This reduces the stress caused by contraction which, in turn, helps to reduce warping. This causes a printed object to cool much more slowly. Today, most people are printing on a heated print bed. This caused high levels of lateral stress and ABS curling was commonplace. Because of this, printed objects tended to cool very quickly once a job was underway.

Once upon a time, heated print beds were relatively rare. The Best Ways to Prevent 3D Print Warping and Curling Heated Bed You’ll need to heat it up evenly all over. Don’t bother just putting the print back on a heated bed, or worse heating the pan – because this will just heat the bottom of the print. Repeat this process until it works sufficiently. You’ll need to hold it for a few minutes until it’s cooled a bit. Heat it up on full power, and move the dryer around to evenly heat it.Īfter a minute or so, you can turn off the dryer and you should be able to hold the print down to bend it back to a flat shape. Get a hairdryer and place the print in the pan. You’ll need a large metal surface, like a frying pan, big enough to place the print bed side down (just the way up it came off your print bed). To do this, you’ll need to heat up the print close to its glass transition temperature (where it’ll get just soft enough to mold back down). While not all warped prints can be fixed, if the print bottom warping is slight – and your print isn’t too thick or large in volume you might just be able to salvage it. Luckily there are simple ways to do all three, which we’ll cover shortly.īut first, what if it’s too late – and you have a warped print right now? Well, maybe not all is lost just yet… How To Fix a Warped Print There are really only three ways to prevent 3D printer curling increasing ambient temperature to reduce cooling time, or seriously improving your bed adhesion.

The result is not pleasing to the eye and usually makes the object unusable. There, the pulling stress exerted on both sides causes the corner of the object to deform and pull up and inward. This stress is greatest at corners where two sides meet. The quicker the cooling occurs, the greater the stress on the object.
