[0018] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0019] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0020] Embodiment 1 The present invention selects the training method of the generative model, the existing computer three-dimensional modeling software, and the available 3D printing equipment according to the needs, and adopts the existing technology and materials for implementation. In this embodiment, Stable Diffusion1.5 is used as the base (generative) model to train the gray plastic relief Lora generation model, the Zbrush modeling software is used to convert the two-dimensional image into a 3D model, the Rhinoceros modeling software is used to complete the mold design, the finite element analysis software is used to analyze the overall stress of the gray plastic relief, and the desktop 3D printer is used to make the gray plastic relief template component, and the construction is carried out on the wall.

[0021] like Figure 1 As shown, a method for constructing a Lingnan gray sculpture relief by mold forming based on AI generative design includes the following steps: S1. Preparation and testing of paper tendon ash and straw tendon ash.

[0022] S11. Preparation of straw ash: Put 5cm long dry straw soaked in water into a large container such as a large vat or barrel, and spread it to 5cm thick. Use lime and medium sand with a sand-ash ratio of 2:1 to make lime paste, then spread a layer of lime paste and cover the lower straw completely. Then slowly pour clean water along the inner wall of the large container (the amount of water should exceed the straw and lime paste layer by 30cm). Open it after sealing, soaking and fermenting for at least 15 days. After a long period of soaking and fermentation, filter out the upper layer of light yellow and clear lime water after opening to keep it for color adjustment in the future. Then stir it according to the ratio of kilograms of straw ash to kilograms of brown sugar.

[0023] Preparation of paper tendon ash: Soak 100kg of quicklime in 300kg of clean water, and then filter it with a fine sieve to make it lime oil. Then add 2.5kg of brown sugar and 3kg of glutinous rice flour in proportion and stir to make it smooth and delicate. Then soak and mash 15kg of Yuanbao paper to make paper tendons. Finally, mix the lime oil and paper tendons and seal them for about 20 days. Take them out and mix them before use. After the paper tendon ash is mixed with the pigment, it becomes color ash.

[0024] The above method is only a reference for preparing grass tendon ash and paper tendon ash. The specific production method can be adjusted according to the region and materials.

[0025] S12. Use a cubic compression test block mold with a side length of 70.7mm to cast the (compression) test blocks of paper-reinforced ash material and straw-reinforced ash material. Use a ash shovel to tamp evenly during pouring. The number of test blocks of each material should be no less than 3. After pouring, vibrate mechanically for more than 2 minutes.

[0026] Use a square flexural test block mold with a cross-sectional side length of 40mm and a length of 160mm to cast the (flexural) test blocks of paper-reinforced ash material and straw-reinforced ash material. Use a ash shovel to tamp evenly during pouring. The number of test blocks of each material should be no less than 3. After pouring, vibrate mechanically for more than 2 minutes.

[0027] S13. Curing under natural conditions at a temperature not exceeding 35°C, compacting with a trowel every 12 hours until it is completely hardened, then demoulding and storing for 90 days.

[0028] S14. Use a universal testing machine for test loading. The loading system can be selected as 25N / s or 1.5mm / s. Due to the shrinkage of the test block, the compressive area, cross-sectional height and other dimensions of the test block should be remeasured before the test loading. If the surface of the test block is uneven, it can be polished flat by hand, or plaster can be filled between the loading head and the test block to ensure that the test block and the loading head are in full contact. During the test loading process, the elastic modulus and Poisson's ratio can be measured by sticking strain gauges or digital image recognition. After the test, calculate the compressive strength, flexural strength, elastic modulus and Poisson's ratio.

[0029] S2. Model training.

[0030] S21. Material collection: obtain pictures of flat gray plastic reliefs.

[0031] S22. Image preprocessing: unify the resolution, use deepboru in the Stable Diffusion webUI platform to match the prompt words, save the prompt words as a txt file with the same name, check whether the prompt word content matches the image content, and add a unique field "huisu" to the prompt word.

[0032] S23, model training: After the prompt words are set, the Lora model is used for training. Among the model parameters, the batch size is determined to be 2, the learning rate is determined to be 0.0001, the optimization algorithm is Adam, the maximum epoch is 8, and the model file is saved every two epochs for model training.

