Square glass build plate 310 by 310 mm four mm thick rounded corners lattice texture

LONGER

LONGER LK5 PRO / LK1 310×310 mm 4 mm glass build plate

SKU CH-AGCR-RCS66

A 310×310 mm, 4 mm glass build plate with a microporous composite coating that expands when heated for strong adhesion and shrinks on cooling for easy print removal.

  • No edge curling thanks to microporous coating that expands when heated
  • Easy print removal as coating shrinks on cooling, saving at least 40% removal time
  • Superior flatness below .2 mm for smoother first layers than magnetic or PEI beds
  • Very durable inorganic coating with 8 Mohs hardness withstands 400ºC operating temperature
  • Rounded R5 mm corners on 310×310 mm, 4 mm glass plate fit LK5 Pro and LK1 printers

310×310 mm glass build plate

The LONGER LK5 PRO / LK1 build plate is a 4 mm thick glass sheet sized 310×310 mm for compatible Longer printers. Rounded R5 mm corners and a microporous composite coating give a flat surface rated below .2 mm flatness. It replaces magnetic or PEI sheets for users who want a rigid, dimensionally stable bed. Builders needing a different bed size or a flexible removal surface cannot use this plate.

Microporous coating behaviour

The coating expands its micro-pores as the bed heats, increasing adhesion so first layers stick without edge curling. When the bed cools the pores shrink, letting small prints release by hand and large prints come off with basic tools, cutting removal time by at least 40 %. No glue stick, hairspray or extra surface preparation is required for typical filaments.

400 °C thermal limit

The inorganic coating reaches 8 Mohs hardness and is rated for continuous operation at 400 °C, well above common printing temperatures. The glass substrate itself defines the practical ceiling; exceeding the printer’s own bed-heater capability or using adhesives not rated for this temperature can damage the surface. No magnetic base or flexible steel sheet is included, so the plate must be clamped or bonded to the existing heater.

Questions about this item

How long will the microporous composite coating on the 310×310 mm glass plate last before it needs replacement?

The inorganic coating has a hardness of 8 Mohs and is rated to withstand 400 ºC, so it should endure many heating cycles without degrading.

What limits continuous printing on this build plate first — adhesion loss or thermal stress?

Flatness is held below .2 mm across the surface, and the coating expands with heat to increase grip, so thermal stress on the glass is the practical limit.

How much noise, heat or extra power does the 4 mm glass plate add when the printer runs all day?

The plate itself adds no noise or power draw; it simply stores heat evenly, and the microporous coating releases prints once the bed cools.
