Description
Technical field
The present invention relates to a kind of coating, be specifically related to the preparation method of a kind of coating of the 3D of being coated in printer worktable and this coating, be coated with the 3D printer of this coating and on 3D printer, apply the method for the film that this coating is made.
Background technology
3D printing technique is the one of rapid shaping technique, and its common print procedure is: first by microcomputer modelling software modeling, then the three-dimensional model " subregion " built up is become cross section successively, namely cuts into slices, thus instructs printer successively to print.
Rapid shaping technique in the market is mainly divided into fusion stacking forming technique (FDM), three dimensional printing technology (3DP), stereolithography techniques (SLA), precinct laser sintering (SLS), laser formation technology (DLP) and UV ultraviolet forming technique etc.Melted extrusion modeling forming technique (FDM) is a kind of technical matters conventional in 3D printing technique, principle utilizes thermoplastic, polymeric materials in the molten state, squeeze out from shower nozzle, solidify and form the thin layer of outline shape, then superpose layer by layer and finally form product.The polymer materials that melted extrusion modeling forming technique is comparatively commonly used in the market is acrylonitrile-butadiene-styrene terpolymer (ABS), poly(lactic acid) (PLA), nylon (PA) and polycarbonate (PC).
In 3D printer working process, after the melting material being about 220 DEG C is expressed to worktable as ABS or PLA from shower nozzle, melting material starts to be converted into solid-state, now the contact surface of worktable and melting material can produce an instantaneous sticking power, sticking power sufficiently can ensure greatly carrying out smoothly of print procedure, if sticking power is less than normal, can not complete moulding process.And after printing objects is formed, in the process that printing objects temperature declines gradually, sticking power can corresponding decline, when printing objects temperature is to room temperature, sticking power is sufficiently little, can ensure that printing objects is easy to take off from worktable like this.
In 3D print procedure, if directly printed on the table by melting material, the molecule with worktable interpenetrates by the molecule of the object printed, and causes the object of printing and worktable to be bonded together consumingly, is difficult to take off the object printed.In prior art, the worktable of 3D printer can post a layered paper usually, but; printed material such as poly(lactic acid) directly can infiltrate the inside of paster, with paster adhesion, after printing objects is cooled to room temperature after high-temperature fusion; because printing objects and paster are sticked together, therefore not easily take off.Need in real work with scuppit, object to be separated with paster, such operation certainly will easily destroy object and paster, and with regard to needing, the paster of worktable is changed after often completing one or pieces printing article, and the technique changing paster in real work is loaded down with trivial details, cost significantly improves.

When preparation is coated in the rete of 3D printer worktable 3, obtain coating after performing step S1 to S6 as shown in Figure 1, then perform step S7, the paint spay-coating obtained by step S6 is on the worktable 3 of 3D printer.In prior art, worktable 3 is generally glass or the aluminium sheet of heat conduction, and spraying process can use and is existingly exclusively used in the instrument of spraying or manually completes.
As shown in figures 1 and 3, after performing step S7, then perform step S8, toast the coating be sprayed on worktable 3, final formation can be applied to the rete 31 of 3D printer.Rete 31 thickness on worktable 3 is arbitrary value, and preferred technical scheme is, preferred 50um to the 80um of thicknesses of layers.Worktable 3 directly can be put into loft drier by bake process, and take the type of heating such as electrically heated, infrared, microwave, storing temperature is set as 150 DEG C to 180 DEG C, and baking time continues 60 to 90 minutes.
As shown in Figure 3, the cross section of worktable 3 comprises zone of heating 33, aluminum layer 32 and rete 31 successively.In 3D print procedure, worktable 3 can heat up and remain on a steady temperature under the effect of zone of heating 33, and for different printed materials, above-mentioned steady temperature can be different according to the character of material.Such as, adopt ABS material print time, this temperature is set as 110 DEG C usually, and if application PLA material, then temperature should be risen to 70 DEG C.Be to prevent printing objects from occurring warpage or distortion to the effect that worktable 3 heats.After the temperature melting material that is 220 DEG C contacts with rete 31, melting material temperature starts to decline and is converted into solid-state and can produces a very strong instantaneous sticking power, thus completes the print procedure of object smoothly.Owing to adding aerosil in dope preparing process of the present invention, between the rete molecule being coated in worktable 3, arrangement is loose, intermolecularly can form larger void structure, after print procedure terminates, object is cooled to room temperature, object contact with rete 31 molecule can enter into void structure, and there is not to merge or produce Intermolecular Forces with rete molecule, therefore the sticking power between printing objects and rete 31 can diminish, and directly just can take off object with hand.
Introduce the method preparing rete on 3D printer below.
