To ensure that no external mechanical factors affected the printing process, I removed the Filament Enclosure. Lesson learned: A Filament enclosure is a great thing to have, but it's essential to ensure there's no friction between the enclosure and the filament spool, allowing the filament to exit easily! Two spools move differently in an enclosure based on the type of material and shape. If in doubt, print without an enclosure! I can't say that the dehumidifier was the number one reason for the good final print, but I can say it was helpful. From now on, I will dry any filament prior to use on a print. 29 OCT 2 A great print with ABS filament was achieved since I have the dehumidifier; the ABS filament spent 4-5 hours in "treatment" at 60C. Therefore, the design is out of question for now. CR10 settings: n 0.4, f-abs, n245c, b100c, lh 0.2, if 60%, wt 1mm, tbt 1mm, f 100%. The print was done in an enclosed space. I will dry more ASA filament and try again without the Filament Enclosure. 29 OCT 1 After drying the filament for more than 5 hours at 60C, I made another print test with the same results - a bad print. It's possible that a different problem exists. I started a new print with ABS to see if the issue was with the design of the part. I need to consider that the Filament enclosure may make it harder for the printer to feed the filament, resulting in delamination of the part. Will see! 28 OCT After two unsuccessful trials with fresh filament from sealed manufacturer bags containing silica gel, I decided it was time to upgrade my printing equipment. Welcome my new ex fruit dehumidifier and fresh 3D Print Filament Dryer! There are many videos on YouTube, so I won't bother you with assembling and modifications. Thanks to Joe Mike! On a separate print using my HIGH TECH THERMOMETER, I measured the temperature inside the print enclosure - with a bed of 100C, the air temperature was around 70C. I didn't record the enclosure temperature at that time, but it was over 70C since the bed was set for 110C. CR10 settings: n 0.4, f-asa, n245c, b110c, lh 0.2, if 60%, wt 1mm, tbt 1mm, f 0%. The print was done in an enclosed space. Lesson learned: If the filament isn't dry, it doesn't matter if the rest of the conditions are proper for a good print; the final result will be bad! Never assume that fresh from the box means the filament is dry and ready for use.
