Abstract
The utility model discloses a kind of elevating mechanism of the 3D printer based on DLP, the leading screw (2) driven by motor (1) that described elevating mechanism comprises motor (1), vertical direction is arranged, the nut slider (3), slide rail (4) and the print platform that match with leading screw (2); The side of described nut slider (3) is provided with the projection vertically extended or groove that match with slide rail (4); Described motor (1) is located at slide rail (4) top; Described print platform level is fixed on the upper surface of slide block (3); The utility model has leading screw uniform force, and lifting error is little, the advantage that print platform not easily tilts.
Description
Technical field
The utility model relates to a kind of elevating mechanism of the 3D printer based on DLP.
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, until obtain three-dimensional entity model at the resin surface be originally cured.
Hardware components based on the 3D printer of DLP mainly includes printer pedestal, projecting apparatus, elevating mechanism and resin storage tank, the elevating mechanism of the existing 3D printer based on DLP generally forms as shown in Figure 2 by the guide post of print platform, motor, leading screw and two print platforms, there is a shortcoming in such structure, weight due to the extension of print platform can cause the unbalance stress on guide post and leading screw, thus the impact that the lifting error producing print platform inclination that is comparatively large and print platform brings printing precision.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of above prior art: provide a kind of leading screw uniform force, and lifting error is little, the elevating mechanism of the 3D printer based on DLP that print platform not easily tilts.
Technical solution of the present utility model is as follows: a kind of elevating mechanism of the 3D printer based on DLP, is characterized in that: described elevating mechanism comprises motor, vertical direction is arranged by motor-driven leading screw, the nut slider, slide rail and the print platform that match with leading screw; The side of described nut slider is provided with the projection vertically extended or groove that match with slide rail; Described motor is located at slide rail top; Described print platform level is fixed on the upper surface of slide block.
The side of described nut slider is provided with the groove vertically extended matched with the protruding rail of slide rail.
The beneficial effects of the utility model are: the utility model is based on the leading screw uniform force of the elevating mechanism of the 3D printer of DLP, and lifting error is little, and print platform not easily tilts.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model based on the elevating mechanism of the 3D printer of DLP.
Fig. 2 is the elevating mechanism schematic diagram of the existing 3D printer based on DLP of tradition.
In figure: 1, motor; 2, leading screw; 3, nut slider; 4, slide rail.
Detailed description of the invention
With specific embodiment, the utility model is described in further details below, but the utility model is not only confined to following specific embodiment.
Embodiment
As shown in Figure 1, a kind of elevating mechanism of the 3D printer based on DLP, the leading screw 2 driven by motor 1 that described elevating mechanism comprises motor 1, vertical direction is arranged, the nut slider 3, slide rail 4 and the print platform that match with leading screw 2; The side of described nut slider 3 is provided with the projection vertically extended or groove that match with slide rail 4; Described motor 1 is located at slide rail 4 top; Described print platform level is fixed on the upper surface of slide block 3.
The side of described nut slider 3 is provided with the groove vertically extended matched with the protruding rail of slide rail 4.
Claims (2)
1. based on an elevating mechanism for the 3D printer of DLP, it is characterized in that: the leading screw (2) driven by motor (1) that described elevating mechanism comprises motor (1), vertical direction is arranged, the nut slider (3), slide rail (4) and the print platform that match with leading screw (2); The side of described nut slider (3) is provided with the projection vertically extended or groove that match with slide rail (4); Described motor (1) is located at slide rail (4) top; Described print platform level is fixed on the upper surface of slide block (3).
