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

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

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
