Workflow
Configure Slicer Settings
20 minutesSet layer height, print speed, and infill density. Estimate print duration from model dimensions and speed settings.
Calculate Print Cost
15 minutesCompute total material cost, electricity, and machine depreciation to determine project cost or selling price.
Execute Print and Monitor
1-8 hoursStart the print, monitor first layer adhesion, and track actual print time against estimates.
Post-Process and Evaluate
30-60 minutesRemove supports, sand, and finish the print. Document actual costs and time for future project estimates.

Filament Cost ReferenceTable
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 |
Print Time EstimationFormula
Approximate print time = (Model height ÷ Layer height) × (Perimeter length ÷ Print speed) + overhead.
Infill Density GuidelinesTable
Recommended infill percentages by application.
| Application | Infill % | Pattern |
|---|---|---|
| Display models | 5–10% | Gyroid or lightning |
| General functional | 15–25% | Gyroid or cubic |
| Load-bearing parts | 40–60% | Cubic or honeycomb |
| Mechanical components | 80–100% | Solid or 100% infill |
Dry Your Filament
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.
Never Leave First Print Unattended
Thermal runaway and filament blob failures can cause fires. Use a smoke detector near your printer and remote monitoring camera.
Calibrate E-Steps and Flow
Accurate extrusion calibration saves 10–15% filament waste and improves dimensional accuracy across all prints.
Batch Similar Prints
Printing multiple copies in one job saves heating time and bed leveling — amortize setup cost across the batch.
Safety Notes
- 3D printers operate at 200–260°C with moving parts — keep children and pets away during operation.
- Print in a ventilated area; ABS and some resin printers emit VOCs. Enclose ABS prints or use PLA/PETG indoors.
