A synergistic approach to the design, fabrication and evaluation of 3D printed micro and nano featured scaffolds for vascularized bone tissue repair

Holmes B., Bulusu K., Plesniak M., Zhang L.G., Nanochon LLC, George Washington University, US

In recent years, 3D printing has become a popular and widely investigated method for the fabrication of large bone implants. 3D printed bone constructs, devices and treatments hold great potential to repair traumatic and chronic [...]

Customized Manufacture of Protective Headgear for Primary Prevention of Fall Related Traumatic Brain Injuries

Ferguson J., Caccese V., Castle S., University of Maine, US

Alba-Technic, LLC and the University of Maine are developing an automated small batch manufacturing system that streamlines both the customization and manufacture of a protective headgear designed for aesthetic appeal and comfort by using advanced [...]

3D printing: How emerging materials, applications, and business models will disrupt manufacturing and enhance future innovation

Vicari A.C., Lux Research, US

From personalized medicine to personal drones, 3D printing – the additive manufacturing of objects by depositing and patterning successive layers of material – has been touted as an enabling platform for many compelling applications. Among [...]

Three-Dimensional Bioprinted Biomimetic Nanocomposite Scaffolds for Osteochondral Regeneration

Castro N.J., Zhang L.G., The George Washington University, US

The current work focused on the manufacture of a three-dimensional biphasic nanocomposite scaffold for osteochondral regeneration. Extrusion-based 3D printing in combination with ultraviolet light induced photocrosslinking allowed for good integration of two disparate polymeric materials [...]

Enhanced Mechanical and Cytocompatibility Properties of Novel 3D Printed Osteochondral Scaffolds

Holmes B., Zhang LG., The George Washington University, US

A series of novel 3D osteochondral computer aided models were designed including a homogenous cross-hatched structure, a bi-phasic structure consisting of a cross hatched pattern and an intersecting rings structure, and a biphasic “key” model [...]

Superhydrophobic 3D Printed Surfaces by Dip-Coating

Milionis A., Loth E., Bayer I.S., University of Virginia, US

Here we demonstrate a technique to fabricate three-dimensional superhydrophobic patterns. First a three-dimensional pattern was designed by 3D printing using acrylonitrile butadiene styrene (ABS) as printing material. A linear printing algorithm is followed for the [...]

Superhydrophobic and Superhydrophilic Surfaces

Herzog M.B., Johnston J.H., Franzreb M., Victoria University of Wellington, NZ

A new generation of materials possessing a wide range of possible consumer applications such as water harvesting, stain resistant self-cleaning and water-repellent breathable surfaces are being fabricated. Based on nature’s example of the stenocara beetle, [...]

Additive Manufacturing (AM) of Quantum Dot Nano-Inks

Ivanova O.S., Elliott A., Campbell T.A., Williams C.B., Virginia Tech, US

Additive Manufacturing (AM) pertains to technologies that fabricate 3D artifacts through the successive addition of 2D cross-sectional layers. Due to this layer-by-layer fabrication process, AM allows a designer to create geometrically complex artifacts with designed [...]
