🔍 Understanding the “Per Gram” Question: More Than Just Weight

When someone asks, “How much does 3D print cost per gram?” it sounds straightforward, right? But the truth is, weight is just one piece of the puzzle. Let’s unpack why:

  • Material cost is easy to quantify per gram, especially for filaments and resins, making it a handy baseline.
  • However, printing time, machine wear, electricity, and labor don’t scale linearly with weight. A tiny, complex print might cost more per gram than a large, simple one.
  • Some printers and materials require support structures or infills, which add weight but don’t always add value to the final object.
  • Post-processing (sanding, curing, painting) can add significant time and cost unrelated to weight.

What You Should Consider Alongside Weight

  • Volume and design complexity
  • Print speed and layer height
  • Printer type (FDM, SLA, SLS, etc.)
  • Material type and quality
  • Failure rates and waste

So, while “per gram” is a useful metric, it’s best paired with other cost factors to get the full picture.

💰 The True Cost of 3D Printing: Beyond the Filament Spool

Let’s bust the myth that 3D printing cost is just about filament price. Here’s what really goes into the total cost:

Cost Component Description Typical Impact on Cost
Material Filament, resin, powder, or metal powder 30-50%
Printer Depreciation Amortized cost of printer over its lifespan 10-20%
Electricity Power consumption during printing and post-processing 1-5%
Labor Time spent preparing, monitoring, and finishing prints 20-30%
Post-Processing Cleaning, curing, sanding, painting 5-15%
Failed Prints/Waste Material and time lost due to errors Variable; can be significant
Software & Licensing CAD software, slicers, and cloud services Variable
Maintenance & Repairs Replacement parts, nozzle changes, calibration Small but recurring

Pro tip: As Josef from Prusa3D points out, “Material and manpower are the most expensive aspects. Energy costs are almost negligible.” (source)

🧮 Breaking Down the Numbers: Calculating Your Own Cost Per Gram

Ready to crunch some numbers? Here’s a step-by-step formula to estimate your 3D print cost per gram, inspired by the detailed approach from Prusa3D:

Step 1: Calculate Material Cost

[
\text{Material Cost} = \frac{\text{Filament Price per Spool}}{\text{Spool Weight (grams)}} \times \text{Model Weight (grams)}
]

Example: A 1kg spool of PLA at $25, printing a 50g model:

[
25 / 1000 \times 50 = 1.25 \text{ USD}
]

Step 2: Calculate Electricity Cost

[
\text{Electricity Cost} = \text{Printer Power (kW)} \times \text{Print Time (hours)} \times \text{Electricity Rate (USD/kWh)}
]

Example: Printer uses 0.1 kW, print time 2 hours, electricity rate $0.12/kWh:

[
0.1 \times 2 \times 0.12 = 0.024 \text{ USD}
]

Step 3: Calculate Printer Depreciation Cost

[
\text{Depreciation Cost} = \frac{\text{Printer Cost}}{\text{Expected Printer Lifespan (hours)}} \times \text{Print Time (hours)}
]

Example: $600 printer, lifespan 2000 hours, print time 2 hours:

[
600 / 2000 \times 2 = 0.60 \text{ USD}
]

Step 4: Add Labor Cost

Estimate your hourly labor rate and multiply by time spent preparing and post-processing.

Example: $15/hour, 30 minutes total:

[
15 \times 0.5 = 7.50 \text{ USD}
]

Step 5: Add Post-Processing Consumables (if any)

Include costs of resin wash, sandpaper, paint, etc.
