With evolving technology of 3D printing, the cost of 3D printing is also decreasing. This is making prosthetics and custom implants more affordable compared to the traditional methods or technology.

 

Let’s take a deeper dive and understand the specific ways in which 3D printing is making a difference in the health industry, specifically in the field of implants and prosthetics.

Custom implants for personalised healthcare 

One of the most ground-breaking applications of 3D printing technology in the field of medicine is the development of custom implants. Implants are devices that are surgically inserted into the body to replace missing or damaged parts such as joints, blood vessels or bones. Traditionally, these implants are mass-produced in standard sizes, but they often require adjustments at the time of surgery to fit a patient body. This could lead to longer recovery time, complications, and even additional surgeries.

The development of custom Implants has proven to be one of the most ground-breaking applications of 3D printing technology in the field of medicine. Implants can be understood as devices that are surgically inserted into the body of the patient to replace missing or damaged parts such as blood vessels, joints, or bones. Traditionally, these implants or devices are mass-produced in standard sizes, hence requiring adjustment very often at the time of surgery to fit a patient’s body. This traditional approach could lead to longer recovery time, further complications, and even additional surgeries.

How 3D printing is transforming custom implants: 

● Perfect Fit:

Doctors or surgeons can design implants specifically tailored to the unique anatomy of the patient using 3D printing. 3D models of the body part of a patient can be created using imaging techniques like CT scans or MRI. Therefore, a custom implant can be printed to fit seamlessly or perfectly into the body of the patient.

● Reduced surgical time:

The time taken for the entire surgery can be dramatically reduced as the implant is pre-customised to fit perfectly from the very beginning. This means, surgeons need not spend extra time, modifying or adjusting implants during the procedure, hence leading to shorter surgeries and faster recovery.

 ● Improved functionality:

Implants that are customed, especially for bone repairs or joint replacement, are made in such a way that they mimic the original shape and function of the body part. This improves the overall functionality and enhances the life of the patient after the surgery.

 

Example: In the year 2015, a patient in China became the 1st to receive a titanium jaw implant that is printed using 3D printing technology. Using a CT scan of the patient’s skull, a custom jawbone was printed to fit perfectly and was successfully implanted, helping the patient regain normal functions.

3D printing and Prosthetics: Revolutionising Limb Replacement

3D printing also has another area where it significantly impacts, and that is the creation of prosthetics. Traditional prosthetics can be time-consuming, expensive, and sometimes uncomfortable for the wearer. It comes with a one-size-fits-all approach that doesn’t always consider the unique and individual needs of the patient. On the other hand, 3D printing offers the possibility to produce customised prosthetic limbs that are lightweight, functional, and most importantly affordable.

Key benefits of 3-D printer prosthetics:

● Customisation:

Each of the prosthetics can be tailor-made to fit the individuals, unique measurements and preferences. This is especially crucial for children whose limbs grow quickly, hence requiring frequent prosthetic replacements.

 

● Affordability:

Traditional prosthetics can be extortionately expensive, with some of them costing around thousands of dollars. 3D printer prosthetics on the other hand, can be made at a fraction of the cost. Therefore, 3D printer prosthetics are opening up access to life, changing prosthetic technology for more and more people.

 

● Speed of Production:

3D printed custom prosthetics can be made more quickly compared to traditional ones. This means patients no longer need to wait for weeks and months for a prosthetic to be designed fitted and manufactured.

 

● Lightweight and Functional:

3D printing enables the creation of prosthetics with complex geometry that are both lightweight and strong, making prosthetics more comfortable for the patient to use and also allowing them to function more naturally.

 

Example: Organisations like e-NABLE use 3D printing to create custom prosthetic hands for children and adults. Thus, disorganisation has been able to provide free prosthetic limbs printed using 3D printing to people in need, hence improving their quality of life significantl

Personalised surgical planning, and anatomical models

Not only does 3D printing technology create prosthetics and custom implants, but it is also transforming surgical planning. This means surgeons can now utilise 3D printed anatomical models to deeply understand the unique condition of a patient in a much better way and hence, also plan their surgery with greater precision. These models are created from CT scans or MRI data and can provide detailed representations of the body, organs, blood vessels, bones, and even tumours.

