I had a failure again last night because of a nozzle clog after 17 hours of printing. This was my second try at the same part. I have made three of these with no problem. I assume it was because I used a lower quality PLA. I get good prints with it most of the time, but it looks like when I get failures, they are due to variations in the filament composition.
I also have problems with ABS. I get reasonable parts sometimes, if they are small or I get lucky. I believe the high amount of part warping when printing with ABS is also due the low quality filament I bought. Same issues. Larger parts warp pretty badly or delaminate. Even with real good build plate bond, I still have problems with ABS.
Can anyone recommend a reasonable priced PLA and ABS 1.75 filament that has been working well for them? My main colors are white, red, blue and black.
I have heard colors can affect the print.
I've looked at Anthony's videos, but just wanted more opinions.
Thanks,

ABS needs to cool slowly or it will warp... That's why you need a heated build plate and chamber...
@ANDY ROID What printer do you have?....
Regarding ABS,I have a heated bed, and tried covering the machine to keep in the heat. I have tried running the bed as low as 70 and as high as 110 and find the problem never goes away. I have the filament as low as 190 and up to 245.
I even mess with the speeds. I would have to get my book to give you those numbers, but I have slowed it to about 75%. I will admit sometimes my tape breaks loose and I get a warp that way, but often I will get a delamination.
I want to have a good brand of filament so I have a good idea of something being constant. Then I can try changing settings.

In my R2D2 post is a picture of my printer. Maybe I will make an enclosure like you have done for ABS. I normally just cover it with a fire resistant cloth to keep the heat in. What temperature do you keep the chamber at?
Ron R
I am going to try your suggestion of enclosing the build area. What kind of temperature do you maintain in the build area. I may consider using a heat gun with a thermostat if necessary. We used a similar method when bonding areas on aircraft parts, We would bag the part and heat it with a heat gun and controller to cure it. I think it is overkill, but I really want to make some larger parts out of ABS.

I finally got a good, not great print of the foot for my R2D2. I will resin it for a good finish.

I went out and bought another piece of glass from Lowes and made up an Acetone ABS slurry. The liquid is the consistency of milk. I applied it twice to a cold heat bed and let it dry. I took an old towel and placed it over the machine to hold in the warmth from the machine when running. I ran some ABS test parts which warped in the past. They came out nice and flat.
I ran a full bed of parts the same way, which was a 22 hour run. They came out great. Thanks to all that helped me with the elimination of a haunting problem.
I plan to take the advice given, when I order my next batch of filament. Sounds like the brands suggested is the way to go.
