Voron Best Filament Brands Guide — Top Manufacturers for Every Material

Materials Comparison Buying Guide

The right filament makes or breaks your Voron prints. Quality issues — diameter inconsistency, moisture content, contamination — waste hours of print time and produce parts that look rough or fail under load. This guide evaluates the best filament brands for each major material, with a focus on what matters for Voron owners: dimensional consistency, printing temperature range, layer adhesion, and cost per kilogram. We also cover China-direct sourcing strategies for builders on a budget. Last updated: May 2025.

What to Look for in Filament for Voron Printers

Voron printers can handle almost any material, but not all filament is created equal. Here's what to prioritize:

• Diameter tolerance: +/-0.02mm or better. Cheap filament with +/-0.05mm causes extrusion inconsistency visible on flat surfaces.
• Spool winding: Neat, consistent winding prevents snags and tangles during long prints.
• Moisture packaging: Vacuum-sealed with desiccant. Wet filament, especially nylon and PC, produces bubbly, weak prints.
• Batch consistency: The same color and material from the same brand should print identically across different spools.
• Printing temperature range: A wide range gives you more flexibility to dial in the perfect temperature for your hotend and chamber.

Best ABS Filaments

ABS is the primary structural material for Voron printers (parts, panels, structural components). It requires a chamber temperature of 45-60C and good ventilation.

eSun ABS+ (Premium Pick)

The gold standard for Voron parts. eSun ABS+ prints at 230-260C, has lower shrinkage than standard ABS, and produces matte, uniform surfaces. Layer adhesion is excellent — printed parts are nearly as strong as injection-molded ABS. Diameter tolerance is +/-0.02mm. Cost: approximately $22-28/kg.

Verdict: The default recommendation for printing Voron functional parts. If you can only buy one ABS brand, make it eSun ABS+.

Polymaker PolyLite ABS

Polymaker's offering is slightly more expensive ($28-34/kg) but offers superior impact resistance and lower odor than standard ABS. Prints at 240-260C with a bed at 90-110C. The spool winding is the best in the industry — no tangles, ever. Color consistency across batches is exceptional.

Verdict: Best for parts that need maximum toughness (toolhead carriages, gantry mounts).

Kexcelled (China Direct, Budget Pick)

Available on Alibaba/1688 for $10-14/kg shipped (bulk orders of 10kg+). Quality is surprisingly good — +/-0.03mm tolerance, prints at 230-255C. The main downside is color consistency between batches (slight shade variations).

Verdict: Excellent value for printing non-structural parts or for builders who need 20+ kg of ABS for a full Voron print set.

Extrudr GreenTEC Pro (Eco Pick)

Not technically ABS, but a bio-based alternative with similar strength and print characteristics. Prints at 220-250C with minimal warping. Layer adhesion is slightly below eSun ABS+ but still very good. More expensive at $35-40/kg.

Verdict: Great if you want eco-friendly materials. Not cost-effective for large Voron part sets.

Best PLA Filaments

PLA is used for Voron enclosures, jigs, fixtures, and prototyping. Since Vorons are enclosed, PLA is generally not used for functional parts that experience heat.

Polymaker PolyTerra PLA

Matte finish, excellent layer adhesion, and available in 30+ colors. Prints at 190-220C with no enclosure needed. The cardboard spool is recyclable. Cost: $20-24/kg.

Verdict: Best all-around PLA for Voron accessory printing.

Overture PLA Pro (PLA+)

Tougher than standard PLA with better impact resistance. Good for jigs and tools that get handled frequently. Prints at 200-230C. Cost: $18-22/kg.

Verdict: Best for functional PLA prints that need more toughness than standard PLA.

Sunlu PLA Meta

Silk-like finish, high flow rate (good for fast Voron printing). Prints at 190-220C. Slightly brittle compared to Overture or Polymaker. Cost: $16-20/kg on Aliexpress sales.

Verdict: Good budget option if bought on sale. Not for structural parts.

Best PETG Filaments

PETG is popular for Voron enclosures and parts that need better temperature resistance than PLA but don't require the full enclosure setup of ABS.

Prusament PETG

Prusa's in-house filament. +/-0.02mm tolerance, beautiful surface finish, and exceptional batch consistency. Every spool comes with a QR code linking to the quality test results. Prints at 230-260C. Cost: $30-35/kg.

Verdict: The best PETG available, but expensive. Worth it for parts where aesthetics matter.

Overture PETG

Reliable, consistent, and affordable. Prints at 230-250C with good layer adhesion. Slightly more stringing than Prusament but easily cleaned up. Cost: $18-22/kg.

Verdict: Best value PETG. The default recommendation for most Voron owners.

