Abstract: A high-speed additive manufacturing apparatus includes a main body, a sintering module, a product carrying member, a raw material carrying member, and a raw material wiper. The main body includes a printing tank and a raw material tank adjacent to the printing tank. The sintering module is arranged on the main body. The sintering module includes a plurality of sintering light source assemblies. Each of the sintered light source assemblies has a light beam emitting end. The light beam emitting end emits a sintering light beam. The light beam emitting ends of the sintering light source assemblies are arranged in a plurality of rows. Each light beam emitting end in one row is unaligned with the light beam emitting end in adjacent rows along a direction in which the light beam emitting end moves.

Abstract: An insole with heat generating system is disclosed, which comprises an insole, a piezoelectric module disposed inside the insole and electrically connected with each other to form an electrical circuit, two flexible conductive strips having a first conductive copper piece and a second conductive copper piece disposed thereon, and at least one resistive heating chip. Wherein the piezoelectric module generates the electrical energy through stepping on the insole, and then turns into the heat energy through the resistive heating chip, thereby generating a temperature for the insole, so the insole with heat generating system can adjust the temperature appropriately, its safety is high, most importantly, the invention does not need to add the battery to generate heat.
