Specific embodiment
Embodiment 1
A kind of adaptive hot spot Method of printing of 3D photocuring dynamic focusing is present embodiments provided, as shown in Figure 1 comprising
Following steps:
The three-dimensional modeling data of S1, building object to be printed, and by three-dimensional modeling data discretization, obtain several layer of mould
Type.Layer model is shape made of being surrounded as several discrete points, when printing device prints, the shape of corresponding each layer model,
Successively printing.
S2, hot spot path planning is carried out to each layer model, hot spot path includes the size of hot spot and the mobile side of hot spot
To the size of hot spot changes according to the area size dynamic of layer model.
When carrying out hot spot path planning, referring to fig. 2, firstly, choosing in layer model is some basic point, it is with basic point
Point, it is mobile to peripheral region.Basic point is chosen for center or the mass center of layer model.
Layer model includes platyopia area 1, wedge angle region 2, profile region 3；
In platyopia area 1, hot spot path is to carry out spiral filling with the hot spot of same size；
In wedge angle region 2, hot spot path is to carry out dynamic filling with the hot spot being adapted with the size of wedge angle；
In profile region 3, hot spot path is with small light spot mode along contour line, closure filling.
Under normal conditions, basic point is located at platyopia area 1, the platyopia area 1 in the present embodiment, when referring to hot spot path planning, no
The meeting region adjacent with profile region, relatively for wedge angle region 2；In platyopia area 1, biggish hot spot can be accommodated, and wedge angle
In area 2, when large spot focuses, it is well over the contour line of layer model.Basic point is arranged in platyopia area 1 by starting point of the basic point
One large spot, next hot spot i.e. second hot spot, to be filled in first hot spot side with first hot spot part cover type
On；Helically circulating type is filled on the side of first hot spot for third hot spot and second hot spot, also, third hot spot with
For second hot spot with covering is partially filled with, third hot spot and first hot spot, which have, is partially filled with covering；Successively, helical ring
Around several large spots, platyopia area 1 is filled；It is counted when the contour line of the positional distance layer model of the pre- movement of hot spot is specific less than one
When value, stop the wound filling of helical ring.The specific numerical value can be the 60%-120% of large spot diameter.
At the last one hot spot of spiral surrounding, it is sequentially reduced the diameter of hot spot, is covered in upper one to be partially filled with
The mode of hot spot is filled one by one to wedge angle direction, and the size of hot spot is to be adapted with the size of wedge angle, according to wedge angle
Different fill paths can be used, referring to figs. 2 and 3 in shape.
In Fig. 2, after hot spot goes to the bottommost in wedge angle, along opposite direction, it is sequentially increased the diameter of hot spot, partially to fill out
The mode for being covered in a hot spot is filled, is filled one by one, until the large spot with spiral surrounding is adjacent；Repetition is several back and forth, directly
The remaining area of each wedge angle region 2 and platyopia area 1 into layer model is filled completion.The mark that filling is completed is weight
It is multiple back and forth during, until the upward hot spot of sharp corner square is covered with the hot spot part of side to be moved respectively, then 2 path of wedge angle region
Planning is completed, i.e., there has been hot spot filling in side to be moved, and part covers.In the above process, the setting of spot size
Method is to preset that next hot spot is identical as the spot size, according to the center of circle for being partially filled with principle and determining next hot spot, meter
The center of circle is calculated at a distance from layer model discrete point, in the range of minimum range, drives the size of next hot spot.
In Fig. 3, hot spot continues spiral filling, until having filled wedge angle region in a manner of size dynamic change.
In above scheme, if basic point is not located at platyopia area 1, directly using basic point as starting point, 2 path of wedge angle region rule are carried out
It draws.
Finally, according to the storage order of contour vector, being filled out with small light spot movement and one by one on the contour line of layer model
Fill the entire contour line of covering.
In above-mentioned hot spot path planning, section is filled in the covering between two adjacent spots, is the spacing of two neighboring hot spot
From 45%-65% suitable filling section is selected according to the mobile speed of the energy size and hot spot of hot spot.
The magnitude range of hot spot is 0.1-0.5mm.For specific printing device, the size of hot spot is by dynamic focusing mirror
Range determines, within the scope of this, maximum hot spot is used to print the large spot in platyopia area 1, and lesser hot spot is for printing wedge angle
The hot spot in area 2 and profile region 3.Certainly, the size of large spot can also be set according to the performance requirement of printing objects, be located at dynamic
Within the scope of the adjustable hot spot of state focus lamp.
In practical operation, acquisition dynamic focusing mirror first can focus adjustable spot size range, further according to the model
It encloses and carries out hot spot path planning, so that printing device be enable to match with the hot spot path planned.
S3, layer model is printed according to the hot spot path that step S2 is planned, printing device dynamic adjustment irradiation hot spot
Size and energy are printed along hot spot path, until printing is completed.It is mainly adjusted by the position of dynamic focusing mirror, dynamic is adjusted
The size of whole irradiation hot spot, goes out light level duty ratio, the energy of Dynamic Matching hot spot by adjusting laser TTL.
On the other hand, the present embodiment additionally provides a kind of adaptive hot spot Method of printing phase of above-mentioned 3D photocuring dynamic focusing
The printing device answered comprising laser, dynamic focusing mirror, scanning galvanometer；
Laser issues laser beam and is irradiated to operating fluid level through dynamic focusing mirror, scanning galvanometer, to make liquid tree
Rouge solidification, by controlling the position of dynamic focusing mirror, the size of hot spot when control prints, control laser TTL goes out light level and accounts for
Empty ratio, the energy of Dynamic Matching hot spot, when realizing practical printing, spot size and the energy of irradiation match, and with rule
The hot spot path pulled matches.
Printing device further includes PC control terminal, and PC control terminal is equipped with hot spot path planning module, light path control module, axis fortune
Dynamic control module.Hot spot path planning module is used to carry out hot spot path planning, hot spot path planning process to each layer model
