What do people know about the cheaper ($25-30) filiment?
Which ones? The stuff at Micro Center isn’t bad, but the stuff on ebay tends to be crap (though not all are).
Hatchbox on Amazon is pretty much all I use for ABS and PLA. Only $23 per kg.
How about the esun I got an esun pla it seems to work great but I have nothing to compare it to
Hatchbox on amazon is big seller. Lots of people like it. I like the name, reminds me of Matchbox cars 
I’ve used a couple rolls of the eSUN. It prints hotter than the Hatchbox and is a bit more expensive so I didn’t use it for long. It’s most likely a little stronger due to the higher printing temps but I haven’t done any stress tests.
Ok thank you
Some are really good. But after some spools you might encounter diameterdifferences or even quality. For what ive seen…when you have a little experience its better off buying better filament but for the beginning its not too bad buying cheaper wones. Ive hat a spool of esun abs which was horrible. Warping like hell and it wasn even standard abs the blend was different. The same with pla. But the cheaper esun petg works ok
We bought cheap stuff off ebay and had a significant increase in problems with it clogging the nozzle.
I’ve never used a filament that cost more than $30/KG, and usually not more than ~$23/KG. Never had a problem.
Hatchbox is very good, as is Solutech.
I’ve used Hatchbox with great results, 3D solutech is good sometimes clogs in my extruder (could be my temp.)
I am trying the newcomer to Amazon, BAMTac, but so far I’m not really liking it.
I buy a lot of makergeeks stuff, usually $25 or less, prints well, and made in USA + free ground shipping if you care about that sort of thing
I just got a roll of gizmodork ABS and it worked quite well for me
Intservo, the US supplier of ESUN, has been great to work with and offer a money back guarantee if you are not happy with a spool of filament.
So far I have been really happy with their natural PLA filament. Silver also printed well but tended to be a little brittle, especially at the end. Blacks decent though if you want white, I would skip the PLA and try their newer PLA+ material, not that I have had a chance yet.
Also very pleased with the 1/4 roll of the blue PETG I bought from them. Have yet to open the white or black PETG however as I am trying to use up some PLA first.
@PrintinAddiction Same experience with 3D Solutech. Bought a couple rolls of PLA and I can’t print with it for more than 10 min without a clog.
@Adam_Steinmark try dipping the end of the filament in some canola oil before loading it in the hot end. That normally works for me.
@John-Paul_Hopman Canola oil combusts at 200 C. I don’t want to get gunk in my hotend.
