My ultimate goal would be to produce a short run of models... I aim to print one, cast it and produce X number that I will paint and sell. Here's a pic of an idea I have: Before I go any further does the model need to be one continuous mesh? This guys head is a sphere and his hair is another modified sphere. I know my final output will be one mesh but it's made up of "islands" of objects. How do I know what size the model is. I remember reading this somewhere (I use Blender) and I know it's something to do with Blender units!?!? Will this print in one go or will I have to print the arms/hands separately and join them on later? This is also interesting as I may want to put something in his hand. Can I just add something and make sure it is touching the hand? Many thanks!
