Helical Sprues in 3D Printed Sand Moulds

The helical path uses friction and centrifugal force to slow the metal down, ensuring it enters the mold below the critical 0.5 m/s threshold.

Reduced Inclusions
By preventing "splashing" at the base of the sprue, it can reduce globular oxide inclusions by up to 35% compared to straight sprues.

Received my Creality CR-10 S4 3D printer last week and am anxious to learn this machine, my first. Meanwhile, I'm looking for recommended CAD programs for making patterns in PLA. These would be great projects to keep me busy over the winter.
