I am printing a test part with new filament material and experienced curling at the corner of the part. I started with eSun PLA+ settings as a starting point with a plate temp of 55℃. Nozzle temp is 220℃.
If I increase the plate temp will this reduce the curl?
There isn’t a simple answer. Yes, lowering temps on the filament will cause less shrinkage but at the cost of layer adhesion depending on filament. Then there is also the option of increasing the plate temp to ensure stiction. There is a goldilocks zone that only experimentation can confirm. However, employing brims almost always works so I would start of with that first.
Kinda curious which/what filament you’re using. Seaweed or Alge based?
Haven’t used either but am a little curious.
Using my new seaweed derived filament I am getting edge curl and loss of adhesion to the build plate. I am using a textured PEI Plate and have increased the temperature to 70℃. I have also lowered the extrusion temperature to 210℃. This has improved things but eventually the part detaches as the curl increases. The curl is more pronounced at the front of the printer closest to the door.
I assume a smooth PEI plate plate would be better than textured and should I apply glue to the plate.
In the photos one corner of the part is ok with the front corners showing the most curl.
I have no experience with the material but the model looks to be more the problem no matter the material and think it needs to be treated similarly. Brim with zero gap, glue on a smooth plate would be my suggestion to start with.
It could be that you have a nice cool breeze passing over the plate, causing the material to shrink, usually identified by the same corners lifting on all your prints.
Wow seaweed? So cool. Bed adhesion is going to be better on the smooth PEI plate with glue stick. you should also add “brim” 3mm is usually enough to help out a lot.
When the model “lifts” off from the plate; it can also be that the build plate itself “lifts” off because the magnets are not holding it down. So no amount of “brim” or glue stick can solve a model that can pull the build plate off the magnet base.
Using the whole build plate is unrealistic, you won’t always be able to utilize any arbitrary shape in the build rectangle. A circular limit (don’t use the diagonal) is safer. But you might be able to make it work good luck!
I don’t think that is it. I have P1S fully enclosed printer.
Thanks for the reply. I will try both ideas and see what works.
Thank you for the suggestions. I will try them both.
Is there any info on the filament?
Attached is a photo of the top surface of a test part I am printing with a seaweed based polymer filament. As the printing proceeds the layers get more “furry”. Can this be reduced by,
- Increasing the nozzle temp
- Slowing the speed,
- increasing the plate temp,
- changing the volumetric speed
Any ideas would be welcome.
