Concept clusters within 3D printing literature arranged as individual MeSH categories and clustered by distance within the literature. Colors correspond to major MeSH categories: red represents “Diseases”, green corresponds to “Chemicals and Drugs” and blue represents “Analytical, Diagnostic and Therapeutic Techniques and Equipment”. Circle size represents the relative number of papers annotated with a particular MeSH term, while distance reflects concept proximity
