Background: The 3D printer came in the 1980s. Since then, its innovation has allowed its use in many areas suchas: engineering, art, industry, education and medicine. The scanning and 3D printing of anatomical components hasgained relevance in recent years due to the advancement in the technology of scanning equipment and 3D printers.Since 3D models are useful in several areas of health, the present study aimed to standardize the three-dimensionalscanning and printing of the coxal bones and the long ones of the pelvic limbs of dogs. The aim was to build a dynamic3D digital collection, as well as generate templates for didactic use, or for use in both prostheses and orthopedicsurgical planning.Materials, Methods & Results: In present study, a 3D macroscopic scanning system, Creaform brand Go! Scan 3D modeland a Fused Deposition Modeling (FDM) 3D Printer (Stratasys Mojo Printer) were used. After proper maceration of thebones under study, these were scanned, edited, printed and washed. Replicas of the coxal and left femur, tibia and fibulabones were obtained, as well as generating digital files that can be converted into PDFs.Discussion: From the models scanned in 3D, a dynamic digital collection was built for anatomical study, which can beused to complement practical classes. The creation of a collection of anatomical pieces printed in 3D can reduce the useof cadavers in class. The printed material can also be used as a template for orthopedic surgical planning or serve as abasis for the manufacture of prostheses, contributing to the improvement of the surgical and orthopedic clinic. 3D printing can be successfully used in veterinary medicine through the production of prostheses for injured animals as well asfor surgical planning of orthopedic procedures. The scan allows the generation of a collection for bioprinting, just as thetomography does in medical practice. Such steps are important in the final generation of parts to be used for both...(AU)
