One of the challenges of 3D printing that I think – knock on wood – I’ve finally worked through is adherence to the print tray.

There’s nothing more frustrating than having a 3D print come loose from the tray while a print is underway, and it’s something that’s happened to me far more times than I even like to think about.

The Cerberus 3D Gigante’s large format prints are particularly prone to this problem – I have a few large prints the corners of which have “flipped up” slightly because they cooled faster than the rest of the print. See an example to the right – fortunately in this case, it works with the concept and theme of the sculpture!

Sometimes, though, a lifted corner ruins the print altogether.

Other times, on any of my printers, a 3D print simply comes loose from the print tray – then it’s game over.

But I’ve learned a few things and updated some to improve my quality and finish rate ….

My 3D Systems CubeX came with some sticky stuff that I used on that 3D printer until I got my Cerberus 3D machines, when I learned about using hairspray. Yes, hairspray. (I’m sure they wonder at the grocery store when I buy three or four cans of Suave Extreme Hold hairspray. I just smile.)

I still use hairspray – more on that in a moment – but I’ve gotten away from using blue tape. That was the other trick I learned when I got my Gigante. I’d apply painters’ blue tape – the kind that is supposed to release easily – to the print tray, pressing down just as hard as I could. It worked sometimes, but not always. Also, not all blue tape is created equally, apparently.

I don’t like the blue tape because

  1. It is hard to get off the tray
  2. It’s especially difficult to get off the sculptures
  3. It doesn’t always seem to work.

What seems to work best is a heated tray. That’s why I added one to my CubeX and another to the Gigante. 3D prints adhere much better with heat! I don’t think I’ve had a problem with large format prints lifting up since I installed the heated tray on the Gigante.

Of course, you don’t just use heat. Before I start a 3D print, I also clean the print tray well, then spray it liberally with hairspray before I start printing.

Of all the challenges with 3D printing, I think – THINK – I have this one licked.
