Printing glass on Ultimaker

This is only the very first test...more on: www.facebook.com/europerminutedesign www.rooiejoris.nl Print with extremely high extruder speed and a large nozzle size of 0.8mm. In sf46, the most crucial settings are: Layer thickness: 1.1mm Wall layer thickness to height ratio: 2.1 Feed rate: 45 Flow rate: 1250 In reality, I doubled these values because my stepper driver isn't set up for microstepping, but instead uses fewer steps per rotation, making it move twice as fast as normal. The extruder wheel is spinning extremely quickly! Temperature: 240 degrees Celsius UPDATE: This material is PLA, and a higher temperature will make the PLA more liquid. Be cautious when using high temperatures if your nozzle holder isn't made of PEEK. Flow and feed rate also depend on your firmware. In sf<40, I printed with a flow rate equal to 1.5 times my feed rate for normal 0.8mm prints. With my first experiments using sf>40, I obtained very high values due to my firmware still thinking it's using sf<40 settings. I'm not too skilled in software... Microstepping is disabled only for the extruder, which requires high speed due to the Ultimaker's gear system. A 0.8mm nozzle could work as well - it was originally drilled with a 0.8mm drill bit, but an ordinary closed bolt could also function. Adjustments by hand controlled the smoothness and irregularity of prints. Higher Z values resulted in more irregular surfaces.
