Table 4 Technical components used to classify 3D printing levels of complexity. Three-hundred thirty-five minutes was the mean time spent by the non provider (to include the engineer and other non-physician 3D printing specialists) as reported in the initial data analysis [7] of the RSNA-ACR 3D printing registry [8]. Digital modification was divided into two groups as previously described [15]
Parameter (variable) | Classification |
|---|---|
3D Printing Technology | Material Extrusion, Vat Polymerization, Material Jetting |
Desktop Machine | Yes, No |
Expected non provider effort* |  < 335 min, 335 min or longer [7] |
Number of parts | 1–2, 3–5, 6 +  |
Substantial digital modification [15] | Major, Minor |
Biocompatibility | Yes, No |
Sterilization | Yes, No |
