How Much Does 1kg of Filament Cost on Average?

Current 1kg filament price ranges for common 1.75mm FDM materials, using typical single-spool online pricing in USD as the baseline.

Filament Type	Typical 1kg Price	Common Budget or Bulk Range	Premium or Specialty Range	Typical 1kg Length at 1.75mm	What Usually Raises the Price
PLA	$18–$28	$11–$20	$25–$40	About 330–340 m	Matte finish, silk blend, PLA+, tighter diameter control, color additives
PETG	$19–$30	$18–$25	$28–$45	About 320–330 m	High-flow formula, translucent colors, outdoor-use additives, drying quality
ABS	$19–$27	$18–$23	$30–$55	About 390–405 m	Low-odor blends, pro-grade consistency, heat-use positioning
ASA	$25–$38	$23–$30	$35–$55	About 375–395 m	UV resistance, outdoor-use formulation, controlled shrink behavior
TPU	$30–$55	$27–$40	$50–$80	About 335–350 m	Shore hardness, flexible extrusion quality, high-flow grades
Nylon / PA	$35–$75	$30–$50	$60–$120+	About 350–370 m	Moisture-controlled packaging, PA6/PA12 grade, fiber reinforcement
PC	$35–$55	$32–$45	$50–$90	About 335–350 m	Heat resistance, impact resistance, engineering-grade testing
Carbon Fiber Blends	$35–$95	$25–$50	$80–$150+	Usually 280–360 m	Carbon fiber percentage, base polymer, hardened-nozzle requirement
Support Filaments	$45–$110	$35–$70	$90–$160+	Varies widely	Solubility, humidity protection, dual-material reliability

A fair average price for a normal 1kg spool of 3D printer filament is $20–$30 for everyday PLA, PETG, and ABS. Once flexible, outdoor, engineering, carbon fiber, and support materials are included, the wider market average moves closer to $30–$45 per 1kg spool. The exact number depends on material type first, then brand tier, color, spool format, diameter tolerance, packaging, and shipping.

💵 Real Average Cost of 1kg Filament

The most useful average is not one number for every material. A 1kg PLA spool and a 1kg carbon fiber nylon spool are both “1kg filament,” yet they sit in very different price lanes.

For standard desktop FDM printing, the market usually separates into three practical groups:

• Everyday filament: PLA, PETG, and ABS usually sit around $18–$30 per 1kg spool.
• Functional-use filament: ASA, TPU, PC, and Nylon often sit around $30–$75 per 1kg spool.
• Specialty filament: carbon fiber, glass fiber, ESD-safe, high-temperature, and soluble support materials can move from $45 to well over $100 per 1kg.

PLA is the anchor price. Many current 1kg PLA listings from known filament brands land near the low-to-mid $20 range; for example, Polymaker lists many 1kg PolyLite PLA Pro colors around $23.99–$24.99, with some variants higher.[a] A budget or bulk offer can drop the per-spool number. A textured, silk, marble, wood-filled, or high-speed PLA can raise it.

PETG usually tracks close to PLA, sometimes a little higher. Polymaker’s current PETG line starts around $18.99, while MatterHackers’ MH Build PETG listing shows $24.99 for a single 1kg spool with lower bulk steps.[b] That range explains why PETG is often treated as a small price step above PLA rather than a separate premium material.

ABS can be surprisingly affordable. A current PolyLite ABS listing shows 1kg colors around $18.99–$19.99.[c] ASA usually costs more because it targets outdoor parts and UV exposure. TPU also costs more because flexible filament needs more careful compounding and feeding behavior.

🧵 Filament Price Bands That Make Sense

A cleaner way to judge price is by band. This avoids treating a basic PLA spool and a reinforced engineering spool as if they should cost the same.

Practical price bands for judging whether a 1kg filament spool is low-cost, normal, premium, or specialty-grade.

