I don’t know.  But I do know that in practice I’m not all that impressed with the performance of blue painter’s tape either.  It doesn’t have a very strong adhesion with the print bed (it’s adhesive was designed to be easily removable), so there are two cases in which I have had issues: 1.  Long […]

One of the most challenging things to do and maintain print quality with an extrusion style printer is to print a solid object (100% fill).

I have run tests on the X,Y and Z axis, brought the extruder well beyond 220C and have no doubts it will exceed expectation on printing. Printrboard- wired up and running (only […]
