Applications of 3D Printing In Life Sciences

3D designing and printing have been breaking the barriers of their relevant fields and progressing into new areas for many years since their inception. These technologies have proven to be highly versatile and beneficial to the adopted areas. The life sciences are a reasonably new field employing 3D designing and printing in many areas that make life easier for humans worldwide.

Applications of 3D Designing And 3D Printing In The Life Sciences

3D designing and printing in life sciences are currently used in healthcare and food technology. Major applications lie in healthcare. Read on about the most popular applications of 3D designing and 3D printing in the life sciences. 

1) Healthcare: 

The number of practical applications in medicine is growing all the time, and researchers are working on a slew of new and potentially game-changing uses. 3D printing's precision, speed, and cost-effectiveness herald a new era of tailored medical care.

a) Prosthetics: 

Prosthetics is a very old field in the healthcare sector. Since ancient times, prosthetics have been used, allowing amputees to lead comfortable lives. Earlier prosthetics were created from wood or plaster by manufacturing techniques such as molding and/or machining. Such techniques are often made difficult by the labor-intensive nature of the process. 3D designing eliminates the need for creating molds or machining tough materials to create prosthetics. 

The design process can be done virtually, and manufacturing can be done automatically by 3D printers. Another advantage of 3D designing and printing, in this case, is that sturdier, cost-effective materials such as carbon fiber could be used to create prosthetics that are lighter yet stronger. Apart from saving the cost and time involved in molding or machining prosthetics, 3D designing and printing can be used to make prosthetics that offer more articulation and are more comfortable for the user.

There are a lot of 3D modeling software available that one can use to 3D design prosthetics and each of them has its own strengths and weaknesses, but we recommend using SelfCAD. SelfCAD is CAD software that runs on both Windows and Mac, and there is an online version that ensures that you work on your designs anywhere anytime. The software has a simple interface with tools well arranged the interface making it easier for anyone to get started with much ease without having to spend a lot of time learning how the program works.

SelfCAD also has an in-built slicer that is helpful in preparing your prosthetics for 3D printing. Hence you won’t need to switch to slicing software in order to generate the g-code that you will send to your 3D printer. Everything is done in one program.

b) Orthopedic And Dental Implants: 

Medical implants such as dental or orthopedic implants are often made of materials such as metals or polymers and are usually molded or machined from bigger pieces of material, causing wastage of material. Sometimes, these implants would not be able to match the proportions of the recipient and could cause discomfort and even disfigurement in the long run. Such could lead to metal poisoning if left in the body for prolonged periods. A viable solution is to create implants using 3D designing software to match the proportions of the recipient and create implants that are not only comfortable but also less risky in terms of causing conditions such as metal poisoning. 3D printing these parts will save a lot of the raw material from being wasted. Besides helping recipients regain mobility, 3D-printed implants offer comfort and better integration.

c) Organ Replacements And Soft Tissue Implants: 

 

Millions of lives are lost, in danger, or disabled for want of donor organs to replace defunct or damaged organs. Organs such as the heart, kidneys, and liver are some of the organs that are in high demand due to lifestyle-related diseases or even congenital conditions. These organs are often harvested posthumously from registered donors and are made available to recipients after long waiting periods. The scarcity of donors is one of the biggest problems faced by people who require replacements. Another issue in the case of organ replacements is compatibility problems which could trigger autoimmune conditions and result in the body rejecting the replaced organ or organs. 3D designing, coupled with stem-cell technology, enables healthcare professionals to develop replacement organs from the recipient organs and implant them into their bodies, with a better chance of being accepted by their bodies. Soft tissue organs and organs such as bones can also be designed and printed before being safely integrated with the recipient’s body. Synthetic organ development through 3D printing and stem-cell technology is a topic of interest among medical researchers worldwide. 3D-printed organs will likely be made available to the general public soon. Ligament injuries are common and challenging to recover from. Using a specific electrospinning method, scientists are working on manufacturing 3D-printed ligaments. Once the technique is established, it will become another tool in the medical arsenal. Researchers are also developing technology that could create a fully functional prosthetic eye in the future. They 3D-printed photoreceptors on a hemispheric surface, a predecessor to a 3D-printed eye that could cure blindness in the near future.

