Why Filament Choice Matters More Than Your Printer
You can own a $1,000 printer and still get terrible prints if your filament is bad. Inconsistent diameter, moisture absorption, and poor pigment distribution cause more failed prints than any hardware issue. Meanwhile, a $200 beginner 3D printer with quality filament produces prints that look professional.
Filament is the consumable you will buy again and again. Getting it right from the start saves you hours of troubleshooting and kilograms of wasted plastic.
We tested six popular filament brands across 200+ print jobs over three months, using a Creality Ender 3 V3 and a Bambu Lab A1 Mini. Every brand was tested in PLA (the beginner standard), and select brands were also tested in PETG and TPU.
The Three Filaments Every Beginner Should Know
PLA (Polylactic Acid): Start here. PLA prints at low temperatures (190-220C), sticks to the bed easily, produces minimal warping, and does not require an enclosure. It is made from corn starch, so it smells faintly sweet when printing. Downsides: it softens above 60C (not for car dashboards or hot environments) and is more brittle than PETG.
PETG (Polyethylene Terephthalate Glycol): The upgrade. PETG prints at 220-250C, is more flexible and impact-resistant than PLA, and handles higher temperatures. It is the go-to for functional parts, outdoor items, and anything that needs to survive some abuse. Downsides: stringier than PLA, requires more tuning.
TPU (Thermoplastic Polyurethane): The flexible one. TPU prints at 210-230C and produces rubber-like objects — phone cases, drone bumpers, gaskets. It is tricky to print because it is soft and can jam in Bowden tube setups. Use a direct drive extruder.
The 6 Best Filament Brands for Beginners
1. Hatchbox PLA — Best Overall for Beginners
Price: $22-26 per 1kg spool
Hatchbox is the Goldilocks of filament. It is not the cheapest, not the most exotic, but it prints reliably every single time with almost no tuning needed. We loaded a spool of Hatchbox PLA into both printers, used default PLA settings, and got clean prints on the first try with both machines.
What stood out:
- Diameter tolerance of +/- 0.03mm — among the tightest in consumer filament
- Every color we tested (black, white, grey, blue, red) printed identically. No color-specific tuning needed.
- Vacuum-sealed packaging with desiccant. Our spools arrived bone-dry.
- Clean spool winding. No tangles, no crossed loops. This seems minor until a tangle ruins a 14-hour print.
- 30+ colors available, including silk and matte finishes
Recommended settings (PLA):
- Nozzle: 200C
- Bed: 60C
- Speed: 50-80mm/s
- Retraction: 5mm at 45mm/s (Bowden) or 1mm at 25mm/s (direct drive)
Best for: Beginners who want zero drama. Load it, print it, done.
2. Polymaker PolyLite PLA — Best Print Quality
Price: $24-28 per 1kg spool
Polymaker takes filament more seriously than most brands. Their PolyLite line is produced with tighter quality controls, and it shows in the surface finish. Prints come out with a smooth, consistent layer appearance that Hatchbox and cheaper brands cannot quite match.
What stood out:
- Noticeably smoother surface finish on curved surfaces and gradients
- Low-odor printing — less noticeable than Hatchbox even
- Excellent bridging performance — arched structures printed cleanly at longer spans
- Spooless refill option reduces plastic waste (and costs $3-4 less per spool)
Best for: Makers who care about print aesthetics — cosplay props, display models, gifts.
3. Overture PETG — Best Budget PETG
Price: $18-22 per 1kg spool
When you are ready to move beyond PLA, Overture PETG is the easiest transition. It prints with minimal stringing at 235C, sticks to a PEI bed without glue or tape, and produces parts that are noticeably tougher than PLA. At under $20 per spool, it is also cheaper than most PLA brands.
What stood out:
- Almost PLA-easy to print. Minimal stringing at 235C nozzle / 80C bed.
- Parts survived drop tests that cracked PLA prints
- Transparent and translucent colors actually look translucent — many brands produce cloudy results
- Each spool comes with a build surface sheet (a nice bonus for beginners)
Recommended settings (PETG):
- Nozzle: 235C
- Bed: 80C
- Speed: 40-60mm/s
- Fan: 30-50% (not 100% like PLA)
Best for: Functional parts, outdoor projects, and anyone ready to step up from PLA without a steep learning curve.
4. Creality Hyper PLA — Best Value
Price: $14-18 per 1kg spool
Creality’s Hyper PLA is engineered for high-speed printing — up to 600mm/s on compatible machines. But even at normal speeds (50-80mm/s), it produces prints on par with Hatchbox at a significantly lower price. If you are burning through filament on test prints and learning projects, this is the economical choice.
