Description

For those of you who remember it, this is the Sega Genesis that came out in 1989. 16 Bit awesome is what it was when it came out. If you print one, please let me see it. The vent panel isn't complete, it is damaged, I might fix it in the future, but I don't really feel like it at the moment. The model is water tight so it should be able to be printed.

Well, I've made a 50% version of this, and I made a timelapse video of it. Enjoy. And thanks for posting this! facebook.com/video/video.php?v=10201035632239517&;saved
I was able to open the .obj file in max and add an optimize modifier to reduce the polygons, then the file was small enough to load into makerware and I was able to save it out to a binary .STL file, I will upload the .stl version of this. I hope topology isn't a factor in 3d printing, because the mesh looks like crap in wireframe view with the polycount lowered.
I tried exporting to STL from studio max and it crashed. I am able to import OBJ files into makerware and then save them as .stl files, but makerware only loads some of the files I have. This particular scanned image won't load in makerware. How can we identify why one obj file will open and another will not? I think there are too many polygons on these scans and it's crashing high end systems. I might have to bring the scans into a program like topogun to make yet another model by wrapping around the scanned mesh as a refrence, that should produce a lower polygon model, then maybe these scans can actually be used. I'm finding that the scans take so much data, You can't really do anything with the models once they're scanned.

Tell me how it works out, my printer hasn't arrived yet.

Edit: If you have access to a program called Topogun, you could use it to create a much lower poly version of this model. It can use a refrence mesh (This sega genesis .obj file) and you can wrap another mesh around it like shrinkwrap. The resulting mesh is much lower in poly count, it allows you to create all the proper edge loops etc. We don't have it yet, but we got the scanner for use with 3d animation and we need to use that program to re do the topology of the meshes we are going to animate so they are manageable in 3dsmax

I have 3dsmax, It has an option to export to STL, I'll look into it, I think it asks if I want to do Binary or ASCII, I don't know which one to select. I'll also check out netfabb so I can see if I can fix these things before putting them up. I'll end up redoing this one with lower res, it will still look just as good, but it'll have a lot less polygons.
Thanks! Binary STL is fine. If we had it at lower res, that would help a lot.

I'd love to try to print this for you, but I'm having considerable trouble getting a clean copy of it. Netfabb on my underpowered computer is choking on the would-be repair. If you can find your way to making an STL of this, maybe Netfabb cloud services could be of help.
I used a Nextengine 3d Scanner HD. When I bought this thing, I thought I was going to be able to use it just like a photocopier. What I got was an 8 lb box shaped like an Xbox on its side that has to be used with a tri-pod, crazy angling and it all has to be done at a focal point of 6.5 inches away from the face of this thing. Then you have to stictch it all together after each scan. 2 days later I have a much better idea of how to actually use the scanner and the realization that this is NOTHING AT ALL like going to Kinko's and putting paper in a machine, pushing copy and walking away. I'll probably do another one later, I learned half way through this one that I could have used a lower setting to gather the data. I had to spray the genesis with SKD 2 in order to insure the laser didn't lose data because of the reflective surface and this scanner picked up all the imperfections, that's why it has a painted look to it. I really want to scan a Han Solo Frozen in Carbonite that we made in clay that was actually used as the gift wrapping for an Ipod Mini, so I tried this first since it is "box shapped". I think it is going to be hard to get Han Solo scanned.
I'm going to print this right away! I might even be inspired to clean it up in a CAD program. What did you use to scan it?
thats gonna take a lot of plastic, if i get some time i'll have a look at it
I don't know how the model translates into the amount of plastic used, my printer isn't here yet... I have played with the makerware program though, It looks like you can scale the item to make it much smaller to reduce the amnt of plastic used? If anyone prints this, PLEASE link it so I can see what it looks like when it comes out.
