Description
Technical field
The present invention relates to 3D printing technique field, be specifically related to the 3D printing side of a kind of 3D print die and this mould
Method.
Background technology
Along with the development of science and technology, make mould by 3D printing technique (i.e. rapid shaping technique) at present, especially for
Small lot batch manufacture and the complex mould of shape, day by day become trend.Not only can shorten whole by 3D printing and making mould
The construction cycle of product, and become the source driving innovation.The motility that 3D prints allows an engineer to enough trials many times
Iteration, and can reduce because Design of Dies revises the front current cost that brings, can be that engineer brings unlimited selection to improve mould
The design of tool.When target component is made up of several subassemblies, 3D prints to be had Integration Design and reduces the energy of amount of parts
Power, this, simplifies assembling product process and can reduce tolerance.3D prints the shorter production cycle, is suitable for complex geometry shape
Shape, and reduce the ability of final manufacturing cost so that enterprise can manufacture substantial amounts of personalization tools to support custom component
Manufacture.
In 3D printing technique, what master was conventional is fused glass pellet technology.Fused glass pellet technology belongs to single-point energy
Load mode, shows as scanning filling path.Calculating in printing path data step according to model slice, based on discrete/heap
Model file (said three-dimensional body unit), at data processing stage, is first separated into section by the fused glass pellet technology of long-pending principle
(two-dimensional surface unit), is separated into section path (one dimensional line unit) the most further, calculates use according to two dimension slicing information
Machining locus path in final scanning filling.The filling algorithm being now widely used for fused glass pellet technology mainly has:
Contour offset filling algorithm, parallel grid scanning filling algorithm and mixed path filling algorithm etc..
(1) grid scanning pattern: it utilizes Sorted Edge table method to obtain one group of parallel lines and polygonal intersection point of cutting into slices, and obtains
After scan lines, these scan lines head and the tail are coupled together and forms scanning filling path；On the basis of grid scanning pattern,
The grid scanning pattern algorithm parallel grid scanning filling algorithm of feature based subregion, it is possible to approximation, parallel complete whole
The scanning filling process in individual two dimensional surface region to be formed.
(2) Contour offset scanning: the scan line of this scan mode is parallel to boundary profile, has from inside to outside and by extroversion
Interior two types.Subregion biasing scanning algorithm, takes in certain area to bias filling mode, partially near internal and external contour line
Postpone the new profile obtained and take subregion algorithm, each region got the most again is biased scanning filling respectively.
(3) mixed path filling algorithm: take Contour offset path scanning algorithm to enter around the contour loop of slice of data
Row is filled several times, and outline border inwardly biases, and Internal periphery border is outwardly biased, and to lap in addition respective handling.
Being not filled by region in Contour offset path uses parallel grid scanning filling algorithm to be filled.
Contour loop is grouped: the section obtained by Slicing Algorithm by STL model is made up of some contour loops.Define according to it
The character in region is different, and the contour loop of section is divided into outline ring and Internal periphery ring.When the enclosing region of a contour loop is real
During body portion, this contour loop is outline ring, when be hole portion timesharing be Internal periphery ring.If in an outline ring only contains
Contour loop, then the region that they collectively constitute is exactly an entity area having cavity.And if an outline ring is wrapped
The Internal periphery ring held contains again other contour loop, then the region that they collectively constitute is then connected region more than.More than one
Connected region is grouped by rational contour loop, is segmented into multiple simply connected region.Contour loop grouping algorithm will have complexity
Female section of inclusion relation is divided into the son section only comprising a simply connected region that several are independent, thus can be by former
This extremely complex problem is decomposed one by one, defeats in detail, has purposes widely in quick shaping process software.
Existing mould based on 3D printing shaping is all scanning filling path, improves the success rate of complex model making always
It it is the theme of this field exploration.At fine feature or at characteristic flexural, by the model of Mold Making when separating, fine feature
Owing to the restriction of itself and mold material largely can not embody, or it is not readily separated at the knee model of feature, needs
Processing by external force factor, the success rate that these factors result in existing mold making complex model entity is the lowest.
