3-D Printing Gets Ahead: How Does a Printer Make a Fossil?

3-D printers can create models and prototypes, replicas of your head, even living tissues—and at Lehman College, they reproduce and reconstruct ancient fossils

3D VIRTUAL AND SOLID VISUALIZATION LAB:

Lehman College graduate student Claudia Astorino operates the Objet Eden260 3-D printer [ right ]. The cartridges of printing resin (a material that will harden into a rigid blue plastic-like material) and support material, which together form the basis of the printed products, sit on the table behind the printer, and the beige box at left houses a water jet used to clean support material off products when they first emerge from the printer....[More]

VIRTUAL REALITY:

The tray shown on the left monitor is a digital representation of a physical tray, located in the body of the 3-D printer. Meanwhile, the monitor on the right displays data about the printer, such as whether it needs a fresh printing resin cartridge....[More]

CHOMPING AT THE BIT:

Open a computer file, and this digital mandible appears on the 3-D printer tray at the Lehman College 3D Virtual and Solid Visualization Lab. A user can rotate, move and blow up or shrink down a jawbone, for instance, until satisfied that it's ready to print....[More]

BELLY OF THE BEAST:

BELLY OF THE BEAST:

The wire-covered printhead at left moves back and forth over the printer tray at center, depositing resin layer by layer to build up a replica of the digital bone....[More]

Before fossil replica printing begins at the lab, a clear window on the printer's front must be closed to prevent dust and other contaminants from entering the chamber that houses the printhead.

CLEANING UP:

CLEANING UP:

When a fossil model emerges from the lab printer, the product is covered with a yellowish, semitransparent support material that will crumble off under the pressure of a water jet....[More]

ACCIDENTAL MUTANTS:

ACCIDENTAL MUTANTS:

Sometimes, an error in the printer leads to models with filled-in eye sockets or other "mutations," earning the skewed replica a place on this shelf of deformed skulls.

GETTING AHEAD:

If all goes well, "support material" falls away to reveal the model of a long-lost primate's bones. So researchers have literally printed out a skull—albeit made of simulated plastic, not bone....[More]

    I've been hearing about the variety of different materials 3D (and 2D) printers could handle. I'd like to know more about what materials are possible, especially such as printed solar cells that I've heard about, and what complications might arise with each.

    The next step in Rapid Prototyping of Tissue Engineering is using Fractal Trigeometry for designing Artificial Organs.

    I wrote about this a few years back, when I talked to professors at Ramapo College: http://www.scribd.com/doc/45338737/Jumping-Off-the-Page-Engineering-Technology-story-about-3D-printing

    It's an exciting field. I am glad to see it take off.