Price Band	Typical 1kg Price	What It Usually Means	Common Examples	Best Use Case
Low-cost	$10–$18	Bulk sale, refill format, limited colors, or lower-margin everyday material	PLA, basic PETG, promo spools	Draft prints, prototypes, color tests, large decorative parts
Normal shelf price	$18–$30	Standard 1kg spool from a known brand or retailer	PLA, PETG, ABS	Most hobby, school, design, and workshop printing
Premium everyday	$30–$45	Better finish, specialty pigment, tighter QC, outdoor use, or high-speed formulation	Matte PLA, ASA, premium PETG, PLA-CF	Finished parts, display pieces, outdoor brackets, cleaner surfaces
Engineering	$45–$80	Higher heat, higher stiffness, flexible behavior, or moisture-controlled handling	TPU, PC, Nylon, PA-CF, PET-CF	Functional parts, fixtures, flexible components, heat-exposed parts
Specialty	$80–$160+	Soluble support, ESD-safe, flame-retardant, high-temp polymer, or advanced composite	PVA/BVOH, PPA-CF, PC-FR, ESD-safe materials	Multi-material work, production aids, demanding technical parts

The normal shelf price is where most buyers spend their money. It is also the cleanest band for estimating monthly filament cost because the majority of common print jobs still use PLA, PETG, or ABS.

⚖️ Why 1kg Filament Prices Change So Much

Filament pricing is not only about raw plastic. The spool price includes resin, additives, extrusion control, drying, winding, packaging, color consistency, tolerance control, seller margin, shipping weight, and returns risk. For flexible or moisture-sensitive materials, handling costs rise.

Material Resin and Additives

PLA is usually cheaper because it is easy to extrude, easy to print, and sold in large volume. PETG adds toughness and chemical resistance, but still stays close to PLA in many stores. ABS is low-cost as a polymer, yet print setup can require a heated bed and enclosure, which affects total user cost rather than only spool price.

TPU, Nylon, PC, and reinforced materials cost more because the base polymer and compounding process are more demanding. Carbon fiber blends add chopped fiber, wear-tested production steps, and extra drying care. A 20% carbon-fiber nylon product, for example, is a different cost class from a decorative PLA blend; Polymaker’s Fiberon PA6-CF20 listing describes a PA6 nylon filament with 20% carbon fiber and a starting price around $39.99.[d]

Diameter Control and Roundness

A clean 1.75mm filament is not just “thin plastic.” It must be extruded at a controlled diameter, cooled evenly, measured, and wound without tangles. Better control reduces extrusion swings, weak layers, blobs, under-extrusion, and mid-print stoppages.

Tolerance is money. A spool with tighter diameter control may cost more, but it can save time when long prints run overnight. For small models, the difference may feel minor. For a 20-hour print, it matters.

Moisture Protection and Packaging

PETG, TPU, Nylon, PC, and support materials can absorb moisture from the air. Wet filament may string, pop, bubble, weaken layers, or leave a rough surface. Some brands spend more on vacuum packaging, desiccant, stronger bags, and shipping protection.

Moisture-sensitive materials also create a hidden cost: drying. A spool that costs $5 less but needs more rescue drying is not always cheaper in real workshop time.

Spool, Refill, and Bulk Format

Not all 1kg listings include the same hardware. Some include a plastic spool. Some are cardboard. Some are refill coils meant for a reusable spool. Refill formats can reduce cost, but only when the printer’s spool holder, AMS-style system, or dry box accepts them cleanly.

📏 Cost Per Meter of 1kg Filament

Filament is sold by weight, but printers consume it by length and volume. A 1kg spool of PLA is not the same length as a 1kg spool of ABS because density changes the amount of plastic per meter.

The simple calculation is:

Cost per meter = spool price / estimated meters on the spool

For 1.75mm filament, a practical planning estimate is:

• PLA: about 330–340 meters per 1kg
• PETG: about 320–330 meters per 1kg
• ABS: about 390–405 meters per 1kg
• ASA: about 375–395 meters per 1kg
• TPU: about 335–350 meters per 1kg
• Nylon: about 350–370 meters per 1kg

That means a $24 PLA spool at roughly 335 meters costs about 7.2 cents per meter. A $25 ABS spool at roughly 400 meters costs about 6.3 cents per meter. Weight price alone does not tell the full story because density changes real length.

Estimated cost per meter for common 1kg spool prices, using typical 1.75mm filament length ranges.

Material	Example 1kg Price	Estimated Length	Approx. Cost Per Meter	Planning Note
PLA	$24	335 m	$0.072/m	Good baseline for general cost planning
PETG	$25	325 m	$0.077/m	Slightly more per meter than PLA at the same spool price
ABS	$23	400 m	$0.058/m	Often low per meter, but print setup may add cost
ASA	$32	385 m	$0.083/m	Higher spool price, useful for outdoor parts
TPU	$40	340 m	$0.118/m	Flexible behavior is the real value, not low material cost
Nylon-CF	$60	320 m	$0.188/m	Better judged by part performance than by meter cost

Why Density Matters in Real Buying

Two 1kg spools can have different lengths by 60–80 meters. That is enough for several small models or one medium prototype. If a slicer estimates filament in grams, spool weight pricing is convenient. If the slicer estimates meters, density and diameter become more visible.

