3D Printing Research: Liquid Droplets Lead Way to Drug Delivery
3D Printing Research: Liquid Droplets
3D printers don’t build only solid objects anymore. They also build liquid objects, thanks to a research team at the University of Oxford.
Microscopic water-filled, lipid-coated droplets pop from a printer’s nozzles and stick to one another to form patterned structures. The researchers envision the clusters’ use in future tissue engineering. They also demonstrate the construction of a flowerlike droplet network that curls into a sphere because of osmosis. This self-folding behavior, the research team contends, might be put to use in drug delivery systems someday.

Enterprise-Class 3D Printer Prices to Fall Below $2,000 by 2016
Enterprise-Class 3D Printer Prices to Drop Below $2,000 by 2016, Gartner Reports
In a new report. Gartner says early adopters of 3D printing technology will gain an innovation advantage over rivals.
3D printing is disrupting the design, prototyping and manufacturing processes in a wide range of industries, according to Gartner, Inc. Enterprises should start experimenting with 3D printing technology to improve traditional product design and prototyping, with the potential to create new product lines and markets. 3D printing will also become available to consumers via kiosks or print-shop-style services, creating new opportunities for retailers and other businesses.
“3D printing is a technology accelerating to mainstream adoption,” said Pete Basiliere, research director at Gartner. “It is a technology of great interest to the general media, with demonstrations on science shows, on gadget websites and in other areas. From descriptions of exciting current uses in medical, manufacturing and other industries to futuristic ideas — such as using 3D printers on asteroids and the moon to create parts for spacecraft and lunar bases — the hype leads many people to think the technology is some years away when it is available now and is affordable to most enterprises.”
The material science behind 3D printing processes and materials will continue to progress, and affordable 3D printers are lowering the cost of entry into manufacturing in the same way that e-commerce lowered the barriers to the sale of goods and services. As a result, the 3D printer market will continue moving from niche adoption to broad acceptance, driven by lower printer prices, the potential for cost and time savings, greater capabilities, and improved performance that drives benefits and markets.
“Businesses must continuously monitor advances to identify where improvements can be leveraged,” said Mr. Basiliere. “We see 3D printing as a tool for empowerment, already enabling life-changing parts and products to be built in struggling countries, helping rebuild crisis-hit areas and leading to the democratization of manufacturing.”
3D printing is already established in industries ranging from automotive manufacturing to consumer goods to the military, as well as the medical and pharmaceutical industries. Businesses can use 3D printing to design personalized products, components, working prototypes and architectural models to promote their brand and products in new and interactive ways. Indeed, there are opportunities to create entirely new product lines in which the finished 3D-printed product is what the consumer purchases.
3D printers are now priced so that any size business can invest in them and start experimenting with the myriad ways to monetize them. By 2016, enterprise-class 3D printers will be available for under $2,000. Early adopters can experiment with 3D printers with minimal risk of capital or time, possibly gaining an advantage in product design and time to market over their competition, as well as understanding the realistic material costs and time to build parts. Furthermore, enterprise uses for 3D printers have expanded as capabilities of 3D scanners and design tools have advanced, and as the commercial and open-source development of additional design software tools has made 3D printing more practical. Gartner believes that the commercial market for 3D print applications will continue expanding into architectural, engineering, geospatial and medical uses, as well as short-run manufacturing.
Major multinational retailers have the means to market the technology to consumers and generate revenue by selling printers and supplies, as well as from sales of individual 3D-printed pieces. One vision is for the retailers to not only sell the printers, but also offer a service bureau that prints custom items or personalized variations on stock items, a key consumer trend.
Another possibility is for roving display vans to visit the retailer’s stores. Customers would visit these self-contained vans parked in front of the store that contain two or three operating printers and watch parts being made (including possibly their own personalized 3D item). Alternatively, the consumer could order the custom or personalized part to be made while they are shopping, or to be available for pickup the next day.

