Topic: trouble printing a part

I have been trying to print http://www.thingiverse.com/thing:162565/#files for days now ,I just can't  stop it from curling. I use a glass a plate. I have tried hair spray, glue,blue painters tape ect. I also have tried higher and lower bed and extruder temps. I even tried a 12mm brim. I have done a fairly flat one at 20% infill but it was recommended to be printed at +30%,do ya'll thing it best if I print it upside down? I just dont want to waste anymore filament.

Re: trouble printing a part

Two suggestions:

I had trouble printing a particularly large, thin item due to curling.  I raised the printbed temperature by 10 degrees C, and had no more problems.

Other times when I've had problems with sticking or curling, I've applied some Elmer's glue stick to the printbed.  It's worked really well for me.

Is your machine bed enclosed? Alot of my issues went away with a good sealed case.

Re: trouble printing a part

Thanks I guess I 'll try that next

Re: trouble printing a part

wicked suggestion.. but have you tried the bare build plate with kapton, and given it a *good* wipe down with acetone on a warm bed (i.e, 40-50°) ? make sure you're bed is dead level and that first layer reasonable squished down (z-height...)

Re: trouble printing a part

Ahhhh    opps I removed the kapton tape, now using a mirror with hair spray. Results to follow.The bed is level as I can get it.
Also  enclosed the printer with foam board. Fingers  Xed this will do the trick.

Re: trouble printing a part

I've had to run 110C bed temps for some ABS prints. What temperature do you use?

8

Re: trouble printing a part

I normally run a bed temp of 105.  I've used as high as 115 for a particular spool of crappy white, to keep it from curling up as it cools.

Re: trouble printing a part

this Octave white I have to run 230/ 115 to even stick.

Re: trouble printing a part

I gave this model a spin and while it's not a particularly lengthy print, it does take more than 4 hours if printed at .1mm.  So maybe in the OP's case, this is an issue of the print taking too long to print. 

Try slicing it at .3mm and printing it, and see if this helps with the curling.  This is a utilitarian piece, so perfect surfaces should not be an issue.

Re: trouble printing a part

I was just corcerned if it curled a bit would the linear bearing fit and operate properly.

Re: trouble printing a part

Do you have an enclosure?  I would print something like that totally solid at .3mm with the bed at 105 to 110.  If your enclosed let the bed warm up for a while so inside the printer is nice and toasty.  Squish the first layer as much as you can get by with and use only about 5mm brim.  setting the filament temp. too high will only complicate your issue of curling so use a temp that usually yields the best results.  Spray the glass with two or three light coats letting it dry in between.  The ABS shrinks as it cools and that should be a fairly simple print job.  So my guess is the air surrounding the print itself is too cool.
Maybe I'll go and print one quick just out of curiosity.

Edit: By upside down do you mean the way it's shown in the picture or the way it downloads the file?

Re: trouble printing a part

so far no signs of "curling" and it's set up just as I listed above.

As you can tell I have the fan off.

I will say this though...
The bearings sit in there rather loose but I am curious to hear how this works out for you.

Re: trouble printing a part

One thing that helps to prevent curling is having a nice brim, just like Ward has in this print.  I usually have a 3-4mm brim on most of my prints, and I hardly ever get any curled edges or corners, and I don't have an enclosure around my printer

Re: trouble printing a part

I just liked the one piece design as oppossed to the 3 piece. I have to  get some linear bearings to test both designs.

Re: trouble printing a part

I also like the design, simple and looks to be effective.  I tried putting bearings in though and they are way too loose to be effective.  Maybe you can wrap enough tape around them to firm things up.

Re: trouble printing a part

I had a similar problem with Lawsy's carriage ends, they were too loose for the linear bearings. 

In my particular case, I was able to simply wedge a piece of a business card under the bearing to fix the slop, and so far I have at least 100+ hours on them with out any ill effects or slop.

Re: trouble printing a part

These were way looser than that.  Either way it's not something I need to use.  I'm sure it'll work just fine and I like the snap into place from the top simplicity.

Re: trouble printing a part

ok , it's 80+F in the enclosure, hot enough? I 'll see how that does.

Re: trouble printing a part

Well that didn't work. I have run out of options. I wonder if PLA would be strong enough for this part. I read it doesn't have the tendency to curl  like ABS.

PM me and I can just send you the one I printed.

Re: trouble printing a part

The saga continues,LOL   Can someone take a look at this pic and tell me what  is causing that?The brim will start out fine then as you can see about the 3rd loop the inside starts puckering.It's like the nozzle is raising up at that point. I can't see that it is tho.The machine is calibrated best I can get it . In the past it worked well,I printed a lot of good parts.
