Oppo used laser scanning to measure the hinge surface at 0.3 micrometer precision, and then used 3D liquid printing to apply polymer droplets, which it then UV-cured layer-by-layer. This reduces the hinge unevenness from about 0.2 mm to 0.05mm.

There's no getting around that - having two folding sides and one middle one means the Galaxy Z TriFold will be a fat gadget when fully closed. However, it's not unmanageably thick, and people who'll buy the TriFold will likely accept the girth for the benefits they'll get when they unfold the device. After all the Galaxy Z TriFold is thinner than the Galaxy Z Fold5 and that was perfectly acceptable two years ago.
