My Think3DPrint3D (T3P3) Kossel Mini is currently using the geared extruder in a bowden configuration that T3P3 supplied as part of the kit – an extruder that has served me well so far (and one that I’ll be keeping intact as a backup for future use should I decide to go for the dual-nozzle setup in the future)
If you’re not familiar with Titan, it’s a conventionally manufactured extruder drive using a NEMA 17 motor. As uses specific precision engineered drives instead of the usual “hobbed bolt” common on RepRap designs.
Using a manufactured extruder drive might not be true to the ethos of the reprap philosophy – open source, and 3D printable wherever possible – and there are already great printed extruder designs out there – but I want a printer that is low maintenance, and when maintenance is needed, is easy to maintain – the T3P3 extruder, whilst compact and powerful, has some disadvantages – there’s no easy access to the hobbed bolt that drives the filament for cleaning, and doesn’t have any kind of spring tension adjuster – all things that the Titan has.
Although the image above from E3D shows the Titan in it’s direct drive configuration – I’ll be using it in a bowden setup (as is common for Delta designs) to reduce the moving weight of the effector of my printer.
I plan a series of posts to cover the installation and calibration of this new extruder, along with any problems I encounter along the way.
