Cheapest 3D Printer Filament Reddit: Top 5 Brands Voted by the Community

What Reddit Says About Cheap Filament

r/3Dprinting users consistently recommend a handful of budget brands. The community values real-world experience over marketing. When someone asks "what's the cheapest filament that actually works," the same names appear: SUNLU, eSUN, JAYO, Inland, and Kingroon. Each has different strengths. SUNLU gets the most praise for bulk PLA and PETG. eSUN is called "the most reliable cheap Chinese filament" by many. Inland (Micro Center's house brand, made by eSUN) is trusted by US users who have a store nearby.

The caveat: Reddit also warns against the absolute cheapest no-name brands. Threads mention inconsistent diameter, tangles, and failed prints. The consensus: spend $14–18 per kg on a known brand rather than $8–10 on mystery filament. Our price comparison tool tracks these brands across Amazon, eBay, and manufacturer sites so you can spot real deals.

Brand-by-Brand Breakdown

1. SUNLU

SUNLU gets the most praise on Reddit for bulk filament. Users report PLA at $12.99–17.99 per kg, with 60+ colors for PLA+. SUNLU PLA Meta is noted for high-speed printing (up to 600 mm/s) with minimal stringing. The main caveat: some users say they do not carry all colors consistently. SUNLU bulk packs (4–10 kg) often undercut Amazon single spools by 15–25% when bought from their direct store. Our tool tracks SUNLU across Amazon, eBay, and sunlu.com.

2. eSUN

eSUN is described as "the best value for money filament" in multiple threads. Reddit users praise eSUN PETG for good layer adhesion and strength. Typical price $16–20 per kg. Diameter tolerance ±0.03 mm. eSUN is widely distributed—Amazon, Micro Center, and direct. For PETG specifically, eSUN and OVERTURE are the two most recommended budget options. See our best PETG guide for a full comparison.

3. JAYO

JAYO (SUNLU's budget sub-brand) gets mixed but positive reviews. Reddit users say JAYO is "OK for the price" for PLA. PETG is more mixed—some report poor quality or inconsistent results. JAYO PLA+ and PLA often hit $10–12 per kg in 4-pack bundles. At that price, the community considers it acceptable for prototypes and non-critical prints. Buy one spool to verify before committing to 5–10 kg. JAYO is frequently available on Amazon and eBay.

4. Inland

Inland is Micro Center's house brand, made by eSUN. Reddit users near a Micro Center trust it for "cheap and fairly consistent" filament. Wide range of colors and materials. Inland PLA and PETG run $16–20 per kg. The catch: you need a Micro Center nearby, or you pay shipping. Inland is also sold on Amazon and eBay under the Inland name—same product, often slightly higher price than in-store. For US users without a Micro Center, Inland on Amazon is still a solid budget choice.

5. Kingroon

Kingroon appears less often than the others but gets positive mentions. Reddit users recommend it for budget PLA and basic PETG. Typical price $12–16 per kg. Kingroon is known for budget printers and filament—both are discussed. For filament, the sentiment is "acceptable for the price" with fewer detailed reviews than SUNLU or eSUN. If you find a good deal, try one spool first. Kingroon is often on Amazon and AliExpress.

Brands to Avoid

Reddit warns against the absolute cheapest no-name brands. Threads mention inconsistent diameter (causing jams and failed first layers), tangles, and puffy bags (moisture). The rule of thumb: if a brand has no presence on r/3Dprinting and sells PLA at $8–10 per kg, be skeptical. Some users report success with GST3D and IIIDMax bulk—but those are "buy at your own risk" recommendations. The community consensus: stick to SUNLU, eSUN, JAYO, Inland, or Kingroon for budget filament. The extra $2–4 per kg is worth avoiding failed prints. See our price per gram guide for when cheap filament becomes a trap.
