Producing Custom Parts

Manufacturers need to manage their supply chains efficiently to ensure they can quickly access custom or replacement parts for their robotic solutions. One way they do this is by keeping an inventory of spare parts. However, many are now turning to 3D printing technology to reduce their reliance on suppliers.

Instead of waiting for parts to be delivered, manufacturers can simply print them using 3D printers. This allows them to create the needed parts or components in just a few hours, using a digital file. Engineers can then refine these parts by testing out different versions of the 3D-printed components. This approach saves time and offers more flexibility in the manufacturing process.

Manage Materials More Efficiently

Like many other companies, those creating custom robotic solutions are looking for ways to reduce the costs of materials. By trying out different materials and using 3D printing technologies, manufacturers can strategically place materials only where necessary. This not only allows for experimentation with various materials but also helps in cutting production costs by minimizing both material usage and waste.

Delivering Custom Robotic Solutions

Robots are used in various industries, and nowadays, many organizations create customized robots tailored to their specific needs for automating processes. Engineers play a crucial role in designing and developing these robots, ensuring they possess unique features and top-notch performance. The use of 3D printing technologies has become a valuable tool in this process.

Engineers leverage 3D printing to design and test prototypes of robots intended to automate tasks that are considered dirty or dangerous for humans. This approach allows them to fine-tune the robotic solutions to meet the precise operational requirements outlined by the client. Moreover, 3D printing enables the rapid production of customized robots based on approved prototypes, ensuring a quick turnaround.

In the creation of these custom robot solutions, enterprises utilize 3D printers not only for designing the robots but also for fabricating the actual design. This integration of 3D printing technology streamlines the development process and contributes to the efficient delivery of tailored robotic solutions.

How selective laser sintering is helping the robotics industry ?

Customization for Robot Design: Robots often require specific components tailored to their intended tasks and environment. SLS allows for the rapid prototyping and production of custom parts with intricate geometries, enabling robotic engineers to design robots optimized for their intended applications. Whether it's grippers, joints, or frames, SLS facilitates the creation of components that fit the exact specifications needed for a particular robotic system.

Lightweight and High-Strength Components: Efficiency and performance are critical in robotics, especially in applications like mobile robots or exoskeletons. SLS enables the fabrication of lightweight yet durable components, which are essential for improving mobility, reducing energy consumption, and extending battery life in robotic systems.

Complex Internal Structures: Many robotic components require intricate internal structures for functions like routing cables, housing sensors, or providing structural reinforcement. SLS can produce parts with complex internal geometries, allowing for the integration of such features directly into the components themselves, streamlining assembly and enhancing functionality.

 

Reduced Assembly Complexity: Traditional manufacturing often requires assembling multiple parts to create a single component, leading to increased assembly complexity and potential points of failure. SLS allows for the creation of consolidated parts, where multiple features or functions are integrated into a single component. This consolidation reduces the number of parts needed for assembly, simplifying the manufacturing process and improving reliability in robotic systems.

On-Demand Production and Inventory Management: The robotic industry often deals with fluctuating demand and evolving design requirements. SLS supports on-demand manufacturing, enabling robotic companies to produce parts as needed without the constraints of traditional manufacturing processes. This capability reduces inventory costs, minimizes lead times, and allows for greater flexibility in responding to market demands and design iterations.

Material Flexibility and Innovation: SLS can work with a wide range of materials, including various plastics and metals. This flexibility enables robotic engineers to experiment with new materials and composites, fostering innovation in robotic design and performance. Whether it's exploring new materials for enhanced durability, heat resistance, or conductivity, SLS provides the versatility needed to push the boundaries of robotic technology.

In summary, selective laser sintering is helping advance the robotic industry by enabling the rapid prototyping, customization, lightweighting, and innovation necessary to develop highly efficient, reliable, and capable robotic systems.

Case Studies 

1. End-of-arm tooling through 3D printing (EOAT)

Robotic end-of-arm equipment such as vacuum grippers, jaws, and other devices are ideal uses for the design flexibility that 3D printing provides. With the use of 3D printing, functional grippers with intricate elements like live hinges and air lines may be constructed in a single piece and assembled without the need for assembly (see below). Weight savings can be achieved by using topology optimization techniques or just by using plastic instead of metal for robot tooling. This keeps more of the robot's payload for the parts. Using 3D printing to bring robot tooling in-house is another cost-effective way to produce these things, maybe reducing time as well.

2. Off-Robot Accessories Printed in 3D

Naturally, the robot end effector is just a single component of the larger system required to automate a certain task. It could be necessary to make custom trays, jigs, fixtures, and other items in order to collect parts after they have been treated or to serve them to the robot precisely. Once more, 3D printing offers a quick and easy method for developing innovative solutions around robot automation, which may be completed internally using a reasonably priced polymer printer.

3. Exoskeletons

The skeleton that bends! UC San Diego Ph.D. candidate James Jiang created this zoomorphic robot. The robot's body is entirely 3D printed, and it mimics muscular elasticity by utilizing the material's flexibility.
This robot moves its legs back to their original position by applying the compliant mechanism principle, which does not require any springs, joints, or pistons as rods and screws do. The material's own spring is its flexibility.
This results in a more natural stride that mimics the movement of a real creature, as well as a reduction in material costs. Additionally, since you don't have to take into account the movement of independent joints, programming is made simpler.
