Hi there!

We're currently printing with PETG using a 3mm Dyze Pulsar extruder on a heated glass print bed. The adhesion is decent but could definitely be improved. I’m considering switching to a perforated aluminum heated print bed, thinking the holes might help secure the model in place.

I’d love to hear about your experiences with different print beds and what you’ve found to work best!

Thanks!

Hello Rens,

For PETG and PLA we find that a Garolite G10/FR4 sheet of about 6mm thickness works well above an aluminium heated bed.
We heat the bed to around 80°C for PLA and 100°C for PETG given that our bed is 1m² and without any enclosure plus the thickness of the sheet.
The part releases itself also well when the sheet has cooled down, no need to pry the print from the bed.

The perforated sheet can help to secure the model but I find that none of the materials stick well to aluminium unfortunately as we tried on the heated aluminium heated bed itself multiple times.

Flexible sheets coated with textured PEI also give good adhesion but are hard to source in large formats.

Otherwise blue painter tape or glue stick always helps for extra adhesion.
