Some neat features that could apply to our printers.

Let's start implementing them into the SD2's and 3's

printing ABS with zero warping
Rigid frame made of t-slot aluminium extrusion
Fully enclosed by acrylic and wood, doors on the front
A heated chamber capable of 65-70°C recirculating air temperature
Heated PCB print bed
Water cooled hot-ends and extruder steppers to ensure reliable extrusion in high ambient air temperature
Activated-carbon air filter to remove unpleasant smell of molten plastic
Semi-automatic print bed levelling makes calibrating the machine a matter of seconds
Z-leadscrew bearing supported on both ends, sugru spider coupling for absolutely wobble-free operation
Tool-free belt tensioning with built-in thumbwheels
Direct-drive extruders with high torque geared stepper motors
Permanent printbed material (FR4) – no Kapton or PET tape needed
Adjustable nozzle height to align both extruders on the same level
Custom designed, precision extruder drive gears to provide enough grip on the filament in a heated enviroment
Integrated LED lighting
