About These 3D Printing Calculators
3D printing cost estimation sits at the intersection of material science and practical workshop economics. The true cost of a printed part is not just the filament or resin consumed - it includes electricity, machine depreciation, labor, and for resin prints, post-processing consumables like IPA and nitrile gloves. Understanding these cost components is essential whether you are printing for a hobby, running a small business, or evaluating whether 3D printing is more economical than traditional manufacturing for a specific part.
This collection of calculators covers both FDM (fused deposition modeling) filament printing and SLA/MSLA resin printing. The cost calculators break down per-part expenses into their individual components so you can see exactly where your money goes. The material comparison tools help you choose between PLA, PETG, ABS, Nylon, and various resin types based on real cost data rather than just spool prices. The FDM vs resin comparison provides an honest apples-to-apples analysis for makers who have access to both technologies.
All calculations run entirely in your browser with no data sent to any server. The material properties, densities, and default pricing are based on widely available consumer filaments and resins as of mid-2026. Adjust the prices to match your actual purchased costs for the most accurate per-part estimates.
