If you have problems getting a 3D print to stick to the bed, you might consider using glue to — hopefully temporarily — attach the print to the bed. In addition, some plastics glue together well if you use a solvent. [Stefan] asks the question: What if you use solvent to glue each layer of a 3D print to the previous layer? The answer is in the video below.
If you know [Stefan], he is always meticulous, so the first test was with normal ABS parts. Then he used a solvent to glue two broken parts together to show how a single layer does with bonding. Then he moved toward trying the solvent for each layer.
