A 3D printing device suitable for large-sized printed objects
ActiveCN224311216UGuaranteed stabilityControl printing thickness accuracyManufacturing recycling3D object support structuresIndustrial engineeringSupport plane
This utility model relates to a 3D printing device suitable for large-size printed parts, belonging to the technical field of 3D printing equipment. It includes a support frame, a printing assembly, a track, and a forming platform. The printing assembly includes a bracket and a sand-laying device and an inkjet printing device mounted on the bracket. The support frame has a built-in lifting drive mechanism, whose drive end is connected to the bracket to drive the bracket to move up and down. The track is located below the printing assembly. The forming platform is movably mounted on the track. This utility model replaces the previous gradually descending forming cylinder technology with a technology that controls the printing assembly to rise gradually through a lifting drive mechanism. During the printing process, the forming platform is only responsible for bearing the continuously increasing weight of the material layer. Therefore, the lifting drive mechanism does not experience the situation of continuously increasing force as the printing process progresses, as in traditional technologies. This allows for more precise control of the printing thickness and accuracy. Furthermore, unlike the high requirements of forming cylinder structure manufacturing, it effectively saves manufacturing costs.
