What are the advantages of gyroid infill?

I've seen a few print time-lapse videos lately which use gyroid infill: wavy lines, which deform across layers so that the waves end up alternating between the two axes. Other than making the time-lapse videos look much cooler, what are the benefits…

Different infill in the same part

I´ve have read an article to change different pattern depending on amount of layers, but my question is if is possible to have different infill in the same part? For example: Base: has the infill of 25 % but the same base has some tabs for screws…

Choose infill percentage

Since I'm running a 3D printing facility of an engineering school, students are always wondering how much infill percentage affects the stiffness of the part. I know that it is impossible to get a numerical solution for this question, but maybe…

Slic3r - Can I add new infill patterns?

Slic3r comes with a handful of infill patterns/algorithms, including Rectilinear, Hexagon, 3D Hexagon, Concentric, and Hilbert Curve. Are there any patterns/algorithms already made and available that I can add to Slic3r? If so, how can I add them…

slic3r: Can I vary the infill percentage for different heights of my model?

How can I vary the infill percentage for different layer heights of my model? Context: The bottom part of my model needs about 20% infill. The geometry of the top part of the model (mostly cones of various sizes) prints well with 0% infill and is…

Unidentified problem in printing

I have printed the XY resonance, Z resonance, bridging performance and the negative space tolerance test, from Makezine (can be found here), and I have encountered the following errors in the prints. Z resonance test: The layers are shifting as the…

Does Cura have an algorithm for any infill percentage or does it just have specific patterns?

Looking in the Cura interface, I can set any whole number 0-100 for the infill percentage. Does Cura have an algorithm to calculate a pattern for any of those possible values, or does it have a few patterns where it selects the closest one?

Infill pattern comparison

I'm relatively new to 3d printing, and wanted to get a few things understood. Firstly, I am unclear on how Hexagonal infill is stronger than, say, diamond pattern. Can anyone explain how the different shape causes the structure to be stronger? I…

How to add internal supports/localized infill, preferably in Cura?

I'm currently designing a very large and complicated model, because it's large and should be strong enough completely hollow I want to print it with no infill to save material. However, there are some points in the model where there are indentations…

Uniform squishy infill

I try to print a stamp with flexible filaments. The problem I encounter is that the filament is flexible, but not soft. This leads to small differences in height to parts of the stamp not working. One solution would be to add a small 'cushion' to…

Infill is rough - how to enhance?

My i3 MK3 is printing very well for solid parts of an object, but it messes up with infill. As you can see in the image, the infill is broken into pieces and bends to that the surface becomes rough and the nozzle touches it next time it moves…

Square and parallel infill patterns

I don't know how to word this right now but I am going to try my best... moving on! So I was playing with my slicing software (Craftware) and I was looking at two infill patterns, Square and Parallel. When looking at strength, print quality, and…

FEA in 3d printed solids

I would like to get a pretty accurate method to do finite element analysis (FEA) on my 3d designs considering the infill. I use Autodesk Inventor to design parts but the FEA can only be applied to a solid body (100% infill). Does anyone know…

Do Cura's self-crossing infill patterns account for excess material from self-crossing?

As far as I can tell, Cura's infill patterns which are self-crossing, such as triangles, don't do anything special to account for extruding material over the crossing points multiple times. In theory this should produce either a blob around the…

Infill failure when printing larger prints

I'm new to 3D printing an I just got a Creality Ender 3 and I think I'm getting some good results with small prints. However, now that I'm trying some bigger prints and I'm running into infill material excess. In the picture below I just printed a…
