Heated Build Enclosure Patent
Basics
Heated build chamber patent covers the case where the gantry is EXTERNAL to the build chamber.
This means that simple enclosures are ok.
The point of the patent is the mechanism for keeping the gantry outside of the hot zone - which is the only way to achieve temparatures higher than gantry components can tolerate.
Partial presence of gantry inside build chamber appears to be ok.
In the OSE case rods and belts could be inside, but motor could be outside. But this gets technical - what constitutes the gantry? How much of the gantry has to be EXTERNAL? Devil's in the details.
For now, simple thermal chambers are ok - and can keep valuable heat inside - but the heat can't be too high or it will break the gantry.
