"Through history, numerous art, religious and every-day objects were carved from ivory because of its aesthetic appearance, convenient workability and its durability. Since the ivory trading ban was passed in 1989, many natural and synthetic materials were introduced as a replacement, but these are typically only available in bulk. …The newly developed substitute material called "Digory" is processible with an additive manufacturing technique that derived from stereolithography."

"Additive manufacturing shows great promise for making things in a way that more closely resembles natural form, but some of the below strategies are worth investigating to reduce or eliminate toxicity and to make more functional products.".

"If the ultimate prize in additive manufacturing is finding a universal kit of parts, then recent nature-inspired developments in small molecule chemistry may have brought us closer to this world of the future."

Researchers at the University of California, Riverside and Purdue University have used the mantis shrimp as inspiration for a new 3D printed material. The crustacean’s club-like appendage, used to beat prey, consists of an unusual herringbone pattern, which the researchers synthetically replicated.

"As additive manufacturing, or 3D printing, becomes more and more sophisticated and capable of direct production in some applications, a class of software is emerging that exploits the capability of AM technology to produce objects in a highly freeform manner. Engineering and manufacturing software giant Autodesk refers to this emerging model as goal-directed design (GDD). Autodesk is building a GDD CAD system called Dreamcatcher, now under development at its research lab while deployed in beta form to a number of the firm's customers.[...] Rather than defining a part in great detail from the top down, in bio-inspired computer-aided design, the user gives the software a set of fundamental rules and lets it seek out the optimal solution to a problem. Autodesk’s GDD system turns CAD on its head in a similar way; as opposed to a starting point of inputting the desired geometry, Dreamcatcher's bio-inspired algorithms generate the optimal design solution, employing whatever geometry solves the problem."
