Preferably, a plurality of through holes for screws to pass through are formed in the plate body in a penetrating manner, and the screws pass through the through holes and are in threaded connection with the bottom plate to fix the bottom plate and the plate body; when the pre-positioning of the plate body and the bottom plate is realized through the magnetic material, the strong locking of the plate body and the bottom plate is realized through the screw, the displacement of the plate body during printing is further avoided, and the precision of the printed model is ensured.

Preferably, the upper end of the through hole is provided with a counter bore for embedding the end part of the screw; after the plate body and the bottom plate are fixed by the screws, the end parts of the screws are embedded into the counter bores and are level with the upper end face of the plate body, and the flatness of the lower single face of the molded model is guaranteed.

Preferably, the plate body is made of stainless steel; the stainless steel can work safely for a long time at the temperature of-270-400 ℃, no harmful substances are precipitated at high temperature or low temperature, and the material performance is quite stable; the stainless steel has the advantages of corrosion resistance, strength enhancement, difficult fracture and environmental protection due to steel deformation, difficult corrosion, and good ductility and toughness.

Preferably, the magnetic holes are arranged in a circular shape; compare other structures such as preventing, circular shape magnetism hole inner wall is better with magnetic material's laminating degree, and the gap is less, prevents on magnetic adsorption and the bottom plate back, and the plate body can rock by a small margin relative magnetic material, has stopped the possibility of rocking.

Preferably, the magnetic material is a permanent magnetic material; the permanent magnetic material still has stronger magnetism after long-time use to guarantee the adsorption strength between bottom plate and the plate body, prevent to rock because of magnetic material loses magnetism.

Preferably, the plate body is provided with anti-sticking lines; the model after being formed is convenient to take down from the plate body, and the model is prevented from being torn when being taken down.

Preferably, the anti-sticking pattern is a fluctuated structure with height difference in the vertical direction, and the total area of the surface of the highest part of the anti-sticking pattern is less than or equal to the total area of the surface of the lowest part of the anti-sticking pattern;

compared with the prior art, the utility model discloses a magnetic material adsorbs the plate body on the bottom plate, plate body easy dismounting, and the leveling is simple, long service life, and the temperature of platform subassembly matches with shower nozzle spun printing material temperature during the printing, has guaranteed the printing quality, and prints and accomplish the easy dismantlement of back model and get off, is convenient for to the processing of plate body.
