8.3 PVA solution for enhanced adhesion
Drop an approximate 10 cm long piece of PVA into half a liter of warm water and wait until it is com-
pletely dissolved. Apply an thin layer of this solution on the heating bed with a ne brush. When the lm
is dried it improves the adhesion between printed object and print bed.
Store the pre-made PVA solution in a sealed container so it can be used in the next print jobs. After the
application, the brush should be put into cold water so it is immediately ready for the next use.
8.5 PET-foil for printing bed coating
Please make sure that the device is without power supply while applying PET-foil to
the printing bed.
Also, please note that the right rear area of the printing bed must not get wet. The
bed´s power supply is located here.
The PET-lm functions as the printing bed´s coating and increases the adhesion between the printed
object and the heating bed´s surface. In the following we will describe the best way to apply the lm
without air bubbles.
• Apply a thin layer of water or glass cleaner (silicone free) on the bed´s surface
• While pulling o the carrier lm from the PET-lm, wet the adhesive side of the Pet-lm continuo-
usly.
• Place the damp side of the PET-lm onto the ceramic plate and align it with the plate
• Remove the excess uid with a squeegee. Work from the center outwards. Use a rag to absorb the
excess water.
Please make sure that there is no humidity at or under the heated bed before restarting the machine.
