Topic: PLA leaning?

So for now since my power supply cant manage 115 degrees and 230+ for ABS printing I am playing with PLA again.  My current print is a miniature water pump I pulled off thingiverse.  Im creating a water cooling system for funziez. (more on that later) but imtrying to print the spinning part and its the only one not coming out right! As you can see in the attached photo's the ends of the fins are stucking up and slightly leaning and it just gets worse throughout the print (.1 mm) and I JUST did my extrusion multiplier calibration immediately before this and got it spot on.  Im printing with a bed temp of 75 and an extruder temperature of 210 (E3D Extruder (which I love!)).  And suggestions gentlemen(or possibly ladies?  I can easily trim it but I would prefer straight up thin walls as best as I can while printing.  Thanks!

Re: PLA leaning?

It may just be me, but my suggestion would be indented paragraphs. ... To be honest, the message was hard to read.



Are you saying that you feel the print is overextruding and that is causing the upcurl on the print? This can sometimes occur just because the printer takes a bend at the tip of the part and just like with circles, bends tend to have slightly extra material.


But I don't quite know if that's what your problem with the print is anyway.

Re: PLA leaning?

I've only had my SD2 since November, but I have more experience experimenting with PLA.
PLA requires a fan to cool the filament. In my best prints, I used a 40mm fan to cool the filament as it is laid down. I also had better success when I removed much of my acrylic case to allow more ambient temperature to aid cooling. Also, on an E3D, you may want to try dialing the temp back to about 205 and 75 for bed temp...but I usually kill the bed heat after a layer or two.
Thingiverse is Thingiverse, and the file may not have been slicing right, or, if only a printed image is shown, it may be missing instructions to get the desired effect displayed. Idk...I have not seen the Thing.

If you do not have a fan for your extruded filament, I can recommend two:
http://www.thingiverse.com/thing:252918  ...30mm fan for E3D and 40mm strictly for printed filament. MK5 body
http://www.thingiverse.com/thing:211657  ...this one divides the airflow, but only requires one 40mm fan. Very difficult to print without rotating and using supports. MK4 body

Printit Mason and Printit Horizon printers
Multiple SD2s- Bulldog XL, E3D v5/v6/Lite6, Volcano, Hobb Goblin, Titan, .9 motor, Lawsy carriages, direct Y drive, fishing line...the list goes on
Filawinder and Filastruder #1870.....worth every penny!
