3D Printing Pricing Strategies: How to Price Jobs Without Losing Money

Pricing is where most 3D print shops get it wrong. Not because they're bad at math, but because they're using the wrong model — or not accounting for all their costs.

The right pricing strategy depends on what you're printing, who you're printing for, and how your shop operates. Here's how to think about it.

The Four Pricing Models

1. Per Gram

How it works: Charge a flat rate per gram of material used (e.g., $0.50/g for PLA, $2.00/g for Nylon).

Pros: Simple, easy for customers to understand, easy to quote.

Cons: Ignores machine time entirely. A tall, thin part that takes 14 hours but uses 30g of material is wildly underpriced at $0.50/g. A dense, fast part is overpriced.

Best for: Quick-turn consumer parts, simple geometries, shops that want zero-friction quoting.

Watch out: If your average job takes more than 4 hours, per-gram pricing is probably leaving money on the table.

2. Per Hour (Machine Time)

How it works: Charge based on estimated print time (e.g., $5/hr for FDM, $15/hr for SLA).

Pros: Directly tied to your biggest cost (machine occupancy). Long jobs pay appropriately.

Cons: Customers can't estimate cost themselves. Time estimates vary by slicer settings.

Best for: Production runs, large-format prints, shops with high utilization.

3. Per Part (Fixed Price)

How it works: Quote a fixed price per part, usually calculated from time + material + labor + margin.

Pros: Clean for customers, great for repeat orders, easy to batch.

Cons: Requires accurate cost estimation upfront. Get it wrong and you're locked in.

Best for: Repeat production, catalog items, batch orders. Use the cost estimator to build your per-part price.

4. Project-Based

How it works: Quote the entire project as a package — design consultation, printing, post-processing, assembly, shipping.

Pros: Captures the full value of your work (not just machine time). Customers get one number.

Cons: Hardest to estimate accurately. Scope creep risk.

Best for: Complex projects, design-to-delivery services, architectural models, custom fabrication.

Know Your True Cost Per Hour

Before you can price anything, you need to know what it costs to run your machines. Here's the breakdown:

Machine depreciation: Purchase price ÷ expected useful hours. A $3,000 printer running 10,000 hours over its life = $0.30/hr.

Electricity: Check your printer's wattage × your local rate. Most FDM printers run $0.03-0.10/hr. Heated enclosures and large-format machines run higher.

Rent allocation: Your monthly rent ÷ operating hours ÷ number of machines. If you're paying $2,000/month for a space with 4 machines running 8 hours/day, that's roughly $2.60/hr per machine.

Maintenance and consumables: Nozzles, build surfaces, resin tanks, filters, replacement parts. Budget 5-10% of machine cost annually.

Labor: Your time for setup, monitoring, post-processing. Even if you're the owner, your time has a cost.

Add it all up. For most FDM shops, true machine cost lands between $3-8/hour before labor and material. For SLA/SLS, it's $8-20/hr. This is your floor — never quote below it.

Margin Targets

| Service Type | Target Gross Margin | |---|---| | Simple FDM parts | 40-60% | | SLA/resin parts | 35-50% | | Production runs (50+ parts) | 30-45% | | Post-processing heavy | 35-50% | | Design + print | 50-65% | | Rush jobs | 50-75% |

If you're consistently below 30% margin, you're either underpricing or your cost structure needs work.

Volume Pricing Without Giving Away Margin

Customers expect a discount for ordering 100 parts instead of 1. That's fair — your setup cost is amortized and you can optimize nesting. But don't give away all the savings.

Rule of thumb: Pass 40-60% of the batch savings to the customer, keep the rest as improved margin.

Use the batch vs. single calculator to see the real difference. If a single part costs you $12 and a batch of 50 costs $7/part, don't price the batch at $7 — price it at $9-10. The customer gets a deal, you get a better margin than the single.

Pricing Psychology

A few things that help:

• Always quote in writing. Verbal quotes lead to disagreements.
• Show line items. Material, print time, post-processing, setup. Transparency builds trust.
• Offer good/better/best. Standard finish vs. premium finish vs. painted. Let the customer choose the price point.
• Rush premiums are expected. 50-100% markup for rush is standard in manufacturing. Don't feel bad about it.

Track Everything

The single most important thing you can do for pricing: track actual costs against quoted costs for every job. After 50 jobs, your data will show you exactly where you're making money and where you're not.

3DPrintOps tracks quotes, jobs, and margins automatically — so you're not rebuilding this in a spreadsheet every month. Pair it with the cost estimator and post-processing calculator to quote with confidence.