How 3D printing can help in surgical planning:

● Improved Visualisation:

Surgeons can manipulate and hold 3D printed models, providing them with a deeper understanding of the patient’s anatomy and the challenges they might face in the surgery they would be performing. As a result, it leads to fewer errors and improved outcomes.

 

● Pre-surgery Testing:

The feasibility of testing different surgical techniques on models that are 3D printed is possible before performing the actual procedure. This helps the surgeons to get hands-on practice, hence refining the process and minimising any possible risk during the live surgery.

 

● Better Communication with Patients:

With 3D printed models, patients can understand their underlying condition and the proposed surgical approach that is to be performed on them. This improved or better communication can lead to more informed decisions and a great sense of confidence in the treatment plan of the patient.

  

Example: in complex cases like the removal of heart, surgeries and tumours, 3D printed models have been used to create exact replicas of the affected area. Surgeons have been able to rehearse the procedure beforehand, hence resulting in better precision and fewer complications in the surgery.

 

The future of 3D printing and medicine

The potential that 3D printing holds in the field of medicine is far from being fully realised. As this technology advances, we can expect more and more exciting developments in the field of custom implants, surgical planning and prosthetics. Some of the most promising areas of 3D printing include:

  

● Bio-printing:

The next advancement or frontier for 3D printing in the field of medicine is the printing of biological tissues and organs. While it is still in its early stages, bio-printing has the potential to revolutionise organ transplantation and tissue engineering.

 

● Smart Implants:

3D printing can also be used to create smart implants that monitor the health of a patient in real-time, providing feedback on inflammation, healing, or potential complications.

 

● 3D Printed Drugs Delivery:

Researchers are exploring the possibility of using 3D printing to create custom drug delivery systems that release medication in a controlled manner, tailored to the needs of an individual.

 

As 3D printing technology continues to evolve in many industries, it will only become more integrated into the healthcare and medicine industry, offering solutions that are innovative and can improve patient care and treatment outcomes.

Conclusion

3D printing is undeniably revolutionising the industry of medicine and healthcare, particularly in the development of prosthetics and custom implants. By providing tailored and cost-effective solutions that fit the unique needs of each patient, 3D printing technology is improving the quality of life for individuals or patients with medical conditions that require prosthetic limbs or implants. Furthermore, with the potential it holds for innovation in smart implants by printing and personalised drug delivery. The future that 3D printing technology holds in the field of medicine looks brighter than ever.

What is 3D Printing? How does it work?

What is 3D printing?

It’s now time to stop limiting your ideas and thinking about the impossibilities. With digitalization at its peak, it has something more to offer. 3D printing can change the game and is currently turning tables in the market, where there are endless needs and demands to meet.

Why choose 3D printing? Why not?

It’s good for the environment and renewable. Some of the materials are biodegradable. This explains why it’s a great choice.

We need technology that meets the demands of our fast-growing world. It should be quick, reliable, affordable, and environmentally friendly to better serve our needs.

Let’s understand the concept of what exactly is 3D printing. Imagine something in your mind, like a picture, model, or decoration. It can be anything you want.

Now what 3D printing does is make that idea come to reality by printing it into a complete 3D model. It is not very convincing until we understand how it works.

Think of how architecture works or how engineers build houses. They first have a plan, then a model, and then the implementation of the plan in a real-life model. 3D printing is quite similar to that. While building a house, the builders stack bricks on bricks, and in that sort of manner, a house can be built, and in the sort of same manner, 3D printing works.

Additive Manufacturing involves stacking materials on top of each other until the model is finished. This process allows anyone to easily create complex structures that are usually difficult to build with traditional methods. Let’s understand some important steps to follow during the printing process.

