Heated Bed Borosilicate Glass Plate Size 213*200*3mm Tempered Glass Plate Only for 3D Printer

1, size

This is a very obvious parameter. The glass plate needs to fit snugly against the platform to avoid vibration during printing. If it is too large or too small, the bottom plate clamp will not be used.

The other is the optimum thickness. The 3-4 mm glass hot bed is a standard thickness that is sufficient to maintain strength and heat dissipation. If you choose a very thin glass plate (for example, 1mm), it is easy to crack due to high temperature or accidental contact with the hot end. The thickness should be selected for the size of the test bed. For large hot beds, a thickness of 6 mm may need to be considered.

2, thermal shock resistance

High-performance glass does not break when the temperature changes rapidly. This durability is called thermal shock resistance. When choosing the temperature of the 3D printer nozzle, choose a suitable glass hot bed.


3, heat resistance

Even with tempered glass, repeated heating and cooling can cause it to lose strength. However, there are still a lot of special glass on the market, which can be considered if it is often used at extreme limits. For example, ceramic glass can be used at extremely high temperatures, with consistent strength and without the effects of heating and cooling cycles. Another commonly used glass plate is borosilicate glass, which consists of boron trioxide and silicon dioxide, which is resistant to thermal expansion and thermal shock, and exhibits little physical change at high temperatures, with significant thermal properties and Almost indestructible, it is ideal for use as a hot bed for 3D printers.
