I don't think it ever work the way you are describing, but then again perhaps I misunderstood the behavior you want.
It's not possible to print a part in Cura where half of the part has fuzzy skin, but there is only a single wall going around the whole object. The fuzzy wall will never be connected to the non-fuzzy wall.
Or is that not what you mean? Could you please clearly describe exactly how you want your object to be printed?
-
You can force the slicer to do almost exactly what you want if you use surface mode and extrude that drawing into 3D walls.
I must say I don't really understand your drawing, though. I'm not sure what the circle is.
It's better to not generate vertical protrusions. You can generate horizontal protrusions and right above it horizontal protrusions in another direction so that those protrusions connect to each other so that they cause interlocking.
I can share some figures of this idea later.
-
Actually I am currently working on some features to automatically generate interlocking structures for making TPU-PLA bond better.
Currently a good strategy might be to just model the models with an overlap. Cura already generates an alternating structure where the layers of TPU and PLA are interwoven within the region covered by both models.
I'm not 100% sure what you mean by 'strong slicing'. Are you referring to the problem that the Tough PLA is inside the hole and outside the model, but it is disconnected from each other?
Any criteria to take into account for generating the best kind of interlocking are welcome!!

Aha.
In that case you may want to try fiddling with the settings Remove Mesh Overlap and Alternate Mesh Removal.
If you turn those off you might get a bit of overextrusion - depending on how much the models overlap.
With the settings turned on you can really overlap the two models as much as you want and Cura will generate an interlocking pattern to fuse the two together quite well.
-
Perhaps you should first do a nozzle offset calibration then.
I haven't seen this problem in a long while. Are you running the latest firmware?
-
In order to export you do:
File > Export > Choose file type STL.
-
What's not to understand? Just follow these steps in Cura:
- Export the models on your build plate to STL
- Delete all models from your build plate
- Load the exported STL onto the build plate.
-
In Cura 3.6 you have jerk control and acceleration control enabled, so the requested speeds are different. In 3.6 you set the jerk to 20 mm/s, but in Cura 4.5 it is set to 8 mm/s by default.

16 hours ago, Oliveros said:
Try to unhide some settings, like under speed, you have 2 settings visible in 3.6 and 1 on the other one.
Just unhide all the settings and find what's consuming all the time, I believe there's a way to see the breakdown of what is consuming time.
Yeah. Just hover your mouse over the (i) icon next to the print time.
-
Did you use the same settings in both versions? Or did the default profile for your printer change?
Could you upload the project file please? I could have a look at it.

In the second stage of manual bed leveling there is supposed to be a 0.1mm gap. You're supposed to put a normal A4 paper or calibration card in between and feel a bit of resistance.
First stage = 1mm (or less), second stage = 0?1mm (accurately).
-
Yes there are various testing stages and testing teams. However, software is complex and you might be experiencing an issue that nobody at Ultimaker ever experienced. Your case might be quite rare.
Please try a firmware reboot to factory settings.
If that doesn't help them contact your reseller.
What ever you do don't touch the internal circuitry. Some elements can store a deadly charge even when the machine is not connected to the outlet any more.
-
Perhaps the new print time estimation is more accurate because the machine acceleration and jerk in Cura reposent the real values in the firmware of your machine.
Diss you ever compare the time estimates to the real print time?
-
Just adjust your bed leveling a tiny bit. It looks like on corner of your bed it a bit too high. The printer won't be able to fit eh required amount in there because the bed is too high and the plastic wil start to bulge up.
I think that might solve your problem.
-
The prime blob that your printer performs might simply be part of the start gcode. Google how to edit that and look at the reprap wiki for gcode to understand what the codes in the start gcode do exactly.
If it's not in the start gcode than the firmware of your printer might decide when and how to do the prime blob. In that case I can't help you.

If you want to Union in Cura then just export to STL in Cura and open that file again in Cura.
-
What? I don't understand. If you have overlapping volumes in one model they will be combined automatically.
If you have multiple models you can combine them into one by saving to STL and importing that again.
You don't need to repeat this process. You can just open the saved STL again.
-
Have you tried the suggestion of my last post?
-
You could edit the setting top/bottom angles and Infill Angles. Those relate to the stiffness in a specific direction.
-
That's not how Union overlapping volumes works. It's a bit hard to explain, but here we go.
Union Overlapping Volumes is meant to solve problems inside a single mesh, not the interaction between two meshes. If you have two mesh files than their interaction is governed by Remove Mesh Intersection. There is no option to union, because the two meshes might have different settings in the per-object settings menu.
If you want to union them you could export those two models as a single STL file and import that again. Then the overlap is within the same model and the Union Overlapping Volumes dos its magic 😉

I verified that the Schwartz P also has the same shape of the overhang angle occurrence plot.
Are there more TPMS which are defined by an implicit function?
-
According to my analysis the Schwartz D is exactly as printable as the gyroid, with normals concentrated around 45* overhang. The Schwartz D surface is definitely more stiff, though, seeing as it has straight lines in it.
Can't find an easy stl for the Schwartz P surface for my automated analysis. Perhaps I will have to generate it myself in MATLAB just like I did for the gyroid.

I've been studying triply periodic minimal surfaces (TPMS) quite a bit.
There are numerous other surfaces. This site has a very extensive list:http://facstaff.susqu.edu/brakke/evolver/examples/periodic/periodic.html#gyroid
One important criterion is that they have no overhang, but even gyroid surface violates the overhang angle.
We might want to relax the criterion of being minimal, and alter the gyroid slightly in order to satisfy overhang constraints.
However, that would require some mathematical trickery which I haven't delved into yet.
Another idea is to rotate the patterns if there is one orientation in which there is considerably less overhang.
@Noisettetbou Please share any results you found. I am very interested.
It seems to me the Schwarz D is very anisotropic; does it have those straight diagonal lines only in one direction?

Ultimaker TPU95 Oozing From Print Head

Pile up in blobs? Perhaps there's something wrong with the temperature. Are you sure the machine recognizes the material as TPU? Are you sure you have selected TPU for the correct extruder in Cura?
