Description
Technical field
The utility model relates to a kind of 3D printer.
Background technology
3D printing technique is actually the general designation of a series of rapid prototyping forming technique, its general principle is all layered manufacturing, in X-Y plane, formed the cross sectional shape of workpiece by rapid prototyping machine by scanning form, and do the displacement of slice thickness at Z coordinate discontinuously, finally form three dimensional articles.3D printing technique common in the market mainly contains 3DP three dimensional printing technology, FDM fusion stacking forming technique, SLA stereolithography techniques, LOM Laminated Object Manufacturing, SLS precinct laser sintering technology, DLP digital light process forming technique etc.3D prints different from traditional removal materials processing technology, is therefore also called to add to manufacture.As the comprehensive application technology of one, 3D prints all many-sided cutting edge technology knowledge such as combining digital modeling techniques, Electromechanical Control technology, information technology, material science and chemistry, has very high scientific and technological content.
DLP forming technique is improvement and the development of SLA stereolithography technology: SLA stereolithography techniques take photosensitive resin as raw material, point by point scanning is carried out by each layering cross section information of part on the photosensitive resin surface of liquid state by computer control laser or ultraviolet light, produced photopolymerization reaction by the thin resin layer of scanning area and solidify, forming a thin layer of part.After one deck has solidified, workbench moves or moves down the distance of a thickness, then apply the new liquid resin of one deck again at the resin surface be originally cured and carry out printing solidification, until obtain three-dimensional entity model.
As shown in Figure 2, resin storage tank 1 ' the feed that the existing 3D printer based on DLP generally adopts bottom transparent, resin storage tank 1 ' is built with the photosensitive resin of liquid state, printing substrate 2 ' level is pressed close to the photosensitive resin layer that resin storage tank 1 ' bottom makes to be full of between the bottom surface of printing substrate 2 ' and resin storage tank 1 ' lower surface one deck liquid state, then computer controls to be positioned at the laser of resin storage tank 1 ' bottom or ultraviolet light and through resin storage tank 1 ' clear bottom by the layering cross section information of part this layer of liquid photosensitive resin layer is carried out to point by point scanning or directly project cross sectional shape by projecting apparatus, to be scanned or the thin resin layer of view field produces photopolymerization reaction and solidifying, form a thin layer of part, then the distance of printing substrate 2 ' moving a setting thickness is controlled, owing to there being a large amount of liquid photosensitive resins in resin storage tank 1 ', be now attached to the photosensitive resin layer being filled with again one deck liquid state between the thin resin layer of having solidified on printing substrate 2 ' and resin storage tank 1 ' lower surface, repeat above-mentioned print procedure, until obtain three-dimensional entity model.But there is following shortcoming in above-mentioned 3D printer: because the 3D time-write interval is relatively long, liquid printed material (as liquid photosensitive resin) easily sinks to the bottom, occur printed material excessive concentration bottom resin storage tank and the too low problem of top concentration, thus the strength of materials that result also in the model various piece printed is uneven; And printing substrate needs to be immersed in the liquid printed material of resin storage tank, printing substrate can take unnecessary liquid printed material out of, also greatly wastes liquid printed material while making troubles to cleaning work.Take out printing substrate to above-mentioned 3D printer to carry out the demoulding to get thing operation not too convenient simultaneously, the bottom surface of hand rest printing substrate is needed when reinstalling printing substrate after delivery type, printing substrate bottom surface of easily making dirty affects the adhesive force of printer model and printing substrate, because model needs the bottom surface being attached to printing substrate, model in print procedure is therefore usually caused to come off.
