The models may look old, but their styles are still popular in some cities. Each of them is 1.4-meter-high and hollowed to be 3D printed in resin. Then we apply the putties all over its surface so it's hard enough to be placed in the parks.
Solution
Step 1: Examine the 3D models carefully, especially whether the details exceed minimum layer heights.
Step 2: Add supporting structures for the models in case they may break or deform. As they are all monochromatic, no splitting work is needed.
Step 3: Arrange the placement and 3D print the models in one piece with SLA Generic Resin.
Step 4: Cut off the supports and wash the prints with IPA. Spray the prints with a prime after air drying. Polish to remove the marks.
Step 5: Apply the putties all over its surface and paint by hand.
