MatterHackers LayerLock PEI Build Plate

SMOOTH SURFACE FOR PRECISE RESULTS

LayerLock Smooth PEI Plate delivers a flat, uniform surface that supports dimensionally consistent parts, especially in height-critical features. Select this surface for assemblies and close-fitting components where repeatable results and dependable fit matter most.

• Flat smooth surface allows for clean first-layer contact
• Achieve height consistency on dimension-critical features
• Ideal for tight-fit parts and precise assemblies

PRODUCE FINE-FINISH FIRST LAYERS

The matte PEI build surface of a LayerLock Smooth PEU Plate produces a sleek, uniform underside to prints. Achieve a polished first-layer finish that elevates the appearance of every print, from prototypes to display pieces, right off the bed.

• Uniform surface produces a smooth, clean first-layer
• Sleek underside finish enhances overall part appearance
• No cleanup required for the polished bottom surface

MORE TEXTURE FOR MORE ADHESION

LayerLock Textured PEI Plate combines a bold textured first-layer finish with reliable, high-grip adhesion. Its powder-coated surface strengthens the bond between the print and the bed while blending small first-layer variations into a uniform, tactile texture.

• Locks in first-layer adhesion for reliable print starts
• Creates a distinctive textured bottom finish on parts
• Boosts completion rates, saving time and filament

PART REMOVAL MADE QUICK AND SIMPLE

Spend more time printing and less time prying with LayerLock. Its removable magnetic spring-steel plate flexes to release parts. Prints often self-release as the PEI bed cools to ≤35°C, or pop free with a gentle bend for reliable long-term use.

• Prints often self-release as the bed cools to ≤35°C
• Magnetic removable plate for easy, tool-free removal
• PEI durably withstands temperature changes and repetitive flexing

INSTALLATION

• Align the LayerLock plate with the fixed points of your printer's platform.
• Lower the plate until it has securely attached to the magnetic platform.
• Calibrate Z-height and level your print bed before printing.
  • It is recommended to recalibrate whenever you switch plates, and every few prints on the same plate, since first-layer calibration can drift over time and between surfaces. Also, recalibrate if you make significant changes to print settings such as speed, layer height, or temperatures, because these can change flow and first-layer results.

That's it! You're ready to print. For a more detailed walkthrough on "How to Succeed" with a powder-coated PEI plate (installing, printing, maintenance, or troubleshooting), check out our article here!

MAINTENANCE

• Clean the surface with water and detergent when dust/grease naturally builds up.
  • IPA works too, but NOT acetone. This will damage the PEI.
• Accurate calibration is key to plate longevity.
  • Some materials like PETG, RYNO, and TPU may fuse to the PEI if printed too low. Accurate Z-height calibration and bed leveling avoid this.
• Minor flexing of the plate should suffice for removing prints.
  • Take precautions if resorting to a sharp scraper. This increases the risk of damaging the PEI.
  • Some materials will easily come off after the plate has cooled (ex. PLA, ABS), while others may peel off more easily while the plate is still hot (ex. PETG, TPU, TPE). Do NOT touch the plate while hot—use heat-resistant gloves.
