The New 3D printing technique could make lab-grown organs more realistic

As much as 3D-printed organs have advanced, creating them is still a slow process that can damage the tissue. There may soon be a quicker and more effective method, however.

Researchers from the University at Buffalo and elsewhere have developed a 3D printing technique that’s 10 to 50 times faster than standard methods.

A tiny synthetic hand (shown above) that would have taken six hours to print took just 19 minutes — enough to minimize the deformation and cellular damage from earlier systems.

Can a 3D printer print organs?

This technique is called “cryobioprinting,” the Daily Beast reported. Building on the existing 3D printing method for tissues, the organs are made out of “bioink” derived from living cells and a gelatin-like substance. It’s applied to a surface until the desired organ’s tissue structure is created.

What is the future of 3D bioprinting?

Conclusion. 3D bioprinting is a rapidly emerging industry that could benefit both human and veterinary medicine. Advances in bioprinting have led to the production of higher resolution bioprinters, improved vascularization of printed tissues, and the generation of in vitro and in vivo tissue models.

How can 3D printing help humans?

3D printing is being used in the medical sector to help save lives by printing organs for the human body such as livers, kidneys and hearts.

Further advances and uses are being developed in the healthcare sector providing some of the biggest advances from using the technology.

How does 3D printing affect the medical field?

3D printing is used for the development of new surgical cutting and drill guides, prosthetics as well as the creation of patient-specific replicas of bones, organs, and blood vessels.

Recent advances in 3D printing in healthcare have led to lighter, stronger and safer products, reduced lead times and lower costs.

Can you 3D print a liver?

Scientists 3D-print human liver tissue in a lab, win top prizes in NASA challenge. Scientists have successfully grown liver tissue capable of functioning for 30 days in the lab as part of NASA’s Vascular Tissue Challenge.

Can you 3D print a pancreas?

A bioprinted pancreas could remove the need for animal testing. The design flow of a 3D printed pancreas begins as a transparent shape on a computer screen — engendering a tiny digital replica of the human pancreas.

But incredibly, it only takes 30 seconds to print the tissue out of a bioprinter, blood vessels and all.

How will bioprinting affect the future?

Bioprinting could eventually be the preferred platform to utilize human stem cells to produce artificial solid tissues and organs. The combination of 3D bioprinting with microfluidics allows the development of the next generation of organ-on-a-chip platforms.

How does 3D printing benefit society?

Benefits to society

3D printing leads to a reduction of wastes and thus, there is no requirement of reducing, reusing, and recycling the waste materials every now and then. … Due to the high degree of accuracy and precision, one can print even the slightest of variations neatly.

What is the importance of 3D printing?

The main advantages of 3D printing are realized in its Speed, Flexibility, and Cost benefits. For small production runs, prototyping, small business, and educational use, 3D printing is vastly superior to other industrial methods.

The new approach uses a combination of stereolithography with hydrogels. By precisely guiding photopolymerization, the team could quickly and continuously supply the necessary hydrogel solution and maintain “nonstop” growth.

The output is currently limited to “centimeter-sized” models, but it’s already well-suited to printing cells with built-in blood vessel networks. That will be crucial for the eventual production of human-sized organs.

How are artificial organs 3D printed?

3D bioprinting prints 3D structures layer by layer, similar to 3D printers. Using this technique, our research team created a porous structure made of the patient’s neural cells and a biomaterial to bridge an injured nerve. We used alginate — derived from algae — because the human body does not reject it.
