What's your bed set up?

Has anyone been able to print on the aluminum without any tape, glue....? I've tried a few ways and find a painters tape bed sprayed with 3m adhesive is the best for me. Diluted wood glue works as well. The only tape I have is Scotch Blue (the good stuff I used for painting) and find that if I scuff it with steel wool it works better. I haven't tried the cheap stuff yet. I am in the process of installing the heated bed but it didn't make any difference in pla sticking to the aluminum. At the moment the heater is there and running off of a separate power supply but it's not plastered to the original. It's running about 55C. (Different issue there as well).

So the question is "What do you use?" for your prints as a print bed? I've read that glass works well and could have a piece cut but figured I'd ask.

Answer this question I have this problem too

Is this a good question?

Hello Walt,

I use stick glue from my child. It work well. To print on the alumium plate your noze need to be very close to it. I try at 0.2 with the first layer at 0.35.

In this case the PLA is well apply to the plate. The problem is that you need to redice the pressure into the head sometime.


Heated or non heated bed?

Hello Walt,

I use very cheap painters tape with glue stick. My bed is unheated and leveled.

I never print directly to the aluminum itself, but did scuff the bed when I first got the unit by crashing the head in to it. (Ouch)

I have started to epoxy textured ABS sheets down to a piece of glass (for ABS printing) and use binder clips to hold it to the bed. It works remarkably well, I just set the nozzle a tiny bit closer to the sheet than I would the tape, to adjust for the texture (while changing my nozzle height, as the thickness of the new plate must be accounted for when setting the nozzle). I do the same for PLA, but I still have a very hard time finding a reliable source for thin PLA sheets. I purchased some scraps from a local company a while back. It can be used with a heated bed, or without one, both work extremely well and they can be reused many times over.
