India is dwelling to just about one and a half billion individuals, an enormous potential marketplace for 3D printed healthcare purposes.
3D Printing Trade visited the Additive Manufacturing Society of India’s (AMSI) convention in Bangalore to study extra about using additive manufacturing on the earth’s second most populated nation. At AM 2023, we heard from medical consultants how they hope know-how may change the lives of hundreds of thousands.
“Incorporating 3D printing applied sciences within the healthcare sector is a game-changer. It has the potential to rework many lives by offering reasonably priced, custom-made medical units and options to hundreds of thousands of sufferers,” stated Dr. Anil Kumar P R, Scientist, Biomedical Wing, Sree Chitra Tirunal Institute for Medical Sciences and Expertise (SCTIMST).
Dr. Kumar defined that in India, the healthcare sector adopting 3D printing at a speedy tempo. Principally, it’s used for orthopedic and dental purposes with steel 3D printed components. Polymer 3D printing can be on the rise.
This text will present insights into the panel dialogue addressing the most recent developments of 3D printed biomedical purposes: supplies, applied sciences, adoption, requirements and laws.

Supplies because the constructing blocks in medical 3D printing
Dr. Shiny Velayudhan, Scientist ‘E’, Biomedical Expertise Wing, SCTIMST says the main target of medical 3D printing could be broadly divided into two classes: 3D printing of implants and bioprinting, which entails 3D printing with dwelling cells. For load-bearing purposes, clinicians go for steel, at the moment titanium. Clinicians additionally work with ceramics, that are biocompatible supplies that are perfect for 3D printing implants and different medical units that have to be built-in into the physique. Some widespread ceramic supplies utilized in medical 3D printing embody TCP, bio black, or hydroxyapatite.
In keeping with Dr. Velayudhan, these ceramic supplies are usually not very sturdy, which is unsuitable for top load-bearing purposes. Because of this, these supplies are employed for maxillofacial purposes. “Clinicians are on the lookout for supplies which might be shapeable, which might be simpler to work with the scalpel. Consequently, they like supplies which might be composite, both ceramic or polymer,” explains Dr. Velayudhan.
Bioprinting is an rising class inside medical 3D printing. The “greatest materials,” in keeping with Dr. Velayudhan, is collagen, noting it’s insoluble in water and could be tough to work with. Utilizing an acidic medium can overcome some challenges right here, she provides. “Concerning bioprinting, we print with cells, and cells die when the pH is above or under 7.3 to 7.8. Thus, collagen can’t be instantly used as a printing medium. Now we have to work with denatured collagen, which could be difficult. So, clinicians modify the gelatin and use it as a medium for bioprinting,” stated Dr. Velayudhan.

Medical 3D printing: applied sciences and adoption
As within the aerospace sector, 3D printing has “proved its mettle” for orthopedics and dental purposes, says Dr. Suman Singh, Principal Scientist & Head, MSSA, Central Scientific Devices Group (CSIR-CSIO), Advisor at Indian Girls in 3D Printing (IW3DP). She says, “Clinicians are keen to make use of custom-made implants created utilizing 3D printing supplies and applied sciences. However on the flip facet, some clinicians are reluctant as a result of they don’t wish to go into the nitty gritty of any testing validations, laws, and so forth. So, except we put together ourselves for such phases, it’ll be very tough for the adoption and commercialization of those applied sciences.”
Dr. Singh believes bioprinting is a blooming space, however at current, it’s “very nascent.” In keeping with her, “the broader 3D printing business shouldn’t be that a lot explored within the Indian market. Purpose being, there are not any motion plans, authorities insurance policies, laws, and so forth.,” she argued. Because of this, the adoption of 3D printing, whether or not it’s in biomedical or some other vertical received’t be potential with out correct consciousness and motion plans.
“We have to go deeper into the engineering facet to really make tissue engineering potential, which is the science behind engineering a cell to develop into a tissue after which probably a number of tissue varieties. Adoption and consciousness of 3D printing applied sciences within the medical sector has the potential to finish organ transplants that exist on the earth,” stated Alok Medikepura Anil, Co-Founder and Director at Subsequent Massive Innovation Labs (NBIL).
Concerning supplies, 3D printers and their capabilities, panelists spoke about PEEK, which is a cloth that has biocompatibility and is already accredited. “This materials can be utilized for sure implants and rotating buildings that might be 3D printing utilizing common 3D printers proper from FDM applied sciences, SLA, SLS, and so forth,” stated NBIL’s Medikepura. “What we an organization, deploy for bioprinting is a pneumatic-based extrusion system, the place the uncooked materials might be within the type of pellets, or it might be within the type of semi-liquid materials that’s pneumatically managed by a system to providing precision.”
Want for requirements and laws
Dr. Velayudhan argued, “When experimenting, us clinicians consult with ISO and (Organisation for Financial Co-operation and Improvement) OECD requirements, however for 3D printing particularly for bioprinting, we wouldn’t have any set requirements. Now we have to consult with analysis papers as a substitute, which many industries and regulatory our bodies don’t think about, they ask us which customary is it? Thus, we’re once more caught there. Because of this, we want insurance policies so these processes could be streamlined.”
As for bioprinting, clinicians are at the moment challenged by scale. “There must be a know-how that enables for scaling as much as the human anatomical measurement,” she stated. “To do that, the employed bioprinter have to be very quick, as most of them are very sluggish, which is a problem as a result of dwelling cells can’t be printed for hours at a time. Requirements and laws are the muse for a protected and efficient bioprinting future. With out them, we’re constructing on sand. We want clear requirements and laws to information the event and use of bioprinted tissues and organs and to help the event of latest bioprinting applied sciences.”
Medikepura stated, “India must take a management place on this rising know-how, the sphere of additive manufacturing. For this to occur, regulatory insurance policies must be in place prepared for mainstream client adoption occurs.”
NBIL’s Co-Founder noticed that the Central Medication Commonplace Management Group (CDSCO) and medical councils are usually not as effectively outfitted to deal with a biomaterial that may be accredited to be used inside a human. He famous many researchers who’ve developed progressive biomaterials are combating CDSCO approval. One optimistic signal is that the U.S. Meals and Drug Administration (FDA), revealed the Modernization Act in December 2022, which is permitting pharmaceutical corporations to begin taking a look at computer-based fashions, corresponding to synthetic intelligence (AI) vs. fashions and even alternate options to animal testing, corresponding to human-like tissues that may be developed within the lab utilizing bioprinters.
“Pharma corporations have acquired a inexperienced gentle from the bigger regulatory physique to go forward and use such fashions for improvement of the brand new vaccines, for instance, which permits for fast-tracking the drug improvement course of. It saves each loads of taxpayer cash in addition to the time to marketplace for important medication out there,” concluded Medikepura.
