From commercial pellets of recycled polyethylene terephthalate glycol (R-PETG), 1.75 mm diameter filaments for 3D printing were produced. By varying the filament’s deposition direction between 10° and 40° to the transversal axis, parallelepiped s

The pseudoelastic responses of two types of iron base shape memory alloys (SMAs) were introduced and discussed. The former was based on Fe-Mn-Si system, obtained by classical (CM) and by powder metallurgy (PM) manufacturing. The latter was based on F
