 3D printing ecosystem.
Why can 3D printing be popular in the medical field?
First, many diseases and injuries are caused by biomechanical problems such as fractures, joint aging, and spinal dislocation. In the past, such problems were difficult to cure because each person's physiological structure was unique, and a standard unified external device could not solve everyone's problems. The 3D printed product perfectly solves this problem. It is completely in line with everyone's body structure. In addition, it greatly reduces the cost of customization and makes the seemingly contradictory concept of mass customization possible.
Secondly, some artificial structures that are flexible, semi-fixed or absorbable by the human body, such as valves and blood vessels of key organs, are difficult to manufacture by conventional methods. And 3D printing technology can solve this problem.
Finally, 3D printing bypasses complex infrastructure and logistics issues. As long as the designed pattern is sent to the printing terminal, the 3D printer can be produced within a short distance from the hospital. This is a huge boon for emerging markets with underdeveloped logistics channels and for people in remote areas.
Despite the benefits and prospects of 3D printing applications, it still faces a lot of uncertainties and risks. Will it change the pattern of the entire medical market in the future, or is it only active in small-scale niche markets?
Through analysis, we believe that the market revenue of 3D printed medical products will reach 5 billion US dollars by 2020. At present, the "killer application" of 3D printing - those products that can attract medical personnel to abandon old technology and can not be reached by traditional methods - are few. At present, the only thing that can be called a killer application is the oral corrector, which will become the main growth area of ​​the 3D printing market in the future. If there are no other killer applications, the development of 3D printing products in the short term is limited.
However, in the medium to long term of 5-10 years, we believe that dental products, such as filling materials, cell cultures and soft tissue products, will gain market share. As biomedical companies are actively involved in product development and rapid prototyping in this area, 3D printing products may gain rapid development in the long term, especially in the market applications of cell tissue engineering, pharmaceutical innovation and microfluidic chips.
