After almost 2 years of development, the 444 is now a Beta platform.
This printer was created from parts printed on several of my smaller format (200 x 200) Proto-Plastik printers. The 444 was designed to be printed with smaller format 3D printers.
The Alpha unit performed quite well and I identified areas that needed focus. This resulted in a beefed up superstructure and much more focus on wire routing - yes, there are a LOT of wires!
As with all Proto-Plastik printers, version control will be via my Github site where you will find all STL/STEP files.
As this is still a work in progress, you will want to stay tuned for regular updates. My goal is to bring this and other Proto-Plastik printers to MRRF 2020.
