Unlike injection molded objects, 3D printed objects are built using layers. These layers can DELAMINATE if stress is applied in parallel to the layers. Parts should be printed perpendicular to the stress that will be applied to them.

Printing the rod laying down will create LAYERS that will make it difficult to "snap" in half.
WEAK PRINT ORIENTATION
WEAK PRINT ORIENTATION
Printing in this orientation will make the rod prone to SNAPPING in half!

This print orientation is the WORST! The legs of this table will be VERY fragile and likely to break. In addition there is lots of unnecessary support material that will take extra time to print and then remove post printing.

The legs on this object will still be fragile and prone to breaking BUT this has the optimal print orientation because there will be no supports required for this print.

This print orientation is the goldilocks of print orientation. The legs on this table will have the highest strength and will require the least amount of support material.

Note. Remember Print Settings
Note. Remember Print Settings
The following settings must be adjusted for each print!
gCode File Name (use your name + the date)
