¶ Wall Line Count
¶ 1. Wall Line Count
Concept description: Refers to the number of walls. When calculated based on wall thickness, the value will be rounded to an integer. This setting determines how much of the outline is drawn around the print on each layer.
Only one of the walls is the outer wall and has Outer Wall Settings printed on it. The remaining walls will be printed with the inner wall settings. The number of walls is the main factor affecting print strength. Because the inner and outer walls are adjacent they can reinforce each other, creating a stronger component. For larger print targets, this may be a more efficient way to achieve a sturdier object than adjusting the infill, depending on the shape.
Increasing the number of walls will:
• Greatly improve the strength of printing.
• Reduces the transparent effect of the fill pattern that is visible from the outside.
• Improve drape, as wall lines are usually more toward the nearest rest point.
• Makes models easier to waterproof.
• Dramatically increase printing time and material usage for your prints.
¶ Top layers
¶ 1. Top layers
The number of top layers refers to the number of top layers, which is rounded to an integer when calculated based on the thickness of the top layer. This setting is configured at the top of the print target and represents how many solid layers to print. These solid solid layers are printed, not filled. Their purpose is to enclose the top.
More top layers have a variety of effects that are good for top surface quality and print quality but are detrimental to the quality of the print target. Productivity.
• Having more top layers means that a small portion of the print will be filled with sparse fill.
• The top surface will be smoother. The rough texture of the top surface of the print target will be smoothed to some extent in the layers on top.
• Because more layers are fully filled, The top surface will be very strong and even waterproof because the top layer is sealed by the padding.
• Because more layers are fully filled, printing consumes more consumables.
• Printing on the target will take longer because more material must be placed, and the top layer of these settings is usually smaller than Fill layer printing is slower.
¶ Bottom layers
¶ Bottom layers
The number of bottom layers refers to the number of printing target bottom layers. When calculated based on the thickness of the bottom layer, the value is rounded to an integer. This setting allows you to set the number of solid underlays for the print target. Higher values ensure that all gaps in the underlying layer are completely closed. However, this also increases printing time and consumable usage.
¶ Top surface skin layers
¶ 1. Top surface skin layers
This setting represents the number of top skin layers. Usually only one layer is needed, and the top layer is enoughGenerate a higher quality top surface.
Some settings can greatly improve the quality of the printed top surface, but since they apply to all skin layers on top, so it may make printing take longer.
A similar result can be achieved by adjusting these settings for only the topmost layer or two, but printing the remaining skin layers faster Effect. This does not have a particularly large negative impact on print times.
To get a better top surface, you can try reduce the speed and increase a certain printing acceleration.
¶ Fill gaps between walls
¶ 1. Fill gaps between walls
This setting means filling the gaps between walls where does not fit.
If you set full filling, the places with gaps in the wall of the printing target will be fully filled, which will consume more consumables and cost a certain amount of money. Print Time.
If no filling is set, there will be no further filling action during the printing process, and the printing speed will be faster, but the target wall The gap still exists.
¶ Vertical Expansion
¶ 1. Vertical Expansion
The setting of this parameter can adjust the vertical expansion distance of the print target during the printing process.
¶ Horizontal Expansion
¶ 1. Horizontal Expansion
This setting can be applied to offsets for all polygons in each layer. Positive values can compensate for oversized holes; negative values can compensate for oversized holes. Small holes.
Additionally, this setting makes the entire model slightly wider or narrower. It is a compensation measure for dimensional errors during the printing process.
Positive values make printing bolder. This reduces the idle walk size. Negative values will thin the print and increase the size of the free run.
This setting can be useful if printing tolerance is important. Due to slight distortion of the plastic, the actual dimensions of the print may not correspond exactly to the dimensions of the digital model.
Simply use the scale tool to scale the model on the build plate to compensate for gain error, but this setting can be used to compensate for the differences caused by the printing method offset error caused.
You can also use this setting if you know that your printer is always printing too wide due to excessive squeezing or inaccurate motion compensate.
¶ Z seam Alignment
¶ 1. Z seam Alignment
refers to the starting point of each path in a layer. When the paths of consecutive layers start from the same point, a vertical gap will appear on the printout. If the paths are aligned close to a user-specified location, the gap will be easily removed. If placed randomly, the inaccuracy of the path start point will be very unnoticeable. Typically, printing will be faster when the shortest path is used.
This setting allows you to select seam placement for each profile. There are a variety of options available that provide great control over where seams are placed to minimize their impact or allow you to more easily remove seams in post-processing.
