We have developed a 3D-printed physical model, called Peppytides (http://www.peppytides.org), that can be folded accurately into various secondary and tertiary structures and motifs of proteins. 

QuezyLab will be manufacturing dimensionally-accurate, foldable 3D-printed physical models of polypeptide chain with side chains. As a first step, we are distributing several of these models to educational venues, starting with schools and colleges in the bay area. 

Please contact us at sales(at)quezylab.com for a quote (or preorder).

We have already delivered lectures at several schools and we got immense response and interest. We are looking for academic collaborators to develop new curriculum using 3D printing techniques. If interested, please contact us at outreach(at)quezylab.com
