Problems solved by technology

[0005] Since the materials used in the existing rapid additive manufacturing technology are generally filamentous, powdery metal or non-metal, light-cured liquid resin, etc., these materials generally require laser or other equipment to be heated during the curing molding process. Therefore, the existing additive manufacturi...

Embodiment 1

[0024] Embodiment 1, as shown in the figure, the solution curing rapid prototyping manufacturing method of this embodiment includes steps:

[0025] (1) Prepare the solution raw material as the printing raw material, and put the solution raw material into the storage container 1 to maintain its stability and uniformity;

[0026] (2) Utilize computer 2 to carry out program cutting and layering to the product to be formed, form each virtual layer that forms product, utilize program cutting and layering product to belong to prior art, can utilize existing cad design software to finish;

[0027] (3) Adopt the pump 3 to spray the solution raw material in the storage container 1 into the coagulation bath 5 through the print nozzle 4, the coagulation bath 5 is provided with a liftable workbench 7 carrying the product 6, and the pump 3 is controlled by the computer 2 The starting and stopping, the flow rate of the pump and the movement trajectory of the printing nozzle make the raw mat...

Embodiment 2

[0035] Embodiment 2: The difference between the solution solidification rapid prototyping manufacturing method of this embodiment and Embodiment 1 is that: in step (3), the solution raw material undergoes a chemical reaction during contact with the coagulation bath to solidify and form, and the solution raw material It is an epoxy resin emulsion, and the coagulation bath is water, water vapor, air or nitrogen; certainly in different embodiments, the raw material of the solution can also be cement mortar, and the coagulation bath is water, water vapor, air or nitrogen. Nitrogen: The solution raw material can also be anaerobic glue, and the coagulation bath includes water, water vapor, air or nitrogen. Other steps of the solution curing rapid prototyping manufacturing method in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0036] Embodiment three: the difference between the solution solidification rapid prototyping manufacturing method of this embodiment and embodiment one is that: in step (3), the solution raw material undergoes a crystallization reaction during contact with the coagulation bath to solidify and form, and the solution raw material Including lignocellulose emulsion, the coagulation bath is water; of course, in different embodiments, the solution raw material can also be chitosan solution, and the coagulation bath is water. Other steps of the solution curing rapid prototyping manufacturing method in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a solution-curing quick-molding manufacturing method which comprises the following steps: preparing a raw solution material; carrying out program cutting and layering on a to-be-formed product by virtue of a computer; controlling the start and stop of a pump, the flow rate of the pump and the motion track of a printing sprayer by virtue of the computer, so that chemical or physical change occurs during the contact of the raw solution material and coagulating bath and the raw solution material is cured and formed; controlling a liftable work platform to descend to the height which is the same as the thickness of a virtual layer after printing of a physical layer is completed; repeating the previous step until all the physical layers corresponding to the virtual layers are printed. According to the method, the raw solution material is uses as a raw material for rapid material increasing manufacturing; the raw material scope of rapid material increasing manufacturing is widened; the production method of rapid material increasing manufacturing techniques is enriched; meanwhile, during the producing and manufacturing process of the solution-curing quick-molding manufacturing method, no heating device such as a high energy laser is needed; the production process is low in energy consumption and easy to control; the device is relatively simple; the method can be easily used in large-scale application.

Description

technical field [0001] The invention relates to a rapid additive manufacturing method, in particular to a solution solidification rapid prototyping manufacturing method. Background technique [0002] Rapid additive manufacturing technology (also known as 3D printing technology) is a technology that has received widespread attention in recent years. It uses 3D CAD data to accumulate layers of materials into solid prototypes by various means. The main methods are fused deposition technology (FDM), selective laser melting (SLM) or selective laser sintering (SLS), gypsum 3DP printing technology, etc. The raw materials for printing are generally filamentous, powdery metal or non-metallic , light-cured liquid resin, etc. [0003] Stereolithography (SL) technology is based on the polymerization reaction of photosensitive resin, and the ultraviolet laser under computer control scans the liquid resin point by point along the outline of each layered section of the component, so that ...
