Eight-station tool changer fitted inside an enclosed Core One+

When this machine is running, it works through a cylindrical print while an external screen at the front shows a colorful segmented preview of the part, with a progress marker reading 23%. Through the front door the print area stays visible while the tools sit docked, and the active head pops over to the waste area, squeezes out a small filament bead, wipes the nozzle and gets straight back to the job. That cycle looks smooth and quick.



The base machine is an enclosed Prusa Core One+ that 3D Musketeers has fitted with an INDX tool changer offering eight stations, and the rack carries positions numbered 1 through 8. The print head is a grey Nextruder-style unit, and behind it sits a linear rail assembly carrying printed warning icons inside triangles. Two PTFE tubes run vertically through the foreground of the build, which gives the gantry area a tidy, deliberate look.



The detail that stands out to me is the waste handling. Rather than a prime tower, the purge bucket deposits small purge pellets, and a long, narrow internal tray collects the extruded scraps during printing. That tray already holds numerous little discarded purges, mostly black with some green flecks, so the system clearly produces very little material per swap. The print bed also shows partially visible text reading PRUSA next to alignment markings.



One thing remains open. A fair question is whether the purge bucket is optional or whether a wipe tower can still be chosen, and 3D Musketeers has not answered that yet. General availability of the system also has not been confirmed, so anyone keen on copying this will have to wait for word on that front.

Curious how the discarded plastic is dealt with once the head has purged and wiped. Does everything land in that long tray inside the enclosure, or is something else catching it during a longer run?

I think dropping tiny pellets instead of building a prime tower is a smart call. It keeps the whole bed free for the actual part instead of sacrificing a column to purging. The trade-off is capacity, since a small bucket filling up mid-print with hundreds of tool changes would be the obvious risk.

A simple modification worth trying would be an opening in the side of the tray, angled so the little purges slide out into a larger container sitting outside the machine. That would take the capacity worry off the table without touching anything inside the enclosure.

The long, narrow tray inside collects the extruded scraps while printing, and the purge bucket puts down small pellets rather than using a prime tower. As for capacity, the maker has said the purge amount is really tiny and that the bucket can last multiple prints, with waste pictures and raw numbers promised.
