Introduction: A cross-sectional survey was conducted to collect data from Australian and New Zealand radiotherapy departments to establish a baseline for 3D printer ownership and 3D printed product use. Methods: All Antipodean departments were contacted by phone to establish 3D printed product use and determine the most appropriate person to answer the survey. An email containing a Microsoft Forms link to a survey was sent to the knowledge expert in eligible departments. The survey contained 47 questions in relation to how 3D printed products were being utilised and specific questions regarding ownership of a 3D printer. The data was uploaded to Microsoft Excel and descriptive statistics were performed. Results: 112 departments were initially contacted, with 22.3% reporting 3D printer ownership, and 33.3% of Australian departments choosing to outsource 3D printed product. The primary use of 3D printers was bolus production (60.9%). Public departments represent 84% of printer ownership, while private departments are the greatest users of outsourced 3D printed product (91.4%). 3D Slicer is the most common software used for digital imaging and communications in medicine file conversion (42.3%), while polylactic acid and acrylonitrile butadiene styrene are the most common filaments in use, 46% and 14%, respectively. Conclusion: This research established a baseline for 3D printer and product use within Australian and New Zealand radiotherapy departments. The knowledge gained from this analysis can inform departments in the decision-making process for future 3D printer acquisition and implementation.
