CROSSBOW3
Normally, a printer can replicate itself, I tried to make a printer that would produce itself!
I mixed structure and mechanics
Its strenghts are ease of assembly and maintenance, starting from basic components you can put all together in 3 hours and in some minutes you can enter and replace ever part
the essential structure is therefore solid and movements are driven by linear actuators of 80 mm
its movements can reach 300 mm/second and for me it works best from 60 to 80 mm following pla/pet, wood, bronze

extruder (0.40 hole with filament of 1.75) is totally nude and allows not only to check any problems but also to rectify during printing
plate 40x30(Z20) does not require regulation, it allows remote preparation and cleaning,
I made some printing trials, of various size and duration, among the most interesting the one s where I printed all stress texts and “Robotica” at life-size http://www.thingiverse.com/thing:614366
in the last two weeks I printed 300 hours non-stop (I paused 2/3 minutes just to change filament and coil) with printings of about 5, 15, 40 and 60 hours ...
I published along with pictures and videos also stl files for plastic parts
this printer whose commercial name will be Qubit is part of a project leading to printing center service promoted by Fly-Image Technologies sagl in the next months
but in agreement with partners the printer is free for non commercial use
to publish here all the data about the project would require a great deal, then I apologize if I do not publish a technical project (that I am not able to do) and a complete list of components (yet to be finalized) but I am at your disposal at this address
if any of you want to make one of this printer, you can write to me and I can explain all I know and is needed
