Texture Effects for parts of the print on S3D & Cura

Recommended Posts

This will be a fast tutorial, you need to control all the other aspects of this to understand how cool it's this.

First Create 2 objects, the Base (grey) that will have the normal settings and the Effect layers (orange). Take care that they don't intersect.

Make two process, one with the normal solid options and assign that to the base, and make other process without TOP or Bottom, and only infill, for this example Full Honeycomb works perfect

And VOILÀ! Octopus Tentacle 3D printed.

The posibilities are endless when playing with multiprocess, or different settings per object (cura). You could split the object in different sections and assign different infills, texture effects, make a part in the middle with only infill for a flexible 'like a spring' section. ETC ETC ETC.

On Cura I know this it's posible, but I just downloaded the last cura, dropped the 2 stls, and I wasn't able to merge, group or anything. So I don't know if it's a mac version bug, or the UI it's just overly complicated. So if any Cura expert want to show how this it's done in Cura, go ahead (@nallath time to make Cura shine!) And btw Nallath, HOW the hell someone selects ALL objects? Not Ctrl + A ? or CMD + A ? Shift doesn't do a think, so Shift no.. And if not, why not?

In Cura 2.1, you can select multiple objects with Ctrl-click. In Cura 2.2, we will change that to the more discoverable Shift-click, and we will also add a Ctrl+A to select all objects.

Ok, Ctrl Shift Click. Still no option to merge, group, nothing. Both objects selected

Also thanks for changing all that in the future to standard keys (standards as shift works on almost OS, illustrator, rhino, word, textedit, notepad...).

Anyway, it doesn't unlock the options

Edit. Oh weird, some combination did group that, and the options did show blank. Weeeeeird. Ok got it finally but the offset it's just bananas.

Now after adding 3 options on the per object settings, it just blocked and keep the spinning symbol... Had to force exit

Got this

https://www.dropbox.com/s/fm3guis09l2ppem/kernel.txt?dl=0

Now.. trying again.. wow this it's weird to be able to do something so simple...

Ok again, when I added a second thing (wall, top, bottom) bang

https://www.dropbox.com/s/flr76k78xpqlsat/kernel2.txt?dl=0

So... First question that comes to mind..

Why this method of adding settings? Why not just a full profile of settings per object (a real subprocess) Also... wow it's far from click-select-print. Sorry to bang on this, but it's really hell, and it hangs so fast

Pfff.. Ok trying again... I had to close Rhino to stop the hangs... Not cool to close the 3d software to print, but ok

I was able to select a different setting for the top effect, and other settings for the other part, all ok until...

Click MERGE...

And the settings banish...

So....?

I see.. Merge actually makes ONE object out of a selection... Ok, that's quite meh sorry. I see that for simple stuff like having one object from different parts, but if I can't select profiles for each part, then why I need the merge? It won't work for dual, since I can't select each part for each setting (no extruder, support, special settings). So.. Merge only 'merges a group of objects into one selectable object' ? Ok.. ok... ....

Do this please then, "Fixed Offset Groups". To create groups of object that their only common thing it's that they share the offset (and allow to keep each setting added to each part or assign a list of profiles to each part) Otherwise, this isn't posible on Cura.

Ok, you can say now, "Hey you could do it by hand!"... Ok.. Let's see what happens when I try to place the TOP part of the optopus tail where it should be (and by hand means Precision = 0)

 

First, where's the option to stop Cura from thinking for me and not allowing me to put an object above the Z 0 ?

And... There no option to adjust the X/Y/Z by numbers so I could even get close to what I do on S3D with drag, group, assign profiles to object, make gcode?

Also @ahoeben, about the Keys to press to do something. Just a suggestion:

cura.thumb.jpg.00d0b49959abd4b816d1a6af91d8ab96.jpg

List them there :Dplease?

Sorry, I was trying to be helpful. Did I say anything to deserve a rant?

