How to Price 3D Printed Parts for Sale (Material + Time + Markup Calculator)

Underpricing is the number one killer of 3D printing businesses. New sellers look at the filament cost, add a small margin, and wonder why they are working for less than minimum wage after factoring in their time, electricity, machine wear, and failed prints.

Pricing 3D printed parts correctly requires understanding every cost that goes into producing and delivering a part. This guide breaks down the complete cost structure and gives you a practical formula you can use to price any part profitably.

The Complete Cost Formula

Here is the formula that covers everything:

Selling Price = (Material + Electricity + Machine Depreciation + Labor + Failed Print Allowance + Packaging + Shipping + Platform Fees + Overhead) x Profit Multiplier

That looks complicated, but each component is straightforward once you know how to calculate it. Let us work through each one.

Material Cost

This is what most people start and stop with. It is actually the smallest component for most prints.

Calculating Filament Cost Per Print

Your slicer tells you exactly how much filament each print uses in grams. To get the cost:

Material cost = (Print weight in grams / 1000) x Price per kilogram

A standard roll of PLA is 1 kilogram and costs $18 to $25. PETG runs $20 to $28. ASA is $25 to $35. Specialty filaments (carbon fiber, nylon, TPU) range from $30 to $60 per kilogram.

Example: A part weighs 45 grams. You are using PLA at $20 per kilogram. Material cost = (45 / 1000) x $20 = $0.90

Do not forget supports and waste. If your print uses supports, the actual material consumed is higher than the part weight. Add 10 to 30 percent depending on support density. Purge towers for multi-color prints can add 20 to 50 grams per color change.

Other Consumables

• Build plate adhesive (glue stick, hairspray): roughly $0.02 to $0.05 per print
• Nozzle wear: A brass nozzle costs $2 and lasts roughly 500 to 1,000 print hours, so about $0.002 to $0.004 per hour. Hardened steel nozzles cost $15 but last 5,000+ hours.
• PTFE tube replacement: $3 to $5 every 500 to 1,000 hours
• Replacement build plates: $15 to $40 every 6 to 12 months with heavy use

These add up to roughly $0.01 to $0.05 per print hour. Small per part, but worth tracking at volume.

Electricity Cost

Calculating Power Cost

A typical FDM printer draws 200 to 500 watts during printing. The actual draw depends on heated bed size, enclosure heating, and speed.

Electricity cost = Printer wattage (kW) x Print time (hours) x Electricity rate ($/kWh)

The average US electricity rate is $0.16 per kWh in 2026, but rates vary from $0.10 in the Southeast to $0.35+ in California and Hawaii.

Example: Your printer draws 350 watts. The print takes 4 hours. Your electricity costs $0.16 per kWh. Electricity cost = 0.35 x 4 x $0.16 = $0.22

For a 4-hour print, electricity is minimal. For a 24-hour print, it adds up to $1.34. Not huge, but real.

Measuring Actual Draw

Plug-in power meters like the Kill-A-Watt ($25) measure actual power consumption. Run your printer through a typical job and record the reading. Different filaments and settings change the draw: ABS with a heated bed at 100 degrees Celsius draws significantly more than PLA with a bed at 55 degrees.

Machine Depreciation

Your printer is a depreciating asset. Every print hour brings it closer to end of life or major refurbishment. You need to recoup the purchase price over the printer's useful life.

Calculating Hourly Depreciation

Depreciation per hour = Purchase price / Estimated useful print hours

A $400 printer with an estimated useful life of 5,000 print hours: Depreciation = $400 / 5,000 = $0.08 per print hour

A $1,000 printer with 10,000 hours of useful life: Depreciation = $1,000 / 10,000 = $0.10 per print hour

For a 4-hour print on the $400 printer: Depreciation cost = 4 x $0.08 = $0.32

This seems small, but it is essential for long-term sustainability. When your printer dies after 5,000 hours, you need to have earned enough to replace it.

What Counts as Useful Life?

A well-maintained FDM printer can run 5,000 to 15,000 print hours before needing major replacement parts (stepper motors, linear rails, mainboard). Budget printers tend toward the lower end. Premium printers toward the higher end.

Labor Cost

This is where most sellers drastically underprice. Your time has value. Every minute you spend on a print job is a minute you cannot spend on something else.

Direct Labor

Time spent directly on the job:

• Setup: Loading filament, cleaning the bed, slicing the model, starting the print. Typically 5 to 15 minutes.
• Monitoring: Checking the first few layers, occasional checks during printing. Average 5 to 10 minutes per job, more for long prints.
• Post-processing: Removing supports, sanding, painting, assembling. Anywhere from 5 minutes to 2+ hours depending on the part.
• Packing and shipping: Packaging the item, printing a label, dropping at the post office. 5 to 15 minutes.

Indirect Labor

Time spent on business operations:

• Customer communication: Answering questions, processing orders, handling returns
• Design work: Creating or modifying models for customers
• Photography: Taking and editing product photos
• Accounting: Tracking expenses, filing taxes, managing inventory

What Rate to Charge

Pay yourself at least a living wage. If your local market rate for skilled work is $25 to $50 per hour, that is your labor rate. Many 3D printing service bureaus charge $30 to $75 per hour for labor.

Example: A print job requires 15 minutes of setup, 10 minutes of post-processing, and 10 minutes of packing. Total: 35 minutes. At $30 per hour: Labor cost = (35/60) x $30 = $17.50

This is almost always the largest cost component. And it is the one most sellers ignore.

