Hot Bed Enclosure V3

Issues of warping and cracking in ABS printing can be solved using a Heated Build Chamber. This kind of chamber is bulky and all the components of the printer (plastics, electronics) undergo a high temperature.

The principle of the proposed solution is to build a heated enclosure around the hot bed, and not as usual around the printer.

The expected advantages are:

+ Printer parts -electronic components,motors . . .- work at room temperarture,
+ No need of extra heating,
+ Less power to heat the bed (up to 50% less).

The enclosure consists of three main parts:

+ 2 insulation sheets that cover the entire hot bed,
+ 2 side plates attached to the printer frame,
+ and 2 Z shutters which follow the movement of the X axis.

Insulation sheets (upper covers) and shutters of the enclosure are fixed to a support consisting of aluminum angles and plastic parts, itself fixed to the X axis rods.Front and rear covers consist of 3 layers of mylar film, PE foam and aluminized pla
