[China Instrument Network Instrument R&D] The combination of functional materials and complex shapes driven by external stimuli is a hot topic in bionic drive research.
Fabrication of Assembled Magnetic Drives with Multi-material 3D Printing and Driving Demonstration Experiments
In recent years, various hydrogel materials, alloy materials, and composite materials based on carbon nanotubes (CNTs), graphene oxide (GO), and the like have been successively applied in drive research and have been prepared similar to caterpillars and fishes. Bionic drive devices such as flowers and other complex structures. However, due to the complex shape of many bionic devices, and most of them require multiple material combinations to achieve specific functions such as driving and motion, how to build complex structures and solve assembly of multi-material components is still a challenging topic in the field of bionic drive research. .
Multi-material 3D printing advanced manufacturing technology provides a simple and easy solution. Recently, the Surface Surface Group of the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, used the advantages of 3D printing technology in computer-aided design (CAD), free manufacturing processing and device molding, and used multi-material 3D printing to build magnetic and non-magnetic parts. The sectional assembly of the assembly-free flexible actuator realizes functions such as bending, deformation and cargo transportation.
Based on the development of magnetically flexible 3D printed photosensitive resins, researchers have improved digital light processing (DLP) shaped 3D printers to enable them to freely switch between two or more photosensitive resins in the vertical direction. Double (multiple) material 3D printing technology, so as to achieve the drive device containing magnetic and non-magnetic parts free assembly one-time molding manufacturing. Mechanical testing and SEM analysis have shown that the magnetic and non-magnetic two resins have good binding force and can perform effective magnetic field driving. As a proof of concept, the researchers used this technique to print and create a gripper that can be controlled remotely and perform functional verification of capture, transfer, and release. This simple and versatile multi-material 3D printing technology will be able to expand the application of 3D printing in remote control release and flexible robots.

Excavator Bucket
CATSU excavator bucket is a large attachment used
on an excavator to scoop and move materials such as dirt, rocks, and debris.
CATSU excavator bucket typically made of heavy-duty steel and comes in various
sizes and shapes depending on the type of job it is used for. CATSU Excavator
buckets can be used for digging, grading, screen, trenching, and demolition
work. CATSU Excavator buckets commonly used in construction, mining, and
landscaping industries.
The CATSU Tiltrotator is a highly versatile and efficient attachment that works
seamlessly with various excavator attachments. Whether you need to dig, grade,
cable, rip, rake, compact, or sweep, the CATSU Tiltrotator provides exceptional
performance.
When equipped with a Digging Bucket, the CATSU Tiltrotator allows for precise
and efficient excavation work. It enhances the excavator's capabilities by
enabling 360-degree rotation and tilt, providing greater flexibility and
accuracy in digging operations.
For grading tasks, the CATSU Tiltrotator paired
with a Grading Bucket ensures smooth and precise leveling of surfaces. The
ability to tilt and rotate the attachment allows for precise grading and
contouring, resulting in high-quality finished surfaces.
When using the Cable Bucket attachment, the CATSU Tiltrotator offers enhanced
control and maneuverability. It enables operators to easily handle and position
cables during construction or utility work, improving productivity and
efficiency.
