On the optimization of low-cost FDM 3D printers for accurate replication of patient-specific abdominal aortic aneurysm geometry

Abstract: BackgroundThere is a potential for direct model manufacturing of abdominal aortic aneurysm (AAA) using 3D printing technique for generating flexible semi-transparent prototypes. A patient-specific AAA model was manufactured using fused deposition modelling (FDM) 3D printing technology. A flexible, semi-transparent thermoplastic polyurethane (TPU), called Cheetah Water (produced by Ninjatek, USA), was used as the flexible, transparent material for model manufacture with a hydrophilic support structure 3D printe… Show more

“…The machines consume inexpensive thermoplastics, retailing from $30–80 for a kilogram, which equates to $10–20 per AAA model. Although transparent thermoplastics exist, the resolution of FDM technology and the layered deposition results in at best a translucent end product, as reported by Chung et al ( 32 ). Depending on the size of the AAA being printed, FDM machines require 24–48 h to 3D print the final product, with additional time required for support structures to be manually removed.…”

“…Atalay et al 15 used FDM printed models of the pelvicalyceal system when planning PCNL surgery as only one colour was needed for this purpose. Chung et al 16 have similarly aimed to reduce costs in 3D printed abdominal aortic aneurysm (AAA) models, using FDM printers to create models for as cheap as USD 6. We have also published a case of ureteric stent encrustation which was printed on a low-cost FDM printer 17 .…”

“…In particular, anatomically accurate internal organ images, obtained with X-rays, computed tomography, dual-energy imaging, cone beam computed tomography, or digital tomosynthesis, can be printed in order to produce modular anthropomorphic mannequins [ 98 ]. This allow for replicating and studying a wide range of pathologies [ 99 , 100 , 101 , 102 , 103 ], as well as for reducing the ethical concerns [ 100 , 102 , 103 ] relative to the use of cadaveric and animal models for education, surgical planning, and training purposes.…”
