A method and apparatus are for surface finishing of pieces obtained by 3D printing. The piece to be treated and a liquid process plasticizer are heated together in a hermetically sealed treatment chamber up to a working temperature lower than the boiling temperature of the process plasticizer. The air/vapor mixture is maintained in continuous circulation in the chamber to keep the temperature and concentration uniform and to contact the piece with the air/vapor mixture to avoid condensate formation on the piece surface and allow process plasticizer vapors to be absorbed by the piece surface without condensate formation. Vapor exposure time is fixed depending on the desired penetration depth. A chamber has heaters, a ventilator for circulating the air/vapor mixture in the chamber to maintain uniform temperature and concentration conditions. A unit separates the process plasticizer vapors from the air/vapor mixture by condensation. A unit filters the residual air/vapor mixture.

Composite materials with adjustable spectral properties comprised of IR-reflecting micro-domains overlaying an IR-transparent elastomeric matrix, and capable of dynamically controlling IR radiation transmission are described, as well as methods of fabrication thereof. Systems with capabilities to regulate IR radiation (including heat) transmission based thereon, and methods of regulating IR radiation transmission (including thermal regulation) using the same are also provided.

A robotic limb is described. The robotic limb has a closed tubular casing made of viscoelastic material defining a chamber containing an incompressible fluid. The closed tubular casing has a sheath formed by substantially inextensible intertwined wires. In the chamber there are groups of transverse actuators axially spaced from each other, connected to the sheath and adapted to reversibly contract the closed tubular casing at least partly in the radial direction. The robotic limb also has longitudinal actuators adapted to reversibly contract the closed tubular casing at least partly in the axial direction being connected to each of the groups of transverse actuators.
