Abstract

The invention relates to a nozzle device of a 3D (Three-dimensional) printer, aiming at solving the problem of the existing 3D printer under the FDM (Frequency Division Multiplexing) technology that color printing cannot be carried out. The nozzle device is characterized by comprising a housing; a three-color chamber, a mixing chamber and a nozzle are arranged in the housing from top to bottom in sequence; the three-color chamber is composed of three independent chambers which are separated from each other; and a plastic wire with one of three primary colors passes through each of the chambers; and a transmission device, a heating device and an electric valve are arranged in each of the chambers. According to the nozzle device of the 3D printer, the plastic wires can be fused before being sprayed out from the nozzle, so that the true 3D color printing is realized; in addition, the 3D color printing only needs one nozzle; and the nozzle device is low in price and convenient to popularize.

Description

technical field [0001] The invention relates to the field of a 3D printer nozzle, in particular to a 3D printer nozzle device. Background technique [0002] 3D printing technology, also known as Rapid Prototyping Manufacturing (RP technology for short), can be divided into stereolithography (Stcmolithography, SLA), laminated object manufacturing (Laminated Object Manufacturing, LOM), melting Deposition manufacturing (Fused Deposition Modeling, FDM), selective laser sintering (Selective Laser Sintering, SLS), etc. The biggest difference between FDM rapid prototyping system and SLA, LOM, SLS and other systems is that FDM does not use a laser system, so the cost can be minimized, and it is also the most widely used 3D printing technology at present. [0003] The FDM process generally uses filamentous materials with low melting points, such as PLA or ABS plastic filaments, which do not use high-energy-density lasers as heat sources, and only need to heat the filaments to a molt...
