recommended bed material, gluestick for nylon

I'm having trouble getting MatterHackers nylon to adhere to the bed; it curls loose after a few layers.  I'm using a 0.6mm nozzle at 265C with the textured PEI sheet at 100C.  I've seen recommendations elsewhere to use a garolite sheet and glue; is that recommended?  What are people using to get nylon to stick?

Best Answer by Artur5:

A garolite board glued to a steel plate should be OK, provided you use a very thin board, ideally 1 mm or less thick. Otherwise the Pinda sensor would be too far away from the steel underneath the garolite and the readings wouldn’t be accurate.

I tried this setup time ago and it worked OK, but not perfect. Warping is still a problem with some nylon brands. To avoid the issue you need to apply a strong adhesive. Forget about glue stick, too messy and it won’t be of much use with nylon. There’re better options like Dimafix or Magigoo PA.  

Another possibility, in my opinion better than the garolite board, is to purchase the Prusa powder coated PA steel sheet, specially designed for printing nylon filaments. I use it in combination with Prusament PA-CF11 and it works like a charm. Glue isn’t needed at all. In fact, Prusa forbids to use any kind of adhesive on it.

Be aware that the PA steel plate is only for nylon filaments. An excellent solution if you print this stuff often but, if not, you should consider whether the investment it’s worthwhile.

I second the Prusa PA sheet.

Thanks, I didn't realize there was a special PA sheet.  Unfortunately, they're out of stock at the moment.

I managed to get my prints done by adding a wide (10mm) outside brim with 0.0 clearance to the part.  That appeared to give the first layer a more evenly spread adhesion base and prevented the part curling.  The part itself is about 30mm x 50mm.

In the meantime, until the Prusa PA sheet is available, you could try Magigoo PA:

Thanks.  Do you use that with the smooth PEI sheet or the textured one?  Or some other sheet?

How many prints do you get out of one 50ml bottle?  I know it depends on first layer size, but a rough guess based on some "average" area, say 1600mm2?

(nice tag line, btw)

I use Magigoo with the textured sheet. If you use magigoo correctly, one glue stick is enough for 100 or more prints. It's expensive but a good alternative.
