Additive manufacturing is an advanced manufacturing manner that seems like the industrial revolution. It has the inborn benefit of producing complex formations, which are distinct from traditional machining technology. Its manufacturing strategy is flexible, including a wide range of materials, and its manufacturing cycle is short. Additive manufacturing techniques are progressively used in bone research and orthopedic operation as more innovative materials are developed. This Review lists the recent research results, analyzes the strengths and weaknesses of diverse three-dimensional printing strategies in orthopedics, and sums up the use of varying 3D printing strategies in surgical guides, surgical implants, surgical predictive models, and bone tissue engineering. Moreover, various postprocessing methods for additive manufacturing for orthopedics are described.

“…These characteristics include apparent density in Houns eld Units (HU), potential artifact generation, and ultrasonic transmission. In addition, many of these resins have biocompatible properties and are widely used throughout dentistry and medicine as implants, hardware, or as educational models (11)(12)(13)(14)(15). Access to data on the imaging traits of Formlabs SLA materials is essential for the creation of realistic phantom models which can aid in medical education and intervention planning, preparation, and execution.…”

“…Successful 3D models and devices should accurately characterize human tissue both anatomically and radiographically (3,5,(14)(15). Diagnostic and interventional radiologists have a unique role in the successful implementation of 3D printing into clinical practice, as the process of capturing and interpreting precise anatomical data is compatible with the daily work ow of these specialties.…”

Background: Additive manufacturing describes the process of creating and printing three-dimensional products. In medicine, stereolithography remains one of the most commonly used additive manufacturing techniques. At present, few studies have sought to quantify the imaging properties of stereolithography resins, which would allow for standardization and streamlining of medical research in additive manufacturing. The aim of this study is to quantify and catalog imaging properties of commercially available FormLabs stereolithography resins via computer tomography, magnetic resonance imaging, and ultrasound. Methods: Fourteen unique stereolithography resins offered by Formlabs (Somerset, MA) were selected based on their clinical utility. Each resin was subject to a tri-modality investigation through computer tomography, magnetic resonance imaging, and ultrasound imaging. Image analysis was performed by two separate board-certified radiologists using the picture archiving and communication system. Results of this analysis were aggregated and organized onto data tables. Results: Of the fourteen resins evaluated by computed tomography, twelve were found to have radiological properties that were within one standard deviation (σ) of a known type of body tissue, in Hounsfield Units. When the same fourteen resins were evaluated by magnetic resonance imaging, little variability was observed between each resin in image intensity. Of the fourteen resins evaluated through ultrasound, imaging revealed little variability with no significant points of comparison with human tissue. Conclusion: Our investigation confirms that computed tomography is an ideal method for comparing imaging properties of stereolithography resins with those of human tissue. A comprehensive catalog of imaging properties for stereolithography resins allows clinical investigators to standardize future research studies, decreasing inter-observer variability and improving research outcomes for new devices and phantom models in medicine.

“…Radiology is well-poised to integrate 3D printing within simulation training. Prototypes, ranging from the lumbar spine to complex vasculature [48][49][50][51], have successfully been printed and can be modified for simulation purposes. While the role of three-dimensional printing for trainee education has been documented in other procedural specialties, there is a lack of knowledge about the role of 3D printing for trainee education within IR.…”

Rationale and objectives Three-dimensional (3D) printing has been utilized as a means of producing high-quality simulation models for trainees in procedure-intensive or surgical subspecialties. However, less is known about its role for trainee education within interventional radiology (IR). Thus, the purpose of this review was to assess the state of current literature regarding the use of 3D printed simulation models in IR procedural simulation experiences. Materials and methods A literature query was conducted through April 2020 for articles discussing three-dimensional printing for simulations in PubMed, Embase, CINAHL, Web of Science, and the Cochrane library databases using key terms relating to 3D printing, radiology, simulation, training, and interventional radiology. Results We identified a scarcity of published sources, 4 total articles, that appraised the use of three-dimensional printing for simulation training in IR. While trainee feedback is generally supportive of the use of three-dimensional printing within the field, current applications utilizing 3D printed models are heterogeneous, reflecting a lack of best practices standards in the realm of medical education. Conclusions Presently available literature endorses the use of three-dimensional printing within interventional radiology as a teaching tool. Literature documenting the benefits of 3D printed models for IR simulation has the potential to expand within the field, as it offers a straightforward, sustainable, and reproducible means for hands-on training that ought to be standardized.
