Perspectives on medical 3D printing at the point-of-care from the new European 3D Printing Special Interest Group.

This editorial presents the vision for the newly formed (2022) European 3D Special Interest Group (EU3DSIG) in the landscape of medical 3D printing. There are four areas of work identified by the EU3DSIG in the current landscape, namely: 1) creating and fostering communication channels among researches, clinicians and industry, 2) generating awareness of hospitals point-of-care 3D technologies; 3) knowledge sharing and education; 4) regulation, registry and reimbursement models.

3D surgical planning of pediatric tumors: a review.

BACKGROUND: 3D surgical planning for the treatment of tumors in pediatrics using different neuroimaging methods is witnessing an accelerating and dynamic development. Until now, there have been many reports on the use of 3D printing techniques in different aspects of medical practice. Pediatric tumors mainly in the abdomen are among the most medical specialties that benefit from using this technique. The purpose of the current study is to review published literature regarding 3D surgical planning and its applications in the treatment of pediatric tumors and present challenges facing these techniques. MATERIALS AND METHODS: A completed review of the available literature was performed, effect sizes from published studies were investigated, and results are presented concerning the use of 3D surgical planning in the management of pediatric tumors, most of which are abdominal. RESULTS: According to the reviewed literature, our study comes to the point that 3D printing is a valuable technique for planning surgery for pediatric tumors in heart, brain, abdomen and bone. MRI and CT are the most common used techniques for preparing 3D printing models, as indicated by the reviewed reports. The reported studies have indicated that 3D printing allows the understanding of the anatomy of complex tumor cases, the simulation using surgical instruments, and medical and family education. The materials, 3D printing techniques and costs to be used depend on the application. CONCLUSION: This technology can be applied in clinical practice with a wide spectrum, using various tools and a range of available 3D printing methods. Incorporating 3D printing into an effective application can be a gratifying process with the use of a multidisciplinary team and rapid advances, so more experience would be needed with this technique to show a clinical gain.