The cleanest cost model uses grams, not meters:

Material cost per print = spool price × print weight in grams / 1000

A 75g PLA print from a $24 spool costs about $1.80 in material. The same 75g print from a $50 TPU spool costs about $3.75. Same weight. Different material purpose.

🧮 Cost Per Print From a 1kg Spool

A 1kg spool contains 1,000 grams of filament. In slicer terms, that is enough for many small parts, several medium parts, or one very large model. The average spool price only becomes useful when it is translated into part cost.

Example print costs from one 1kg spool at different spool prices and model weights.

Print Weight	$20 Spool	$25 Spool	$35 Spool	$50 Spool	Typical Print Type
10 g	$0.20	$0.25	$0.35	$0.50	Clip, small test piece, calibration token
50 g	$1.00	$1.25	$1.75	$2.50	Phone stand, small bracket, tool holder
100 g	$2.00	$2.50	$3.50	$5.00	Medium functional part or display object
250 g	$5.00	$6.25	$8.75	$12.50	Large organizer, enclosure panel, prop section
500 g	$10.00	$12.50	$17.50	$25.00	Large multi-hour print or thick functional part

For small prints, a premium spool may only add a few cents or dollars. For large prints, the difference becomes obvious. That is why many users keep two shelves: low-cost PLA or PETG for drafts, then better-matched material for the final part.

How Many Prints Are in 1kg?

The number depends on infill, walls, support, brim, purge waste, and failed starts. Still, these rough counts work for planning:

• 10g mini parts: about 90–100 pieces after normal waste
• 25g small parts: about 35–40 pieces
• 50g utility parts: about 18–20 pieces
• 100g medium parts: about 9–10 pieces
• 250g large parts: about 3–4 pieces
• 500g very large parts: about 1–2 pieces

Waste matters. Multi-color printing, support-heavy models, failed first layers, purge towers, and calibration tests can take 5–30% of a spool depending on workflow. The filament price is only the clean part of the math.

🧪 Material Notes by Filament Type

PLA Cost: The Usual Baseline

PLA is the easiest material to price because it is widely sold, widely used, and available in many finishes. A normal 1kg PLA spool often sits around $18–$28. Budget offers can go lower, while PLA Pro, matte PLA, silk PLA, high-speed PLA, and color-effect blends can move above $30.

PLA is usually the best material for comparing brands because print difficulty is low and the price range is narrow. If a brand’s PLA is far above the normal band, the extra cost should be tied to something visible: better winding, color finish, stronger blend, recycled content, refill convenience, or documented print consistency.

When Paying More for PLA Makes Sense

• The print will be visible and surface finish matters.
• The filament has a special color, silk effect, marble effect, matte look, or filled texture.
• The printer runs fast and needs a high-flow PLA.
• The spool will be used in a multi-material feeder where winding and spool edges matter.
• The project needs repeat color across several spools.

PETG Cost: Slightly Higher, Often Worth It

PETG often costs close to PLA. It is valued for toughness, layer bonding, water resistance, and a little more temperature tolerance than standard PLA. Polymaker’s PETG listing also notes drying at 60°C for 6 hours after moisture absorption and describes PETG as hygroscopic, which explains why storage can affect real value as much as sticker price.[e]

PETG is a good example of cost per usable part. A $25 PETG spool may be a better buy than a $20 PLA spool when the part needs a little flex, outdoor tolerance, or stronger layer adhesion.

ABS and ASA Cost: Low Spool Price, Higher Setup Demand

ABS can be inexpensive per kilogram, but it is not always cheap in practice. It usually needs a heated bed, controlled cooling, and a more stable print environment. The Prusa material guide lists ABS and ASA with higher nozzle and bed temperature ranges than PLA and PETG, and marks enclosure use as recommended for ASA and ABS.[f]

ASA usually costs more than ABS because it is aimed at outdoor use, UV exposure, and parts that need better weather behavior. The price gap can be justified when the print will live near windows, in a vehicle, on a balcony, in a garden, or on outdoor equipment.

