Description
Affiliated technical field
The present invention relates to rapid shaping technique, specifically, the present invention relates to a kind of material system that uses for the 3-D spraying binding rapid shaping technique, comprise base-material and with the supporting caking agent of this base-material, particularly based on the base-material and the adhesive material system supporting of gypsum with it.
Background technology
3 D-printing (the Three Dimensional Printing that at first proposes by (US patent 5204055) such as the Sachs of Massachusetts Institute Technology, 3DP) Rapid Prototyping technique is the most vital technology in the at present quick shaping industry, it has the height process flexibility that traditional production is had no precedent, various tool that need not conventional powder machine-shaping is not subjected to the restriction of any geometrical shape.Because spraying position, spraying number of times, spraying rate can arbitrarily be controlled, different materials can be by different shower nozzle sprayings, spraying substance can be solution, suspension, emulsion and melt substance etc., therefore, the 3DP forming technique can be controlled local material composition, microtexture and surface property at an easy rate.Because the 3DP forming technique for constantly to repeat process of agglutinating on a machine, is easy to design studies, the technology stability problem that does not exist mass-producing to amplify with numerous conventional processes unifications in the industrial production conversion process.The advantage that the 3DP forming technique is the most outstanding is to need not mechanical workout or any mould, just can directly from computer graphics data, generate the part of Any shape, thereby greatly shorten the lead time of product, boost productivity and reduce production costs, really embody the advantage of Rapid Prototyping technique.
3 D-printing is similar to ink-jet printer as a kind of forming technique that does not rely on laser.Concrete printing technological process is at first according to product requirement, set up cad model by computer aided design (CAD), characterize the image of object with this cad file,, cad file is converted into stereolithography form (STL) through the digital processing simulation, by computer control 3 D-printing equipment, notion according to " successively print, be layering " is successively made entity, finishes overall print process, carry out aftertreatment subsequently again, thereby prepare object with special external form or complex internal structure.
Traditional detail design all is two-dimentional three-view diagram, though present design software such as UG, Pro/ENGINEER etc. can design three-dimensional view, does not realize real pattern layout, just conceptual design.The 3DP forming technique will make solid model be designed to possibility.Only need convert the part of common software design to the STL form, utilize the 3 D stereo printer again, need not be how long, real three-dimensional stereo model will appear at the planner in face of.So just can reduce expenses greatly, reduce unnecessary waste, but also can accelerate Products Development, dominate the market rapidly.
The 3 D-printing Rapid Prototyping technique mainly contains following three kinds of main modes: spraying microparticles, spray ink Printing moulding, 3-D spraying binding.
Wherein, the process principle of 3-D spraying binding is according to the three-dimensional data model in the computer, and prototype or part are carried out hierarchy slicing, obtains the outline data of each layer cross section.Computer is the printing head on the data message control three-dimensional printer in view of the above, layering cross section profile according to prototype or part, on the material powder layer that each layer completed in advance, spray one deck liquid adhesive selectively, the path material that sprayed caking agent is bonded in together, form a sheet entity profile, and elsewhere remains bulky powder with small thickness.After one deck powder forming is finished, following one deck powder bonding, so circulation successively is piled into one after bonding layer by layer, obtains a three-dimensional space entity, removes powder and carry out the back sintering just to produce designed product innovation exemplar, model or mould.
The material system of 3-D spraying binding Rapid Prototyping technique comprises suitable powder binder and the adhesive solution that matches with it.Wherein require to have at least following performance for powder binder:
1, particle is little, even, does not have obviously and reunites;
2, mobility of particle is good, can be paved into thin layer;
3, when the solution jet impact, base-material can not produce depression, splatter and hole;
4, with the adhesive solution effect after can very fast curing.
Also require to possess following performance at least for adhesive solution:
1, stable performance, the energy standing storage;
2, printer head there is not corrosive nature;
3, have enough low viscosity and sufficiently high surface tension, so that can from printer head, extrude according to the flow of expection;
4, be difficult for drying up, can prolong the anti-duration of congestion of printer head.
In addition, should guarantee that also employed base-material and caking agent are all nontoxic, pollution-free.
