(patent CN203665945U, patent CN201410795471.6 and patent is seen by disturbance in various degree
CN201410027198.2), this disturbance makes to need additionally to increase during the overhanging portion of stereomodel supporting construction, otherwise exists
Under perturbation action, overhanging portion can occur dislocation and deformation in forming process.
Paving liquid device in the patent application of Application No. CN201510799531.6 passes through atomising device by photocuring liquid
On workbench, it is laid to photocuring liquid from level to level after being atomized into fine drop, then uses liquid level detection measurement device
The height and position of photocuring liquid level, then decline shaped platform, though the method reduces disturbance to a certain extent, but due to this
Viscosity of material is required low by method, is generally less than 50cps, and the most just the requirement to material is higher, limits material model
Enclose.Additionally, this art solutions is provided with the atomising device of complexity, it is difficult to safeguard cleaning, and atomising device is by photocuring
Liquid mist turns to droplet to be needed under high pressure to work, it is desirable to higher, and when particularly atomising device carries out spreading liquid, it spreads liquid layer thickness
It is difficult to ensure that uniformly, and tiny bubble can be produced, thus affect paving liquid effect, and then affect photocuring parts quality, and by
In paving liquid it is difficult to ensure that liquid laying speed uniformly can be made slow.