Designing: It is the initial step. An idea or a design is what drives the idea of printing. Someone creates this using CAD (Computer-Aided Design) software.

With the help of these software or tools, you can make designs on your computer and save your design as a file that a 3D slicer can read. Such files can be STL or OBJ files too. Some models already appear online, and users can download them for free or purchase them for printing.

Slicing: It is the step that follows next. This is the process where the design will print into a 3D model. This phase makes the printer easily read the 3D model by segmenting it into layers.

Different software also plays a role in the slicing process.

Some of the software used are “Cura,” “Prusa Slicer,” “Chitubox,” etc. These tools break the design into horizontal layers and create a file called “G-code.”

These tools divide the design into horizontal layers. They create a file called “G-code.” This file tells the printer how to print the model. It includes instructions on speed, any necessary support, and the direction for placing the material

Printing Methods: We can find various ways of printing our 3D model, and each kind uses different technologies. Some of the most commonly used technologies are as follows:

  • FDM (Fused Deposition Modeling): This is the most common type of 3D printing. In this type of printing, the process heats the plastic filament first, and then layers the softened plastic to build the 3D model. People find them very affordable and, at the same time, easy to use.
  • SLA stands for Stereolithography. It is a method that uses liquid resin. A UV laser or UV screen hardens the resin. This creates the shape of the models. This method gives a smooth and detailed finish to the 3D models.
  • SLS (Selective Laser Sintering) is a method that uses a laser. It fuses powdered materials like metals or nylons. This process turns them into solid materials or specific shapes.
  • MJF (Multi Jet Fusion): MJF uses a fine powder and a binding agent to build parts layer by layer, followed by a fusing process. It’s known for producing durable, high-quality parts with excellent detail and strength, making it ideal for functional prototypes and end-use parts.

3D Printing: After the model has been sliced into G-code, which can be read by the printer. The next step is to print the model. The machine, or more specifically, the printer, will read the G-code and print accordingly. The printing period depends on the sizes of the models, respectively. The larger the size of the model, the greater the time is to be taken, and vice versa.

Post-Processing: It is the last step. After the model has been printed, there needs to be a step where the quality or any defect needs to be checked. This is the step where any excess material is cut off and the product is cleaned so as to be presented at its best. Some of the important ways used in this step or process are support removal, sanding, painting or coating, and curing.

It’s quite fascinating to see how technologies have risen and how ideas have worked out and implemented in the most sustainable ways. 3D printing can be grouped as one of those sustainable ways to produce raw materials or products that can be used widely in many different fields. Sustainable because of the choice of the raw materials 3D printing requires. Let’s talk about the kinds of materials used to print these models.

  • PLA (Polylactic Acid): A biodegradable product made from cornstarch. This material can be printed effortlessly.
  • ABS (Acrylonitrile Butadiene Styrene): A heat-resistant, durable material. They can sometimes be tricky to print with.
  • Nylon: A strong and flexible material. This is often used in parts where it needs to bear wear and tear or stress and force.
  • Metal powders: These materials are used in printing to meet industrial demands and applications. Some of the metal powders that are used can be steel, titanium, or even aluminium for the production of functional parts in industry demands.

3D printing can serve various fields of demand in today’s time and in a short amount of time. Many industries demand various types of models for either functional needs, decorative needs, or even education. To shed light on why 3D printing can be a big hit and how it is turning games in the market, we must understand how it is being used. 3D printing serves as a support to all the engineers and designers by helping them create an effective prototype. Not only this, but also in the field of medicine and dentistry, 3D printing can be used for creating custom prosthetics, dental implants, and models for surgical planning. The education field requires models for the purpose of a better and more detailed understanding of complex subjects like human anatomy or parts, geometries, design, and engineering. The automobile and aerospace industries also now demand 3D-printed parts, as it is lightweight, durable, and also have detailed complex structures that would most probably be difficult if they were produced in the traditional ways.

 3D printing works for almost anything and any design. Whether it be a functional product or be it a new business idea create and bring your limitless and unique idea to life for the world to see.
