Build platform: colorFabb’s nGen filament adheres best to heated build platforms. We recommend using BuildTak as your bed’s printing surface.

If printing on a glass bed, apply glue-stick. A very thin layer of glue will be sufficient to keep your print nicely in place. Another gluing method is dissolving PVA glue in water. The consistency of the mixture can be quite thin, like skim milk. By applying just a few drops and smearing the mixture out before you start printing will create a very thin layer which will hold the filament down.

Always allow the bed to cool before attempting to remove parts. We recommend using a BuildTak Flex Plate for easy rapid cooling.

*3D printers have a wide variety of hot-ends which makes it extremely difficult to provide a universal printing temperature. The provided temperature range should be considered a starting point to help you find a temperature that works for your print. Please refer back to your printer’s operating manual for safety and temperature specifics.
