Gizmo Dorks PEI Sheet 3D Printer Build Surface 300mm x 300mm (11.8" x 11.8") with Laminated 3M 468MP Adhesive, Made in The USA

Installation

The Polyetherimide sheet comes with 3M 468MP adhesive already laminated to the PEI. Apply the PEI with pressure and at an angle to prevent and minimize air bubbles. Once applied set the print bed to 60C and apply pressure evenly across the PEI in a sweeping fashion to firmly set the adhesive. Please use a towel to avoid getting burned. Level the bed and set the height of the nozzle before printing.

If PEI is installed to the top surface of a bed sandwich (a build plate with multiple layers), it is recommended to install PEI on top of borosilicate glass.

Use

Heat the bed to the desired temperatures for printing (60 C for PLA and 100 C for ABS). Depending on how thick your bed sandwich is, your set temperature may not be your surface PEI temperature.

When the print is completed, let the bed cool, and the part will be easy to release from the PEI surface. Parts are actually easier to remove if released before the bed becomes completely cold.

Leveling the bed is very, very important when using PEI. You want the first layer to be close enough to be squished a little. PETG is an exception and doesn't like squished layers, in which case a Z gap should be used.

Maintenance

Clean in between prints with isopropyl alcohol. Acetone can be used instead of isopropyl alcohol, but must be used on a cold bed. Light sanding with 600 grit sand paper can be done after lots of printing to give the PEI sheet more life.
