Description
Technical field
The utility model relates to a kind of printers, more particularly to a kind of photosensitive resin three-dimensional printer.
Background technique
It is divided into top to bottom and bottom to top by the three-dimensional printer molding mode of raw material of photosensitive resin.
Projection pattern from bottom to top is that projector is placed in bottom end, forms table top in resin liquid trench bottom, finally
Cured part is sticked to construction platform surface, and after being finally completed, printout is separated from construction platform.From bottom to top
Advantage is as follows：Construction method structure is simple, because it solves two critical issues：The control of resin sedimentation time and layer-by-layer thickness
System.Building direction from bottom to top requires projection tomographic image by being transferred in resin barrel below material.Construction platform initially with
Transmission window flushes, and successively moves up.Construction platform determines thickness with respect to resin barrel bottom, it is meant that the surface of resin is not
It will affect the building of part.Building mode from bottom to top once only needs the resin of smaller size smaller to launch, and improves material use
Rate reduces the fixed investment of production.The shortcomings that from bottom to top, is as follows：Initial investment raw material are less and produce lasting consumption, it is desirable that
Constantly supplement raw material.There is also the pressure that molecular force and vacuum generate between hardened layer and transmissive window in building process,
Cured layer needs larger external force from optical transmission window separation, and subtle feature is easy to be damaged.It is larger cross-sectional dimension can not to be produced
Workpiece and more fine feature part.
Top-down projecting method is that projector is placed in top, and construction platform is parallel with resin liquid rooved face,
Cured part is successively sunk under resin liquid level with construction platform, is waited after being finally completed, construction platform by printout from
It is lifted out in resin liquid bath.The advantages of from top to bottom, is as follows：Top-down projection pattern, by the way that construction platform is reduced to tree
Product is constructed in rouge bucket.This structure simplifies certain designs, and part receives lesser external force in building, can make product details
Large size product production may be implemented in performance very well.The shortcomings that from top to bottom, is as follows：The thickness of top-down construction method is
By construction platform or previous cured layer, the distance of the upper surface apart from liquid resin is determined.This, which means that, is establishing platform
After descending motion, it is necessary to consider the time consumed by resin surface recovery level.Every layer of resin flow time multiplied by the number of plies, and
And it is included in total construction time, so that production efficiency reduces.The poor resin of mobility needs scraper plate to assist levelling, has at this time
External force causes micro-structure to deform；Striking off the time is also included in total building time.Considered using construction method from top to bottom
Second condition be：Printer is in horizontal plane state, to keep the liquid resin surface determined by gravity factor and structure
Jianping platform it is parallel；Therefore more harsh production environment is needed.In the biggish part of production cross-sectional area, can generate larger
Internal stress, and on liquid level be gas, not enough easily warpage modification, precision are difficult to ensure restraining force under the influence of stress.
