3D printed microbeams made from cells and ECM appear to buckle. a 3D printed cell–ECM microbeams having lengths L = 5 mm and varying diameters, D, develop undulations over a 24 h period (Scale bar: 250 μm). b Digitally stretched images of beams from (a) accentuate the undulations and reveal a relationship between beam radius, R, and wavelength, λ (lines manually drawn)
