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.
1. Submerge the print in water. By placing a print with PVA in water, the PVA will slowly dissolve. This process can
be sped up by using:
• Warm water. Warm water will decrease the dissolving time. When using PLA for the build material, ensure that
the water is no hotter than 35 °C, otherwise the PLA part may deform. Never use water above 50 °C, as this
increases risk of burning
• Stirring. Use stirred/running water to decrease the dissolving time. Moving water enables the PVA to dissolve
more quickly (in some cases under three hours, depending on the amount of support material used)
• Pliers. You can also speed up PVA dissolution by placing the print in water for approximately 10 minutes, then
removing most of the support with pliers. When the print is placed back in the water, only the remaining parts
of PVA will need to be dissolved
2. Rinse with water. After PVA supports are totally dissolved, rinse the print with water to remove any excess PVA
3. Let the print dry completely and apply additional post-processing to the build material if desired
4. Disposal of waste water. PVA is a biodegradable material, and in most cases disposing of used 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 your 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, the 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.
It is advised to wear protective gloves when the support structure contains sharp corners or when
working with bigger models.
1. Tear the inner support structure. Start by removing the walls of the support structure with a gripping plier.
This allows you to quickly tear away the majority of the inner support structure
2. Pull the Breakaway support from the build material. After removing most of the support structure, the
remaining part(s) can be pulled from the build material. Use cutting pliers to grip the Breakaway support
in a corner and try to carefully get underneath it, then bend it upwards. Repeat this for several corners,
so that you can loosen the support from the model around the corners. After this, pull the Breakaway
support from the model
3. Peel the last traces from the model. Sometimes a final layer of the support material remains after pulling the
Breakaway support from the build material. If this happens, use cutting pliers to peel it off from a loose edge.
Any leftover traces on the model can be removed with tweezers
