SubD examples and models

Well here you go, quick prepub post.
Here it is about half way, you can see how the support structure is inter-meshed with it. This particular printer, an Up Mini, doesn't allow you to turn off support fully, although you can reduce it. The supports are very delicate and quite easy to remove. But it's best to position your piece to get the least possible, or in this case the most suitable.
If I had set it square on it would have created a lot more support to fill the cube, it would have been better set on iy's point, but the tiny footprint would most likely have caused a print failure, as the connection to the 'raft' is remarkably tenuous.
And here is the finished print, just waiting to be broken out of it's supports. You can see the individual layers of filament, these can be smoothed off with a bit of a light sand.
Mind you this shape will be impossible to smooth perfectly as it's near impossible to get inside. Before you ask, it is a 50mm cube. and it took ~2.5 hours to print.
I'll try and clean it up and post a finished pic soon.

Rather than using sandpaper you could scramble it with sand in a box(not tested though - the plastic might snap :/)

Yes, a tumbler might work nicely, abs is so soft it takes very little to smooth it.
You could wipe it with acetone or hit it with a gentle flame, you could paint it or give it a thin coat of filler, the method you use pretty much depends on the finish you want.
In this case I've just given it a rub over with an emery sponge to smooth off the outside faces. The inside can stay raw.
This is just a handy demo of the results you can expect from a mid range domestic printer.
Black is so difficult to photograph, plus the camera shows far more detail that the eye sees.
You can see how on the corner my light sanding went through the shell. I printed it on the shell setting so the whole thing is actually hollow.
It is remarkably strong and nicely tactile.

VERY NICE!
Thank you for sharing. After the support structure image, I didn't expect such a clean result.

Yes Cotty, this printer has a very clever system of support. They break away very easily and the 'raft' somehow just pops off.
-
I think "little" is the wrong word here...

Since there was a little interest in printing results I did a quick cube SUbD box like the one I posted two pages back and printed it.
This is straight out of the printer. The rough bit on the top is where I pulled it off the raft, it will clean off. You can see the little gap created by JPP around the lid, but a quick sand and it should fit snugly. The faceting will also smooth off, you could subd further if you wanted it smoother. The smaller things are the more the facets show.In case anyone is wondering, it's not some weird photoshoped image, it's just the physical model sitting on a tablet screen.

Little is all relative, a few people hitting the thumbs up button is pretty big on the forum.
And as such I took it as interest. FB on the other hand can lead to expectations of hundreds or thousands of reactions, and if you don't get them it is a sure sign of little interest.
Interesting how the same word can mean different things depending on context. -
Here we go, a bit of sanding and a wipe with acetone, then another light sand and a buff.
The tiny tassel hinges took a bit of fiddling.

It's an Up Mini that I picked up used for next to nothing. The guy bought it new but never learnt to model so he got bored with it and basically gave it away. It's my home one, I have access to a bunch of much larger ones at work.
-
I'm astonished at the surface finish you got.
-
What can I say, elbow grease and a gentle touch.
-
Just a quickie. The combination of SUbD, Vertex and Quad face tools makes it so easy to shape, manipulate and select everything.

UV mapping in Wrap-R?

Some licorice?

No, by using quad face tools I easily selected the edges to create the various faces and manually painted them with the old bucket. So the colours are actual geometry.

lovely mesh...

Here's a little example of how I did the colours. Not the same model but a similar process.
