How do I print Nebula HTPLA?

HTPLA prints like PLA. Use typical build surfaces with Magigoo for improved adhesion & release. When unwrapping a spool, secure loose filament end in your fingers, cardboard spool side corrugation, or 3d printer extruder to avoid loops & tangles.

HTPLA is not abrasive. Max particle size is 0.1 mm. 0.6 mm nickel plated brass nozzle & heater block sock recommended for more reliable printing. A small gap between 1st layer extrusions helps avoid restriction. Choose 2 mm internal diameter tubing like Capricorn TL (light blue) w/ no play at connections. XS (dark blue) is
A starting point for typical 3D printers like Prusa or Creality w/ 0.6 mm nozzles is 0.63 mm extrusion width, 0.25 mm layer thickness, & 20+ mm/s speed for 3+ cu mm/s volume rate w/ 3 walls & 5 top/bottom layers
Choose the lowest fan setting for a good surface (typically 20-60%). Avoid fan speed changes, cooling slowdowns, overlaps, & gap fill. Choose infill
Consider a single wall part to verify flow, layer adhesion, & extrusion width. Adjust temp for inner-layer adhesion & flow to match physical extrusion width to software setting. Need help printing? We're here for you!
