I was not going to put this on my machine yet until I saw the write up on this gyroid pattern. This is a screen capture of a of this model using the gyroid & the rectangular 20% infill. Since this is the model I was currently printing, decided to see the time difference in printing. I will have to try it on a more useful part next.
Pronterface shows it actually being a little less print time, but uses more filament.

The paper they got the idea from is a whole different scale. I like the idea of 3D fills but I haven’t played with them to know how they function but the idea makes a ton of sense to me. That one seems like there could be some overhang issues though?
This gyroid fill should not shake your printer as much as it does not have as many start & stop bead lines of plastic per layer as these 2 screen shots show. I am going to print this effector & see how it works.
For the last few months, I’ve been compiling their almost daily commits to come to this alpha version and I have not once thought of rolling back a single day. They are really working on this program. One thing I really like is the standard settings that you can’t overwrite. Another great new feature is that you will now be able to upgrade the program from within Slic3rPE. I just got done printing a huge 21 hour print on my MK2s using their linear advance settings and it came out perfect! It is a vortex dust separator for my shop vac…which is connected to my MPCNC. :-)[attachment file=60125]
I am about half thru printing this 2+ hour print job with the gyroid fill & the printer sounds pretty normal. I did hear a strange noise when in the other room, but think that was a woodpecker outside pecking on something other than wood.
I have just been putting these different versions of the slic3r in separate folders, so I can easily go back to another version if I do not like the current. Think I can get rid of some of those folders now as I just realized I have 10 separate folders now. I too, have not had a need to go back to a previous version yet. I have only used the released versions so far.
I’ve been using cubic for an infill pattern because it’s faster. I used to use 3d honeycomb, but on dense infill it shakes the crap out of the printer. I’ll have to download this version, but at the moment I don’t have anything to print.
After looking at a couple of the cube prints with the infill exposed, it occurred to me that using this pattern on feet for a printer might make a very good vibration damper. This seems like this would dissipate the vibration in all directions throughout the foot. Here is an image showing the idea. I printed the cubes with 0 perimeters, 3 bottom layers & 0 top layers and 10% & 20% infill. The foot was printed with 20% infill, 0 perimeters & 3 top & bottom layers. Not sure whether I should add a single perimeter around the damper or not. I was also thinking of adding a solid layer every so many layers also. I am going to make the feet taller, but wanted to make sure they fit first. Any thoughts on this idea?
Sorry I can’t add much to the conversation on this one, I think it all comes down to the hardness of your material. Some could possibly make it worse I would think.
Side note, I never thought to try a perimeter value of 0. Cool!
Seems like you dont want any flex there. Dampening isn’t as important as rigidity. If you managed to put the workpiece and spoil board up on dampening feet, that would be fine, unless you hit their natural frequency.
That is pretty interesting. I have seen a couple of his other videos. I might have to try a big concrete paver under my makerfarm prusa. I changed the wood Y back plate & front plate a while back to a plastic part & it made a big difference in noise level. I have it sitting on cork pads now.
I found that accelerometer analyzer for android & it works pretty good. I gave up on the idea of using feet for the printer after seeing that video, but am now looking at redesigning my y-axis endplate & printing that with the gyroid pattern. It just seems like that will dissipate the vibration in all directions with that infill. I have been wanting to change the way the belt tensioning works on my y-axis for some time anyway, so it is a good time to try this.
