Big Ironing Test

Big Ironing Matrix Test (10%–50% Flow & 20–100 mm/s)

Achieve a flawless, glassy top layer with ZERO setup!

Stop guessing your ironing settings or wasting hours configuring modifiers. This is a comprehensive, all-in-one calibration matrix designed to help you find the absolute perfect sweet spot for your specific filament and 3D printer.

With an extensive grid of 81 unique test combinations, you can analyze the interaction between ironing speed and flow rate at a single glance.

 True Plug & Play 

No tedious manual setup required. Download the provided .3mf project file. It already contains all 81 individual modifier zones pre-configured with the exact speed and flow values matching the grid. Just slice, print, and find your perfect settings!

What you get:

• Massive Test Range: From 10% to 50% flow rate (y-axis) and 20 mm/s to 100 mm/s speed (x-axis).
• Embossed Legends: Clean text integrated directly into the model so you can easily identify the exact settings after printing.
• Material & Time Efficient: Optimized thickness ensures low filament consumption and a quick print time.
• Immediate Visual Feedback: Easily spot underextrusion, overextrusion, rough spots, or that perfect mirror-smooth finish.

How to Use It:

1. Download & Open: Open the .3mf project file.
2. Select Filament: Choose your filament profile.
3. Slice & Print: Simply hit print! The slicer will automatically apply the different speeds and flows to each square.
4. Inspect & Select: Once finished, hold the print against the light. Find the square with the smoothest, most uniform surface, and copy those exact numbers into your main filament profile!

What to Look For:

• Too Little Flow (<): Rough texture, visible gaps, or original layer lines still showing through.
• Too Much Flow (>): Rough ridges, plastic scraping, plowing marks, or filament buildup at the edges.
• Perfect Balance (🎯): A completely smooth, flat, uniform, and glossy finish with no visible lines.

Perfect for testing:

• Ironing Flow Rate (%)
• Ironing Speed (mm/s)
• Fine-tuning new filament brands (PLA, PETG, ABS, ASA, etc.)

Suitable for:

• Beginners wanting a hassle-free calibration tool.
• Advanced users looking for maximum print perfection.
• Anyone who hates visible layer lines on top surfaces!
