Ultimaker 's official 3D slicing software, Cura 4.3 beta, is available for download today at Ultimaker.com ! It's compatible with Windows, Mac, and Linux, allowing pioneers to immediately try out the latest 3D slicing features. Here are the key new features of Cura 4.3 beta:
The new version of Ultimaker Cura will support more 3D file formats, making it easier for users to use CAD software, 3D scan images, and 3D modeling files in Cura slicing software. Examples include common formats such as COLLADA, GLTF, OpenCTM, and PLY. Furthermore, downloading plugins from the built-in "Marketplac" will provide even more additional support.
While the "Rotate" or "Land Flat" functions on the left side could previously aid in positioning, they could be difficult to determine the contact surfaces when dealing with complex structures. The new "Align" function solves this problem with a single click. Simply select the 3D printed surface you wish to align, check the box, and it will automatically align.

Precise control over the details of 3D printing can improve stability. The new feature allows you to select the angle of the lines supporting the grid. After entering the desired line angles, Ultimaker Cura will print the supporting grid at these angles throughout the 3D printing process.
Z-axis seams will be easier to control, and a drop-down menu has been added to "Custom" mode for placing Z-axis seams in the model.
Because small objects may have insufficient contact surface, making adhesion difficult, the 3D printed substrate may separate due to tension. The new version will provide printing functionality for small objects, especially small objects with holes. After Cura calculation, the 3D printing speed of such objects will be slowed down to reduce the impact of tension.
The new version allows users to choose to distribute the starting points of the fill lines at random locations instead of keeping them on the same Z-axis seam. This feature helps to distribute the intensity of the material more evenly, reducing directional errors and their impact. However, it will slightly increase printing time because it increases the movement of the print head.
Ultimaker Cura is the world's most widely used 3D printing slicing software, officially developed by Ultimaker . It is constantly updated, completely free, and also supports other external 3D printers . When used with Ultimaker 3D printers and cloud systems, it also offers additional functions such as multi-control system operation, remote printing, and expansion with add-ons. Start using industrial-grade Ultimaker 3D printers now and enjoy the full range of features offered by this emerging equipment.
