Step 1: Software Needed
If you are a student (like me) you can use 3DS max for free (link)
If you aren't a student blender is a good option for free 3D modeling (my Instructable doesn't use this however)
The only other thing you need is about $20 and a shapeways account (or other site)
Step 2: Taking Pictures
Step 3: Generate 3D Model
Step 4: Export / Import
Step 5: Clean Up
start by deleting all the stuff that is around the model of yourself, then proceed to clean up the area around you're feet (if you were standing on the ground). Deleting the unwanted portions of the model is easy (click, press delete) so I won't say any more about it.
now some things to make selecting the single polygones a little easier go to preferences then viewports then change the scroll distance to .15mm or something else small (for cleaning up the area around the feet)
Step 6: Closing the Holes
Doing so is relativity easy:
first change the model into an editable poly (right click select convert to --> editable poly) probably did this in the last step but if not do so
Next select edge mode from the properties plane
select all the edges that surround the hole(s)
select cap holes from the modifiers list.
follow the pics if that didn't make sense.
EDIT rather than selecting each of the edges along the holes convert the object into a mesh then select the whole thing and apply the cap holes modifier.
Step 7: The Mutations
To add extra limbs requires you to make a copy of the model you have delete the parts you don't want extras of and then reattach the extra limb.
when reattaching the extra limb make sure that it is completely submerged in the model, meaning that there is no gap between the new limb and the existing model keeping it "water tight".
Then when the new limb is in the right place select both parts and group them ctrl g or group from the menu at the top.
Edit you may also want to add a small base to the objects so that when they are printed they will be able to stand up by themselves (look at the main picture)
Step 8: Scaling
Next create a box and then change it's height to the height you want you're mutated model to be. You can do this by changing the height of the box in the properties panel. Then scale you're model to the right size be sure to scale evenly by selecting all 3 axis click in the center of the scale gizmo so that it all turns yellow .
Then delete the box
Step 9: Ordering the Print
Uploading a model to shapeways was not difficult all that was required was an account. I couldn't get a full color model to be accepted successfully, so I guess I'll just have to paint it when it shows up.
First export it from max as an .stl
then go to shape ways and select upload model
when model is accepted place an order
wait 10+ days model should show up (still waiting for mine)
If you are having trouble uploading it to shapeways check the size again and then repair it using netfabb studio (there is a free version). Here is one way to use it.
