This paper provides a systematic review of over 350 publications that document specific medical device examples in which the design and manufacturing relied on additive manufacturing processes (more popularly referred to as “3d Printing”). Existing reviews on 3d printing for medical device design focus on the range of clinical applications and potential uses for this technology. However, existing work tends to omit key medical device development and regulatory requirements pertaining to the use of 3d printing for technology translation. These omissions often present a skewed view of each device’s potential for rapid translation to commercialization and common clinical practice. To fill gaps in existing literature, this review includes medical device journal articles and identifies each article’s country of origin, the product development stage in which 3d printing was used, and the device’s specific type and classification under the U.S. Food and Drug Administration. The findings from this systematic review provide a detailed international snapshot of current additive manufacturing research and its near term potential for changing clinical practice.

AbstractPhotopolymerization-based three-dimensional (3D) printing can enable customized manufacturing that is difficult to achieve through other traditional means. Nevertheless, it remains challenging to achieve efficient 3D printing due to the compromise between print speed and resolution. Herein, we report an efficient 3D printing approach based on the photooxidation of ketocoumarin that functions as the photosensitizer during photopolymerization, which can simultaneously deliver high print speed (5.1 cm h−1) and high print resolution (23 μm) on a common 3D printer. Mechanistically, the initiating radical and deethylated ketocoumarin are both generated upon visible light exposure, with the former giving rise to rapid photopolymerization and high print speed while the latter ensuring high print resolution by confining the light penetration. By comparison, the printed feature is hard to identify when the ketocoumarin encounters photoreduction due to the increased lateral photopolymerization. The proposed approach here provides a viable solution towards efficient additive manufacturing by controlling the photoreaction of photosensitizers during photopolymerization.

Objective: To determine the current applications of 3-dimensional (3D) printing in the care of patients with cleft lip and palate. We also reviewed 3D printing limitations, financial analysis, and future implications. Design: Retrospective systematic review. Methods: Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used by 3 independent reviewers. Articles were identified from Cochrane library, Ovid Medline, and Embase. Search terms included 3D printing, 3 dimensional printing, additive manufacturing, rapid prototyping, cleft lip, and cleft palate. Exclusion criteria included articles not in English, animal studies, reviews without original data, oral presentations, abstracts, opinion pieces, and articles without relevance to 3D printing or cleft lip and palate. Main Outcome Measures: Primary outcome measure was the purpose of 3D printing in the care of patients with cleft lip and palate. Secondary outcome measures were cost analysis and clinical outcomes. Results: Eight-four articles were identified, and 39 met inclusion/exclusion criteria. Eleven studies used 3D printing models for nasoalveolar molding. Patient-specific implants were developed via 3D printing in 6 articles. Surgical planning was conducted via 3D printing in 8 studies. Eight articles utilized 3D printing for anatomic models/educational purposes. 3-Dimensional printed models were used for surgical simulation/training in 6 articles. Bioprinting was utilized in 4 studies. Secondary outcome of cost was addressed in 8 articles. Conclusion: 3-Dimensional printing for the care of patients with cleft lip and palate has several applications. Potential advantages of utilizing this technology are demonstrated; however, literature is largely descriptive in nature with few clinical outcome measures. Future direction should be aimed at standardized reporting to include clinical outcomes, cost, material, printing method, and results.
