3D Printing Technology in Healthcare (Medical)

In healthcare, 3D bioprinting is used to create living human cells or tissues for regenerative medicine and tissue engineering. 3D printing is also used to make precise, custom-made pharmaceutical products.

Many branches of the medical industry benefit from 3D printing, including orthopedics and dentistry. Technology offers exciting new opportunities for personal care and the manufacture of more effective medical devices.

3D technology has transformed healthcare for more than 20 years. It is used in applications ranging from the development and manufacture of specialized devices to the planning of complex clinical procedures to more effectively train future medical professionals. And that’s just the beginning.

3D printing in health care

The medical industry is recognized as being the most advanced in the way new treatments and methods are developed. Not to mention the technology that drives all of this. There is no shortage of miracles, and they keep on happening. Now is the arrival of 3D printing in healthcare.

The medical industry has increased and increased, among others, through the use of 3D printers. Healthcare 3D Printing enables healthcare professionals to offer new forms of care to patients in a variety of ways. 3D printing is used to develop new surgical guides for cutting and drilling prostheses, and for making patient-specific copies of bones, organs, and blood vessels.

Recent advances in 3D printing in healthcare have resulted in lighter, healthier and safer products, shorter waiting times and lower costs. Special spare parts can be customized for each person. It enhances patient understanding by health care professionals and increases patient comfort by allowing interaction with products tailored specifically for their anatomy.

Why 3D printing Require in health care sector

Adaptation

Due to the individuality of the healthcare sector, 3D printing is the ideal solution for this industry. In contrast to producing many identical parts, 3D printing allows the manufacture of special prosthetic and orthopedic devices that are tailored to the patient’s specific anatomy. This increases their suitability.

Leadtime

Creating new tools can be time consuming and expensive. Even if it is made internally or outsourced. In critical situations, the long waiting time can literally be a life threat. Healthcare 3D printing provides designers and engineers with the tools to quickly create and replicate designs.

In addition to faster prototyping, communication can be more efficient if realistic prototypes are used. Feedback from doctors and patients is an important part of the success of any medical device. Combined with speed, these design improvements can be implemented. 3D printers are so accurate that custom parts can be designed and shipped for print in the very shortest time. Within a few hours, it will be possible to redesign medical instruments based on immediate feedback from the surgeon. Who is going to use it and print a new scoring model in no time?

The fast feedback cycle accelerates design development. Manufacturers can also use preliminary 3D printed parts to aid in early clinical trials or commercialization while the final design is still being adjusted. The time to print parts is often much faster than traditional production methods, but it still takes a lot of time to convert scanned data to get a print file. So for more pressing injuries, this is not the ideal solution.

cost

Making special parts and devices requires a lot of detail. If the process is completed manually, there is a risk of human error and this can make the project come back in cost and time. However, thanks to 3D printing, doctors can do several iterations before printing to identify possible defects and make sure the final product is perfect.

In addition to the ability to make complex parts to order, healthcare 3D printing is best for low volume production, so costs are reduced as efficiency increases. Expensive machining or machining processes are no longer required. They also reduce waste, which further lowers costs.

Sterilizable

Due to the application of several parts used in the medical industry, sterilization is an important property of the material. 3D printing knows a lot of strong, lightweight, and sterilable materials, with PEEK and Ultem being the best.

complexity

While conventional manufacturers may have previously tried to create complex organic shapes, the designs that 3D printers can now produce are probably limitless. The new composites and hybrid plastics allow the manufacture of body parts with increased strength and light weight. By selecting the right material and combining it with a truly accurate and precise design, patients benefit from increased quality, comfort and freedom.

Common uses of 3D Printing in Healthcare System

Advances in 3D printing technology in medicine have made a major contribution to health care. For patients, new tools and therapeutic methods developed through 3D printing can bring a new level of comfort and personalization to treatment.

Anatomical training and replicas

3D Printing Technology in Healthcare (Medical)

While the focus is on 3D printed implants and medical devices used by patients, creating anatomical replicas is one of the biggest uses. Doctors today use models created by 3D printing of patient scanning data to improve disease diagnosis, clarify treatment decisions, plan planned surgical procedures before actual treatment, and in some cases even put into practice.

The model allows the doctor to understand the patient’s anatomy, which is difficult to visualize, especially when using minimally invasive techniques. The models also help to determine the exact dimensions of medical devices. Doctors can also use the model to explain upcoming medical procedures to patients and their families and to communicate surgical steps to their colleagues.

