Sanding

• will need different seams

• after sanding, spray filler and spray paint can make the parts to look not like 3D printed

• able adjust how smooth we want the surface to be

• can be accurate in a way since we are sanding the parts that we want

• could make a mistake of sanding to much

• if it is a large part, time consuming to sand the whole part

  • which gives toxic chemical when heated

  • shrinks when it is cold

    • not suitable

• when doing this, could be dangerous since it is flammable
