    Question Flash Forge Creator Pro PETG printing Help

    Hello Everyone, Thank you in advance for the help . I have attempted for the last 30 days to get this right but i cant seem to get it right. I can print the designs on PLA with no problem but when I go to print on PETG its a disaster . The best combination I was able to find was to print at 240 C on both extruders, cooling fans all the way off , plate at 75. I also slowed the print down to 50 and that helped some. I am using flash print and I cant seem to identify any other variables . See pictures PLA on right and PETG on left

    picture is small and hard to see.. but looks like you have bubbles in the PETG?.. If so you are too hot.. drop it to 230C which is where I print eSun PETG all the time, no fan slow it down to 40mms or slower

    Thank you. Yes I'm getting bubbles. What travel speed would you suggest ? At 230 the print was coming out worse. Ill do a print so I can show

    May be wet PETG and needs to be run in a dehydrator for 8-10 hours..

    I purchased the sunlu filament from Amazon. It came pretty sealed . I don't have a dehydrator . Is there a brand you would recommend that works well for you

    I don't use petg for anything that has detail.. mostly make mechanical type parts.. I use esun all the time and amazon brand once with good luck, but I dry everything if I have a hint of problems..

    Thank you , what other material would you recommend then that is uv resistant and holds details better ?

    PLA is actually fairly UV resistant, much more UV resistant than ABS. As an experiment, I hung several PLA prints on a south-facing fence post where they were fully exposed to the sun and the weather. They've been there nearly three years and have shown no sign of yellowing, and only a slight fading. On the other hand, PLA can warp in the hot sun. I've had PLA warp in a car parked in the sun on a hot day.