Nature’s 3D Printing: Using E. Coli Bacteria to Grow Objects
The field of synthetic biology offers us state-of-the-art results like biofuel, but researchers are looking to push the envelope and develop a technique that could be Nature’s version of 3D printing.
Designers at IDEO have teamed up with scientists at the Lim Lab at the University of California, San Francisco to envision a “provocation” (that’s designer-ese for thought experiment) in which they explore the possibilities of exploiting known properties of microorganisms to literally “grow” the products we use every day.
In layman’s terms, researchers are exploring ways to train bacteria to grow into shapes when exposed to light. Perhaps one training could result in a coffee cup while another results in a functional motor gear.
In their first visual exploration of this possibility, they decided to expand on an already-demonstrated property of certain E. coli bacteria. These bugs were genetically engineered to be responsive to light, creating so-called “bacterial photographs.”
From there, Will Carey and Adam Reineck of IDEO teamed up with Reid Williams, a Ph.D. candidate at UCSF, to imagine a photo-sensitive microorganism that would have its light-sensitive switch linked to a different property–say, the production of a hard shell.
The result could be a tough and durable everyday object made out of cells encased in cellulose–the stuff in plants–or chitin, which is the major component of lobster shells.
It’s important to note that at this stage, this process is still entirely conceptual. But it is based on real science, and that’s the whole point: design provocations like these help people think outside the mental boxes we’ve all been put in by our limited knowledge of what’s happening at the frontiers of science.

Researchers Use Nano-Scale 3D Printing to Combat Prostate Cancer
Advanced nano-scale 3D printing techniques are being used to develop new drugs for prostate cancer and other applications. Parabon NanoLabs in Reston, Virginia is conducting this groundbreaking research with support from the National Science Foundation and other grants.
Using a simple “drag-and-drop” computer interface and DNA self-assembly techniques, researchers have developed a new approach for drug development that could drastically reduce the time required to create and test medications.
“We can now ‘print,’ molecule by molecule, exactly the compound that we want,” says Steven Armentrout, the principal investigator on the NSF grants and co-developer of Parabon’s technology. “What differentiates our nanotechnology from others is our ability to rapidly, and precisely, specify the placement of every atom in a compound that we design.”
The new technology is called the Parabon Essemblix™ Drug Development Platform, and it combines their computer-aided design (CAD) software called inSēquio™ with nanoscale fabrication technology.
Scientists work within inSēquio™ to design molecular pieces with specific, functional components. The software then optimizes the design using the Parabon Computation Grid, a cloud supercomputing platform that uses proprietary algorithms to search for sets of DNA sequences that can self-assemble those components.

Printed Optics: Disney Research 3D Printing to Create Future of Toys
Collaborators from Disney Research and Carnegie Mellon University are using 3D printing to create the future of interactive toys they call “Printed Optics.” Excerpts from a research paper are included below.
We present an approach to 3D printing custom optical elements for interactive devices labelled Printed Optics. Printed Optics enable sensing, display, and illumination elements to be directly embedded in the casing or mechanical structure of an interactive device. Using these elements, unique display surfaces, novel illumination techniques, custom optical sensors, and embedded optoelectronic components can be digitally fabricated for rapid, high fidelity, highly customized interactive devices. Printed Optics is part of our long term vision for interactive devices that are 3D printed in their entirety. In this paper we explore the possibilities for this vision afforded by fabrication of custom optical elements using today’s 3D printing technology.Printed Optics is a new approach to creating custom optical elements for interactive devices using 3D printing. Printed Optics enable sensing, display, and illumination elements to be directly embedded in the body of an interactive device. Using these elements, unique display surfaces, novel illumination techniques, custom optical sensors, and robust embedded components can be digitally fabricated for rapid, high fidelity, customized interactive devices.
3D printing allows digital geometry to be rapidly fabricated into physical form with micron accuracy. Usable optical elements can be designed and simulated in software, then 3D printed from transparent material with surprising ease and affordability.
But Disney’s vision is much grander. Watch the video below.
