3D Printing in Smart Inspection Vehicles
Creatbot technology Limited & Henan College of Transportation industry-university cooperation project
This article elaborates on the in-depth industry-university cooperation project between CreatBot and Henan College of Transportation (hereinafter referred to as "Henan Jiaoyuan"). Seizing the opportunity presented by serving SMP Robotics, a globally leading robotics technology company, and its intelligent inspection robot, both parties fully leveraged their respective advantages in technological R&D and talent cultivation. They successfully utilized CreatBot's large-format industrial-grade 3D printing technology to complete the complex, lightweight, and highly customized shell design and rapid manufacturing for this robot. This case not only validates the application value of industrial-grade 3D printing in the high-end equipment manufacturing sector but also explores a successful path of "industry-education integration and collaborative innovation," providing a replicable model for the smart manufacturing industry.
Background and Challenges
With the deepening advancement of the "Made in China 2025 " strategy, the application of intelligent robots in fields such as industrial inspection, security, and logistics has experienced explosive growth. Intelligent inspection robots, with their ability to operate autonomously, accurately perceive and work 24/7, have become core equipment for ensuring the safety of modern facilities and enhancing operational maintenance efficiency. Their application scenarios widely cover：
- Industrial Sector: In complex environments like factories, power stations, and
petrochemical plants, they replace manual tasks for equipment status monitoring,
thermal defect identification, gas leak detection, and gauge reading, effectively
avoiding operational risks in hazardous environments. - Infrastructure: In large public facilities like data centers, airports, and subway stations, they perform all-weather security patrols, personnel intrusion detection, and fire warning, building a comprehensive security system.
- Energy Industry: In outdoor energy bases like photovoltaic power stations, wind farms, and substations, they automatically complete tasks such as photovoltaic panel inspection, equipment inspection, and line patrols, significantly reducing operational maintenance costs.
SMP Robotics, as an internationally renowned developer of ground robots, has deep expertise in this field. Its products need to operate stably in various harsh and diverse environments, thus placing extremely high demands on core components like the shell regarding lightweight design, environmental tolerance, and rapid customization capabilities.
During the R&D process for the intelligent inspection project at Henan College of Transportation, the shells of its teaching robot equipment primarily faced the following issues:
- Structural Design and Aesthetic Flaws: The original shell had a rough shape,
lacking standardized industrial design. It did not convey the sense of technology and professionalism expected of specialized inspection equipment, affecting the
intuitiveness of teaching demonstrations and professional appearance, and hindering effective student understanding of modern intelligent inspection equipment structures.
- Insufficient Sealing Leading to Protection Hazards: The shell failed to achieve
effective sealing. Internal critical components like circuits and sensors were long-term exposed to the experimental environment, susceptible to dust accumulation and moisture intrusion, causing electrical connection failures and signal drift, severely impacting equipment stability and experimental data accuracy. - Lack of Physical Protection Mechanisms: The shell lacked integrated impact
resistance and buffer structures. During equipment handling, mobile demonstrations, or simulated operation, bumps or falls could easily damage internal precision components (e.g., Li DAR, optical sensor modules), not only increasing maintenance costs but also substantially impacting teaching progress and course continuity.
These structural defects had become a significant bottleneck constraining the
upgrading of teaching equipment and industry-university-research collaborative
innovation, urgently requiring an advanced manufacturing solution for rapid, customized, and functionally integrated shell production.
One-Stop Solution
Addressing the above challenges, the project team abandoned traditional manufacturing schemes and adopted CreatBot's industrial-grade Additive Manufacturing (AM) technology, combined with an end-to-end digital workflow, to achieve the rapid, precise, and functionally integrated manufacturing of the shell
Innovative Manufacturing Process：
1. Precise Scanning: Accurate Data Capture
Used high-precision 3D scanning equipment to perform 0.1mm precision scans of t he intelligent inspection vehicle chassis, completely capturing 3D point cloud data of the chassis surface, component mounting points, and existing structural dimensions. Compared to traditional manual measurement, this avoided measurement errors (e.g., cumulative errors from manual caliper measurement, inaccuracies in curved surface measurement), providing a 1:1 true-to-life base model for subsequent design, ensuring perfect adaptation of the new shell to the chassis.
2. Based on 3D scan data, the reverse design team used professional software to
convert point cloud data into a 3D model, specifically addressing the original
problem.
- Appearance and Teaching Adaptability： Incorporated a "simple industrial style" design, with neat shell lines and appropriate edges/corners, conforming both to the professional image of logistics equipment and facilitating clear display of the equipment structure to students during teaching; reserved interfaces for sensors and expansion mechanisms, supporting functional expansion experiments in teaching scenarios.
- Protection and Space Optimization: Redesigned the internal space, created enclosed cavity protection for components, and designed reasonable heat dissipation holes and dust/water-proof structures to address heat dissipation and maintenance challenges
- Structural Reinforcement Design：Added reinforcement ribs and buffer structures at corners and impact-prone areas; selected PLA-CF composite material (high strength, good toughness) to enhance physical protection capability and reduce the risk of equipment damage during teaching use
3D Printing: Efficient Prototyping Equipment
Utilized the industrial-grade CreatBot D600 Pro2 HS industrial printer: Its large 600*600*600mm build volume perfectly accommodated the teaching equipment shell size, enabling monolithic printing, avoiding structural weakening and assembly errors from split-part assembly.
- Cost and Cycle Advantages：Eliminated the need for high mold costs (traditional mold opening costs over ten thousand RMB per set), completing printing and post-processing for delivery within 3 days; supported small-batch customization, allowing flexible replication if multiple equipment modifications were needed for teaching.
- Detail Reproduction Capability：Precisely printed designed details like heat dissipation holes, mounting interfaces, and reinforcement structures, ensuring 100% realization of design functions, making the new shell fully match teaching and practical requirements in protection, layout, and expandability.
