4.5 Remove support material
Dissolve PVA support
PVA support structures can be removed by dissolving the PVA in water. This takes several hours and leaves no trace
afterwards. Follow the steps below and refer to the Ultimaker website for additional tips and information.
1. Submerge the print in water to let the PVA dissolve
2. Rinse the print with clean water to remove any excess PVA
3. Let the print dry completely
4. Dispose of the waste water
PVA is a biodegradable material, and in most cases disposing the water afterwards is easy. However, it is
recommended that you check local regulations for more comprehensive guidance. The water can be disposed
of down the drain, providing the waste water distribution network is connected to a wastewater treatment
plant. After disposal, run hot water from the tap for approximately 30 seconds to remove any excess saturated
PVA water and to avoid longer-term clogging issues.
It is possible to use the water for more than one print, however, this might extend the dissolving time.
Through repeated use, water becomes saturated by previously dissolved PVA. For the quickest result, fresh
water is recommended.
Remove Breakaway support
Prints using Ultimaker Breakaway as support material will require post-processing to remove the support
structures. This can be achieved by breaking the support structures from the build material. Follow the steps below
and refer to the Ultimaker website for additional tips and information.
It is advised to wear protective gloves when the support structure contains sharp corners or when
working with larger models.
1. Tear away the majority of the inner support structure using pliers
2. Use cutting pliers to grip the Breakaway support interface and pull it away from the model
3. Remove the last traces of the Breakaway support using cutting pliers or tweezers
