Print Surfaces for 3D Printers


Also known as build sheets, stick these sheets to your printer bed for more accurate 3D printed parts than those made on bare printer beds, masking tape, and glue. They won’t transfer heat between your part and printer bed, which means they grip your part as it prints to keep it from shifting. Then they easily release the part without damaging it once it’s cooled. Because they’re insulating, they also protect glass printer beds from cracking due to sudden temperature changes, so you won’t need to replace the bed as often. You can reuse these sheets multiple times, since they’re durable and stand up to heat.
Use these sheets with fused filament fabrication (FFF) 3D printers. Cut them to size with scissors before sticking them to your printer bed. For large print surfaces, use primer and smoothing tools (both sold separately) to remove wrinkles and trapped air bubbles.
PEI print surfaces don’t grip as tightly as plastic-blend print surfaces, making them easier for removing sticky filaments, such as PETG. They also last longer. Their smooth exterior leaves a smooth finish on the bottom of your part.
