BIOPRINTING INDUSTRY HIGHLIGHTS OF Q3 2017

By Cecillia Wong. -


New Methods 
A new method in bioprinting has been developed by an Oxford University spin-off company, OxSyBio, that will enable researchers to print and arrange cells in pre-determined 3D architectures. This novel method leverages the use of a lipid coating which encapsulates cells within protective nanolitre droplets during the printing process. Dr Alexander Graham, the lead author and scientist of OxSynBio, demonstrated the application of this technique with human embryonic kidney (HEK) cells and ovine mesenchymal stem cells (hMSCs). He was able to achieve high-resolution 3D geometries in the range of less than 200 microns while maintaining high cell viability. Learn more about this exciting work at their Nature publication – Scientific Reports. 

New Materials 
In the most recent development, a clay-based bioink was developed and shown to provide improved drug delivery properties. A team of researchers from University of Southhampton and the Technische Universitat Dresden in Germany used a synthetic nanosilicate clay called Laponite to create a 3D printable bioink that supports mesenchymal stem cell growth. The material is combined with alginate and methylcellulose produces properties that make it suitable for bioprinting and drug delivery applications. To learn more about this innovative bioink, check out their most recent publication in Biofabrication. 

Featured Application  
Researchers at the University of Gothenberg in Sweden reported successful bioprinting with induced pluripotent stem cells (iPSCs) in a nanocellulose-alginate bioink to create cartilage in vitro. The experiments involved a comparison study between the use of alginate versus hyaluronic acid and their findings showed superior results in the alginate-based bioink for creating cartilage tissue structures. Get more detailed specifics about their research in this Nature Scientific Reports publication.

How 3D Printing Will Revolutionize Henna Tattoos

By Cecillia Wong. -

Originating from Ancient India, Henna (also known as Mehndi) is a body art where decorative designs are drawn onto a person’s body using a paste created from the leaves of a henna plant. It is commonly used as an accessory on special occasions such as weddings and holidays. Some of the holidays celebrated with henna are Purim,  Diwali , Passover, and various saints’ days.   Where can you get henna tattoos? Henna has historically been used in the Arabian Peninsula, Indian Subcontinent, Southeast Asia, Carthage, and North Africa. There are independent henna artists in the United States. However, hiring a henna artist can cost you anywhere upwards of $75/hr. How will 3D printing affect henna printing? The application of henna is very demanding. It is traditionally applied by highly skilled artists with a steady hand as once the material is applied, it will stain the skin almost immediately. The tattoos can last up to three weeks without fading. It also relies on

Bioprinting: Why do we need it?

What is bioprinting and what is it used for? What is bioprinting? 3D bioprinting is a rapidly growing field, but what exactly does it entail? Much like a 3D printer, it leverages the concept of additive manufacturing to create layers of tissue-like structures often including cells. By using the same tools in 3D design and deposition, scientists can use bioprinting technology to create intricate and sophisticated structures needed to build tissues and organs. While the capabilities of bioprinting have not yet reached the level depicted by popular culture, we are on the brink of a bioprinting revolution and fully transplantable organs should be feasible within the next decade. The potential of 3D bioprinters is immeasurable, with promise in altering the very limits of the human lifespan itself. For those curious about this new technology, here are some basics of bioprinting. Technology: What is a bioprinter? A bioprinter works in a similar way as a 3D printer. It moves in the x, y a

My 3D printer can bioprint... right? NOT

Ear scaffold printed by r3bEL bioprinter Plastic widget printed by a typical 3D printer By Mayasari Lim, Ph.D. When the r3bEL from SE3D is on display at CES , NSTA or other educational events focused on STEM, the first impression is that it’s another 3D printer like those manufactured by MakerBot or Dremel . As you move in closer and notice that there is no spool for filament, one becomes a bit puzzled and asks the question, “Dr. Lim, this is a 3D printer right?” In some ways but its features and applications are very different than the 3D printers most educators are familiar with. While the r3bEL may have the basic physical structure and platform resembling a 3D printer, it has certain distinct features that cannot be produced in 3D printers typically found in schools. The r3bEL is actually classified as a “bioprinter” for the following; F ACT #1 – It does not print plastic! Most desktop 3D printers like MakerBot are based on fused deposition
