The price on a spool of filament is only the starting point for what a 3D print actually costs. Electricity draw over a multi-hour print, and the material wasted on failed prints, both add real money on top of the $/kg sticker price — and for long prints on a budget printer, that extra cost can easily rival the material cost itself.

This guide breaks down all three cost components with real 2026 pricing and failure-rate data, and works through two full examples. It pairs with the [3D printing filament cost calculator](/calculators/3d-printing-filament-cost-calculator), which computes all three factors together for any print.

## Quick Answer: The Three Cost Components

**Total print cost**

```
Material cost = (grams used / 1000 × price per kg) ÷ (1 - failure rate %)
Electricity cost = (printer watts × print hours / 1000) × price per kWh
Total cost = Material cost + Electricity cost
```
- Dividing by (1 - failure rate) spreads the cost of failed prints across successful ones — a 10% failure rate means roughly 1 in 10 prints fails outright, so successful prints need to cover that wasted material on average.

**2026 filament pricing snapshot by material**
| Material | Typical price per kg | Notes |
| --- | --- | --- |
| PLA | $15-$22 | Cheapest and easiest to print; most beginner-friendly |
| PETG | $18-$28 (median ~$19) | Now often price-competitive with PLA; more heat/impact resistant |
| ABS / ASA | $16-$25 (specialty ASA up to $40) | More heat-resistant but needs an enclosure and ventilation |

## Failure Rates Are the Hidden Cost

Every 3D printing hobbyist eventually prints something that fails partway through — a warped corner lifts off the bed, a layer shifts, or the nozzle clogs. That wasted filament and wasted print time is a real cost, and it scales with printer maintenance and operator experience far more than most people expect.

**Typical failure rates by experience level (FDM printers)**
| Experience level | Typical failure rate |
| --- | --- |
| Beginner (first 6 months) | 15-25% |
| Intermediate (1-2 years) | 8-15% |
| Advanced, well-maintained machine (2+ years) | 3-8% |
| Professional print farm | 2-5% |

_[Figure: Failure rate ceiling by experience level — The upper bound of the typical range narrows sharply with printer maintenance and tuning experience.]_

A hobbyist averaging 5-10% failures is considered typical and healthy; 10-20% usually points to a specific tuning or hardware issue (bed leveling, first-layer adhesion, or a worn nozzle) worth fixing rather than accepting as normal. Industrial SLS machines run under 1% failure, while budget-tier FDM printers can fail as often as 1 in 5 prints even in capable hands, largely due to the mechanical simplicity and lower tolerances of the hardware itself.

## Two Worked Cost Breakdowns

**Small print — 45g PLA, 5.5-hour print, 8% failure rate, $0.16/kWh electricity**
| Component | Calculation | Cost |
| --- | --- | --- |
| Raw material | 45g ÷ 1000 × $18/kg | $0.81 |
| Failure-adjusted material | $0.81 ÷ (1 - 0.08) | $0.88 |
| Electricity | 120W × 5.5h ÷ 1000 × $0.16/kWh | $0.106 |
| Total |  | $0.99 |

**Large print — 320g PETG, 18-hour print, 12% failure rate, $0.16/kWh electricity**
| Component | Calculation | Cost |
| --- | --- | --- |
| Raw material | 320g ÷ 1000 × $19/kg | $6.08 |
| Failure-adjusted material | $6.08 ÷ (1 - 0.12) | $6.91 |
| Electricity | 140W × 18h ÷ 1000 × $0.16/kWh | $0.40 |
| Total |  | $7.31 |

_[Figure: Where the $7.31 large-print cost goes — On long prints, failure-rate waste can matter more to total cost than most people expect.]_

Notice how the failure-rate adjustment moves the numbers: on the large print, the 12% failure rate adds $0.83 on top of the raw material cost — more than double the electricity cost for that same print. On long, multi-hour prints especially, failure rate can matter more to total cost than the electricity draw most people worry about first.

## PLA vs. PETG vs. ABS: More Than Just Price

- PLA is the cheapest and easiest material to print reliably, with the lowest failure rates for beginners since it tolerates a wider range of temperatures and doesn't warp as aggressively — but it has the lowest heat resistance and can deform in a hot car or direct sunlight.
- PETG now often costs about the same as PLA per kilogram while offering better impact resistance, layer adhesion, and heat tolerance — it has become the default upgrade choice for functional parts rather than purely decorative prints.
- ABS and ASA cost roughly the same range as PETG but need an enclosed printer and good ventilation (ABS fumes are more of a concern than PLA or PETG), and they're more prone to warping on large flat prints without a heated enclosure — which pushes their real-world failure rate higher unless the printer is properly set up for them.

