OP here again with an edit:It needs to be finished approximately until 7th January
>>545759get blender (free) and make human (free). Make a human and import it into blender as a base. Then you can sculpt your head the way you want (or not at all) and delete unnecessary faces of the rest of the body. Ask your friends what kind of file format their printer takes and export from blender.
>>545761Thx for the quick answer. I will get Blender and try my best
>>545759if is ur first time get something like facegen of something like that, is not for riggin so the topology doesn't matterhttps://www.youtube.com/watch?v=kvVj7p53zCEu can't do it in Blender without lot of practice
>>545759The model is only as good as you can sculpt it. Depending on what printer you have and the quality of it. It might come out terrible looking with a bunch of extra strings of plastic. It's hard to explain. But when you first print it off it will be messy
>>545759or download DAZ studio for free, export one of their very detailed models as an .obj and ur done