To reduce costs, several institutions have developed methods for surgeons to practice and plan operations on inexpensive dolls transplanted with patient-specific 3D-printed models. Surgeons can now better understand how the procedure must be performed to touch and feel the characteristic parts of the patient’s anatomy. FDM printers are ideal for basic geometric surgical models that do not require a high level of detail or contain complex functions.

surgical equipment

Doctors use tools to help with surgery. Usually made of titanium or aluminum. With healthcare 3D printing, doctors can precisely create tools that fit a patient’s unique anatomy. With the help of 3D printing tools, restorative procedures (screws, plates and implants) can be placed more precisely, resulting in better postoperative results. 3D FDM printing technology is ideal for low cost, repeatable prototyping to optimize tool design.

prosthetic

3D Printing Technology in Healthcare (Medical)

Nearly 200,000 amputations are performed in the United States each year. Replacing or changing it can be time consuming and expensive. Since prostheses are personal items, each one has to be made to order or according to the needs of the user. 3D printing changed all of this and is now used regularly to create patient-specific prosthetic components that closely match the user’s anatomy.

3D printed tools using in medical fields

Patient-specific surgical models

3D printed anatomical models of patient scan data are increasingly becoming a useful tool in today’s personalized precision medicine practice. As cases become more complex and operating room efficiency for routine cases becomes more important, visual and tactile reference models can improve understanding and communication within the OR team and with patients.

3D Printing Technology in Healthcare (Medical)

Health professionals, hospitals, and research institutions around the world use 3D anatomical models as reference tools for preoperative planning, intraoperative visualization, and sizing or pre-assembling medical devices for routine and highly complex procedures documented in hundreds of publications. .

New medical equipment and instruments

3D printing has become synonymous with rapid prototyping. The ease of use and low cost of in-house 3D printing have also revolutionized product development, and many medical instrument manufacturers have adopted the technology to create new medical devices and surgical instruments.

More than 90 percent of the top 50 medical device companies use 3D printing to accurately prototype medical devices and medical devices for easier testing.

According to Alex Drew, a mechanical engineer at DJO Surgical, a global medical device company. “Before DJO Surgical imported [Formlabs 3D printers], we relied almost exclusively on outside suppliers for prototype printing. We currently have four Formlabs machines and the impact is strong. Our 3D printing speed has doubled, costs have been reduced by 70 percent and level of detail. on the mold allows the design to be clearly communicated to the orthopedic surgeon. “”

Affordable prosthesis

Hundreds of thousands of people lose limbs each year, but few are given access to prostheses to regain function.
Simple prostheses are only available in a few sizes, so patients should do what suits them best, while bespoke bionic devices mimic genuine limb movement and grip relying on the muscles in the remaining leg to assist them. only available to patients with the best health insurance in developed countries. This is especially true for children’s prostheses. As the children grow up and the adventure begins, their dentures will inevitably grow out and require expensive repairs.

The difficulty is the lack of a production process that allows custom parts to be made at affordable prices. However, an increasing number of prosthodontists are able to take advantage of the incredible freedom of 3D design to remove this high financial barrier to treatment.

Insoles and correct orthotics

Many of the same high financial barriers to prosthetic treatment are characteristic of areas such as orthotics and insoles. Like many other patient-specific medical devices, traditional orthotics are often unavailable due to their high cost and taking weeks or months to manufacture. This is no longer necessary with 3D printing.

The example of Matthew and his son Nick came to mind. Born in early 2011, labor difficulties led to cerebral palsy, which affects nearly 20 million people worldwide. Matthew is inspired by his son’s unwavering desire to go beyond the boundaries of his condition, but he is faced with inadequate and uncomfortable choice of a standard pre-made brace for his son or an expensive consumer solution that will take weeks or months to give birth only to quickly age by growing child.

Bioprinting, tissue engineering, 3D printing organs and so on

Currently, conventional ways of treating patients with severe organ damage include the use of signatures, transplanting tissue from one point to another in the same individual’s body, or organ transplantation from a donor. Researchers in the fields of bioprinting and tissue engineering hope to change that soon and be able to produce tissues, blood vessels and organs if needed.

Bioprinting 3D refers to using an additive manufacturing process to store a material known as bioink to create tissue structures that can be used in the medical field. Tissue engineering refers to a variety of emerging technologies, including bioprinting, for growing tissue and replacement organs in a laboratory for use in the treatment of injury and disease.

With precision 3D printing, researchers like Dr. The University of Sheffield’s Sam Pashneh-Tala opens up new opportunities for network engineering.
