I-Beam

This is an i-beam I made on Autodesk Inventor. There is a 90° difference(not necessary twist) between the bottom sketch and top sketch of the part. I used the loft feature to generate this surface. No supports. You can choose a resolution but note that lower layer height yields better results. I recommend you print vertically.

This peice has a pardox feel to it but it's very strong and light(when printed/manufactured properly). I hope this i-beam can be used in real world applications.
