prusaprinters

<p>This is a 3D printable prosthetic leg we have provided for Tabara. The design was made in Autodesk Fusion 360 and was printed in more than 10 iterations before we have achieved the right fit, function and strength. The parts under mechanical stress are printed using Prusament PC blend and PET-G while the socket is made from PET-G.</p><p>Crash test video:&nbsp;</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=54Lre4hFxh0"></oembed></figure><p><strong>TABARA'S STORY:</strong></p><p>Tabara is a sixteen year old girl suffering from physical challenge due to certain health issues.
