What are the ethical issues of 3D Bioprinting?

Ethical challenge: ethics of untested paradigms: living cells. 3D bioprinting remains an untested clinical paradigm and is based on the use of living cells placed into a human body; there are risks including teratoma and cancer, dislodgement and migrations of implant. This is risky and potentially irreversible.

How much does a 3D Bioprinter cost?

Living tissue has been successfully printed with a $1000 3D printer while more specialized bioprinters cost upwards of $100,000. Other costs involved include bioinks which start at hundreds of dollars, associated research and the cost of highly skilled operators for 10 weeks or more per organ.

Can you 3D print a lung?

The lung, which is vital to breathing, is rather challenging to create artificially for experimental use due to its complex structure and thinness. Recently, a POSTECH research team has succeeded in producing an artificial lung model using 3D printing.

How far away are we from 3D printing organs?

Redwan estimates it could be 10-15 years before fully functioning tissues and organs printed in this way will be transplanted into humans. Scientists have already shown it is possible to print basic tissues and even mini-organs.

What is human organ printing?

Organ printing utilizes techniques similar to conventional 3D printing where a computer model is fed into a printer that lays down successive layers of plastics or wax until a 3D object is produced. … As the plastic is being laid down, it is also seeded with human cells from the patient’s organ that is being printed for.

What are the benefits of bioprinting?

Advantages of 3D Bioprinting: What the Future Holds

  • Bioprinting could replace organ donors. …
  • Bioprinting could prevent cell rejection. …
  • Bioprinting could replace animals in testing labs. …
  • Bioprinting can replace volunteers in drug testing labs.

How does bioprinting help society?

Bioprinting new tissues or organs for pediatric patients may allow for the new devices to grow with the child, reducing the need for multiple surgeries. That being said, expensive personalized therapies such as bioprinting also pose the risk of widening the ever-growing socioeconomic gap in medical treatment.

What are the disadvantages of 3D bioprinting?

Disadvantages include lack of precision with regards to droplet size and droplet placement compared to other bioprinting methods. There is also a requirement for low viscosity bioink, which eliminates several effective bioinks from being used with this method.

How expensive is Bioink?

As the market for cost-effective bioprinters is in its infancy, growth is fast and it is beginning to drive demand for compatible bioinks. Low cost systems are priced between $10,000 and $20,000, compared to an average high end professional system’s price of $170,000.

Is 3D printing of body parts expensive?

For example, according to the National Foundation for Transplants, a standard kidney transplant, on average, costs upwards of $300,000, whereas a 3D bioprinter, the printer used to create 3D printed organs, can cost as little as $10,000 and costs are expected to drop further as the technology evolves over the coming …

How much does Bioprinter cost?

Currently, low-end bioprinters cost approximately $10,000 while high-end bioprinters cost approximately $170,000. In contrast, our printer can be built for approximately $375.

How much does an artificial lung cost?

Lung transplantation cost at low-volume centers was 11.6 percent higher than high-volume centers. The average cost of lung transplantation across all centers was $135,622. Across all centers, 39 percent of recipients had an early hospital readmission, with an average cost of $27,233.

Do artificial lungs exist?

Artificial lungs could provide a stopgap for people recovering from severe lung infections or waiting for a lung transplant – although a transplant would still be a better long-term solution for those with permanent lung damage. Yet making artificial lungs has proven harder than making a mechanical heart, say.

Can liver be 3D printed?

Of the human liver, around 80% is made up of small functional units called hepatic lobules, and advances in 3D bioprinting are increasingly making it possible to replicate these building blocks, and create thicker, more viable soft tissue models.

Can organ printers replace the need for organ donors?

Artificial organs printed using bioink made from a patient’s own cells could eliminate the need for transplant altogether, removing the need for organ donors and reducing the risk of tissue rejection.

Can I get a 3D printed kidney?

3D printed kidneys could be the future of organ transplants. … The availability of healthy, suitable, local organ donors can never be guaranteed. It is impossible to arrange donors in advance. 3D printing technology is moving from an obscure gimmick to smaller 3D printers that people can use in their own homes.

What was the first 3D printed organ?

heart The team created a cell-containing bioink and used it to 3D print the organ layer by layer. Israeli researchers have created an entire 3D-printed heart made from human cells in what they say is a world first.

Can skin be 3D-printed?

Researchers at Rensselaer Polytechnic Institute in New York have developed a way to 3D-print living skin, complete with blood vessels. This 3D-printed skin could allow patients to undergo skin grafts without having to suffer secondary wounds to their body.

Can you 3D print cells?

A high-resolution bioprinting process has been developed: Cells can now be embedded in a 3D matrix printed with micrometer precision — at a printing speed of one meter per second, orders of magnitude faster than previously possible.

When did 3D printing in medicine start?

This was invented by Charles Hull in 1984. 3D Printing was first used for medical purposes as dental implants and custom prosthetics in the 1990s. Eventually, in 2008, scientists were able to produce the first 3D prosthetic leg.

Why is 3D bioprinting important?

The greatest importance of bioprinting lies in the resulting tissue-like structures that mimic the actual micro- and macro-environment of human tissues and organs. This is critical in drug testing and clinical trials, with the potential, for example, to drastically reduce the need for animal trials.

What are the positive impacts of 3D bioprinting on the life of humans?

Faster and more precise than traditional methods of building organs by hand. Less prone to human error. Less laborious for scientists. Organs unlikely to be rejected after transplantation.

Why is 3D bioprinting useful?

First, 3D bioprinting could reshape the pharmaceutical industry by dramatically lowering research and development costs by complementing pre-clinical animal models. Second, when the 3D bioprinting technique is sufficiently mature, it has the potential to solve the crisis of the current organ transplant waiting list.

We talked to three professionals in the 3D printing sphere, including Mages, about the pros and cons of the technology.


How do Bioprinters work?

Bioprinters work in almost the exact same way as 3D printers, with one key difference. Instead of delivering materials such as plastic, ceramic, metal or food, they deposit layers of biomaterial, that may include living cells, to build complex structures like blood vessels or skin tissue.
