Description

3D printer bottom support structure Technical Field The utility model relates to a bottom supporting structure of a 3D printer, and belongs to the technical field of 3D printers. Background The 3D printer is also called as a three-dimensional printer, is a process device for rapid forming, the working steps of the 3D printer are as follows, modeling is firstly carried out through computer modeling software, if a user has a ready model, the model can also be directly used, such as an animal, a character or a miniature building model, and the like, slicing processing is carried out on the model through software, then the model is copied into the 3D printer through an SD card or a U disk, and after printing setting is carried out, the printer can print the model. The working principle of the nonmetal 3D printer is basically the same as that of a traditional printer, and the nonmetal 3D printer consists of a control assembly, a mechanical assembly, a printing spray head, consumable materials, media and other structures. The fused deposition modeling printer is one of 3D printers, and it uses filiform (wire rod) as the consumptive material, extrudes thermoplastic wire rod (such as PLA, ABS etc.) through heating, and the shaping is piled up to the layer by layer, and is with low costs and easy operation, and need support bearing structure, thermoplastic material (such as ABS, nylon etc.) can shrink when cooling down, leads to printing piece edge warpage even break away from the printer bed, and the heating bed is through keeping higher temperature, slows down material cooling rate, reduces shrinkage stress to promote the printing success rate, and the printer bed after the heating can soften material bottom, makes it laminating the bed surface better. The bottom supporting structure of 3D printer is the carrier that supports printing device, bear the finished product after printing simultaneously, and make glass platform be heated easily after heating bearing structure and lead to thermal deformation, make bearing structure's bottom be difficult to keep the level and influence the printing precision, and be difficult to ensure that glass platform's even is heated, and current bottom supporting structure is fixed, the vibration that printing device removes the production probably makes whole bearing structure take place circumstances such as resonance, lead to bottom supporting structure vibration and make the printing finished product precision reduce, light deformation probably takes place when rising the temperature, spring structure allows the platform to freely stretch out and draw back, avoid the stress concentration or the warpage that rigidity is fixed to lead to, reduce the printing precision.