[0033] S24, model selection: Use the model obtained in S23 to generate several gray plastic relief patterns, select the model whose image style matching and clarity of the gray plastic relief pattern meet the design requirements, and select the model with better generation effect of 7396 training steps and 14972 training steps.

[0034] S3. Design and adjustment of gray sculpture relief.

[0035] S31, image acquisition: using the model obtained in S2, taking Stable Diffusion 1.5 as the base model, using landscape and plaster painting as prompt words, to generate a plaster relief pattern.

[0036] S32, design selection: select the appropriate S31 obtained gray plastic relief pattern (2D plastic pattern) according to the design requirements.

[0037] S33. Model conversion: Use Zbrush modeling software to convert the alpha mask generated by the 2D plastic pattern obtained in S32 into height information, model it into a 3D gray plastic relief model, design the shape and relative position of its skeleton according to the graphic features and actual size, and save it as a drawing.

[0038] S34. Mechanical analysis: Import the 3D gray plastic relief model and the skeleton into the finite element analysis software, assign the material parameters obtained in S1 to the 3D gray plastic relief model, use copper wire and steel nails for the skeleton, and assign their material parameters respectively, calculate the self-weight according to the measured apparent density, and calculate the stress and displacement distribution of the structure under self-weight and wind load.

[0039] S35: Determine whether the normal load is met. If the normal load is met, proceed to S4; if the normal load is not met, proceed to S36.

[0040] S36. Model modification: If the local stress of the material exceeds its compressive strength, adjust the local height of the 3D gray plastic relief model, or use a more densely distributed skeleton to meet the normal use load.

[0041] S4. Mould manufacturing.

[0042] S41. Mould design: Rhinoceros modeling software is used to model according to the actual construction size to obtain the mould of the 3D grey plastic relief model. The mould is split as a whole according to the construction size of the 3D printer, and bolt holes for installation and fixation are set around the mould. After splitting, the parts are connected with tension bolts.

[0043] S42, determine printing parameters: import the model file into the slicing software, determine the parameters such as printing consumables, layer height, printing speed, printing temperature, etc., and generate the printing file required for printing.

[0044] S43, mold 3D printing: use the print file obtained in S42 to perform 3D printing on a 3D printer to manufacture various parts of the mold.

[0045] S44, mold post-processing: remove the support, polish the mold surface evenly, and try to assemble it to ensure that there is no damage or missing, so as to obtain a 3D printed mold for construction.

[0049] S53, pouring of grass reinforcement ash: the 3D printed mold obtained in S4 is assembled with bolts, and grass reinforcement ash is poured in the mold. It is vibrated evenly with a vibrating rod or a vibration platform, and compacted with an ash shovel so that the surface of the grass reinforcement ash is slightly higher than the mold plane after pouring, and forms a certain degree of adhesion with the mold surface.

[0050] S54. Mould installation: Install the mould with cast grass reinforcement ash as a whole on the wall surface, fix it with expansion bolts, and scrape off the excess ash paste.

[0051] S55, demoulding: After about a week, check whether the grass reinforcement ash has hardened. If the grass reinforcement ash in the mold has been completely hardened, remove the expansion bolts, dismantle the mold, and further compact it with an ash shovel to obtain a preliminarily completed grass reinforcement ash matrix.

[0052] S56. Apply paper reinforced ash surface layer: Apply a layer of paper reinforced ash on the straw reinforced ash base after demoulding to obtain an uncolored ash sculpture with a smoother surface.

[0053] S57, finishing and coloring: on the uncolored surface of the gray sculpture relief, apply colored gray according to the designed gray sculpture relief pattern. Wait for 3 days until the surface of the gray sculpture relief hardens and dries, and use pigments to complete the remaining coloring to obtain the completed gray sculpture relief. Its cross-sectional structure is as follows: Figure 8 shown.

[0054] S58. Maintenance: The completed plaster relief should be maintained in natural conditions away from water. You can cover it with waterproof cloth, straw mats and other measures. After it is completely dry, continue to water it for a week to prevent it from cracking due to external high temperature. Finally, the plaster relief is completed.
