Filament Settings

Ready to print… stuff?  Awesome. You may be wondering what we recommend for optimal prints with our FoxSmart filament. Or you may be devil-may-care and print without heed to society’s rules and guidelines. Our filament factory sent us their recommendations and they were so goofy we ignored them completely – instead we’re offering you our humble suggestions based on our months of personal prints. For those who care for recommendations we offer the following:




* Our PLA tends to print best on lower temps. For white we recommend starting at 185° and moving up 5° if you’re not extruding well. We print at 195° when we’re printing faster and around 185° when we’re doing slower, more intricate prints.
* Your printer may like things a bit hotter (that’s a sexy printer), so run some tests to get a feel for how our filament works with your exact printer and extruder.
* For colors we recommend about 5° hotter on average. Some colors, like red, have us printing as much as 10° hotter. But for the most part we bump from 185°/190° to 190°/195° when we’re printing colors.


* FoxSmart ABS likes temps in the 240°-255° range. Hotter than some out there, but pretty normal vs. many we’ve tested. Since there are now 45,690 printers on the market, you’ll need to play around to figure out what temp settings your printer (and nozzle) like best.
* You’ll want a heated bed in the 80°-110° range to keep things from warping. You’ve been warned.
* Don’t print in your living room! ABS is a stinky plastic. Air that ***t out. Print in your garage or ventilated shop.

* Print hot – 210°-225°, so that filament cruises easily through your extruder
* Monitor it as each new print starts. Closely. It seems inevitable that I have to walk my printer by hand through the few 3-4 layers. I’ll notice layer 2 stopped printing and find filament gumming up my step motor. I pause, pull it out and start again. What tends to happen is that once the tension off the spool is perfect, the printing prints no problem, but it can take a layer or 3 to get there. We generally get no problems once we’re on layer 5+.
* Print slow – no faster than 30mm/s. Most step motors are designed to push stiff filament through, not bendy licorice whips. If you print too fast you’ll end up with filament wrapped up in your motor like taffy.


That’s about it. We know….some filament sellers have pages full of information you don’t care about. They do this because either they suck or they just want to charge more. Or they’re smarter than us. Our filament works. It’s that simple. Thread it in, set your printer temps, get that first layer down, then walk away. When you come back you’ll find something awesome.


Some have asked about the spool size. While we are working on introducing multiple spool sizes to accommodate various printer types, at the moment, the below is our current standard spool (for both 1KG and .5KG).
