How it works

Effective plastic volume blends a shell baseline with the selected infill fraction. Flow is line width times layer height times print speed; dividing volume by flow gives base time, then fixed overhead multipliers produce a range.

  • Fifteen percent infill, 0.4 mm nozzle, and 50 mm/s are starting values.
  • A range communicates omitted motion and cooling time.

Worked example

A 50cm3 part at 15% infill
0.2mm layers, 50mm/s, a 0.4mm nozzle
Input
											Print volume cm3: 50
Layer height mm: 0.2
Print speed mm s: 50
Infill percent: 15
Output
												Estimated hours low: 1.5
Estimated hours high: 2.1
Effective volume cm3: 22.38
Line width mm: 0.48

When to use this

Print-farm queues, overnight planning, and pre-slicer job comparisons estimate duration.

Edge cases

  • Travel and acceleration make actual time longer than volume-only time.
  • Many shells can dominate time at low infill.
  • Changing nozzle width changes both assumed path area and flow.
