What Causes Warping (Edge Lifting) and How to Prevent It?

Warping is when the corners of a print lift off the build plate and curl upward — it is the most common cause of failure in large parts. The reason is physical: plastic shrinks as it cools, and the upper layers pull the lower layers, peeling the part away from the bed.

Solutions: set the bed temperature to suit the material (100°C+ for ABS), keep the bed surface clean and use an adhesive (glue stick, PEI), eliminate airflow — a fully enclosed enclosure is essential for ABS — and turn off the cooling fan for the first layers; add a brim or raft to the model.

On the design side: rounding sharp corners and increasing the contact area with the bed significantly reduces the risk of warping. We print your large ABS parts safely in our enclosed-chamber machines.
