Heated bed not required, if available set it between 20-60 °C. SoLay can be promoted by Bowden. SoLay stick on most roughened surfaces such as Kapton tape or blue tape.

A nozzle with an opening of 0.4 mm is well suited. 0.2 mm is a good layer thickness, the thicker the layer is, the rougher the object.

Solay is best stored dry. If the material have absorbed moisture after some time, for better result, we recommend to dry the filament in an oven at about 80 °C for four to five hours.

How to dye the filament
• Dye the filament in a glass with ink for permanent markers, add alcohol in the quantity of 1:1 or more to brighten up the color.
• Paint it on with a brush. Add also alcohol to the ink.
• Paint onto the printed object with a permanent marker. You can buy these kind of markers in a graffiti shop.

Running shoes, experimental shoes, why not for belts or other wearables. Also absorbing cushions, inner soles, straps.
