Textured Surfaces ?  

RE: Textured Surfaces ?

It is possible.  I printed a dimpled golf ball, but you need to remember the limits of the precision of the machine when designing the product in CAD.

RE: Textured Surfaces ?

Try using "Hilbert curve" for the Top fill pattern. 
That gives a nice texture IMHO.

I know that Cura has the "fuzzy skin" setting if you're looking for something in a slicer. In one of their recent YouTube live events I thought the Prusa guys mentioned possibly adding a similar feature to PrusaSlicer but it would be a while if they did. Hope they do add it though - seems like a good way to add grip to mechanical/functional prints. 

Here's the Cura slicer settings for reference:  

RE: Textured Surfaces ?

Some time ago (a year or so) I remember some designer on one of the 'usual suspect' sites had some models that had textured surfaces as part of the drafting process.  I don't remember how this was done or if the designer said how it was done, but I know that it's been done and can be done.  I also don't know how this looks in the various dimensions when printed.

It may be something similar to what's discussed here: https://forum.freecadweb.org/viewtopic.php?t=16897

RE: Textured Surfaces ?

You can use an image in software like blender to apply a 'bump map' to a surface.  That raises /lower the surface depending on the colour of the image.  That type though is then part of the actual model when applied so needs a fair amount of polygons to do rather than being some sort of post processing done by the slicer.

You got my curiosity on that one.  I've seen that option but never really thought about it.

I was just preparing an internal support piece, something that's not seen and not critical, so I figure WTF might as well see what it does.

Here's what it looks like in the Cura preview:

And hopefully you can see enough detail in this to see what it does when printed:

You can adjust it somewhat.  This piece is not going to be seen, so it's NBD.

RE: Textured Surfaces ?

I've seen the cura fuzzy skin used on a replacement hacksaw blade handle which I thought was a good use for it.  Struggling to think of other practical uses though.

RE: Textured Surfaces ?

It reminded me of the texture on some of those foam pads used in shipping containers.

RE: Textured Surfaces ?

Not sure how much texture you want, but this technique might be of interest https://www.prusaprinters.org/prints/38953-real-birch-tree-texture-applied-to-a-lamp-shade there is a link on that page that explains the technique in more detail. I have to say that I've not printed the shade or tried to replicate it, so can't vouch for how easy it is to get good results!

I would use the subdivision and displacement modifiers of Blender to edit the stl.

The quirky KISSlicer had a bumpmap feature that could be applied to a selected surface. It was an interesting idea. Unfortunately, KISS doesn't seem to be under much active development, and is quirky enough that it's a chore to use. It's a shame because it also has very interesting Z-seam handling features.

Thanks guys for your thoughts.

I liked the look of the Cura Fuzzy Skin so i downloaded Cura only to find there isnt a profile for the Mini ??

Unless someone knows better ??

RE:

Old post, but I've been reviewing this and searching for the best way. Right now I'm looking into IdeaMaker based on a video by Makers Muse ( ). I don't particularly care for printing using IdeaMaker but I'll try to see if I can export the STL with the displacement already applied to open it into PrusaSlicer and print from there. I'll come back with the results.

Hopefully in the future we'll have a similar option in PrusaSlicer 🙂

RE: Textured Surfaces ?

Nope, didn't work, IdeaMaker doesn't allow you to export, it applies the displacement directly to the gcode.

I found all of these posts about different techniques, velocity printing, apply displacement maps via Blender, etc. I want to imitate wood grain btw.