Best PC (Polycarbonate) Filaments

Polycarbonate requires a heated chamber (50-70C) and high nozzle temperatures (260-310C). It's used for Voron parts that need maximum strength and heat resistance.

Polymaker PolyMax PC

The most reliable PC filament on the market. Prints at 260-290C with a bed at 100-120C. Layer adhesion is phenomenal — prints are virtually unbreakable by hand. Requires a hardened steel nozzle (abrasive). Cost: $45-55/kg.

Verdict: Best PC for Voron structural upgrades. Worth the premium for critical parts.

eSun ePC

More affordable PC option at $28-35/kg. Prints at 260-300C. Slightly more prone to warping than PolyMax PC but still very good. Requires careful drying (80C for 8 hours minimum before printing).

Verdict: Good budget PC. Must be dried thoroughly before each use.

Best Nylon Filaments

Nylon is used for Voron parts requiring toughness, wear resistance, or flexibility. It needs a chamber (50-70C) and is extremely hygroscopic.

Taulman3D 910 Nylon

The most popular nylon for Voron. Low shrinkage, great layer adhesion, prints at 250-270C. Requires drying before every print (70C for 12 hours). Cost: $40-50/kg.

Verdict: Best all-around nylon for Voron applications.

Polymaker CoPA Nylon

Excellent dimensional stability and very low moisture absorption compared to other nylons (still needs drying though). Prints at 250-280C. Cost: $40-48/kg.

Verdict: Good alternative to Taulman with slightly easier handling.

Best TPU/TPE Filaments

Flexible filaments are used for Voron feet, vibration dampeners, and seals. Requires a direct-drive extruder (Bondtech, Galileo, etc.) for reliable feeding.

NinjaTek NinjaFlex

The gold standard for flexible filament. Shore 85A hardness, prints at 220-250C, very slow speed (20-30mm/s). Excellent layer adhesion. Cost: $35-45/kg.

Verdict: Best for high-quality flexible parts. Slow print speed required.

eSun eTPU

More affordable flexible option at $22-28/kg. Shore 95A — slightly stiffer than NinjaFlex but easier to print. Prints at 220-250C at 30-40mm/s. Good for Voron feet and seals.

Verdict: Best value TPU. Stiffer shore hardness makes it more forgiving for beginners.

China Direct Sourcing (Budget Builders)

For builders printing an entire Voron part set (1-2kg of filament), buying from Western distributors is fine. But for production runs or multiple printers, China-direct sourcing on Alibaba, 1688, or Taobao can cut costs by 50-70%.

Recommended China Direct Brands

• Kexcelled (Shenzhen): ABS, PLA, PETG. Minimum order typically 10kg. Quality is 80% of eSun at 40% of the cost.
• Kingroon: Budget ABS and PLA. Best for non-structural parts. 10kg orders available on Aliexpress.
• Geeetech: Widely available on Aliexpress. ABS quality is decent for the price ($12-16/kg).
• IIID Max: Good PETG and PLA. Their ABS is average. Available on Amazon and direct.

Tips for China Direct Orders

• Always order a sample spool first before buying 20kg. Color and diameter vary between batches.
• Specify +/-0.02mm tolerance in your order notes. Many factories default to +/-0.05mm.
• Use sea shipping for orders over 50kg — it's 5-10x cheaper than air but takes 30-45 days.
• Pay via PayPal or credit card for buyer protection. Wire transfers offer no recourse if the quality is poor.
• Factor in customs duties (typically 5-8% for filament imported to the US/EU).

Drying Recommendations

Wet filament is the most common quality issue. Always dry filament before printing, especially hygroscopic materials:

• ABS: Dry at 65C for 4-6 hours. Stable after drying for 2-3 days in a dry box.
• PLA: Usually printable straight from vacuum pack. Dry at 45C for 4 hours if needed.
• PETG: Dry at 65C for 6-8 hours. Absorbs moisture quickly — print within 24 hours of drying.
• PC: Dry at 80C for 8-12 hours. Must be printed directly from a dry box.
• Nylon: Dry at 70-80C for 12-24 hours. Must print from a sealed dry box with desiccant.
• TPU: Dry at 50-60C for 4-6 hours. Less critical but improves surface quality.

Conclusion

For most Voron builders, eSun ABS+ is the default recommendation for structural parts, Overture PETG for general purpose printing, and PolyTerra PLA for accessories. If you need maximum toughness in specific parts, upgrade to Polymaker PolyLite ABS or PolyMax PC. For budget bulk printing, Kexcelled from China direct offers unbeatable value. Always dry hygroscopic materials before printing and store filament in sealed containers with desiccant. The best printer in the world produces mediocre prints with bad filament — don't skimp on the material that touches your print surface.
