The US Department of Energy’s Ames Laboratory has developed a 3D printing process that creates a chemically active catalytic object in a single step, opening the door to more efficient ways to produce catalysts for complex chemical reactions in a wide scope of industries.
While 3D printing has found applications in many areas, its use as a way to control chemical reactions or catalysis is relatively new. Current production of 3D catalysts typically involves various methods of depositing the chemically active agents onto pre-printed structures.
The Ames Laboratory method combines the structure with the chemistry in only one step using inexpensive commercial 3D printers. The structures are designed in a computer and built directly by shining a laser through a bath of customized resins that polymerize and harden layer-by-layer. The final product that emerges has catalytic properties already intrinsic to the object.
