### 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.
|
||||
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/[Juction Deviation](#junction-deviation) corrections or [Input Shaping](#input-shaping).

The Flow Ratio determines how much filament is extruded and plays a key role in achieving high-quality prints. A properly calibrated flow ratio ensures consistent layer adhesion and accurate dimensions. If the flow ratio is too low, under-extrusion may occur, leading to gaps, weak layers, and poor structural integrity. On the other hand, a flow ratio that is too high can cause over-extrusion, resulting in excess material, rough surfaces, and dimensional inaccuracies.

Nozzle temperature is one of the most important settings to calibrate for a successful print. The temperature of the nozzle affects the viscosity of the filament, which in turn affects how well it flows through the nozzle and adheres to the print bed. If the temperature is too low, the filament may not flow properly, leading to under-extrusion, poor layer adhesion and stringing. If the temperature is too high, the filament may degrade, over-extrude and produce stringing.

Temp tower is a straightforward test. The temp tower is a vertical tower with multiple blocks, each printed at a different temperature. Once the print is complete, we can examine each block of the tower and determine the optimal temperature for the filament. The optimal temperature is the one that produces the highest quality print with the least amount of issues, such as stringing, layer adhesion, warping (overhang), and bridging.

Unless printed in spiral vase mode, every layer needs to begin somewhere and end somewhere. That start and end of the extrusion is what results in what visually looks like a seam on the perimeters. This section contains options to control the visual appearance of a seam.
|
||||
|
||||
- **Seam Position**: Controls the placement of the seam.
|
||||
## Seam Position
|
||||
|
||||
1. **Aligned**: Will attempt to align the seam to a hidden internal facet of the model.
|

2. **Nearest**: Will place the seam at the nearest starting point compared to where the nozzle stopped printing in the previous layer.

|
||||
4. **Random**: Will randomize the placement of the seam between layers.
|
||||
Controlling the position of seams can help improve the appearance and strength of the final print.
|
||||
|
||||
Typically, aligned or back work the best, especially in combination with seam painting. However, as seams create weak points and slight surface "bulges" or "divots," random seam placement may be optimal for parts that need higher strength as that weak point is spread to different locations between layers (e.g., a pin meant to fit through a hole).

|
||||
|
||||
- **Staggered Inner Seams**: As the seam location forms a weak point in the print (it's a discontinuity in the extrusion process after all!), staggering the seam on the internal perimeters can help reduce stress points. This setting moves the start of the internal wall's seam around across layers as well as away from the external perimeter seam. This way, the internal and external seams don't all align at the same point and between them across layers, distributing those weak points further away from the seam location, hence making the part stronger. It can also help improve the water tightness of your model.
|
||||
### Aligned
|
||||
|
||||
- **Seam Gap**: Controls the gap in mm or as a percentage of the nozzle size between the two ends of a loop starting and ending with a seam. A larger gap will reduce the bulging seen at the seam. A smaller gap reduces the visual appearance of a seam. For a well-tuned printer with pressure advance, a value of 0-15% is typically optimal.

- **Role-Based Wipe Speed**: Controls the speed of a wipe motion, i.e., how fast the nozzle will move over a printed area to "clean" it before traveling to another area of the model. It is recommended to turn this option on, to ensure the nozzle performs the wipe motion with the same speed that the feature was printed with.
|
||||
### Nearest

|
||||
Will place the seam at the nearest starting point compared to where the nozzle stopped printing in the previous layer.
|
||||
This is optimized for speed, low travel, and acceptable strength.
|
||||
|
||||
- **Wipe on Loops**: When finishing printing a "loop" (i.e., an extrusion that starts and ends at the same point), move the nozzle slightly inwards towards the part. That move aims to reduce seam unevenness by tucking in the end of the seam to the part. It also slightly cleans the nozzle before traveling to the next area of the model, reducing stringing.
|
||||
|
||||
|
||||
- **Wipe Before External Perimeters**: To minimize the visibility of potential over-extrusion at the start of an external perimeter, the de-retraction move is performed slightly on the inside of the model and, hence, the start of the external perimeter. That way, any potential over-extrusion is hidden from the outside surface.
|
||||
### Back
|
||||
|
||||
This option places the seam on the back side (Min Y point in that layer) of the object, away from the view. It is useful for objects that will be displayed with a specific orientation.
|
||||
|
||||
|
||||
|
||||
### Random
|
||||
|
||||
This option places the seam randomly across the object, which can help to distribute the seam points and increase the overall strength of the print.

|
||||

||||
This is useful when printing with Outer/Inner or Inner/Outer/Inner wall print order, as in these modes, it is more likely an external perimeter is printed immediately after a de-retraction move, which would cause slight extrusion variance at the start of a seam.

However, due to mechanical and material tolerances, as well as the very nature of 3D printing with FFF, that is not always possible. Hopefully with some tuning you'll be able to achieve prints like this!

The order of wall printing plays a significant role in the appearance of a seam. **Starting to print the external perimeter first after a long travel move will always result in more visible artifacts compared to printing the internal perimeters first and traveling just a few mm to print the external perimeter.**

For optimal seam performance, printing with **inner-outer-inner wall order is typically best, followed by inner-outer**. It reduces the amount of traveling performed prior to printing the external perimeter and ensures the nozzle is having as consistent pressure as possible, compared to printing outer-inner.
