Component.
Background technology
3D printer is to apply increasingly extensive three-dimensional increasing material manufacturing equipment at present, and stereolithography apparatus is 3D shaping skills
One kind of art, it is mainly exposed to the photosensitive resin of liquid by the cross sectional shape layering of three-dimensional model using the light of specific wavelength
On, and solidify photosensitive resin, so as to form the product with three-dimensional shape.In traditional photocuring 3D printing equipment, its into
Type component include workbench, set below workbench be used for house the cylinder body of liquid photosensitive resin and located at workbench
The material scraper of side.Cylinder interior space constitutes the working chamber of curing molding with workbench.And using reciprocating for material scraper,
Realize that it carries out striking off operation to the resin on mobile work plate.However, the molding assembly of the structure exist it is several great
Technological deficiency：
First, in order that liquid resin can be totally submerged product in itself during each optical scanning, in cylinder body generally
Sinker can be set, and the liquid level for making resin in cylinder body using the continuous decline of sinker rises therewith.However, when the decrease speed of sinker
When too fast, resin can overflow from the edge of cylinder body, so as to pollute the part around cylinder body, printer is completed in product molding
Need to carry out numerous and diverse cleaning afterwards.And with the continuous spilling of resin, available liquid resin amount also constantly subtracts in cylinder body
Few, the phenomenon is in addition to it can cause substantial amounts of liquid resin and waste, the pole when product needs the secondary fine for carrying out surface to be fine into type
Easily there is the not enough situation of amount of resin, had a strong impact on the Forming Quality of product.

Formula contact heating.Because thermal source is directly contacted with outer surface of cylinder block, the speed of conduction of heat, so at hot spot
Liquid resin temperature is higher, easily produces the problem of oxidation, aging.And liquid resinous thermal conductivity is generally relatively low, so cylinder body
The resin temperature of interior different piece is also not quite similar, and the resin temperature highest relative with outer surface of cylinder block contact position, the phenomenon
Liquid resin in cylinder body can be caused to produce Temperature Distribution extremely uneven situation, the normal of resin has been had a strong impact on and used.
6th, with the continuous shaping of product, the liquid resin in cylinder body is also gradually decreased, in order that liquid resin can be complete
Sinker would generally be set in full submergence product, traditional resin cylinder body, make the liquid level of resin cylinder body continuous using moving down for sinker
Rise, so as to realize the feed supplement in cylinder body above product.However, because sinker itself has constant weight and volume, under it
It is difficult to realize apart from upper accurate movement when heavy, so it is difficult the climb of accurate control liquid resin liquid level, cause to mend
The stability and reliability extreme difference of material.And the resin types of different product moldings are different, the calculating that sinker moves down distance needs handle
The factors such as viscosity, the surface tension of resin are taken into full account, so as to be needed in different product moldings under adjustment sinker
