Problem: Tall parts falling over
Background: A customer who had a Fortus machine called complaining that tall parts were falling over during the build process, and he was losing materials and build time with incomplete parts.
The machine was functioning normally and builds that were not considered “tall” were working fine with no errors or obvious problems with the machine. Examination of the files in the Catalyst software showed no problems with layers missing or problems with a hidden gap.
Assessment: support was insufficient to secure the part to the build tray
Fix: Support team recommended a Z, and XY calibration before printing again. Also suggested that since the part was tall and without a base large enough to secure it to the build tray, that “surround” as his support option would be a better choice.
In general when a part is over 4” in height with a build base that is less than 25% of the height, using a “surround” support style will give a better assurance of completed builds.
Conclusions – The print failure was due to the part being tall and not enough support of the build structure for the height.
