3D printer heated bed high borosilicate glass

Reprap 3D printer heated bed with 3mm thick borosilicate glass. Size is 213 * 200 * 3mm

Suitable reprap machine heating circuit boards.

Benefits:

1 borosilicate materials, high transparency.

2 good adhesion when heated, plastic parts easily separated after cooling.

3 eliminates the trouble of replacing special plastic film, there is a special plastic film with the old problem of cohesive weakened.

1>,physical characteristics

Borosilicate glass has a very low thermal expansion coefficient, about one-third that of ordinary glass. This reduces material stresses caused by temperature gradients, thus making it more resistant to breaking. This makes it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. It is also used in the processing of high-level nuclear waste, where the waste is immobilised in the glass through a process known as vitrification (contrast with Synroc).

The special glass special used for 3D Printer:

l Great heat resistance performance,stable chemical property;

l High light transmission;

l Various thicknesses for you to choose;

l Wide optical application.
