Model cooling
Print model on the build plate without glum. Only after cold down the printed objects
and build plate,remove the models easily.
Using scraper knife
After cooling, the printed object is still attached to the platform, and you can use a
scraper knife to remove the printed product. Keep the blade parallel to the printing
platform, slightly insert from the bottom of the model and remove the model with a
little force.

Put the printed objects into the water
Put the printed objects with PVA supports into the water and dissolve PVA supports.
There are some methods to speed up dissolve.
Using warm water to speed up dissolve PVA. If the main structure of printed objects is
PLA, it ensures the temperature of warm water should not over 35°C to avoid printed
objects shape deformation.
Stir water. The moving water can speed up solution of PVA.
Soak printed objects in the water about 10 mins, and remove supports by pincers. Then
put the printed objects into the water and dissolve remaining PVA easily.
Rinse with water
After the PVA support is completely dissolved, rinse the model with water to remove the
remaining PVA.
Removing PVA supports needs post-procession. Put the PVA supports model into the
water to dissolve supports.
Warm！Drop the platform down first before removing the model. Please pay attention
to the direction of shoveling to avoid scratches by using the scraper knife.
Do not damage the build plate when removing models.The scratch on the build plate
may cause print fails.

Dry model
Let the model dry completely and perform additional post-processing on the objects if
necessary.
Waste water treatment
Because PVA is biodegradable, it is easy to dispose of waste water afterwards. After
disposing of the waste water, flush it with hot water for 30 seconds to remove excess
PVA in the drain pipe and avoid blockage. Water can be used repeatedly to soak
multiple models, but may increase the dissolution time. Therefore it is recommended to
use fresh water to achieve the best effect.
