Description
Technical field
The utility model is related to a kind of printing equipment, and in particular to the Material control system on a kind of 3D synthesis printing equipment
System, belongs to 3D printing technique field.
Background technology
SLA (Stereo Lithography Appearance, stereolithography apparatus method) is earliest practical quick
Forming technique, using liquid photosensitive resin raw material.Its technical process is to go out three-dimensional entity model by CAD design first, is utilized
Model is carried out slicing treatment by discrete program, designs scanning pattern, and the data of generation are by precise control laser scanner and lifting
The motion of platform；The scanner that laser beam is controlled by numerical control device, by the scanning pattern of design liquid photosensitive resin is irradiated to
Surface, after making one layer of resin solidification in the specific region of surface, after one layer of completion of processing, is generated as a section of part；
Then lifting platform declines certain distance, and another layer of liquid resin is covered on layer to be solidified, then carries out second layer scanning, the second solidification
Layer is bonded in securely on previous cured layer, and 3 D workpiece prototype is so formed by stacking from level to level.
DLP (Digital Light Procession) full name is " digital light projection " technology, the printing technology based on DLP
It is similar with SLA Stereolithography methods, all it is to adopt liquid photosensitive resin for raw material.Difference is that DLP is using numeral throwing
Shadow instrument is used as light source, and SLA is laser head.Its technical process is, goes out three-dimensional entity model by CAD design first, using from
Model is carried out slicing treatment by scattered program, and many two field pictures of generation are irradiated to liquid photosensitive resin table by digital projector
Face, makes one layer of resin solidification in the specific region of surface.After one layer of completion of processing, a section of printout is generated as,
Then print platform is moved a certain distance, and another layer of liquid resin is covered on layer to be solidified, then carries out second layer irradiation, and second consolidates
Change layer to be bonded in securely on previous cured layer, 3 D workpiece prototype is so formed by stacking from level to level.
Current SLA and DLP printing devices are primarily present two problems.One：Because liquid photosensitive resin has necessarily
Viscosity, after print platform completes one layer of solidification and lifting, photosensitive resin will not rapidly fill up the vacancy of print area, and
To flow slowly into print area, in addition cannot active flow to print zone, and before photosensitive resin fills up print area, being cannot
Curing operation is irradiated, needs to wait after photosensitive resin is filled up completely with print area, could again start new one layer and consolidate
Change.In the Chinese patent of Patent No. 201510486721.2, a kind of auxiliary equipment is given, but the process of the equipment is fast
Degree is still relatively low, it is difficult to realize the quick flowing of photosensitive resin, so it is to reduce that at present photocuring prints the method for generally adopting
Print speed, stopped irradiating and rising print platform before resin is fully cured, and made liquid resin refill gap, then
Start irradiation solidification, and repeat this process.
In addition, the existing printing device with regard to photocuring is limited to the operation principle of itself, it is impossible to realize quick
Print, often the workpiece of more than ten centimeter lengths is accomplished by printing 3-5 hour, although machining accuracy is higher, but it cannot
Large-scale production, but for numerous parts, but often have the requirement in some precision, in current various 3D printing methods
Also only have the DLP to print and disclosure satisfy that its required precision；Just because of the two reasons, the 3D for limiting photocuring mode beats
Print-out rate and range of application.
For above-mentioned reasons, the present inventor furthers investigate to existing 3D printing method, designs one kind and comprehensively beats
Printing equipment is put and material control system thereon, the material liquid surface height that the material control system can be in real-time control material pond,
Improve 3D printing efficiency, additionally it is possible to easily fast transition printing type so that the printing device and other Method of printings and beat
Printing apparatus are combined, and fundamentally improve the printing effect of 3D printing so that industrialization is really realized in 3D printing.
