Gyroid infill as model not printing as shown

Recommended Posts

I am trying to use the gyroid infill as my model by setting walls to zero etc. I have also changed the infill line width.

I have attached a few pics one of what the print looks like in cura in layer mode, the failed print and the original model. I have tried printing this a couple of times and it has failed in the same way. I don't know if it's difficult to print or just an extrusion problem. The problems I have are that the change in infill line width isn't being followed, I set the part I want to be just Gyroid infill to 2.45mm infill line width in the per object settings and it seems to still be printing at .35mm. In places there is a perimeter wall though non is shown on the model. There are also two or three lines running through the print.

 

I have tried this on an Ultimaker 2+ and extended Ultimaker 2+.

 

Thanks.

Thanks for taking the time to have a look at the file. Is there any way to get the infill to print thicker walls? Using multiple lines for instance.

 

Thanks.

 

I tried setting the Infill Line Multiplier to a value higher than 1 and it did print multiple lines for the infill but, unfortunately, it appears to produce duplicate lines and a lot of weird travel moves so I can't recommend it. Sorry.

At the risk of sounding sarcastic (which I am really being serious), I just went with the Larger bore nozzles (0.6, 0.8. etc.) to get thicker infills.

 

However, I have not gotten a good print without some sort of shell (PVA or otherwise), even with the combing off. But I am getting nice patterns in see through objects that I like.

I don't have this option as the printer is in a makerspce. We don't have a multinozzle machine either unfortunately.

 

I think I'll have to find another way to generate the object.

How about this... take an existing gyroid stl (there's a bunch on thingiverse) and using a 3d modelling app intersect the hemisphere shape so you end up with a hemisphere gyroid model which can then be printed as normal walls/infill?

I'm using onshape and it's not possible to do a boolean operation on a mesh(stl) in onshape. I believe meshmixer can do this ? but I use linux and it doesn't run there. Is there any other way ?

For? Grapphics programs? His search would be as good as my search.

 

Printing options? Not really any more than offered already. As I said, I just started to use transparent skins or PVA, mostly transparent, to get a clean gyroid infill (Let the pattern show through). This has more to do with the limitations of how cura handles infills. I mean, seriously, not many weirdos (no offense to the OP) like me that wanna do this stuff.

 

Most salient points were made by you. But I still would investigate larger bore nozzles rather than more infill walls.

Do you have any photos of such prints to show

While there is more color here than one nozzle, the effect remains consistent:

I found a stp file of a gyroid on grabcad and I was able to do a boolean operation on that model.

Here is the result of an 11 hour print , with no supports so I have some repair work to do. It was printed in ABS so I will be using ABS slurry to repair it.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
