Description
Technical field
The utility model is related to a kind of printing equipment, and in particular to a kind of 3D synthesis printing equipment, belongs to 3D printing technique
Field.
Background technology
SLA (Stereo Lithography Appearance, stereolithography apparatus method) is practical earliest 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, liquid photosensitive resin is irradiated to by the scanning pattern of design
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 on previous cured layer securely, 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 that to use liquid photosensitive resin be raw material.Difference is that DLP is thrown using numeral
Shadow instrument is used as light source, and SLA is laser head.Its technical process is to go out three-dimensional entity model by CAD design first, using from
Dissipate program carries out slicing treatment by model, 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
It is to flow slowly into print area, or even cannot actively flows to print zone, and before photosensitive resin fills up print area, being cannot
Be irradiated curing operation, it is necessary to wait photosensitive resin to be filled up completely with print area after, 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 treatment of the equipment is fast
Degree is still relatively low, it is difficult to realize the quick flowing of photosensitive resin, so the method that photocuring printing at present is generally used is to reduce
Print speed, stopped irradiating and rising print platform before resin is fully cured, and liquid resin is refilled gap, then
Start irradiation solidification, and repeat this process.
In addition, the existing printing device on 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 the DLP printings 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 these reasons, the present inventor furthers investigate to existing 3D printing method, designs one kind and comprehensively beats
Printing equipment is put, and the device can not only realize quick photocuring printing, additionally it is possible to be combined with other Method of printings and printing device,
Fundamentally improve the printing effect of 3D printing so that industrialization is really realized in 3D printing.
