I often have trouble with prints being especially difficult to remove from the build plate on my Micro3D printer. My wife suggested using a hair dryer on the underside of the plate. I was initially appalled at the idea, but now I think she may be on to something. Is this safe? Good idea? Bad idea? Heresay?
It's what i do. Painters tape. are you using the m3d plastic? that's why. the coating is to make sure it sticks their only plan to get it off is to bend the plate a little bit. Hair drier won't end the world. don't hold the plate and hair dry it, that might hurt. But M3D sells spare plates it you destroy it. Try it out, tell us what happens.
I agree to Tom's first part of the answer, usually you'd cool down the plate to loosen the print. This is reasoned by the shrinkage of the builplate while the print stays extended. The strain put into the interface helps to get the print of. Warming the plate could essentially do the same, but since you deposit a warm filament, one would assume that by warming up you will reduce the strain that has been built up by the regular cooling of the filament already.
I guess an uneven heating with a hairdryer will probably introduce uneven strain or evan some kind of warping of the buildplate that puts more strain to the interface which makes your approach work. If you want to test whether you have some local deformation you could characterize this by reflecting a laserpointer from the heatbed and marking the reflection on a rather far away wall for some controlled positions you can get the laser in (by say putting it on a photography tripod). The change of this reflections towards each other could tell you about the deformation.
I also agree that most of the hairdryers around would not be hot enough to be a worry, but since most of the Micro3D is made from plastic I would put twice the time into figuring out if that is really true.
Just for the fun of it, you could put an ice cube next to your finished print if you make sure that molten water will not go anywhere it is not supposed to be. Maybe this lifts off the print as well. However, I do not recommend doing this, of course.
That was a problem for me too. My M3d printer was getting stuck to the plate. However, I now print on painters tape, and I put down painters take on the bed. Then I glue stick the tape, and when I am done, I just pull it up.
You should try it, because it will allow you to print with other then the m3d plastic.
