Description
Technical Field
The invention relates to a 3D printing method, in particular to a solid 3D printing method based on a double/double-section crosslinking material.
Background
3D printing, also known as additive manufacturing (Additive Manufacturing, AM), is a technique for constructing objects by layer-by-layer printing using bondable materials such as powdered metal or plastic based on digital model files. The printing machine has the same working principle as that of common printing, and the printer is filled with liquid or powder and other printing materials, and the products to be printed are sliced and layered to print with the aid of a computer, and the materials are stacked layer by layer to manufacture a entity. Compared with the traditional forming cutting processing mode, the 3D printing can manufacture parts with any complex shape, does not need tools, clamps and multiple processing procedures, realizes free manufacture, solves the forming problem of a plurality of parts with complex structures, shortens the manufacturing period, and is widely applied to the fields of medicine, industrial processing, building production, aerospace and the like, and has wide application prospect.
Common 3D printing modes include light curing forming technology (SLA), selective laser melting technology (SLM), rapid Plasma Deposition (RPD), laser metal cladding (LMD), fused deposition technology (FDM), etc. The earliest 3D printing forming technology, namely the current mature 3D printing technology-photocuring forming technology (SLA), divides the shape of a three-dimensional target part into a plurality of planar layers, scans liquid photosensitive resin with a light beam with a certain wavelength, so that the scanned part of each layer of liquid photosensitive resin is solidified and formed, the part which is not irradiated by the light beam is still liquid, and finally all the layers are accumulated to form the required target part.
Conventional 3D printing requires pretreatment of the material to liquid (molten) or powder form, and structure fabrication is achieved by layered solidification, and the printing process is required to be performed in a relatively stable environment. However, in the face of special environments such as microgravity (or no gravity) or vibratory shaking, the above-described liquid or powder materials may flow, float and spread during printing, where conventional 3D printing schemes may not be applicable. Patent CN111070673a describes a method of 3D printing polymers in the condensed state, which can be used to print certain specific types of polymers in the solid state, such as specific thermosensitive gels and vitrimers, but not suitable for general polymers commonly used in industry.
Disclosure of Invention
The invention aims to: the invention aims to provide a solid 3D printing method using a dual/dual-segment cross-linked material, which can be applied to microgravity, gravity-free or vibration environments.
The technical scheme is as follows: the solid 3D printing method utilizing the double/double-section crosslinking material comprises the following steps of:
(1) Pre-curing the liquid dual/dual-stage cross-linked material to change the cross-linked material from a liquid state to a non-flowing state; or the polymer raw material which can change from the fluid state to the non-fluid state along with the temperature change and can be crosslinked by light or light heat is adjusted to the non-fluid state through the temperature;
(2) Cross-linking and solidifying the non-fluid dynamic material obtained in the step (1) according to the shape of a product to be printed;
(3) Removing the uncrosslinked portion to obtain a 3D printed product.
The dual/dual stage crosslinking material may be solid at a specific temperature, such as at room temperature, low temperature, or high temperature, and may be locally crosslinked by light or photo-heat. The temperature is then changed and the part which is not photo-or photo-thermally crosslinked is softened or liquefied and can be separated from the photo-or photo-thermally crosslinked part.
The dual/dual stage cross-linked materials include low molecular weight materials that can be solid or non-flowable at low temperatures and can be photo-or photo-thermally cross-linked. The dual/dual stage crosslinked material also includes a polymer that is photocrosslinkable at room temperature and is flowable at elevated temperatures.
In the step (1), the dual/dual-stage crosslinking material is a resin which can be crosslinked in two different crosslinking modes, or a resin which is crosslinked in one crosslinking mode under different crosslinking conditions. The two different crosslinking modes are any two of photo-crosslinking, photo-thermal crosslinking, thermal crosslinking or moisture crosslinking. The different crosslinking conditions are different light wavelengths, different light intensities and different irradiation times, or different thermal crosslinking temperatures and different thermal crosslinking times.
Wherein in the step (1), the pre-curing mode is at least one of thermal curing, photo-thermal curing, moisture curing or photo-curing.
In the step (2), the cross-linking and curing method is local heat curing or local light curing. The local heat curing or the local light curing adopted in the crosslinking curing is light beam curing or light beam heating curing. The beam curing or beam heating is to re-crosslink portions of the dual/dual stage crosslinked material using single or multiple beam light intersection.
In the step (3), the specific method for removing the uncrosslinked portion of the material is as follows: the non-re-crosslinked portions were removed with a solvent: after the solvent soaking, the non-crosslinked part is peeled off mechanically. The non-re-crosslinked portions are mechanically peeled off at room temperature or at an elevated temperature.
The principle of the invention: the resins used in the prior art for liquid printing are not pre-curable, whereas solid printing uses special thermosensitive gels or vitrimers. Whereas the present invention uses dual/dual stage cross-linked resins to achieve pre-cure. The dual/dual-section crosslinked resin is pre-cured by heating or illumination, namely, is partially crosslinked, so that the liquid state is converted into a state of being not easy to flow; then, according to the shape of the product to be printed, carrying out secondary crosslinking and curing on the pre-crosslinked resin in a local heat curing or local light curing mode; and finally removing uncrosslinked parts of the material by adopting a solvent soaking and mechanical mode to obtain the 3D printing product.
The beneficial effects are that: compared with the prior art, the invention has the following remarkable effects: (1) Aiming at the problem that raw materials such as liquid, melt, powder and the like cannot be printed normally in special environments such as microgravity, gravity-free or vibration shaking and the like in the conventional additive manufacturing technology, the dual/dual-section cross-linked resin is used for printing in a solid state after being pre-solidified, so that a solution is provided for realizing solid 3D printing; (2) The invention can be applied to special environments with vibration and shaking such as space, steamship, train and the like without microgravity or gravity, and further widens the working environment and application field of 3D printing; (3) The printing method can be used for low-cost materials, is economical and friendly, and can realize the recycling of the materials by adjusting the degree of pre-crosslinking.
