3D Printing Analysis by Powder Bed Printer (PBP) of a Thoracic Aorta Under Simufact Additive

Abstract

In recent decades, vascular surgery has seen the arrival of endovascular techniques for the treatment of vascular diseases such as aortic diseases (aneurysms, dissections, and atherosclerosis). The 3D printing process by addition of material gives an effector of choice to the digital chain, opening the way to the manufacture of shapes and complex geometries, impossible to achieve before with conventional methods. This chapter focuses on the bio-design study of the thoracic aorta in adults. A bio-design protocol was established based on medical imaging, extraction of the shape, and finally, the 3D modeling of the aorta; secondly, a bio-printing method based on 3D printing that could serve as regenerative medicine has been proposed. A simulation of the bio-printing process was carried out under the software Simufact Additive whose purpose is to predict the distortion and residual stress of the printed model. The binder injection printing technique in a Powder Bed Printer (PBP) bed is used. The results obtained are very acceptable compared with the results of the error elements found.

3D and 4D Printing as Integrated Manufacturing Methods of Industry 4.0

“…Due to the ease of removing unbound powder with an air pistol after solidification, PBP does not require support structures. Several print heads combined with colored binders provide full-color printing (Ameddah and Mazouz, 2021;Xu et al, 2021).…”
