This is a deep industry-academia-research cooperation project between CreatBot and Henan Communications Vocational and Technical College (hereinafter referred to as "Henan Communications College"). Taking the opportunity to serve the intelligent inspection robot of SMP Robotics, a world-leading robotics technology company, both parties leveraged their respective advantages in technological R&D and talent cultivation, successfully using CreatBot's large-scale industrial 3D printing technology to complete the complex, lightweight, and highly customized shell design and rapid manufacturing of the robot. This case not only validates the application value of industrial 3D printing in high-end equipment manufacturing but also explores a successful path of "industry-education integration and collaborative innovation," providing a reference model for the intelligent manufacturing industry.

Background and Challenges
With the in-depth advancement of China's "Made in China 2025" strategy, the application of intelligent robots in industrial inspection, security, logistics, and other fields has shown explosive growth. Intelligent inspection robots have become core equipment for ensuring the safety of modern facilities and improving operational efficiency due to their ability to operate autonomously, perceive accurately, and work continuously 24/7. Their application scenarios widely cover:
- Industrial fields: In complex environments such as factories, power stations, and petrochemical plants, they replace manual labor for equipment status monitoring, thermal defect identification, gas leak detection, and meter reading, effectively avoiding operational risks in high-risk environments.
- Infrastructure: In large public facilities such as data centers, airports, and subway stations, they perform 24-hour security patrols, personnel intrusion identification, and fire warning, building a three-dimensional security system.
- Energy industry: In outdoor energy bases such as photovoltaic power plants, wind farms, and substations, they automatically complete photovoltaic panel inspections, equipment checks, and line inspections, significantly reducing maintenance costs.
As an internationally renowned ground robot developer, SMP Robotics has deep expertise in this field. Its products need to operate stably in various harsh and differentiated environments, thus placing extremely high demands on the lightweight, environmental durability, and rapid customization capabilities of core components such as shells.
During the research and development of the intelligent inspection project at Henan Communications Vocational and Technical College, the shell of the teaching robot equipment mainly had the following problems:
1. Structural Design and Aesthetic Defects: The original shell had a rough appearance, lacking standardized industrial design, which did not meet the technological sense and standardization that professional inspection equipment should have, affecting the intuitiveness and professional perception of teaching demonstrations and making it difficult to effectively support students' structural cognition of modern intelligent inspection equipment.
- Insufficient sealing leading to protection hazards: The shell failed to achieve effective sealing, causing internal circuits, sensors, and other key components to be exposed to the experimental environment for a long time, which was susceptible to dust accumulation and moisture intrusion, resulting in electrical connection failures and signal drift, seriously affecting equipment stability and experimental data accuracy.
- Lack of physical protection mechanisms: The shell did not integrate impact resistance and buffer structures. During equipment transportation, mobile demonstrations, or simulation operations, collisions or falls could easily cause damage to internal precision components (such as laser radar, optical sensor modules, etc.), which not only increased maintenance costs but also had a substantial impact on teaching progress and course continuity.
These structural defects have become a major bottleneck restricting the upgrading of teaching equipment and industry-academia-research collaborative innovation, urgently requiring a fast, customized, and functionally integrated shell solution through advanced manufacturing methods.
One-Stop Solution
To address the above challenges, the project team abandoned traditional manufacturing solutions and adopted CreatBot's industrial additive manufacturing (AM) technology combined with an end-to-end digital process to achieve rapid, precise, and functionally integrated manufacturing of the shell.
Innovative Manufacturing Process:
Precision Scanning: Accurate Data Collection
High-precision 3D scanning equipment was used to scan the body of the intelligent inspection vehicle with an accuracy of 0.1mm, completely capturing 3D point cloud data of the vehicle body surface, component installation positions, existing structural dimensions, and other information. Compared to traditional manual measurement, measurement errors (such as cumulative errors in manual caliper measurements, inaccurate curved surface measurements, etc.) were avoided, providing a 1:1 real reproduction of the basic model for subsequent design and ensuring perfect adaptation of the new shell to the vehicle body.

Reverse Design: Perfect Prototype Replacement
Based on the 3D scanning data, the reverse design team converted the point cloud data into a 3D model through professional software to solve the original problems.
- Appearance and Teaching Adaptability: Integrated with "simple industrial style" design, the shell has neat lines and moderate corners, which not only conforms to the professional image of logistics equipment but also facilitates clear display of the equipment structure to students in teaching; reserved interfaces for sensor and expansion mechanism installation to support functional expansion experiments in teaching scenarios.
- Protection and Space Optimization: Replanned internal space, designed enclosed cavity protection components, and opened reasonable heat dissipation holes and dust-proof and waterproof structures to solve heat dissipation and maintenance issues.
- Structural Reinforcement Design: Added reinforcing ribs and buffer structures at corners and collision-prone parts, and selected PLA-CF composite materials (high strength, good toughness) to improve physical protection capabilities and reduce equipment damage risks during teaching use.

3D Printing: High-Efficiency Forming Equipment
Industrial-grade CreatBot D600 Pro2 HS industrial printer was used: its large forming space of 600*600*600mm perfectly matched the size of the teaching equipment shell, enabling integrated forming printing and avoiding structural weakening and assembly errors caused by split splicing.
- Cost and Cycle Advantages: No need for high mold costs (traditional mold opening costs tens of thousands of yuan per set), printing and post-processing can be completed within 3 days for quick delivery; supports small-batch customization, flexible replication if multiple equipment modifications are needed in teaching.
- Detail Restoration Capability: Precisely printed details such as heat dissipation holes, installation interfaces, and reinforcement structures in the design, ensuring 100% implementation of design functions, making the new shell perfectly match teaching and practical needs in terms of protection, layout rationality, and scalability.
