This is done by shrinking some areas and expanding others, to effectively unstretch and unroll the model. Optimize movements as much as possible to decrease print times. I am glad I found this blog. The main advantage of this infill type is that while extruding it never directly crosses a previously extruded line on the same layer. The areas that experienced the most shrinkage in the flattening process should experience the least shrinkage when the fabric contracts after printing, and the regions that experienced little to no shrinkage in the flattening process should contract as much as possible in the fabric representation. This means that the shapes are limited in the amount areas can stretch relative to one another. Extrinsic means that it requires the surface to be embedded in a 3D space to measure. Traditional Hexagon Infill.

It starts with a normal. In order to ensure that our hexagon patterns are strong, we needed to make a number of considerations specific to 3D printing: Print the longest connected lines possible to create continuous lines.
Properties of a surface can be described as intrinsic or extrinsic. MatterControl Tutorials: Beginner Get started with this beginner MatterControl tutorial for basics on how to start initial operations like slicing and printing.
Hexagons are nice because they are one of only a few polygons that can tile a 2D space, and when you squint at them they look kind of like circles. Intrinsic properties are in a way more fundamental to a surface. Optimize movements as much as possible to decrease print times.

There is an interesting themed collection of 3D printed hexagons on Thingiverse. María Loureiro aka @tecnoloxia started a project named @Hex where she.
The printed plastic inhibits the contraction of the surface, guiding it to take a shape upon release.
This can be a difficult distinction to understand. More strength can be achieved by using a triangle infill but it also uses more material in the same amount of space. This process is reminiscent of the Floraform projectwhich uses differential growth in different regions of a surface to generate beautiful 3D geometry.
Topics 3D Design. Here is a 3D layer view of the completed hexagon printing. For instance, if you take a piece of paper and roll it into a cylinder, you have only created extrinsic curvature.

Optimize movements as much as possible to decrease print times.
We were also constrained by the fabric, which can only stretch about 1. The printed material resists contraction, so when we release the fabric after printing, the nose wants to stay the same size more than the material around it, and that material squeezes in, causing the nose to pop out. Triangles provide the highest strength infill option for 3D printing, but maximum strength isn't always needed. Both the flattened and 3D representations of the shape are put into an openFrameworks program, where we compute the amount of shrinkage each triangle in the model experiences.

This is as opposed to mean curvature. |
With shorter legs and less empty fabric, we found that the fabric would contract into domed, barnacle-like shapes. Notify me of new posts by email. Thank you for sharing this helpful information. Grid Infill Pattern.

Triangles provide the highest strength infill option for 3D printing, but maximum strength isn't always needed.
The most important quality of hexagons, and why they appear so frequently in nature, is that they achieve the best balance of strength and material use. ![]() Geometry of a Hexagon. Grid, lines, and concentric patterns can fill specific aesthetic or other needs, but aren't always the best option for rigidity. Once the fabric is released from tension, any areas covered by 3D printed material are unable to contract, but the rest of the fabric wants to shrink. This is one good example of 3D printing and its capability to print complex structures! |
Optimize movements as much as possible to decrease print times.
To get from a process that flattens a shape to one that induces a shape on a flat surface, the way shrinkage is represented has to change.
This project builds upon several projects that have dealt with printing on pre-stretched fabric before. Extrinsic curvature is bending while Gaussian curvature is distortion.
The reason hexagonal patterns are prevalent in nature is due to their efficiency. Print each successive layer at different angle directions to give strength in all directions.