TPU Cost: Flexibility Changes the Price Class

TPU sits higher than PLA and PETG because it is flexible, slower to print, and more demanding to feed. A current MatterHackers MH Build TPU listing shows $36.99 for a 1kg spool, with lower bulk tiers.[g] High-flow TPU grades can cost more; Polymaker’s TPU95-HF listing shows $49.99 for 1kg in the checked listing.[h]

TPU should not be bought only by price. Shore hardness, direct-drive compatibility, print speed, stringing behavior, and drying needs matter. A cheaper flexible filament that jams often is expensive in the only way that counts: it wastes time.

Nylon, PC, and Fiber-Filled Cost: Part Performance Pricing

Nylon, PC, and fiber-filled blends are better judged by the printed part’s job. These materials are used for stiffness, impact behavior, heat resistance, reduced creep, dimensional stability, or low-flex functional parts. The spool price rises because the resin, additives, extrusion, and moisture control are harder.

Polymaker’s Nylon category lists several Fiberon and PolyMide nylon-family products, including PA6-CF20, PA12-CF10, PA612-CF15, and PPS-GF20, with prices ranging from about $29.99 to $69.99 in that checked category view.[i] These materials are not aimed at the same user intent as a cheap PLA color pack. They are selected when the part has a job to do.

Support Filament Cost: High Price, Small Use

Soluble and breakaway support filaments can look expensive per kilogram. Many users do not consume them like normal model material. A 1kg support spool may last through many dual-material prints if it is used only at support interfaces rather than full support structures.

The price can still be fair when it saves labor, protects surface quality, or makes a complex shape printable. Store it dry. Support filaments can be very moisture-sensitive.

🛒 Buying Details That Change the Real Average

Single Spool vs Multi-Pack

Single-spool pricing is the cleanest way to compare materials. Multi-packs often lower the per-spool number, but they can trap money in colors or materials that sit unused. A five-pack is only cheaper when most of it gets printed.

• Use single spools for testing a new material or brand.
• Use multi-packs for known colors used every week.
• Use bulk spools for production jobs, not casual color variety.
• Use refills only when the spool system feeds cleanly on the printer.

Shipping and Tax

A $19 spool can become a $27 spool after shipping. A $25 spool with free shipping can be cheaper at checkout. For real comparison, use landed cost:

Landed filament cost = spool price + shipping + tax - discount

Then divide by 1kg. For 750g, 500g, or 0.5kg spools, normalize the price:

Price per kg = package price / net filament weight in kg

A $17.99 spool that contains 750g is not a $17.99/kg filament. It is about $23.99/kg.

Net Weight vs Gross Weight

A proper filament price comparison uses net filament weight, not the total package weight. The spool, bag, box, desiccant, and label do not print. Most standard listings say “1kg” to mean net filament weight, but mixed marketplace listings should be checked carefully.

Refill Filament vs Spool Included

Refill filament may be cheaper and uses less packaging. It can also be less convenient if the refill is not mounted properly. For AMS-style systems, dry boxes, or long prints, spool geometry matters. A perfect price with poor feeding is not a saving.

Color and Finish

Black, white, gray, and natural colors are often cheaper or easier to find. Special colors can cost more because pigments, glitter, pearlescent additives, glow additives, wood fibers, and metallic effects change the extrusion process. They may also require larger nozzles or slower speeds.

Diameter: 1.75mm vs 2.85mm

Most desktop printers use 1.75mm filament, and most price comparisons assume it. 2.85mm filament can have fewer color choices, fewer sale options, and different stock behavior. The weight may still be 1kg, but the length per spool is much shorter because the filament is thicker.

👤 Better Average by User Type

The average price changes when the buyer changes. A school, hobby user, prop maker, engineering shop, and print farm do not buy the same way.

Practical average 1kg filament budget by user type and common material mix.

User Type	Common Material Mix	Realistic 1kg Budget	Reasonable Buying Pattern
Beginner	PLA, occasional PETG	$18–$28	Buy one reliable PLA before testing specialty finishes
General Hobby Printing	PLA, PETG, silk or matte PLA	$22–$35	Keep normal colors cheap; spend more for visible parts
School or Makerspace	PLA, PETG, bulk color packs	$16–$28	Use bulk PLA and limit exotic materials for controlled projects
Functional Parts	PETG, ASA, ABS, TPU	$25–$50	Match material to load, heat, and environment
Engineering Workshop	Nylon, PC, CF blends, support materials	$45–$100+	Judge cost by finished-part reliability, not spool price alone
Print Farm	PLA, PETG, refills, bulk spools	$12–$24	Use known materials, tight inventory control, and repeat colors

🧾 Hidden Costs Behind a 1kg Spool

Failed Prints

Failed prints change the real cost of filament more than most buyers expect. One failed 250g print from a $25 spool wastes $6.25 in filament before electricity, time, and machine wear are counted.

