3D Printing Cost Calculator: How Much Does It Cost? [2026]
Updated March 2026 · 10 min read
Using a 3D printing cost calculator — even a rough mental model — before requesting a quote can save you hours of back-and-forth and prevent sticker shock. The cost of 3D printing a part depends on four variables: the technology you choose, the material, the volume and weight of the part, and any post-processing required. This guide walks through each factor so you can estimate your cost before you ever send a file to a shop.
How 3D Printing Services Calculate Your Quote
Most service bureaus use one of three pricing models:
- Per-gram pricing (FDM) — Common for FDM. Shops charge $0.10–$0.30 per gram of material used, plus a per-part setup fee of $3–$10. A 100g part costs roughly $13–$40 before finishing.
- Per-volume pricing (SLS, metal) — SLS shops often charge $0.50–$1.50 per cm³ of part volume. This reflects the laser time and powder usage more accurately than weight alone.
- Per-hour machine time (resin) — Resin shops sometimes charge by print time plus material: $2–$8/hour of machine time plus $0.15–$0.50/gram of resin consumed.
Understanding which model your shop uses helps you optimize your design. For per-gram FDM pricing, reducing infill density saves money. For per-volume SLS pricing, hollowing out non-structural sections cuts cost significantly.
Step-by-Step Cost Estimation
Here's how to build a rough estimate before you have a quote:
Step 1: Choose Your Technology
Technology is the biggest cost lever. A quick guide:
- FDM — Cheapest. Use for functional parts, jigs, and housings where surface finish isn't critical.
- Resin (SLA/DLP) — Mid-range. Use when detail and smooth surfaces matter more than strength.
- SLS (Nylon) — Higher cost, highest functional quality for polymer parts. No support marks.
- Metal (DMLS/SLM) — Most expensive. Only when you genuinely need metal properties.
Step 2: Estimate Your Part Weight or Volume
Slice your STL in a free slicer (PrusaSlicer, Bambu Studio, Chitubox) even if you're not printing yourself. It will tell you the exact material weight at your chosen infill. This is the single most accurate input to any cost estimate.
| Part Size | Approx. Weight (PLA, 20% infill) | Estimated FDM Cost |
|---|---|---|
| 50×50×30mm | ~15–25g | $5–$15 |
| 100×80×50mm | ~50–80g | $12–$28 |
| 150×120×80mm | ~120–180g | $20–$50 |
| 250×200×100mm | ~300–500g | $40–$100+ |
Estimates at $0.15–0.20/g + $5 setup fee. Actual costs vary by shop and geometry.
Step 3: Add Material Premium (if applicable)
PLA is the baseline. Apply these multipliers for specialty materials:
- PETG: +10–20%
- ABS: +15–25%
- Nylon (PA12): +30–60%
- Carbon fiber composite: +50–100%
- TPU/flexible: +20–40%
- Standard resin: +100–200% over FDM equivalent
- Engineering resin (ABS-like, tough): +200–400%
Step 4: Factor In Post-Processing
Raw prints are the baseline. Add these to your estimate for any requested finishing:
- Support removal + cleanup: Usually included. Ask if there's a charge for complex geometries.
- Sanding (rough → smooth): +$5–$20 per part depending on size.
- Priming + painting: +$15–$50 per part.
- Vapor smoothing (ABS): +$10–$30 per part.
- Dyeing (SLS nylon): +$5–$15 per part.
- Threaded inserts installed: +$2–$5 per insert.
Step 5: Apply Rush Premium (if needed)
Same-day or next-day turnaround adds 50–100% to the base cost. Standard 2–5 day turnaround has no premium. If your deadline is flexible, standard is almost always the right call.
Real-World Cost Examples
Let's run the calculator on three common small business scenarios:
Example 1: Custom product display stand
150×80×60mm, FDM PLA, raw finish, standard turnaround
Estimated cost: $18–$35
Example 2: Functional prototype housing
100×80×40mm, FDM PETG, threaded inserts, sanded finish, 5-day turnaround
Estimated cost: $35–$65
Example 3: Visual prototype for client pitch
80×60×30mm, resin SLA, primed + painted, standard turnaround
Estimated cost: $60–$110
How to Reduce Your 3D Printing Costs
- Lower your infill density. Most functional parts work fine at 15–20% infill. Dropping from 50% to 20% can cut material cost by 30–40%.
- Reduce wall thickness where structurally possible. 2 perimeters (1.6mm) instead of 4 (3.2mm) cuts material significantly on large hollow parts.
- Get 3 quotes. Pricing between shops varies 2–5× for identical parts. Our directory makes this fast.
- Batch your orders. Printing 10 of the same part at once is never 10× the cost. Most shops discount 20–30% at quantity 10+.
- Choose standard colors. Black and white are almost always loaded. Specialty colors sometimes require a spool swap fee.

Frequently Asked Questions
How much does 3D printing cost per gram?
FDM printing at most service bureaus runs $0.10–$0.30 per gram of material, plus a setup fee of $3–$10 per part. Resin and SLS pricing is structured differently — by volume or machine time — and runs higher.
Is there a free 3D printing cost calculator I can use?
The most accurate "calculator" is slicing your STL in a free tool like PrusaSlicer or Bambu Studio. It gives you exact weight and print time, which you can then multiply by your shop's per-gram or per-hour rate. Many online services (Craftcloud, Treatstock) also offer instant quote tools.
Why does 3D printing cost so much at some shops?
Labor (setup, support removal, post-processing), machine depreciation, and overhead vary widely between shops. A shop in a high-cost city with professional finishing services will charge more than a one-person FDM shop. Get multiple quotes and compare what's included in the price.
How can I reduce my 3D printing costs?
Lower infill density, reduce wall count where structurally acceptable, batch orders, choose standard colors, and get at least 3 quotes. For repeat orders, negotiate volume pricing directly with your shop.
Does 3D printing get cheaper for larger quantities?
Yes. Most shops offer 10–30% volume discounts for batches of 10+ identical parts. SLS printing drops significantly in per-part cost at volume because the powder bed can be packed with multiple parts, maximizing the efficiency of each build.
