That's great stuff.

I've always wondered about variation in 'dot' and 'line' resolutions on extrusion-based set-ups, particularly relating to head movement (speed) & environmental conditions.

I've only had experience running (and servicing) an Objet Connex system that uses printing heads & UV curable resin. It used a stainless steel bar w/ a separate motor & cleaning system to 'flatten' each layer w/ each pass of the print head. I've always wondered if there were any FDA equivalents... I guess there is always the option to intentionally 'smear'.

The DIY 3D printing world is totally a trial-and-error art in my mind, as much of making seems to be. I can't imagine the hours that have been spent on fine tuning extrusion settings to produce good prints. I've always been spoiled by prepped systems, but even that lets me appreciate all the aspects that can go wrong.
