As a popular planar motion mechanism, Core XY structure is widely used in 3D printers and writing robots for its low cost and high efficiency. However, in the pursuit of efficiency, the compactness of the structure has also become the focus of designers. This paper will discuss the compactness of Core XY printer structure and its optimization method.

The basic principle of the Core XY structure is to achieve the planar motion of the print head by driving the motion of the X axis and the Y axis respectively through two vertically arranged synchronization belts. The design is elegant, symmetrical and ingenious. However, in the traditional Core XY design, the cross part of the synchronization belt cannot pass directly through each other due to the width problem, which needs to be solved by adjusting the height, which undoubtedly increases the complexity of the structure and affects the compactedness.

An innovative solution to this problem is to reverse the synchronization belt.

By laying the belts horizontally so that they overlap back to back, friction does not interfere with each other's movements under tight conditions. This design not only allows the two sets of synchronous belts to be placed at the same height, simplifying the design and construction process, but also reduces costs because cheaper flat idlers can be used in part.

In addition to the method of twisting the synchronization belt, there are a few other tricks that can be used to improve the compactness of the Core XY printer.

For example, optimizing the layout of idlers and motors can further reduce the overall volume. In the choice of materials, the use of lightweight high-strength materials, such as carbon fiber or aluminum alloy, can not only reduce the weight, but also maintain the stability of the structure. In addition, integrated design is also an effective means of increasing compactness, integrating multiple functional components together, reducing the number of independent components, and thus reducing the space footprint.

Another important aspect of compact design is thermal management.

3D printers will generate a lot of heat when working, and if the heat dissipation is poor, it will affect the print quality and equipment life. Therefore, it is necessary to fully consider the heat dissipation problem in the design, and rationally arrange the heat sink and fan to ensure that the heat can be effectively distributed. This not only helps to improve the performance of the printer, but also further reduces the size of the device.

In addition to the above hardware optimization, software algorithm improvements are also key to improving the compactedness of Core XY printers.

By optimizing the motion control algorithm, the empty travel of the print head can be reduced and the printing efficiency can be improved. In addition, the advanced path planning algorithm can minimize the printing time while ensuring the printing quality, thereby indirectly improving the compactness of the structure.

In practical applications, the compact design not only helps save space, but also reduces transportation and installation costs. For home and small business users, compact 3D printers are easier to place and use, with higher practical value. At the same time, the compact design also helps to improve the portability of the device, making it more suitable for mobile office and field work scenarios.

The optimization of compactness of Core XY printer is a complex and interdisciplinary problem, involving mechanical design, material science, thermal management, software algorithm and many other aspects. Through innovative design and method application, the equipment volume can be significantly reduced and the space utilization rate can be improved on the premise of ensuring the performance. In the future, with the continuous progress of technology, Core XY printers will become more compact, efficient and intelligent, providing users with more convenience.
