3D-printing a new lifelike liver tissue for drug screening

Could let pharmaceutical companies quickly do pilot studies on new drugs
February 15, 2016

Biomimetic-3D-printed-liver-tissue-ft

University of California, San Diego researchers have 3D-printed a tissue that closely mimics the human liver’s sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling and could help pharmaceutical companies save time and money when developing new drugs, according to the researchers.

The liver plays a critical role in how the body metabolizes drugs and produces key proteins, so liver… read more

3D-printing a structure with active chemistry

Forget labs --- now you can simply print objects in your kitchen that create cool chemical reactions (attention: CIA and Homeland Security)
April 4, 2016

Flashforge Creator ft

Researchers at American University have demonstrated the first use of commercial 3D printers to create a structure with active chemistry — in this case, a structure that acts to mitigate pollution.

The researchers added titanium dioxide nanoparticles to standard ABS filament material (used in 3D printers) and extruded a filament that they then used to print a small, sponge-like plastic object on a low-cost Flashforge Creator… read more

UC Berkeley engineers, in collaboration with colleagues at Taiwan’s National Chiao Tung University, have developed a 3D printing process for creating basic electronic components, such as resistors, inductors, capacitors, and integrated wireless electrical sensing systems.

As a test, they printed a wireless “smart cap” for a milk carton that detected signs of spoilage using embedded sensors.

The findings were published Monday, July 20, in… read more

3D-printing human embryonic stem cells for drug testing, future replacement of human organs

New 3D printing process is first to print the more delicate (and more useful) hESCs
February 6, 2013

3D printing with embryonic stem cells (credit: )

A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.

The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more

3D-printing miniaturized medical implants, compact electronics, tiny robots, and more

June 24, 2013

For the first time, a research team from the Wyss Institute at Harvard University and the University of Illinois at Urbana-Champaign demonstrated the ability to 3D-print a battery. This image shows the interlaced stack of electrodes that were printed layer by layer to create the working anode and cathode of a microbattery. [Ke Sun, Teng-Sing Wei, Jennifer Lewis, Shen J.

A team based at Harvard University and the University of Illinois at Urbana-Champaign has printed precisely interlaced stacks of tiny battery electrodes, each less than the width of a human hair

3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have… read more

In another leap for 3D printing, researchers at the USC Viterbi School of Engineering have developed a faster 3D printing process that allows for 3D-printing multi-material objects in minutes instead of hours.

Fabrication time and the complexity of multi-material objects have been a hurdle to widespread use of 3D printing.

Speeding up printing

USC Viterbi researchers developed improved mask-image-projection-based stereolithography (MIP-SL) to drastically… read more

A common vitamin — riboflavin (vitamin B2) — has made it possible to 3D-print non-toxic medical implants, researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered.

“This opens the door to a much wider range of biocompatible implant materials, which can be used to develop customized implant designs using 3-D printing technology,” says Dr.… read more

3D-printing objects containing multiple metals and alloys

July 29, 2014

This is a prototype of a mirror mount that scientists made using a new 3-D printing technique. The part at the top near the glass mirror is made of a metal with low thermal expansion, so that it won't shrink in space as much as most metals do. Using this kind of metal therefore prevents stress in the epoxy adhesive between the mirror and the metal. The bottom part of this mount is stainless steel, and could be connected to a stainless steel component of a spacecraft. (Credit: NASA-JPL/Caltech)

Researchers at NASA‘s Jet Propulsion Laboratory (JPL), California Institute of Technology, and Pennsylvania State University have developed a 3D printing process that transitions from one metal or alloy to another in a single object.

For example, they created a prototype of an improved telescope mirror mount. The part at the top near the glass mirror is made of a metal with low… read more

Schematic of printing in aqueous solution. Aqueous droplets are ejected into a<br /> drop of oil suspended in bulk aqueous solution.

A custom-built programmable 3D printer can create materials with some the properties of living tissues, Oxford University scientists have demonstrated.

The new type of material consists of tens of thousands of picoliter connected water droplets encapsulated within lipid films, which can perform some of the functions of the cells inside our bodies.

These printed “droplet networks” might be interfaced with tissues, used as tissue… read more

3M and IBM to develop new types of adhesives to create 3D semiconductors

September 8, 2011
3D chips

3M and IBM announced that the two companies plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon “towers,” making it possible to build, for the first time, commercial microprocessors composed of layers of up to 100 separate chips.

Such stacking would allow for dramatically higher levels of integration for information technology and consumer electronics applications. Processors could… read more

Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong (UOW) are developing 3-D printed materials that morph into new structures under the influence of external stimuli such as water or heat. They refer to this process as “4-D printing,” where the fourth dimension is time.

The researchers are currently exploring a use in manufacturing a valve that actuates… read more
