Description
Technical field
The invention belongs to industry manufacturing technology field, relate to a kind of numerical control former based on fused deposition (FDM) technology, manufacture field for related industries such as Making mold, non-standard component production, complicated structure body processing.
Background technology
FDM technology, i.e. fusion stacking technology, the abbreviation of FusedDepositionModeling, it is properly termed as again fused deposition technology, is the one of rapid shaping technique. The material of this technology is usually thermoplastic, such as wax, ABS, PC, nylon etc., use wire rod feed.
FDM technology is now mainly used on the manufacture equipment such as 3D printer, and the technological principle based on the 3D printer of FDM mainly utilizes filament shape raw material and fusible backing material to be transferred up to extrusion head from the automatic loader being positioned at material cabin. In squeeze bulb, material is heated to semi liquid state, through the extruding of two extruding jet mouths, extrudes semifluid material, deposits into point-device thin layer on forming substrate. Printhead moves in coordinate axes X, Y-direction, and deposition substrate declines along Z axis, and the prototype and the backing material thereof that have shaped deposit from bottom to top layer by layer. Increase along with height, the area of synusia profile and shape all can change, when shape has greatly changed, upper strata profile cannot provide location and supporting role fully to current layer, this is accomplished by designing some supplementary structures-" support ", succeeding layer is provided location and supports, to ensure the smooth realization of forming process.
This technology, without laser, uses, safeguards that simply cost is low. By the ABS prototype manufactured because having higher-strength, it is used widely in product design, test and evaluation etc. Develop again the moulding material of the higher intensity such as PC, PC/ABS, PPSF in recent years so that this technology likely directly manufactures functional features. Owing to this technology has some remarkable advantages, this technical development is extremely rapid, and the share that current FDM system has been installed in rapid forming system in the whole world is approximately 30%.
FDM increases material manufacturing technology advantage and essentially consists in: (1), do not have a consumable accessory, safeguards simple, and operating cost and maintenance cost are low. (2), plastic wire material, it is easy to cleaning, changes, and preserves: compared with other technology using powder and liquid material, silk material cleans more, it is easy to changes, preserve, will not in a device or be formed about powder or liquid contamination.(3), post processing is simple: the time only needing a few minutes to arrive a quarter peels off and supports, and prototype can use. And applying now more SLA, SLS, all there is the step of cleaning residual liquid and powder in the technology such as 3DP, and needs to carry out post curing treatment, it is necessary to extra auxiliary equipment. These extra postprocessing working procedures one are to easily cause powder or liquid contamination, and two are the increase in the time of several hours. (4), shaping speed is very fast: FDM technology can be passed through to reduce the method for prototype compaction rate and improve shaping speed. By testing, having the model of some construction features, the highest shaping speed can reach 60 ccs/hour. By software optimization and technological progress, it is contemplated that the high speed of 200 ccs/hour can be reached. (5), material property is good, it is always up the major advantage of FDM technology: its ABS prototype intensity can reach 1/3rd of injection-moulded plastic part, develop again PC in recent years, PC/ABS, the materials such as PPSF, intensity already close to or exceed common injection-moulded plastic part, can be (on probation in some specific occasion, maintenance, temporary transient replacement etc.) under directly use. In plastic part field, FDM technology is a kind of quick manufacture being particularly suitable for.
Existing FDM technology 3D printer still suffers from following shortcoming in forming process: base plate is relatively extruded spout and is respectively provided with three degree of freedom, can move along tri-directions of X/Y/Z, and every layer is X-Y scheme, prolongs in Z-axis direction successively stacking formation three-dimensional structure. Being there is very big impact by the selection of molding bottom surface in slicing mode and forming process, the structures such as part, hollow housing, hole that lean out of component often need to add to support just to carry out print procedure, and are susceptible to deformation in the course of processing. The component produced presents anisotropy in mechanical property, and the shearing strength at intersection of component cuts, the ability that stretches is very weak, and this also constrains the machine-shaping to complicated applied force component of the existing FDM technology 3D printer.
Man-hour is added using existing FDM former to carry out component, for avoiding or optimizing these problems, generally requiring the appearance avoiding some complicated shape when component designs, single also therefore the constraining of moulding process utilizes the development increasing the method for designing that material manufacture carries out part processing.