What stood out:
- At $14/spool, you can experiment without worrying about wasted material
- Prints well at high speeds on Bambu Lab and Creality K1 series
- Decent color selection with 20+ options
- Good layer adhesion even at faster speeds
What could be better:
- Packaging is functional but not vacuum-sealed as tightly as Hatchbox or Polymaker
- Diameter consistency is slightly looser at +/- 0.05mm — still acceptable, but noticeable on precision prints
Best for: Beginners learning 3D printing who want to experiment without spending $25 per spool.
5. SainSmart TPU — Best Flexible Filament
Price: $25-32 per 0.8kg spool
TPU is inherently harder to print than rigid filaments, but SainSmart’s 95A hardness TPU is the most forgiving flexible filament we tested. It printed successfully on both a Bowden setup (with reduced speed) and direct drive without jamming — something we could not say for every brand.
What stood out:
- 95A Shore hardness is the sweet spot — flexible enough for phone cases, firm enough to print reliably
- Printed on a Bowden tube setup at 25mm/s without jamming (slow but it works)
- Excellent layer adhesion. Finished parts stretch without delaminating.
- Phone cases, watch bands, and drone bumpers survived real-world use
Recommended settings (TPU):
- Nozzle: 220C
- Bed: 50C
- Speed: 25-35mm/s (Bowden) or 40-50mm/s (direct drive)
- Retraction: minimal (1-2mm) or disabled
Best for: Phone cases, protective bumpers, gaskets, watch bands, and any print that needs to flex.
6. Bambu Lab PLA Basic — Best Ecosystem Filament
Price: $20-24 per 1kg spool
If you own a Bambu Lab printer, their PLA Basic is the path of least resistance. The filament has an RFID tag that the printer reads automatically — nozzle temperature, bed temperature, speed, and retraction are all set without touching a single setting. You literally load the spool and press print.
What stood out:
- Zero-config printing on Bambu Lab machines via RFID
- Print quality is comparable to Hatchbox and Polymaker
- Available in Bambu’s AMS (Automatic Material System) for multi-color printing
- Consistent quality across the 8 colors we tested
What could be better:
- Only useful on Bambu Lab printers for the auto-config feature. On other printers, it is just average PLA at a slightly premium price.
- Color selection is smaller than Hatchbox or Polymaker
Best for: Bambu Lab printer owners who want zero setup and consistent results.
Filament Storage: Keep It Dry or Throw It Away
Moisture is filament’s enemy. PLA absorbs water from the air, and wet filament produces rough surfaces, stringing, popping sounds during printing, and weak layer adhesion. PETG and TPU are even more moisture-sensitive.
Storage rules:
- Store opened spools in airtight containers with silica gel desiccant packets
- Print from a dry box if your environment is humid (above 50% RH)
- If a spool has been sitting open for weeks, dry it in a food dehydrator or filament dryer at 45C for 4-6 hours before printing
- Vacuum-sealed spools from the factory are fine until opened
A $30 cereal container with a $5 bag of silica gel works as well as a purpose-built dry box. Do not overcomplicate this.
Beginner Filament Starter Kit Recommendation
For someone buying their first printer (or first filaments), here is the kit we recommend:
- Hatchbox PLA in black and white — your workhorses for functional prints and prototypes
- One spool of Overture PETG — for when you need durability
- A filament dry box or airtight container — protect your investment
- Spare 0.4mm nozzles — $5 for a pack of 5. Nozzles wear out, especially with filled filaments.
Total cost: under $80 for enough material to print for months.
Frequently Asked Questions
How long does a 1kg spool of filament last?
It depends on what you print. A typical small project (phone stand, cable organizer) uses 20-50g. A large figurine or functional part might use 100-300g. For most hobbyists, a single spool lasts 2-4 weeks of regular printing.
Does filament color affect print quality?
Slightly. White and light colors show layer lines more than dark colors. Some pigments (especially metallics and silks) require slightly different temperatures. Black PLA is the most forgiving color for hiding imperfections.
Can I mix filament brands in one print?
Yes, as long as they are the same material type (PLA with PLA, PETG with PETG). You may need to tweak temperature slightly when switching between brands. Do not mix PLA and PETG in the same print — they have incompatible print temperatures.
Is PLA safe to use indoors?
PLA produces minimal fumes and is generally considered safe for indoor use. That said, any 3D printer should be used in a ventilated room. PETG and especially ABS produce more fumes and benefit from an enclosure with filtration.
What causes stringing and how do I fix it?
Stringing (thin hairs between printed parts) is usually caused by temperature too high, retraction too low, or wet filament. Start by dropping nozzle temperature 5C and increasing retraction distance by 1mm. If it persists, dry your filament.