## A Closer Look at Electricity Cost

Printer wattage isn't constant throughout a print — it spikes during initial bed and nozzle heating (sometimes 250-350W briefly on a printer with a large heated bed) and then settles to a lower steady-state draw once temperatures stabilize, typically 80-150W depending on bed size, ambient temperature, and whether the enclosure (if any) is actively heated. For cost estimation purposes, using an average wattage figure across the whole print is accurate enough — the brief heating spike represents a small fraction of total print time on any print longer than about 30 minutes.

Electricity rates vary substantially by region and even by time of day on variable-rate plans, so the $0.16/kWh figure used in the worked examples above is a reasonable US-average planning number, not a universal constant — checking your own utility rate (usually printed on a recent bill, or listed in your provider's online account) will make any cost estimate meaningfully more accurate for your specific situation.

## Common Cost-Estimation Mistakes

- Comparing filament only by spool price instead of cost-per-gram. A $25 spool of one material and a $19 spool of another aren't comparable unless you also know the spool weight (most are 1kg, but some specialty filaments come in 500g or 750g spools).
- Ignoring electricity cost entirely. On short prints it's negligible, but on an 18+ hour print at 140W it adds up — and multiplies quickly if you're running several printers or a print farm.
- Budgeting as if every print succeeds. At even a modest 10% failure rate, roughly 1 in 10 prints needs to be reprinted from scratch, and that wasted material and electricity should be priced into your average cost per successful part.
- Not accounting for support material and purge waste, which can add 10-30% more filament usage on complex geometries beyond the visible part's own volume.
- Using a national-average electricity rate instead of your own utility rate, which can differ by 2x or more between regions.

## Frequently Asked Questions

**How much does it cost to 3D print something?**

It depends on material used, price per kg, print duration, printer wattage, electricity rate, and failure rate. A small 45-gram PLA print might cost under $1 total, while a large multi-hour PETG print can run $7 or more once electricity and failure-rate waste are included.

**Is PLA or PETG cheaper?**

They are now often price-competitive, with PETG sometimes matching or slightly exceeding PLA per kilogram. PLA typically has a lower failure rate for beginners since it prints more forgivingly, which can make its effective cost per successful print even lower.

**How much electricity does a 3D printer use?**

A typical FDM printer draws roughly 80-150 watts once temperatures stabilize (with brief spikes to 250-350W during initial heating). Over an 18-hour print averaging 140W, that's about 2.52 kWh — at $0.16/kWh, roughly $0.40 in electricity for that single print.

**What is a normal failure rate for 3D printing?**

5-10% is typical and healthy for an experienced hobbyist with a well-maintained printer. 10-20% usually indicates a specific fixable issue like bed leveling or first-layer adhesion. Beginners in their first 6 months often see 15-25% until they dial in their settings.

**Why does failure rate affect my average cost per print?**

If 1 in 10 prints fails outright, the material wasted on those failures still cost money — spreading that cost across your successful prints (dividing by 1 minus the failure rate) gives a more honest average cost per finished part.

**Do I need to budget for support material separately?**

For complex geometries with overhangs, yes — support structures and purge waste can add 10-30% more filament usage beyond the visible part itself, on top of the failure-rate adjustment.

**Why does ABS have a higher real-world failure rate than PLA?**

ABS is more prone to warping on large flat prints without a heated enclosure, since it cools and contracts more than PLA during printing. This mechanical sensitivity raises its real-world failure rate for printers not properly set up with an enclosure.

**Should I use national-average electricity rates for my cost estimate?**

It's better to check your own utility bill or online account for your actual per-kWh rate. Electricity prices vary substantially by region and can differ by 2x or more between areas, which meaningfully changes cost estimates for long prints.

**Do resin printers have the same cost structure as filament printers?**

The general formula (material + electricity + failure-rate waste) applies to both, but resin is priced and consumed differently — by milliliter rather than by gram — and resin printers typically use less electricity per print but require separate curing and cleaning steps with their own consumable costs.

## Final Summary

Total print cost = failure-adjusted material cost + electricity cost. Material price per kg is only one input — failure rate and print duration both meaningfully change the real cost of a print, especially on long jobs where electricity and wasted attempts can rival or exceed the raw material cost.