Perhaps if you posted the models, we could see if they behave in an unexpected manner.

 

Not at all. Sorry if seems a rant. It was that since there's the option to select different stuff per object I thought this was gonna be so easy and fast. Sorry! I'll post the files sure. It's just 2 tentacles with a top layer of 0.2 height for the effect

I see three main problems that would need to be solved to print with this trick

- Be able to merge objects with the settings intact.

- Be able to move objects by 'numbers' to be able to move each object into their correct position, assuming that that numbers always start at 0 from the object Offset

- Be able to move objects above Z0 without the automagic adjust from cura that places them on the bed. So an extra option to remove that automatic stuff.

Thanks for the models. I will check them out tomorrow.

In the mean time, here's a model I did for experimenting with different settings in one print:

https://www.youmagine.com/designs/spire

One important bit for successfully merging two objects is that they should share the same origin.

In 2.1, the workflow would be to load both objects, and use the Per Object Settings tool to add settings (such as fuzzy skin) to one of them. Next select one of the objects and then Ctrl-click (or Command-click) the other. Now both should be selected, and it should be possible to select "Merge objects".

In 2.2 we will have improved this by quite a bit: You will be able to change settings of objects that are already merged, we have added keyboard shortcuts (Ctrl-A to select all objects, Ctrl-G to group, Ctrl-Alt-G to merge, Ctrl-Shift-G to ungroup/unmerge), and more.

Moving objects "by numbers" will also be in 2.2. There's already an option to turn off the "push free" feature, but I don't think there's an option to stop the auto-z automatically. I'll raise an issue about that.

Ok today got some time to sit on the sofa and just got the way to do this properly on Cura (on the current cura). It's quite easy but with all the new features it will just way easier.

So, the trick it's to make cura think that the second object has the same z as the other by adding an object on the Z0 that it's 0.0001 tall. It's a surface, but since it's smaller than the layer height it won't be printable. This way both separate stl has the same object that can be easily align by hand. Then you choose the settings on the octopus tail, and group them. Done

And voilà!

To make this work the align object must be on a x/y/z that's lower than any other object (on the program you design).

I saw this post this morning and gave it a quick whirl before getting ready to head out the door.

I am on Cura 2.6.2 and it worked like a charm. Now I have to dig out a cool file to run it through some tests.

However, this does point towards using some interesting infill patterns that are not currently available in Cura.

Indeed on Cura it works since they added the per object settings. For s3d they broke it on 4.0. Visually I prefer s3d over cura and for the prints I do Cura can't manage efficiently the multiple settings I need nor the surface finish. But cura is getting better and better very fast.

Oddly, when I got into this, I went full tilt with printer, supplies and software. I own S3D as well as downloaded all the others (main ones like slic3r, etc) as well as expanded my creation software and dropped a few others for creative freedom, and found Cura more to my liking. I think it is because of the time I got into it and it just 'fits'. Sorta like back in the day when people gravitated to Freehand or Illustrator based on what they felt was right for them. Both did basically the same thing, but it was more of a personal choice.

I am not disappointed with S3D. Do not get me wrong about that. I just, like, ya'know, have a teeny crush the the cute Cura damsel, fer shurrrr, dude......

But as soon as I get this print finished tomorrow evening, I have one using your technique ready to go.

It makes me want more infill pattern choices and 3D control of line direction.

Yes....I want it ALL!!!!! BWAHAHAHAHahahahaha

OK...I am finishing up the last of my vase (spiralize and Faux spiralize) prints. I went a bit nutso with the design process, Fractals and all sorts of things. 26 of them (sheesh) and mostly at 0.8 Nozzle width and variations of ideas and such.

BUT!! While I was waiting on prints, I designed this thingy based on the idea presented here. You have heard of the Faberge Eggs? Well, here is the Neotokotized egg :) Only a 95 hour print LOL :p Again, went nutso with it.....You can right click on the image and 'view image to see it full sized.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
