Stumbled on another one… Printed Solid’s “Jessie” filaments (PLA, PETG, and PLA silk, called “Elixir”) are also made in the US (Delaware).
PLA and PETG - $19.99/kg
“Elixir” PLA - $24.99
Don’t see any discount mentioned for buying multiple spools, but shipping is free for orders over $50.
Also, as they are apparently owned by Prusa, they have a section for US-made Prusament. I’ve never tried Prusament, but the price is way higher so I probably never will… $26.99 for a 1kg refill.
I really wish these companies would offer sample packs, or 200g spools so we could try colors and print quality without having to buy a full spool. I mean, what if I buy their red and I hate the way it looks?! Very aggravating!
I know Zyltech offers some options for samples of their rainbow/gradient silks, and very short 5m samples of their PLAs. Some of the others offer to sell you printed color swatches so you can see the colors, but you’re still stuck buying a roll to see how it prints. Frustrating.
90% of the filament I use is Atomic. There customer service is top notch and usually its same day shipping.
