I am currently developing one of the most important parts of the 3d printer, the extruder. I have taken influences into the design from my experiences using a range of extruders designs from previous 3d printers. The extruder for this printer is a mk8 direct drive extruder with a bearing mechanism like the popular greg wades reloaded mechanism. This will allow ease of access, reloading and quick diagnoses. A major part of design that i will be working on, is ensuring that the nozzle tips are level. Perhaps some mechanism that allows easy adjustment of this will be developed. I will spend more time continuing to improve the design. The extruder will be 3d printed which will allow the design to be modified in the future if need be.
