Abstract
Laser Engineering Net Shaping (LENS), which is one of the 3DP techniques, allows for both, the fabrication and the modification of surface layer of the product previously prepared. In the current work, using LENS technique, highly developed bioactive layers, were prepared on the surface of the hip prosthesis. Both, fabricated layers and hip prosthesis, were fabricated from Ti-6Al-4V alloy. The tests were carried out using Simulated Body Fluid (SBF) solution, having all the necessary components on the inorganic human blood plasma. Scanning Electron Microscopy (SEM) showed the nucleation of calcium phosphates even after 2 days of immersion. Based on the results obtained in SEM and EDX tests, it can be claimed that Ti-6Al-4V layers manufactured using LENS technique exhibit high bioactivity in in-vitro, in the SBF solution.

Summary
Kształtowanie przyrostowe LENS (Laser Engineering Net Shaping), będące jedną z technik druku 3D, umożliwia zarówno wytwarzanie, jak i modyfikacje samej warstwy wierzchniej wytworzonego wcześniej produktu. Na podstawie uzyskanych wyników podczas badań z użyciem SEM i EDX (Energy-Dispersive X-ray Spectroscopy) można stwierdzić, że wytworzone techniką LENS warstwy ze stopu Ti-6Al-4V wykazują wysoką bioaktywność w warunkach badań in-vitro w SBF.

Jedną z technik druku 3D, umożliwiającą modyfikację powierzchni implantów, jest metoda LENS (Laser Engineering Net Shaping). Poprzez testy in-vitro w roztworze SBF, podczas których powstają fosforany wapnia, w tym hydroksyapatyt, będący głównym składnikiem ludzkiej kości Możliwość wytworzenia trwałego połączenia na granicy implant–kość można sprawdzić przed badaniami klinicznymi, np. poprzez testy in-vitro w roztworze SBF, podczas których powstają fosforany wapnia, w tym hydroksyapatyt, będący głównym składnikiem ludzkiej kości
