Research on the Application and Innovative Practice of 3D Scanning Technology in GRC Shaping

When architectural art meets digital technology, 3D scanning is redefining the boundaries of GRC forms with millimeter-level precision. As an industry practitioner with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has witnessed the collision and fusion of traditional craftsmanship and modern technology. Across the entire chain from detailed design and manufacturing to construction and installation, 3D scanning technology is becoming the key to solving complex forming challenges.

3D Scanning Redefines the Design Dimensions of GRC Forms

In the creation of GRC decorative components, designers' creativity is often constrained by the precision limitations of traditional surveying methods. Through the acquisition of millions of point cloud data points, 3D laser scanning technology can transform natural forms, historic buildings, or complex curved surfaces into editable digital models, providing millimeter-level design benchmarks for GRC forms. In the Dongguan Women and Children's Activity Center project, Qinglong achieved zero-error alignment between design intent and actual construction through 3D scanning of the irregular double-curved exterior walls, earning the project the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award. This technological empowerment not only enhances the artistic expressiveness of GRC products, but also turns "letting design grow freely" from a concept into reality.

Digital Production: A Precision Revolution in GRC Manufacturing

Traditional GRC component production relies on manual mold replication, which is prone to cumulative errors; digital production processes driven by 3D scanning have completely changed this situation. The intelligent production line established at Qinglong's production base in Nanning, Guangxi, imports scanned point cloud data directly into the CNC machining system, enabling precise mold engraving and standardized component production. Taking the light-transmitting concrete project at Century Plaza on Nanjing East Road as an example, through 3D scanning analysis of the distribution of light-transmitting aggregates, the Qinglong team successfully optimized the mix ratio parameters between the UHPC matrix and the light-transmitting materials, increasing the light transmittance of the finished products by 15%; the project won the Silver Award of the first UHPC Construction Engineering Innovation Award. This closed-loop system of "scanning-modeling-smart manufacturing" has shortened the production cycle of GRC products by 30%, while keeping dimensional deviations within ±2mm.

Technical Synergy in Full Lifecycle Management

As a national high-tech enterprise integrating detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong applies 3D scanning technology throughout the full lifecycle of GRC projects. During the construction phase, comparing point cloud models generated from on-site scanning with design models allows structural deviations to be identified in advance and pre-adjustments to be made, ensuring the precise installation of complex GRC curtain walls; during after-sales maintenance, regular scanning monitors component deformation data, providing a scientific basis for preventive maintenance. This full-chain technical synergy is precisely the core competitive strength of Qinglong as a participant in the formulation of GRC industry standards (having taken part in compiling the Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC), JGJ/T423-2018).

From classical European moldings to modern irregular curtain walls, the evolution of GRC materials has always kept pace with technological innovation. With 28 years of industry experience as its foundation, Qinglong Group has deeply integrated digital technologies such as 3D scanning into its UHPC/GRC/GRG/GRP product system, not only providing designers with a broader creative space, but also creating architectural works for owners that combine artistic value with engineering quality. Driven by the mission of "creating beautiful architecture," this practice of fusing technology with art is propelling the new architectural decoration materials industry toward a more precise, more efficient, and more imaginative future.