A cheaper spool is not always cheaper if it raises the failure rate. This is especially true for large parts, brittle decorative blends, poorly dried PETG, tangled spools, and flexible filament on Bowden-style setups.

Drying and Storage

A dry box, filament dryer, sealed bin, and desiccant add cost. For PLA, this may be optional in many rooms. For Nylon, TPU, PETG, PC, and support materials, storage is part of the material system.

Do not compare a $20 PLA spool and a $60 Nylon spool as if they use the same workflow. They do not.

Nozzle Wear

Carbon fiber, glass fiber, glow-in-the-dark, metal-filled, and some mineral-filled filaments can wear brass nozzles. A hardened steel, hardened alloy, or ruby-style nozzle adds cost. That nozzle cost may be tiny over many spools, but it matters for someone buying one specialty spool for one project.

Print Speed

Some filament prints slower. TPU may need slow speeds. Nylon may need drying and tuning. ASA may need warm, stable printing conditions. Slower printing does not change filament grams, but it changes machine time and the value of a successful first try.

🏷️ What Counts as a Good Price for 1kg Filament?

A good 1kg price depends on the material:

• PLA: under $20 is a low-cost or sale price; $20–$28 is normal; above $30 should offer finish, consistency, or a special property.
• PETG: $19–$30 is normal; above $35 should have a clear reason such as high-flow behavior, color effect, or premium QC.
• ABS: $18–$27 is normal; higher prices often reflect pro-grade consistency, special color, or better packaging.
• ASA: $25–$38 is normal for many users; outdoor-use value is the main reason to pay more.
• TPU: $30–$55 is normal; softer grades, high-flow grades, and specialty colors may cost more.
• Nylon and PC: $35–$75 is common; high-performance grades can move far higher.
• Carbon fiber blends: $35–$95 is common, with high-temperature base polymers above that.

🔍 A Clean Way to Compare Filament Prices

Use this sequence when comparing two spools:

1. Confirm the net weight: 1kg, 750g, 500g, or another size.
2. Normalize price to price per kg.
3. Add shipping and tax to get landed cost.
4. Check material type, not just color.
5. Check whether a spool is included or it is a refill.
6. Check printer compatibility: diameter, spool width, AMS fit, nozzle type, and bed temperature.
7. Check storage needs, especially for PETG, TPU, Nylon, PC, and support materials.
8. Estimate failure risk for the print size.

This method keeps the comparison practical. A cheap spool that does not fit the printer, needs a nozzle upgrade, or arrives poorly wound is not cheaper in use.

FAQ

How much does 1kg of PLA filament cost on average?

Most normal 1kg PLA spools cost about $18–$28. Budget and bulk deals can be lower, while PLA Pro, matte PLA, silk PLA, wood-filled PLA, and high-speed PLA can move into the $25–$40 range.

Is $20 a good price for 1kg filament?

Yes, $20 is a good price for standard PLA, PETG, or ABS if the filament is from a reliable seller and the net weight is truly 1kg. For TPU, Nylon, PC, ASA, and carbon fiber blends, $20 is unusually low and should be checked more carefully.

Why is some 1kg filament $50 or more?

Higher prices usually come from the base polymer, additives, fiber reinforcement, flexible behavior, soluble support chemistry, moisture-controlled packaging, tighter extrusion control, or a smaller production market. TPU, Nylon, PC, CF blends, and support materials commonly cost more than PLA.

How many prints can 1kg of filament make?

A 1kg spool can make about 100 tiny 10g prints, about 20 small 50g prints, about 10 medium 100g prints, or about 4 large 250g prints before normal waste. Support material, purge waste, failed starts, and dense infill reduce the count.

Is filament cheaper in bulk?

Often, yes. Multi-packs, refills, and larger spools can lower the price per kilogram. The saving is real only when the material will be used before it absorbs moisture, becomes dusty, or sits unused in colors that are not needed.

Does 1kg filament always contain the same length?

No. A 1kg spool is sold by weight, not length. PLA is usually around 330–340 meters at 1.75mm, while ABS can be closer to 400 meters because it is less dense. Material density changes the length per kilogram.

What is the cheapest useful filament type?

PLA is usually the cheapest useful everyday filament for most desktop printers. ABS can also be low-cost per kilogram, but it often needs more setup control. PETG is usually a small step up in price and offers better toughness for many functional parts.
