Assessing the utility of 3D printed models of Mullerian tract anomalies for clinical education.* 26	Impact of 3DP models on trainees’ understanding of Mullerian tract anomalies and assessment of the feasibility of producing such models.	Gynaecologists and general surgery trainees (exact number of participants not given).	3DP models were found to increase gynaecologists’ understanding of Mullerian tract anomalies and their confidence in surgery to correct them.	None reported.
Developing a 3D composite training model for cranial remodelling.13	Use of 3DP models at two annual practical courses to teach neurosurgical techniques (FOA and ES) for correction of craniosynostosis Surveys were given to attendees and non-attendees a year after the course.	33 students, resident, fellows and attending surgeons over 2 years.	Models were a valuable training tool for surgical techniques and improved understanding and preparedness to perform the procedures.	None reported.
