Landmark building model manufacturer

Case study of landmark building display model production
1、 Main structure and material selection
Core frame: use high-density Poly Dragon foam to manually carve the building outline, and embed blockboard in key load-bearing parts to enhance stability. The main building is 3D printed with photosensitive resin to ensure accurate presentation of curved surfaces and hollow structures.
Detail components:
Glass curtain wall: 0.5mm transparent acrylic board laser cut, edges polished to simulate mirror effect;
Roof and decorative lines: brass sheets are manually bent and formed, and welding nodes are processed with micro welding guns;
Base platform: Multi layer oak board collage, with urban road texture carved on the surface.

2、 Partial component forming process
Main building production:
The complex surface structure adopts the “layered stacking method”: first print the basic module, then splice it layer by layer with AB glue, fill the joints with atomic ash, and manually polish them;
Hollow decorations (such as grid curtain walls and carved components) are stacked with etched copper sheets and fixed to a resin substrate with ultraviolet glue.
Scene accessories:
Miniature street lamp: 0.3mm copper wire bent lamp post, with LED light-emitting elements embedded at the top;
Green landscape: Nylon flocking simulates a lawn, and fine wire ties moss to make trees.
3、 Surface treatment and painting
Basic polishing:
Use 400 grit sandpaper for initial grinding of the entire vehicle, with a focus on processing 3D printed layer patterns; Use sponge sandpaper to manually grind the curved surface to avoid edge wear.
Transparent parts are polished with toothpaste to enhance their transparency.
Multi layer coloring:
Main building: Primer sprayed with white acrylic paint, color separation areas covered with masking paper, metal components painted with silver enamel paint;
Glass curtain wall: The back of the transparent acrylic panel is sprayed with light gray gradient paint to simulate real glass reflection;
Aging effect: Use brown stain solution to flow along the building joints, and after drying, gently wipe with a cotton swab to highlight the structural shadows.

4、 Scene based assembly and detail enhancement
Lighting system:
Reserve small holes inside the building to simulate the lighting inside the fiber optic simulation window; The base is hidden with a lithium battery pack, and the lighting mode is controlled by a micro switch.
Dynamic effects:
Rotating observation deck: Connect the base to the top of the building with bearings, and manually rotate it to drive the LED light strip to flash;
Magnetic accessories: detachable small parts such as billboards and flags, fixed with strong magnetic plates for easy scene replacement.

5、 Final effect processing
Overall protection: The entire vehicle is sprayed with matte varnish to prevent oxidation of the paint surface; Transparent components covered with anti-static coating to reduce fingerprint adhesion.
Display base: Black acrylic board laser engraved with building names, with LED light strips embedded at the edges to outline the contours, echoing the model lighting.
By combining traditional manual labor with digital technology, the model fully reproduces the structural features and light and shadow textures of landmark buildings, achieving the expected level of detail accuracy and overall proportion. The base lighting and detachable accessory design further enhance the interactivity and scene immersion of the display
