In the fusion of technology and art, SLA (stereolithography) 3D printing technology has become an ideal choice for making complex artworks such as the 12 zodiac animal heads with its high precision and delicate surface quality. Below, we will introduce in detail the whole process from modeling to post-processing and coloring, and finally the final product.


Step 1: 3D modeling

The first step in making the 12 zodiac animal heads is 3D modeling. This step requires the use of professional 3D modeling software, such as Blender, 3ds Max or SolidWorks, to carefully build a 3D model of each animal head based on historical data or design sketches. During the modeling process, special attention should be paid to capturing details, such as the texture, expression, hair and subtle decoration of the animal head, to ensure that the final printed model is lifelike.

After completing the modeling, save the model in STL (stereolithography) format, which is a standard file format widely used in the field of 3D printing, which is convenient for subsequent import into slicing software for processing.


Step 2: Slicing processing

Import the STL file into slicing software such as Magics for slicing processing. The slicing software will decompose the 3D model into a series of 2D slices, each of which corresponds to the material layer that the 3D printer needs to solidify layer by layer during the printing process. In this step, you can adjust the slicing parameters, such as layer thickness, support structure, exposure time, etc., to optimize the printing effect.

In particular, for delicate models such as the heads of the twelve zodiac animals, additional support structures may need to be added to prevent the model from deforming or collapsing during printing. At the same time, reasonable slicing parameter settings can also reduce layer lines and improve surface smoothness.


Step 3: SLA 3D printing

Import the processed slice file into the SLA 3D printer and start the printing process. SLA 3D printing technology uses ultraviolet light of a specific wavelength to irradiate liquid photosensitive resin to solidify it layer by layer. During the printing process, it is necessary to ensure the stability of the printer, as well as the uniform distribution and correct exposure of the resin to ensure the printing quality.

High-end SLA 3D printers such as the Westin SLA600 are very suitable for making delicate artworks such as the heads of the twelve zodiac animals with their high precision and stability. After printing, remove the model and perform preliminary cleaning to remove uncured resin residues.


Step 4: Post-processing

The surface of the printed model may have defects such as layer lines and burrs, which require post-processing to improve the appearance quality. The post-processing process mainly includes steps such as cleaning, polishing, and painting.

Cleaning: Use alcohol or special cleaning agents to clean the surface of the model to remove residual resin and impurities.

Polishing: Use sandpaper or a grinder to polish the surface of the model to remove layer lines and burrs to make the surface smoother. Pay special attention not to over-polish to avoid damaging the details of the model.

Painting: Color the model according to design requirements. First, spray the primer to cover surface defects and enhance adhesion; then spray the topcoat, adjust the color and spray according to the color characteristics of the zodiac animal heads; finally, perform varnish treatment to improve the gloss and protection effect of the model.

During the painting process, it is necessary to pay attention to controlling the thickness and uniformity of the paint to avoid problems such as sagging or color difference. At the same time, it is also very important to choose the right painting equipment and consumables to ensure that the final painting effect meets expectations.


Step 5: Finished product display

After the above series of processes, the exquisite 12 zodiac animal heads models are finally completed. These models not only have extremely high ornamental value, but also contain rich cultural connotations and historical significance. Placing them at home or in the exhibition hall will undoubtedly become a beautiful landscape.

The process of making the 12 zodiac animal heads through SLA 3D printing technology not only demonstrates the perfect combination of technology and art, but also reflects the infinite possibilities of human wisdom and creativity.
