Ball Bearing Solution for 3D Printing Galvanometer
NMB Miniature Ball Bearings enable ultra-precise rotational movements for galvanometers within 3D printing applications which eliminates dimensional errors in the final 3D print.
There are two ball bearings used in each galvanometer for 3D printers. Because this environment can be sensitive to magnetism and all martensitic steel holds magnetic properties, any magnetic effect can cause inaccuracies in the final product. As a result of this, NMB proposed a hybrid solution with ceramic balls reducing any imprecise movement due to magnetic “spring back”.