D) Medical Research: 

The utilization of 3D printing technology in medical research, particularly the latest advances in precise direct cell printing, allows for drug and therapy development as well as toxicity testing and speeds up the research process. One example is 3D printing to build tissues and organs to research how cancer and other diseases impact them. Because real items can now be exchanged via the internet as 3D printing instructions or 3D printing designs, this technology also improves collaboration between researchers and physicians.

e) Surgical Planning: 

The study of the anatomy and physiology of complicated organs or anatomical structures in preparation for surgery is known as surgical planning. Surgeons could use virtual 3D models to simulate complex surgical procedures. Surgeons could also utilize 3D-printed replicas to experiment with different approaches and rehearse before surgery. Patients might be able to utilize the models to understand better their condition and what to expect during surgery. Surgical planning using 3D printed models can save procedure or operation time and improve patient experience and clinical outcomes.

f) Medical Education And Hands-On Training: 

Human cadavers are already used for medical education and training, but 3D printing offers a viable alternative. The human anatomy may be correctly replicated using 3D printing technology from high-resolution CT imaging and other sources, including numerous copies in various sizes, which would be a significant leap in medical teaching. 3D design software could be used to create virtual models that could simulate bodily functions and help students learn better and grow into better caregivers.

G) Pharmaceutical Applications: 

In the world of drug delivery, 3D printing offers a lot of promise. Pharmaceuticals can be printed in customized doses for each patient, with layers optimized to provide rapid or prolonged drug release for a specific therapeutic effect. In addition, 3D printing technology for individualized medicine delivery devices is now being developed.

2) Food Technology: 

3D printing and designing can be used in various areas of food processing, from food preparation to packaging. The only significant difference is that the printer components, including the printing material, are of food-grade quality. There is a wide variety of 3D design software and 3D printing modules to make various products based on structure, application, and demand. Here are some examples of how 3D designing and printing are used in the food processing industry:

a) Personalized Nutrition Plans: 

Apart from their attention to shape and texture, 3D design software and 3D printing modules have an additional role. They take advantage of one of 3D food printing's main advantages: its capacity to function as a local, flexible production unit. Each 3D printer can be viewed as a mini-factory capable of generating a wide range of products, including those that are completely personalized. 3D food printing may also be used to create entirely customized food items in terms of composition, caloric content, texture, and flavor, making it a good fit for customized cuisine. Printed food products could suit most, if not all, of a consumer's needs in terms of flavor, texture, color, portion size, and kind of ingredients, as well as the overall composition of the product in terms of macro-and micronutrients, calories, and digestibility, among other things.

b) Plant-Based Meat: 

In terms of its environmental impact, the ethical concerns of raising cattle, poultry, and other livestock for slaughter, and their cruel treatment, the meat industry faces a lot of stigmas. Meat analogs from plant sources are part of a revolutionary movement that is gaining traction in response to the negative aspects of the meat business. Although plant proteins can be used to make structural proteins and natural components can mimic the flavor, plant proteins cannot easily recreate the fibrous texture of meat. This is where 3D printing and designing come into play. 3D printing and designing can be used to create a structure with a complex network of fibers that resembles the muscle fibers seen in meat.

c) Sweets And Baked Products: 

Confectionaries and baked foods are arguably some of the most labor-intensive culinary products, requiring a significant amount of time and effort from human resources to create complicated designs or structures. Complex arrangements can be made with 3D modeling without requiring much physical effort. Food technologists can now develop complex shapes and structures in a quarter of the time and without wasting any raw materials, thanks to 3D design tools.

Conclusion

In conclusion, 3D designing and 3D printing have many revolutionary applications in the field of life sciences. They make medical research more efficient, enabling better healthcare for the general population. Organ replacement, prosthesis, medical training, and personalized drug delivery are some healthcare areas that have been improved due to 3D designing and Printing. In food technology, 3D designing and printing make food processing more efficient and sustainable by reducing raw material wastage and producing cruelty-free products.
