Material and methods
3.1. Specimen preparation
All specimen preparation experiments were carried out usingReaLizer SLM50 apparatus. It can produce objects of layer thickness as small as 20 mm using fiber laser beam (1070 nm)focused to 100 mm. Laser beam is directed to the of anew powder ayer by mirrors which reflect the beam in twoaxes. Additional powder layers are applied and leveled ิby amobilewiper which rotates on its axis to feed the material ontothe building platform lowered by thelayer thickness
(Fig. 1).Experiments were conducted using
