I bought a One-Up off Amazon a few weeks ago, total cost including shipping NZ $350, just under the amount where GST kicks in. Purchase and delivery were hassle-free and it arrived in less than two weeks. I peeked inside the box and it was filled with lots of impressive-looking bits and pieces and motors and stuff. Can't say much more about it yet because it is a Christmas pressie and hasn't been opened yet.

I think3D printer needs those who enjoy modelling (like trains, cars, aircrafts, ships). It allows to design many parts on a PC and print them instead of searching them on all stores around.
It also good for home/interior designers. For example, after I changed car stereo, I've got ugly hole around it, because new stereo is smaller than old one. with 3D printer I can make frame that will hide this hole.
Also it's good for DIYers of many kinds. 

Basically, If you periodically think "oh, if I had 3D Printer I would just print this detail" then you need it :)

It would be nice if manufacturers got on board and let you print your own replacement parts for appliances.  Imagine the warehouse space they could save if they didn't have to keep parts for X machine for Y years.

I've just got myself a 3D printer... a second-hand PrintrBot Simple and I am having fun with it. There's certainly a lot to learn, and I'm still working out exactly what I need to do to get good reliable prints.

Any suggestions for software on an Ubuntu host? I'm currently using repetier-Host and slic3r, and have tried Cura. Anyone tried octoPi on a RPi?

The obvious next toy is a 3D scanner (or perhaps a filament extruder).

I found a couple of free apps for Android which claim to allow you to use your Android device as a 3D scanner.... "Exact 3D Extract" and Autodesk's "123D Catch".

Both of them work by you taking lots of photos of an object from different angles... the app also records location and orientation of your phone, and then software stitches it all together into a 3D model. In theory, at least.

But "Exact 3D Extract" says it is incompatible with my Galaxy S3. Has anyone tried this? Any idea what sort of hardware you need to run it?

I've made a couple of attempts with "123D Catch", without any success. It sends your images (between 20 and 70 of them) to a cloud server for processing, then returns the model to you. All of this is very slow, although I don't particularly care about that. My first attempt (30 photos) one did correctly grab bits of the background into a 3D model, but the object I was trying to model was a mess. The second attempt (70 photos) resulted in a "Failed to build model" response :( Anyone had any success with this?