Failed Print Allowance

Not every print succeeds. A 95 percent success rate means 1 in 20 prints fails. You eat the material, electricity, and time on those failures. Build this into your pricing.

Calculating Failure Markup

Failure multiplier = 1 / Success rate

At a 95 percent success rate: 1 / 0.95 = 1.053 (multiply all costs by 1.053) At a 90 percent success rate: 1 / 0.90 = 1.111 At a 85 percent success rate: 1 / 0.85 = 1.176

If you are below 90 percent success rate, fix your process before worrying about pricing. Calibrate your printer, dial in your profiles, and use quality filament.

Packaging Cost

• Basic poly bag: $0.05 to $0.10
• Bubble wrap: $0.10 to $0.25
• Small box: $0.50 to $1.50
• Branded sticker or card: $0.10 to $0.30
• Tissue paper: $0.05 to $0.10

A typical small item ships in $0.50 to $1.00 of packaging materials. Larger or fragile items may require $2 to $5 in packaging.

Shipping Cost

Pass Through vs. Built In

You can charge the customer actual shipping cost (pass-through) or build shipping into your product price and offer "free shipping." The latter tends to increase conversion rates on marketplaces because buyers psychologically prefer a $25 item with free shipping over a $18 item with $7 shipping.

Typical Shipping Costs (US Domestic)

• USPS First Class (under 16 oz): $3.50 to $5.50
• USPS Priority Mail: $8 to $15
• USPS Priority Flat Rate Small Box: $10.20
• UPS/FedEx Ground: $8 to $15 for small packages

Use discounted shipping through Pirate Ship, Stamps.com, or your marketplace's built-in shipping labels.

Platform and Payment Fees

Every sales channel takes a cut:

• Etsy: 6.5% transaction fee + $0.20 listing fee + 3% payment processing + 15% offsite ads (if enrolled)
• Amazon Handmade: 15% referral fee
• Shopify: 2.9% + $0.30 payment processing + monthly plan ($39+)
• PayPal/Stripe: 2.9% + $0.30 per transaction

These fees apply to the total sale price including shipping. On a $25 item with $5 shipping, Etsy takes roughly $2.15 to $4.70 depending on ad enrollment.

Overhead

Fixed costs that do not change per print but must be recovered:

• Internet service (portion allocated to business): $10 to $30 per month
• Software subscriptions (CAD, slicer plugins, accounting): $0 to $50 per month
• Business insurance: $25 to $50 per month
• Business license: $2 to $10 per month
• Office/workspace costs (even if it is a room in your home): varies

Divide monthly overhead by monthly print volume to get per-unit overhead cost. If overhead is $100 per month and you sell 50 items, overhead per item is $2.00.

Profit Margin

After covering every cost above, you need profit. Profit is not your salary (that is in labor cost). Profit is what you reinvest in the business or retain as return on your investment.

A healthy profit margin for a 3D printing business is 20 to 40 percent on top of all costs. Some high-value custom work commands 50 percent or more. Commodity items might only support 15 to 20 percent.

Profit multiplier of 1.25 = 25% margin Profit multiplier of 1.40 = 40% margin

Putting It All Together: Example

Let us price a custom phone stand that takes 3 hours to print and 20 minutes of post-processing and packing.

Component	Calculation	Cost
Material (PLA, 62g)	62/1000 x $20	$1.24
Electricity	0.30 kW x 3 hr x $0.16	$0.14
Machine depreciation	3 hr x $0.08	$0.24
Labor (20 min)	20/60 x $30	$10.00
Subtotal		$11.62
Failed print allowance (5%)	x 1.053	$12.24
Packaging		$0.75
Platform fees (est. 12%)		$1.86
Overhead allocation		$2.00
Total cost		$16.85
Profit (30% margin)	x 1.30	$21.91

Selling price: approximately $22

If you had priced based on filament cost alone ($1.24) and added a 3x markup, you would have priced it at $3.72, losing money on every sale.

Value-Based Pricing Adjustments

The calculator gives you your floor, the minimum you should charge. But value-based pricing can push you higher:

• A custom replacement part for an expensive appliance is worth more than its production cost
• Rush orders command a 25 to 50 percent premium
• Design work (creating a model from a customer's sketch) should be charged separately at $30 to $75+ per hour
• Unique or exclusive designs have higher perceived value
• Functional parts that solve a real problem can be priced on the value of the solution

If a customer needs a $2 part to fix a $500 machine, pricing it at $15 to $25 is fair and the customer will happily pay.

Quick Reference Pricing Tiers

For quick estimates before running the full calculation:

Small decorative item (under 50g, minimal post-processing): $8 to $15 Medium functional part (50 to 150g, some finishing): $15 to $35 Large or complex item (150 to 500g, significant finishing): $35 to $80 Custom design work (includes CAD time): $50 to $200+ Multi-part assembly: $40 to $150+

These are starting points. Always run the full calculation for your specific costs and margins.

Conclusion

Pricing 3D printed parts correctly is the difference between a profitable business and an expensive hobby. The material is almost never the significant cost. Labor, machine time, failure allowance, platform fees, and overhead dominate the real cost of producing a part.

Use the formula in this guide to calculate your true cost for each product. Set your price above that cost with a healthy margin. Do not be afraid of prices that seem "high" compared to the filament cost. Your customers are paying for the convenience, customization, and quality that only you provide, not just the plastic.

Track your actual costs over time. As you get faster, reduce your failure rate, and buy filament in bulk, your costs will decrease and your margins will improve. But start by knowing your numbers. Every successful 3D printing business is built on accurate pricing.
