Question 1

3D Printing Quality

If any of the following are present, throw the part out and print a new one: ·         Print has substantial warping.  ·         Print layers are separating and will impact function or strength.    ·         Print has unacceptable aesthetic irregularities.

Question 2

Accepted Answer

Check to ensure that the brim and supports are removed.  If they are not, remove them with pliers or a deburring tool and file to smooth.

Question 3
