How is a 3D printing quote
actually calculated?

WOW3D auto quotes combine material cost, machine time, layer height, infill density, supports, and finishing. This page explains price and lead time in plain language—based on questions customers ask most.

Quick answer

A 3D printing quote adds material cost (filament or resin used), machine cost (print time × the hourly rate for the process) and options such as supports and post-processing. Lower layer heights (FDM 0.1 mm vs 0.2 mm) mean more layers and longer print time, and higher infill uses more material and time, so the price rises.

Print process

FDM, SLA, and DLP use different machine rates and materials, so the same model can quote differently.

Layer & infill

Finer layers and higher infill increase material use and print time—and therefore price.

Print time

Machine time is a core quote driver and can vary widely with layer height and geometry.

What drives a WOW3D auto quote

3D printing cost is not size alone. Upload a file and WOW3D calculates volume, surface area, dimensions, process, layer height, infill, and finishing in real time.

Material: scales with filament or resin usage
Machine time: print duration × process hourly rate
Options: supports, finishing, special requirements
Review adjustments: complex geometry, specialty materials, or deadline needs

Layer height vs print time

Lower layer heights need more layers, so print time goes up. For example FDM at 0.1 mm needs more layers and longer machine time than 0.2 mm—better surface detail, often a higher quote.

0.1 mm: detail first / 0.2 mm: standard / 0.3 mm: speed first

Frequently asked questions

How is a 3D printing quote calculated?

WOW3D auto quotes combine material cost, machine time, layer height, infill, supports, and finishing. Time formulas and cost lines differ for FDM vs SLA/DLP.

Why does a lower layer height cost more?

Lower layers mean more layers for the same height, so print time increases. FDM at 0.1 mm needs more layers and longer machine time than 0.2 mm.

What is the difference between 20% and 100% infill?

Infill is internal density. Higher infill uses more material and time—raising the quote—but can suit parts that need strength and durability.

Should I choose FDM, SLA, or DLP?

Functional prototypes and durable parts usually fit FDM; surface quality and fine detail favor SLA or DLP. The best process depends on the goal, even for the same shape.

Can the auto quote differ from the final price?

Most typical models quote quickly, but complex geometry, specialty materials, finishing, or file issues may need admin review and a revised quote.

Can I get a quote without a 3D model file?

Yes. Upload a product photo (JPG/PNG), generate an AI 3D model, then continue to auto quote. For tight dimensional or assembly tolerances, prefer STL or STEP.
