Innovative Application and Practical Exploration of 3D Printing Technology in UHPC Shaping

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete) is becoming a new favorite in high-end architectural design, thanks to its outstanding mechanical properties and form-making potential. The integration of 3D printing technology further provides a revolutionary solution for UHPC's breakthroughs in shaping. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group has always driven product upgrades through technological innovation, accumulating rich practical experience in the integrated application of 3D printing and UHPC, and creating customized solutions that combine aesthetic value and engineering reliability for designers and owners.

The combination of 3D printing technology and UHPC first breaks through the limitations of traditional mold manufacturing. Traditional UHPC component production relies on custom molds, which entail high costs and long production cycles for complex shapes, while 3D printing, by stacking materials layer by layer, can directly achieve integrated forming of complex structures such as curved surfaces, hollow-outs, and parametric textures. For example, in a special-shaped facade project of a commercial complex, Qinglong used large-size 3D printing equipment to turn the designer's hyperbolic paraboloid concept into UHPC cladding panels with a precision of ±0.5mm, improving production efficiency by 40% and reducing mold costs by 60% compared with traditional processes. This technological advantage enables UHPC to show stronger design expressiveness in decorative components of landmark buildings such as grand theaters and museums.

From the perspective of material performance optimization, 3D printing gives UHPC components more refined internal structural design. By adjusting printing path and layer height parameters, Qinglong's technical team successfully achieved gradient distribution of UHPC materials—high-density printing is applied at key stress-bearing areas to enhance strength (flexural strength can reach over 25MPa), while hollow structures reduce weight in non-stress areas, lowering overall self-weight by 30% compared with traditional cast components while meeting curtain wall wind pressure resistance and seismic requirements. This “material-on-demand” characteristic allows UHPC to combine artistic appeal with engineering safety in scenarios such as landscape sculptures and shading systems.

Full-chain service capability is Qinglong's core competitiveness in 3D-printed UHPC applications. As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong engages in design collaboration from the early project stage, using BIM technology and 3D scanning to complete digital modeling of components and optimizing joint details through virtual assembly before printing; in the production stage, relying on the 600,000-square-meter annual capacity of its production base in Nanning, Guangxi, it achieves large-scale printing and standardized quality control; during installation, it employs 3D laser positioning technology to ensure precise assembly of complex-shaped components. In the Century Plaza renovation project on Nanjing East Road, the translucent UHPC components produced by Qinglong through 3D printing are a prime example of this full-chain service, and the project won the Silver Award of the first UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

The innovative fusion of 3D printing technology and UHPC not only expands the aesthetic boundaries of architectural decoration but also drives the industry's transition toward green construction. Compared with traditional processes, 3D printing can reduce material waste by 80% and requires no mold storage, lowering carbon emissions in the production stage. As a national “Specialized, Refined, Distinctive, and Innovative” enterprise with a provincial-level R&D center, Qinglong is continuously exploring cross-scenario applications of this technology in materials such as GRC (Glass Fiber Reinforced Concrete), GRG (Glass Fiber Reinforced Gypsum), and GRP (Glass Reinforced Thermosetting Plastic)—for example, using 3D-printed GRG to create seamless curved surfaces for concert hall ceilings, or printing special-shaped GRP components for theme park scenarios.

In the future, as 3D printing equipment grows larger and material formulations are continuously optimized, the printing dimensions and performance of UHPC components will achieve further breakthroughs. Qinglong Group will continue to uphold its mission of “Creating Aesthetic Architecture,” building on 28 years of industry experience and through technological innovation and full-chain services, provide more imaginative architectural decoration solutions for designers and owners worldwide, and promote the widespread application of UHPC/GRC/GRG/GRP materials in the high-end building sector.
