Nanoscale Printing• Jurgen Stampfl team

at TU Vienna

• Liquid resin hardened precisely by focal point of laser beam guided by mirrors

• Hardened polymer lines are few hundred nanometers wide

• Print speed of 5 meters/sec vs. mm/sec means 2 photon lithography can make larger objects

• Team working on bio-compatible resins for medical applications, such as scaffolds for cell growth

Printing Blood Vessels• Bioengineers from the U Penn use a 3D printer called a RepRap to

make templates of blood vessel networks out of sugar. Once the networks are encased in a block of cells, the sugar can be dissolved, leaving a functional vascular network behind.

• The printer builds the walls of a stabilizing mold. Then it then draws filaments across the mold, pulling the sugar at different speeds to achieve the desired thickness of what will become the blood vessels.

• After sugar hardens, they add liver cells suspended in a gel to the mold. The gel surrounds the filaments, encasing the blood vessel template. After the gel sets it can be removed from the mold with the template still inside.

• The block of gel is washed in water, dissolving the sugar inside. Liquid sugar flows out of the vessels it has created without harming the growing cells.

• Shaochen Chen team, UC San Diego

• Developed DOPsL - dynamic optical projection stereolithography

• Print hydrogels by photo-induced solidification. The process forms one layer of solid structure at a time, but in a continuous fashion.

• Mar 2012, Obama admin. launched a $1B investment in advanced manufacturing techs, including creating the National Additive Manufacturing Innovation Institute with $30 million in federal funding to focus on 3D printing.

Directed Assembly• DA - how to make particles assemble to form a broad

range of structures at given locations, such as electric or magnetic field

• Kathleen Stebe group, U Penn

• Surface tension for directed assembly

• Cylindrical particles of a common polymer, when placed on the surface of a thin film of water, the cylinders produce a saddle-shaped deformation: the water’s surface dips at each end of a particle and rises up along their sides

Graphene Replaces Traditional Silicon Substrates in Future Devices• Researchers at the Norwegian University of

Science and Technology (NTNU) have patented and are commercializing a method by which gallium arsenide (GaAs) nanowires are grown on graphene. 

The method, employs Molecular Beam Epitaxy (MBE) to grow the GaAs nanowires layer by layer.

Advanced Origami• Team from Aalto Univ.,

Finland and Univ. of Washington

• Breakthrough using deformation through stress-relaxation

• Phenomena observed in the natural world, from the curling of flowers to the opening of seed capsules

• Reactive ion etching and focused ion beam, can be used to induce stress at defined locations on very nanometer-sized polycrystalline metal films, ultimately enabling them to manipulate the films into the desired complex 3D geometries
