Why 3D Printing is the New Frontier in Regenerative Healthcare?

Spread the love

3D scienceWhile there is not much of a dramatic improvement or life-altering change for home and office printers during the last 3 decades, this is in contrast to what has been happening in the world of 3D printing services. This aspect of 3-dimensional printing has taken on a different route instead. 

Otherwise known as the additive manufacturing method due to its progressive layer-by-layer approach in printing your subject material, much innovation has been made about it in the last 2 decades.

Consequently, the positive changes that it had and all its recent breakthroughs perked up the interest of industry leaders from various fields. They saw their potential benefit and all. Thus, they can use those in advancing their cause. 

Come the year 2000s, 3D printing technology entered the medical world. This came to happen by virtue of 3-dimensional printing devices, such as the ones intended for surgical instruments and prosthetics. 

As of this writing, both the medical space and the scientific community are testing out various kinds of bio-inks. This is in the hope of uncovering a breakthrough technique that can be utilized for printing human vital organs, cartilage, and bones. 

Regenerative Structure to Promote Long-Term Healing of Bones

UK’s Swansea University developed a bioprinting process that can create an artificial bone matrix. It is made from durable and long-lasting regenerative material.  

Right now, the treatment options we have for complex bone fractures will involve a surgical procedure known as bone grafting. This process will replace damaged or missing bones with cement-based materials.

However, there is a handful of limiting factors to this kind of treatment. One, there is the risk of inappropriate mechanical integrity and, two, it does not allow the growth of new bone tissues.  

Bioprinting here is more advantageous in the sense that you can opt to print them in the exact structure using regenerative biomaterial.

Such materials are usually made from collagen alginate, agarose, gelatine, polycaprolactone, and calcium phosphate. Over time, the bioprinted bones can fuse themselves with the natural bone of the patient. 

Functionality Challenge for a Beating Heart

A fully vascularised heart was successfully 3D printed by the American Friends of Tel Aviv University. This group of scientists made use of the fat tissue cells of a donor.

The fat cells needed to undergo partial culturing, reprogramming them in the process into heart cells. The 3D-printed heart came fully equipped with all the necessary ventricles, chambers, blood vessels, and cells. The said bionic heart was created based upon the medical images produced out of the donor patient’s own heart.  

As of this writing, this technology remains at its inception phase. The heart, which the said researchers have successfully 3D printed is comparable to the size of a rabbit’s heart, is not capable of pumping any blood. 

Team leaders of the said research group are looking forward to testing out their printed hearts. They intend to do it first in animals as their subject. But this may happen only if they figured out how to rescale the human organs and get them to beat.  

Better Alternative to Skin Grafting for Burn Patients

When it comes to addressing severe burns, our recourse is skin grafting. What the medical professionals do here is harvest the patient’s healthy skin. They perform this in that part of the body that is not burnt.

However, in some cases, there is not enough healthy skin anymore left on the patient’s body to use.  

A scanner may be taken advantage of to gauge the depth and the size of the wound. The role of the 3D printing machine here is to take in the said information and print the hypodermic, epidermic, and dermic skin cells at the corresponding depths. This will help in giving the wound good coverage. 

While the trial phase for this technology is taking on a forward direction, members of the said research team are holding their optimism high. They’re looking forward to having placentas and amniotic fluid as effective skin to patients. They believe in their potential in aiding severe skin burn patients to heal from their wounds.  

What is the Significance of Rapid Prototyping in Product Development?

Spread the love

Was there ever a time that you knew to yourself that your mind has just conceived a great product design, but you have no idea if it is going to be a hit or not?

Do you often find yourself struggling for words to say when trying to explain to your investors, business partners, or co-workers the concept or principle behind your product design or proposal?  

Rapid type prototyping can help you do all that with ease! 

This process is now dominating the center stage in the plastic parts manufacturing space and is taking it to the next level by making it possible for product designers and engineers to come up with top-caliber prototypes that have the look, the feel and vibe, and function of how a final product should be. 

Before delving deeper here, we need to define what rapid prototyping is all about.

Defining Prototyping

All designing processes begin first with a bright idea or concept. This will be followed either by a hand or digital design. Then, the design and its overall integrity can be initially tested by a prototype. It is that this point that 3D printing will come into the picture, to help in the creation of a product prototype. 

Rapid prototyping is simply the accelerated creation or development of a prototype. The purpose of which is to immediately help in demonstrating and showcasing distinct features and design of a product. 

This relies on 3-dimensional CAD (computer-aided design data) for its layout aspect and makes use of a 3D printing machine for the production phase. Since prototype versions of a product offering are usually developed using materials, not of the same as the final product, it is not easy to determine if they are durable enough or whatnot.   

Benefits of Prototyping a Product First 

  • Clear and helpful visualization of design concepts.

Rapid type of prototyping allows engineers and designers to demonstrate their design concepts and ideas with investors, business partners, developers, and potential clients. Simply put, to relevant people where their proposal matters the most. 

The process makes it easier for them to explain their ideas visually. Hence, necessary tweaks or design adjustments can be immediately identified and these changes can be implemented soon enough.  

  • Efficiency can be improved even before a prototype could be developed.

The usual practice for engineers and designers before the rapid type of prototyping became a fad is they need to wait in line for their requested prototypes if they want theirs built. This goes to show that if you want your product offering to have a prototype first, it is going to be an arduous process and an expensive endeavor also.  

Rapid prototyping concepts work to the advantage of everyone to whom they matter. It saves them valuable time, money, and effort. All of which are undeniably valuable resources for any business organization regardless of the industry they belong to.

  •  Designs are Customizable

Needless to say, this type of prototyping has our best interest in mind. Using this method, engineers and product designing teams can implement necessary modifications to a product design or feature before it comes into a full-fledged production. All with respect to a client’s specifications or needs. 

Like for instance, if a proposed change requires the use of small parts, you can now easily produce it within the prototype designing phase.   

  • Expedites time to market.

In the rapid type of prototyping, organizations are empowered even more because they can now hasten up their time to market their product offerings through this enhanced technology.

And as indicated above, necessary design and feature revisions can be implemented easily and quickly following physical testing and garnered feedback.  

In Summary

This prototyping concept makes it possible for product designers and engineers to continuously make necessary improvements to their offerings, even before they hit the market. 

Enhanced prototyping is a revolutionary technique we have nowadays that is helping manufacturing bodies to sustain further improvement of their product offerings in a cost-effective manner.
