Recently, the technical team of ARTECH CNC COMPANY (hereinafter referred to as "ARTECH CNC") brought its new large-size 3D printer to the factory of a customer specializing in architectural sand table and film/television prop production, undertaking the task of printing core components for large architectural sand tables. This on-site printing not only verified the equipment's efficiency and precision in large-scale model production but also solved the pain points of the customer's traditional manufacturing processes through customized technical support, earning the customer's deep trust.

As a long-term service provider in the fields of architectural design and film/television production, the customer recently undertook orders for a large commercial complex architectural sand table project and sci-fi film scene props. It urgently needed to produce 1.2-meter-high and 1.5-meter-wide exterior wall modules for architectural sand tables, as well as 2-meter-long foam mountain props for film/television scenes. Previously, the customer used the traditional method of "segmented manual production + splicing," which not only took as long as 3 days per piece but also often resulted in substandard overall model precision due to splicing errors, and even rework in some cases. After learning about the customer's needs, ARTECH CNC developed a solution of "one-stop printing + customized parameter debugging" based on the performance advantages of its new large-size 3D printer.

Before the start of printing, the ARTECH CNC technical team conducted in-depth communication with the customer's designers: On one hand, targeting the "fine texture" requirements of the architectural sand table exterior wall modules (including 0.5mm-wide window grid lines and 3mm-deep relief patterns) and the "natural curved surfaces and hollow structures" of the film/television foam mountain props, the team imported the CAD design drawings provided by the customer into the equipment's independently developed intelligent slicing software. Through the software's "detail enhancement algorithm," the printing path was optimized to ensure the accurate reproduction of textures and curved surfaces. On the other hand, considering the differences between the ABS material used for the sand table modules (requiring stable high-temperature printing) and the EPS foam material used for the mountain props (prone to deformation and sensitive to high temperatures), the team performed customized parameter debugging on the equipment: For the ABS modules, the nozzle temperature was set to 250℃ and the constant-temperature chamber temperature to 60℃ to prevent material warping; for the foam props, the nozzle temperature was set to 180℃ and the feed rate to 80mm/min, with a dedicated low-speed rotating foam printing nozzle to avoid foam melting or edge chipping. Meanwhile, the team also calibrated the level of the equipment's printing platform and treated it with adhesive to ensure that large-scale models would not shift or fall off during printing.

During the official printing phase, the new large-size 3D printer demonstrated strong performance: In the printing of the architectural sand table exterior wall modules, the equipment operated stably at a printing speed of 150mm/s and completed the overall printing in 12 hours. The window grid lines of the finished exterior wall modules were straight and clear, with a relief pattern depth error of only ±0.03mm, fully meeting the customer's "millimeter-level precision" requirements. In the printing of the film/television foam mountain props, the equipment accurately achieved the gradual transition of the mountain's curved surfaces and internal hollow structures through its 3D path planning function. No polishing was required after printing, and the surface smoothness reached Ra0.8μm, far exceeding the customer's expectations. More notably, both large-scale models were printed "in one complete piece," eliminating the splicing step of traditional processes. The work that originally took the customer 3 days to complete was finished in just 24 hours, increasing production efficiency by nearly 3 times.

During the printing process, the ARTECH CNC technical team stayed on-site throughout to monitor the equipment's operating status in real time: When a slight material feeding imbalance was detected while printing the foam mountain prop at a height of 1.5 meters, the team immediately used the equipment's "real-time parameter adjustment" function to fine-tune the feed motor speed, restoring stable printing in just 5 minutes. At the same time, the team also provided simultaneous training to the customer's operators, explaining the parameter setting techniques for the equipment under different materials and model sizes, as well as key steps such as "nozzle cleaning" and "platform calibration" in daily maintenance, ensuring that the customer could use the equipment independently and efficiently in the future.

"This on-site printing has completely solved our production problems!" the customer's production manager said when inspecting the finished products. He noted that the new large-size 3D printer not only significantly shortened the production cycle of large-scale models but also achieved a qualitative improvement in precision. Taking this architectural sand table project as an example, the rework rate caused by splicing errors, which was originally 10%, can now be reduced to 0, saving nearly 20,000 yuan in rework costs alone. "More importantly, the customized service of the ARTECH CNC team is very thoughtful. They followed up throughout the process from parameter debugging to operation training, allowing us to quickly get started with the equipment—something other suppliers cannot do."

It is understood that after the completion of this on-site printing, the customer has signed a long-term cooperation agreement with ARTECH CNC and plans to purchase 2 more units of the same large-size 3D printer to expand production capacity. The person in charge of ARTECH CNC's marketing department stated that the core value of the new large-size 3D printer lies not only in the performance breakthroughs of the equipment itself but also in the integrated solution of "equipment + customized services." In the future, the company will continue to delve deeper into the production scenarios of customers in various industries, providing more precise technical support and services for the large-scale model needs of different fields, and helping customers achieve the upgrading of production models and cost optimization.
