30 minutesReview STL dimensions, estimate print volume, and calculate filament weight needed for the project.
Field context
This workflow is part of 15 niche fields
3D printing project workflow with model scaling, filament usage estimates, print time calculations, slicer settings, support planning, and post-processing.
Review STL dimensions, estimate print volume, and calculate filament weight needed for the project.
Set layer height, print speed, and infill density. Estimate print duration from model dimensions and speed settings.
Compute total material cost, electricity, and machine depreciation to determine project cost or selling price.
Start the print, monitor first layer adhesion, and track actual print time against estimates.
Remove supports, sand, and finish the print. Document actual costs and time for future project estimates.
Estimate grams of filament required from model volume and infill. · Verify material cost from estimated filament weight. · Compare estimated vs actual filament usage for calibration.
Calculate material weight at different infill percentages.
Estimate print duration from model height, layer height, and speed. · Compare estimated vs actual print time during monitoring.
Determine optimal layer height for nozzle size and quality target.
Calculate total print cost including material, electricity, and time. · Record actual costs for project documentation.
Typical material costs for common 3D printing filaments.
| Material | Cost/kg | Cost/gram | Best For |
|---|---|---|---|
| PLA | $18–25 | $0.018–0.025 | General purpose, prototypes |
| PETG | $22–30 | $0.022–0.030 | Functional parts, outdoor use |
| ABS | $20–28 | $0.020–0.028 | Heat-resistant parts |
| TPU/Flexible | $30–45 | $0.030–0.045 | Gaskets, phone cases |
Moisture in PLA/PETG causes stringing and weak layers. Store filament in sealed bags with desiccant; dry at 45–55°C for 4+ hours if needed.
Thermal runaway and filament blob failures can cause fires. Use a smoke detector near your printer and remote monitoring camera.
Accurate extrusion calibration saves 10–15% filament waste and improves dimensional accuracy across all prints.
Printing multiple copies in one job saves heating time and bed leveling — amortize setup cost across the batch.
