Description
Technical field
The present invention relates to three Dimensional Printing of Rapid Prototyping technical field, particularly relate to a kind of 3 D-printing list and drive auxiliary support
Device.
Background technology
Three-dimensional printing technology (one of Rapid Prototyping technique), is the fast short-term training that the eighties in 20th century, middle and late stage grew up
The in-depth of shape technology and development, based on mathematical model file, carry out constructed object by the way of successively printed material.Rely on
Greatly technical advantage, three-dimensional printing technology and big data, cloud computing, the Internet etc. is emerging and advanced technology becomes digitized system
The main contents made, are also the driving main forces of " made in China 2025 ", are described as being expected to produce " industrial revolution for the third time "
Representative art.
The technical characterstic of 3 D-printing successively superposition so that the forming process with hanging structure part must be introduced into auxiliary
Support, need to remove these supplementary structures after manufacturing molding.The generation method of supporting construction always three-dimensional for a long time is beaten
The bottleneck of print technology development, it has important impact to molding time, manufacture surface quality.About 3 D-printing support generation side
Method has a large amount of scholar to study, and reaches save the time-write interval and save the mesh of backing material by optimizing support generating method
's.In these methods, backing material is exactly often printed material itself, has nonrepeatability, needs extra time after having printed
Removing these auxiliary support structures, not only waste printed material is also lost time.
Meanwhile, three-dimensional printing technology there is also some limitation, (the mould when needing to there is suspending part in the model printed
It is empty under certain part in type, such as bridge), after material extrusion, set the most just cannot shape nowhere, asks to solve this
Topic, printer needs first to print enough support modules, supports module independent of the model that need to print, for the model that need to print
Suspending part provides fixation point.After model has printed, suspending part is solidified as solid, the most just can remove supporting module.
Supporting module and must meet two conditions, one is stabilized structure, can provide foot for the suspending part of model that need to print
Enough and stable support forces；Two are easy to remove, it is impossible to too tight with the model bonding that need to print, so that cannot shell after model solidification
From.But this supporting construction expends the time, waste silk material, and remove inconvenience.
In order to solve the problems referred to above, can be reduced by process route when improving material or improvement printing at present and prop up
Support structure, the such as patent documentation of application publication number CN 105058798A disclose the support of a kind of fused deposition modeling 3 D-printing
Module and the method for generation thereof, described support module is for supporting the suspending part of the model needing 3 D-printing.Described support module bag
Include multiple support units of spaced arrangement, to provide multiple fixation points to a described suspending part.This support module is compared
In conventional support module, it is possible to while keeping the performance supported, more easily remove from the suspending part of model.But it is new
Shaped material is expensive, and improves technique and program can be caused complicated, and the engine that makes to increase income can not meet printing requirement.
In sum, based on the problems referred to above, for regular geometric cross sectional shape simple 3 D-printing structure, propose one and depend on
Outer boundary structure forms auxiliary and supports to reach saving material and to save the time-write interval is the most necessary.
Summary of the invention
The invention provides a kind of 3 D-printing list and drive auxiliary support apparatus, it is achieved three-dimensionally shaped body exempts to print support,
Save printed material and molding time, be particularly suitable for simply supporting the mass production of print structure part.
