Adamczak, Bochnia and Laczmarska [42] looked into the variance of
parts printed on an Objet350 Connex and showed that under very specific conditions little variance is found. The Objet350 Connex can print
up to three discrete materials at a time and was also studied by Barclift
and Williams [6]. Focusing on in-process parameters, they examined
the influence of the parts' longitudinal alignment on the printing table
along the X and Y directions,1 the transverse alignment in X, Y and Z
direction and the part spacing for VeroWhite (FullCure 830) material.
A significant impact was found only for the latter one, where a tightspacing yielded a higher UV exposure time per part and thus a stronger
mechanical strength. They also pointed out the complexity and interrelation of impacting factors and demonstrated the need for a systematic
approach.
