			Can you explain a bit about infill on 3d parts please.  Is it something you put in the model, or something the printer settings control?  What does it look inside when its partially filled in?  Is it honeycomb or some other pattern?  How would the strength of say 25% infill compare to 100% infill? 
 
Thanks
