3D Molecular Designs, LLC produces accurate, three-dimensional physical models of proteins and other molecular structures using rapid prototyping technology. Models are based on x,y,z coordinates obtained from pdb files of known structures. Five different rapid prototyping technologies are used to produce models in a variety of different formats. The company provides models for both research and education purposes. Molecule models include enzymes, DNA, mRNA, and custom models. The company was founded by Tim Herman,after founding the Center for BioMolecular Modeling at the Milwaukee School of Engineering (MSOE). Michael Patrick, Ph.D., of the University of Wisconsin - Madison, was co-founder.
