Cura Type A’s Infill Generator Proves to Enhance 3D Printed Objects

3dp_ProMate_type_a_machines_logoLast month, while my colleagues from the 3DPrint.com team were soaking up the sun at RAPID 2016, back at home we reported on the new methodologies for generating internal structures that were unveiled by Type A Machines. Their Cura Type A software, which is currently available for download as a public beta release, has been enhanced with new features that provides increased access and efficiency for generating internal geometries and infills within your 3D prints. Type A Machines refers to the inner-workings of a 3D object as ‘internal structure’ rather than infill, and the change in name lends credence to the fact that these features are a true breakthrough in 3D printing software.

The two new features of their software that deal with enhancing internal structures are called Absolute Dimensions and 3D Internal Structures, and thus far, they’ve proved to help create higher quality 3D printed parts. Cura Type A internal structure process allows the 3D designer to set the precise distance between rows and columns of the object’s infill, essentially defining the infill in absolute dimensions. This process creates a ‘true’ 3D structure, and enables the 3D printed object to become more resistant to stress, while simultaneously using less material on the infill. Not only does the software enable more accurate dimensions, it also utilizes a unique twist on the cubic shape within the structure.

Instead of defaulting to a grid of stacked squares, triangles, or hexagons that are typically layered within the structure of your model, the Cura Type A software will generate an infill of cubes turned over on their sides, lining the infill along the perimeter of the 3D printed object. Once this modified cubic pattern is instilled into the 3D object, it may appear as a series of awkwardly set triangles or hexagons, but in reality, this unique infill forms a true 3D structure.

To me, this enhanced internal structure was best described in a recently published Hackaday article, which compared traditional infill generation and Cura Type A’s enhanced version as if they were graphite and diamonds, respectively. Although they’re both composed of the carbon element, graphite has thin layers of graphene that make it a weak material, while a diamond is internally a true 3D structure and one of the hardest materials on our planet.

Cura Type A isn’t the only software making an attempt to enhance the internal structure of 3D printed objects; for instance, Slic3r has a 3D Honeycomb infill feature developed last year. This Slic3r feature generates an infill pattern that varies across the Z axis rather than repeating the same shape throughout all the layers, which enhances the properties of the internal structure similarly to the Cura Type A features. All in all, these improvements in 3D software are just as important (if not more so) than advancements in 3D printing hardware. In order to truly optimize the 3D printing process, we must first ensure that the insides of our 3D models are as structurally sound as possible.
