Hot Bed Enclosure V3

Issues of warping and cracking in ABS printing can be easily resolved using a Heated Build Chamber. This type of chamber is quite bulky, and all printer components (plastics, electronics) undergo high temperatures. The proposed solution involves building a heated enclosure around the hot bed instead of the entire printer. This approach offers several benefits. Printer parts, including electronic components and motors, operate at room temperature with this setup, eliminating the need for extra heating. Additionally, power consumption is significantly reduced - up to 50% less than usual - as less energy is required to heat the bed. The enclosure consists of three main components: two insulation sheets covering the entire hot bed, two side plates attached to the printer frame, and two Z shutters that follow the movement of the X axis. Insulation sheets (upper covers) and shutters are fixed to a support made from aluminum angles and plastic parts, which is itself attached to the X axis rods. Front and rear covers consist of three layers: mylar film, PE foam, and aluminized plastic film.

The X shutters from the previous designs have been eliminated, and the distance between the angles has been reduced to minimize heat loss.
