I understand the principle of why a heater block is used. Helping to reduce temperature variation as the filament is extruded using the heat capacity of the block.
But I’m wondering why it takes the form it does? I imagine it is cuboid in shape just for convenience as it’s easy to machine?
From a surface area to volume ratio a cuboid appears to be one of the worst shapes to use.
Note: I am currently doing a project which requires me to increase the tool clearance of the nozzle of a 3D printer. Hence why I am exploring alternative print head configurations and heater block design trying to minimise the profile of the print head as much as possible.
