# VFA
|
||||
|
||||
Vertical Fine Artifacts (VFA) are small artifacts that can occur on the surface of a 3D print, particularly in areas where there are sharp corners or changes in direction. These artifacts can be caused by a variety of factors, including mechanical vibrations, resonance, and other factors that can affect the quality of the print.
|
||||
Vertical Fine Artifacts (VFA) are small surface imperfections that appear on vertical walls, especially near sharp corners or sudden directional changes. These artifacts are typically caused by mechanical vibrations, motor resonance, or rapid directional shifts that impact print quality.
|
||||
|
||||
Because of the nature of these artifacts the methods to reduce them can be mechanical such as changing motors, belts and pulleys or with advanced calibrations such as [Jerk/Junction Deviation](cornering-calib) corrections or [Input Shaping](input-shaping-calib).
|
||||
- **Mechanical adjustments**, such as tuning or replacing motors, belts, or pulleys.
|
||||
- **MMR (Motor Resonance Rippling)** is a common subtype of VFA caused by stepper motors vibrating at resonant frequencies, leading to periodic ripples on the surface.
|
||||
- **[Jerk/Junction Deviation](cornering-calib)** settings can also contribute to VFA, as they control how the printer handles rapid changes in direction.
|
||||
- **[Input Shaping](input-shaping-calib)** can help mitigate VFA by reducing vibrations during printing.
|
||||
|
||||
## VFA Test
|
||||
|
||||
OrcaSlicer's VFA test is used to identify the print speed that minimizes ringing artifacts. It prints a tower with walls at key angles while gradually increasing the print speed. The goal is to find the speed at which VFA artifacts are least visible, revealing the optimal range for clean surfaces.
|
||||
The VFA Speed Test in OrcaSlicer helps identify which print speeds trigger MRR artifacts. It prints a vertical tower with walls at various angles while progressively increasing the print speed.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
After printing, inspect the tower for MRR artifacts. Look for speeds where the surface becomes visibly smoother or rougher. This allows you to pinpoint problematic speed ranges.
|
||||
|
||||
You can then configure the **Resonance Avoidance Speed Range** in the printer profile to skip speeds that cause visible artifacts.

||||

||||
You will be promted to enter the settings for the test: start volumetric speed, end volumentric speed, and step. It is recommended to use the default values (5mm³/s start, 20mm³/s end, with a step of 0.5), unless you already have an idea of the lower or upper limit for your filament.

Select "OK", slice the plate, and send it to the printer.
|

Once printed, take note of where the layers begin to fail and where the quality begins to suffer. Pay attention to changes from matte to shiny as well.
|
||||
|
||||
|
||||
|
||||
|
||||
Using calipers or a ruler, measure the height of the print at that point. Use the following calculation to determine the correct max flow value: `start + (height-measured * step)` . For example in the photo below, and using the default setting values, the print quality began to suffer at 19mm measured, so the calculation would be: `5 + (19 * 0.5)` , or `13mm³/s` using the default values. Enter your number into the "Max volumetric speed" value in the filament settings.

||||
|
||||

You can also return to OrcaSlicer in the "Preview" tab, make sure the color scheme "flow" is selected. Scroll down to the layer height that you measured, and click on the toolhead slider. This will indicate the max flow level for your filament.
