When should you use this tool?
Use it when a print takes too long or consumes too much material and you want to identify the changes with the largest realistic impact.

Print Time & Filament Optimizer
Review your slicer profile for the biggest realistic savings opportunities without fake percentage claims. Layer height, line width, infill, travel, Z-hop, flow limits and multi-material are evaluated separately.

How to optimize safely
Do not change everything at once. Start with one high-priority item, slice the same model again and compare time, material and preview. Move to the next item only if quality remains stable.
For multi-material, the order matters: calibrate flush/purge first, then use safe flush-into-geometry options, then optimize the tower. Reducing too aggressively can create color contamination, unstable restart flow or poor material separation.
Tool guide
Print Time & Filament Optimizer: when and how should you use it?
A useful result starts with the right question. These notes explain what the tool is designed for, how to interpret its output and where a calculation is intentionally only an approximation.
How to use it well
Enter the current profile values, read the priorities, change one high-impact item and slice the same model again. Compare time, material and preview before making the next change.
Limits & important notes
The optimizer does not blindly target the shortest possible print. Part function, surface requirements and material limits remain more important than the lowest time estimate.
Frequently asked questions
Why not simply minimize every setting?
Many settings affect strength, surfaces and reliability. The optimizer prioritizes changes that often deliver meaningful savings without blindly pushing critical parameters to extremes.
Are fewer walls and less infill always the best savings?
No. Orientation, layer height, travel strategy or fewer material changes can have a larger effect. Functional regions are often better optimized locally than weakened everywhere.
Does it help with multi-color prints?
Yes. Color changes, purge volume, prime tower and flush-into-infill/support become important. Use the Multi-Color Waste Calculator when you need a dedicated waste estimate.
Should I copy the suggested settings directly?
Treat them as a test priority. Printer, material, geometry and quality target determine how far each setting can safely be changed.
These tools provide guidance and calculations from your inputs. Safety-critical, electrical or highly loaded parts require additional verification.
