Research Heralds 3D-Printed Organs and even Hearts

3D Perspectives

Few would have guessed the trajectory from 1970s inkjet printers to 3D printed organs consisting of human cells, yet, that’s where we’re headed. 3D printers apply layers of melted plastic to create complex objects, from the silly to the serious, including personalized prostheses such as eyes, ears or knees. A patient at the University Medical Center Utrecht, the Netherlands, recently was the first to receive a custom 3D printed plastic skull. Written by Catherine Bolgar.

All About Acrylic Plastic

3D Printing Hub

Plasticizers are used as additives to improve impact resistance, lower glass transition temperature, or enhance processing properties. Medical : Acrylic has a favorable compatibility with the human tissue. Electrical : Plastic optical fiber used for short-range communication is made from PMMA or Acrylic plastic. Hence, CNC machines are a good fit with acrylic plastics. Acrylic is not the strongest plastic and is actually quite brittle.

Carnegie Mellon University: 3-DIY – Printing Your Own Bioprinter

Additive Manufacturing

The researchers — Materials Science and Engineering ( MSE ) and Biomedical Engineering ( BME ) Associate Professor Adam Feinberg, BME postdoctoral fellow TJ Hinton, and Kira Pusch, a recent graduate of the MSE undergraduate program — recently published a paper in the journal HardwareX that contains complete instructions for printing and installing the syringe-based, large volume extruder (LVE) to modify any typical, commercial plastic printer.

Inside the lab where scientists are 3D-printing a real working trachea

3D Printing Review

The trachea can get damaged by tumors, during intubation—when a plastic tube is fed down the trachea to keep the windpipe open during surgery—or in an accident. Goldstein could then print out 3D plastic models of replacement parts as many times as necessary, working with surgeons to get the exact right fit. Once they were happy with the plastic models, the real thing could be printed. One is just for printing plastic.

Bioprinting in 3D: Looks Like Candy, Could Regenerate Nerve Cells

3D Printing Review

Tolou Shokuhfar and colleagues are developing techniques using 3D bioprinting to generate human tissue. Stainless steel hydraulics and thin black tubes line the back edge, which lead to an inner, topside box made of red plastic. In fact, the tissue-printing machine is more like a sci-fi future in the flesh—and it has very real medical applications. The key is developing the right “bioink” or printable tissue.

How 3D Printing Boosts Innovation in the Medical Field

Shapeways Blog

Models of organs, for example, can be printed in a material that resembles human tissue, like silicone, and can be a more affordable and less-stressful source of practice than using human cadavers. Instruments can be printed in a number of different materials depending on their needs, including titanium, stainless steel as well as sterilizable biocompatible plastics. Tissue Engineering. 3D printing provides many plastics and metals that are suitable.

Top 6 Reasons Universities Are Buying 3D Printers

PrintSpace

Universities such as Cornell University have been quick to use 3D printers and last year demonstrated the 3D printing of an artificial replacement ear, while North Carolina’s Wake University earlier this year has been experimenting with materials made from plastic-like substances along with living cells derived from rats, rabbits, mice and humans. Through the use of a bio-printer, which is capable of 3D printing human tissue, bone, muscle and ear structures have been created.

6 Future Applications of 3D Printing

Shapeways Blog

The field called 3D Bioprinting uses a bioink, made from human tissues and cells to 3D print the needed organ that will not only be fully functional but also compatible with the human recipient. But the 2D models do not accurately represent a human tumor and this leads to a difference in the treatment and the results. Scientists believe that 3D bioprinted tumor cells will accurately represent the human conditions.

This process – which consists of printing layer upon layer of a material, usually plastic, to make an object out of a 3D digital drawing – has been around since the eighties. Advances have also been made in bioprinting, which uses a so-called ink made of cells and human tissue. By Rebeca Ibarra, NY Daily News. The recent hype over 3D printing, also known as additive manufacturing, shoudln’t fool you into thinking it’s new.

Human Body Experience. It is a mixture of plastic and 40-50% recycled wood chips. Human Body Experience. The 3D printer NOVOGEN MMX Bioprinter of Organovo is now able to print human tissue. The method includes establishing a gelatinous base layer and on each transplant some living cells and thus to start the construction of a biological tissue with high cell stability.

Thus the original and still common alternative name of additive manufacturing. The machines print head squirts and melts plastic or metal powders not only to specific dimensions and shapes but increasingly specific material compositions. Most of the action today is around 3D plastic printers where we find what amounts to toys, mainly including hobbyists, experiments, designers, educators and artists. Not to denigrate the utility of printing in plastic.

One of These is Not Like the Other

Medical design companies and manufacturers are quickly fulfilling the demand for patient-specific care using 3D plastic and metal printers, as well as bioprinters that can create layers of human tissue. The next frontier in 3D printing for medical technology will be the printing of living tissue (referred to as “bioprinting” or regenerative medicine), where living cells are 3D printed to create a structure that is then implanted in the patient, explained Wohlers.
