3D Printing Cost Guide: What Affects Price?

Understanding how 3D printing costs are calculated helps you optimize your designs for manufacturing and keep your project within budget.

Pricing factors at a glance

| Cost Factor | Impact | How to Optimize | |---|---|---| | Part volume | High — more material = higher cost | Hollow parts, reduce wall thickness (within tolerance limits) | | Material choice | High — engineering materials cost 2-4x more | Use PLA for display, PETG/ABS for functional (see materials guide) | | Technology | Medium — SLA/DLP cost more than FDM | Use FDM for parts >50mm unless you need resin-level detail | | Infill density | Medium — 100% infill uses 3-5x more material than 20% | 20% for display, 50% for moderate load, 100% only for max strength | | Support structures | Medium — supports use material and add removal time | Orient part to minimize supports; avoid overhangs >45° | | Post-processing | Medium — sanding/painting adds 15-40% | Specify finish requirements upfront; batch orders save on finishing time | | Quantity | Positive — bulk orders reduce per-unit cost | Volume discounts applied automatically in our Shop |

How is the base price calculated?

The base price of a 3D printed part is determined by the volume of material used and the machine time required. Larger parts naturally cost more due to material consumption, but machine time is equally critical. A part that requires dense internal structures (infill) or complex support scaffolding will take longer to print, increasing the cost.

Which technology is the most cost-effective?

Fused Deposition Modeling (FDM) is generally the most cost-effective technology for large, structural parts and basic prototypes. SLA and DLP resin printing tend to have a higher base cost due to the premium photopolymer materials and the intensive post-processing required (washing and UV curing). However, for small, highly detailed parts, resin can sometimes be more economical than high-resolution FDM.

How do finishes affect the price?

Raw, un-sanded parts straight off the printer are the cheapest option. Post-processing requires skilled manual labor. Requesting sanded surfaces, primer application, or full-color painting will add 15% to 40% to the unit cost, depending on the complexity of the geometry and the required finish level. See our functional vs display parts guide for guidance on when finishing is worth the cost.

Are there discounts for bulk orders?

Absolutely. While 3D printing doesn't have the massive economies of scale of injection molding, ordering in bulk reduces the per-unit setup time, machine handling, and post-processing overhead. At EOD Cube, we apply automatic volume discounts when you order multiples of a part, which you can see live in our Shop catalog.
