The registry defines a print as a specific set of parts printed on a particular machine at a particular scale using a particular material.  A print may consist of one or more copies; multiple copies do not constitute additional prints.  If the parts, printer, scale or material are changed, then this constitutes a separate print.  The registry requires description of at least one print, which is considered the “primary print.”  If a second print is created (again, consisting of either a different set of parts, a different printer and/or a different material), then this is considered the “secondary print.”  For example, in a cardiac case it may be necessary to print two different physical models: a myocardial model represented by one set of parts, as well as a blood pool model represented by certain other parts.  On the other hand, it will often be the case that only a single print will be produced.  If no secondary print is created, then the secondary print fields must be left blank.
