Abstract:Diplomska naloga se je osredotočala na načrtovanje 3D tiskane podkolenske proteze za izboljšan prenos obremenitev na ležišče. Raziskane in razvite so bile različne konstrukcijske rešitve za distalni del protetičnega ležišča, ki bi izboljšale trdnost 3D tiskanih protez. Cilj je bil porazdeliti obremenitve na več slojev 3D tiska z uporabo cenovno dostopnih tehnologij, kot je tehnologija ciljnega nalaganja slojev (ang. Fused Filament Fabrication, krajše FFF) in materiala poliaktične kisline (ang. polylactic acid, krajše PLA). Naloga je vključevala teoretične osnove protetike spodnjih okončin, 3D tiska v protetiki in numeričnih metod. Razvitih je bilo več konceptnih in variantnih rešitev, ki so nato bile predelane v konstrukcijske modele. Pet modelov je bilo nato analiziranih z numeričnimi metodami. Analize so pokazale, da je bil model z vstavljenimi karbonskimi palicami najbolj učinkovit pri zmanjševanju napetosti na kritičnih mestih ležišča. Rezultati so pokazali, da je mogoče z uporabo tehnologije FFF doseči pomembne izboljšave pri izdelavi podkolenskih protez, vendar so potrebne nadaljnje raziskave in eksperimentalni testi za optimizacijo in praktično uporabo teh rešitev.

Title:Developing a 3d printed below-knee prosthesis to improve load transfer to the socket
Abstract:The research focused on developing a 3D-printed below-knee prosthesis to improve load transfer to the socket. Various structural solutions for the distal part of the prosthetic socket were investigated to strengthen 3D-printed prostheses. The aim was to distribute loads across multiple layers of 3D-printed sockets using cost-effective methods such as Fused Filament Fabrication (FFF) and PLA material. The study encompassed theoretical foundations of lower limb prosthetics, 3D printing in prosthetics, and numerical methods. Multiple conceptual and variant solutions were developed and transformed into structural models. Numerical methods were used to analyze five models, with the results indicating that the model with inserted carbon rods effectively reduced stress at critical points of the socket. The study concluded that significant advancements in manufacturing below-knee prostheses could be made using FFF technology, although further research and experimental tests are necessary to optimize and implement these solutions.
