Abstract: The present disclosure belongs to the technical field of advanced manufacturing auxiliary equipment, and discloses an independently temperature-controlled high-temperature selective laser sintering frame structure, comprising a galvanometric laser scanning system, a powder feeding chamber, a forming chamber and a heat-insulating composite plate, and targeted optimization design is performed on the respective functional components. According to the invention, the independently temperature-controlled frame structure can simultaneously ensure the uniformity of the powder preheating temperature field of the powder feeding chamber platform and the uniformity of the processing temperature field of the forming chamber platform, so that powder on the powder feeding chamber platform can reach the sinterable temperature before being conveyed, and conveyance of cold powder to the sintered melt is avoided, thereby reducing the possibility of warpage of the parts while reducing actual sintering delay time and improving actual sintering efficiency. The independently temperature-controlled frame structure of the present disclosure is particularly suitable for high-temperature laser sintering of high-performance polymers such as polyaryletherketones and aromatic polyamides at 400° C.

Abstract: The disclosure belongs to the technical field of additive manufacturing, and discloses a flexible piezoelectric sensor based on 4D printing. The sensor includes a magnetic part and a conductive part, wherein: the conductive part includes two substrates disposed opposite to each other and a spiral structure disposed between the two substrates. Both the two substrates and the spiral structure are made of conductive metal materials. The magnetic part has a flexible porous structure and is arranged between the two substrates to generate a magnetic field. When the two substrates are subjected to external pressure, the spiral structure and the magnetic part are compressed simultaneously, the magnetic flux passing through the spiral structure changes, and the voltage of the two substrates changes, by measuring the voltage change of the two substrates to reflect the change of external pressure, the pressure measuring process is achieved.
