About Project

Why was Xiangyang so difficult to conquer? This 2.7 × 1.4 m museum model answers the question. Installed at the Xiangyang City Wall Cultural Exhibition Hall inside Linhan Gate Tower, it reconstructs the city’s Ming- and Qing-era layout and defensive landscape.

The model includes the Han River, Xiang River, Tanxi Lake, the surrounding Xianshan mountain ranges, the fortified wall, and six city gates. Within the walls are more than one hundred representative structures, including government offices, princely compounds, academies, temples, examination halls, bridges, workshops, shops, and homes. Seen from above, these elements reveal both the city’s civic organization and the natural barriers protecting it.

The rigid city elements were produced in a sand-based composite using Binder Jetting 3D printing. The process was well suited to the project because some miniature architectural features were only a few millimeters high and would have been difficult to reproduce consistently by hand. It also required no dedicated mold or support structures. The printed walls, towers, compounds, and urban buildings were integrated into a scenic base with painted terrain, glossy water effects, vegetation, color accents, and location labels. Historical research, expert consultation, digital modeling, printing, and scenic assembly took the creators more than three months.

For international museums, visitor centers, heritage sites, and urban exhibitions, the value is larger than visual accuracy: the model turns military geography and historical planning into an experience visitors can understand in seconds.

Solution

  • Step 1: Gather historical maps, written records, surviving architectural references, and expert input to define the reconstruction period and city layout.
  • Step 2: Build a layered digital model covering the mountains, waterways, defensive walls, six gates, street network, compounds, landmark buildings, and residential blocks.
  • Step 3: Scale and simplify fragile details selectively so roofs, walls, towers, bridges, courtyards, and buildings remain readable and manufacturable at miniature size.
  • Step 4: Divide the digital city into manageable sections and produce the required walls, gates, towers, compounds, and building components in a sand-based composite using Binder Jetting.
  • Step 5: Cure the printed sections as required, excavate them from the powder bed, remove loose sand from fine rooflines and wall details, and apply the specified strengthening or sealing treatment.
  • Step 6: Assemble the printed elements on the 2.7 × 1.4 m base, then integrate terrain, waterways, vegetation, roads, paint, and other scenic treatments.
  • Step 7: Add location labels, verify the historic and geographic relationships, protect the completed display, and install it at the exhibition hall.
