I've been using Makergeek's PLA for awhile with pretty good results until I saw the attached print. I am guessing the change in color is due to moisture in the filament. I had only left the roll out for less than a week, but I don't think its been overly humid (we did have one good rain during the week.) Has anyone else had this kind of experience with their filament? https://reprap.org/forum/read.php?4,503982,503982#msg-503982 Sun, 19 Jul 2026 18:19:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,503982,504211#msg-504211 https://reprap.org/forum/read.php?4,503982,504211#msg-504211
I think it might be more reasonable that some other colorant/dirt/chaff or something was loaded into the machine or an improper color feed occurred. Pondering it for a bit, do you have more of the filament and is it still exhibiting the problem? You should be able to visually check the material and see if it is discolored going into the extruder. If it is - the filament is most likely to be blamed. This could happen from a clogged color mixture resulting in improper and unequal color over the print - and likely this would be isolated from others.

From the picture it seems like the color issue "resolved itself" at the end of the print. Unless you printed it upside down... the end of the print matches the vase color from before and the beginning was discolored to begin with - getting very severe after about 30-35 layers in and started resolving itself by layer 55. Then the last half of the print seems to be normal and unless I am mistaken - others should be from now on.]]> Chris Rap Reprappers Fri, 01 May 2015 21:34:53 -0400 https://reprap.org/forum/read.php?4,503982,504196#msg-504196 https://reprap.org/forum/read.php?4,503982,504196#msg-504196
Can you explain more about the first layer being spotty?]]> Blue Ice Reprappers Fri, 01 May 2015 20:15:29 -0400 https://reprap.org/forum/read.php?4,503982,504167#msg-504167 https://reprap.org/forum/read.php?4,503982,504167#msg-504167 greggo Reprappers Fri, 01 May 2015 17:52:00 -0400 https://reprap.org/forum/read.php?4,503982,504092#msg-504092 https://reprap.org/forum/read.php?4,503982,504092#msg-504092 o C. I print any lower and first layer is spotty. I have my heated bed at 55^o C. I have another roll of blue from same company and I can print it at about 200^o C no problem. Unless I had a LOT of burnt material in there I doubt that is the problem. I was printing all the x-axis plastic pieces for a prusa i3, so about an 8 hour print. The darker reddish color is where the print started. The lighter red is the later layers. Every single printed piece had the same issues at about the same height.

I contacted makergeeks about the issue just to see what they would say. It seems like they are as perplexed as I am, but their first question was hotend temperature. This is a print of the same material a few days prior with the exact same temperature settings.]]> dbrewski Reprappers Fri, 01 May 2015 13:34:09 -0400 https://reprap.org/forum/read.php?4,503982,504070#msg-504070 https://reprap.org/forum/read.php?4,503982,504070#msg-504070 Blue Ice Reprappers Fri, 01 May 2015 13:03:21 -0400 https://reprap.org/forum/read.php?4,503982,504028#msg-504028 https://reprap.org/forum/read.php?4,503982,504028#msg-504028 ggherbaz Reprappers Fri, 01 May 2015 11:15:37 -0400 https://reprap.org/forum/read.php?4,503982,503991#msg-503991 https://reprap.org/forum/read.php?4,503982,503991#msg-503991