The seam is where the outline print begins and ends. Even if the path of the nozzle is a closed circle, there will still be seams where the extrusion begins and ends because the printing process never will be completely accurate. With this setting, you can minimize the visibility of seams by hiding them somewhere or spreading them out.
¶ 1.1 User specified
This option allows you to manually select a location.
The seam will be placed in the corner closest to the selected location. This usually places the corners very closely together so that you can easily Cut out the seams.
It also allows fine-grained control of seam location. By default, the location on the back of the printer is selected.
The idea is that users mostly have the front of the model facing the front of the printer, so the back position can better hide the interface seam.
¶ 1.1.1 Z seam Alignment
If the seam position is set to User Specified in the Z Seam Alignment setting, the seam will follow This setting specifies the orientation placement.
The seam position has eight sequential directions. It's best to choose seam locations that are difficult to see in the final object, so this depends heavily on the design of the model.
It is usually best to choose the seam position of inner corners, but if there are no inner corners, you can also choose one that is easy to cut off with a knife after printing. Location. In effect, seams are placed as close as possible to where the Z Seam X and Z Seam Y settings indicate. This is a convenient setting that makes setting these coordinates more intuitive.
¶ 1.1.2 Z seam
The X-axis coordinate of the position around which to begin printing portions of the layer. If the seam position is set to User Specified in the Z Seam Alignment settings, the seam will Place it close to the position specified by the Z-stitch X and [Z-stitch Y] (#zfengy) settings.
If Z-Gap Relative is disabled, this setting indicates the absolute position on the build plate; if <span style= is enabled "font-weight: bold; color: darkblue">"Z seam relative" indicates the position relative to the center of the model.
Selecting seam locations that are almost invisible is useful in printing applications. If there is no such location, or some post-processing is possible after printing, you may choose to place the seams in a location where they can be easily cut away with a knife or sanded.
¶ 1.1.3 Z sewing Y
The X-axis coordinate of the position around which to begin printing portions of the layer.
If the seam position is set to "User Specified" in the "Z Seam Alignment" setting, the seam will be placed close to the "Z Seam X" and " Z seam at the position specified by the Y” setting.
¶ 1.1.4 Z seam relative
When placing seams at user-specified locations based on the Z Seam Alignment setting, you You can enter the coordinates where the seam must be located. Typically, these coordinates specify a location on the printing platform, such as the back of the printer. If this setting is enabled, these coordinates will be obtained relative to the model's position.
Disabled: The coordinates point to the absolute center of the build plate, so all white stripes point to the center.
Enabled: Coordinates are relative to the model, so each model will have white stripes in the same corner.
When duplicating the mesh on the print platform, this setting causes the seams of each copy to be positioned in the exact same place, rather than having them point to the same point on the print platform. This allows you to print each copy exactly the same regardless of their position on the build plate.
¶ 1.2 shortest
This option simply minimizes the movement distance to the seam without placing it in any specific location. Since the travel path is shorter, you save a small amount of travel time. The seams will also be slightly smaller because where the nozzle falls on the contour will place less ooze.
You can still maintain the desired corner preference by selecting a corner close to where the nozzle is. The closest corner is not selected, but a weighted preference is used to minimize stroke movement, while also setting the Seam Corner Preference Use appropriate corners.
¶ 1.3 Random
Choose random locations around the perimeter for the seam. This random position will change in each layer, so the seams will be almost evenly distributed around the model. The seams are barely visible due to the misalignment of the seams in the different layers. However, things look a little more confusing on the surface.
¶ 1.4 The sharpest corner
Seams will be placed throughout the outline based on the slit angle preference selected in the "Slit Angle Preferences" setting The sharpest gap angle. This may result in longer travel movements, but ensures maximum concealment or exposure of the seam depending on the preferences set for the gap corners.
¶ Enable ironing
¶ 1. Enable ironing
The significance of setting this parameter is to further melt the plastic filament on the top and create a smoother surface. After activation, the pressure in the nozzle chamber is kept high so that the creases on the nozzle surface can be filled with material.
To put it bluntly, the ironing process means that the printer will pass over the top surface repeatedly to make it smoother, which can be compared to some Life scenes such as ironing clothes. Printing speed during ironing will be relatively slower.
Ironing prints a pattern of lines on the top surface of the print.
This has two benefits:
• By passing the hot nozzle over the top surface multiple times, it melts the top surface again. That’s where the name “ironing” comes from.Because the movement speed is too slow and the line width is too small, the nozzle repeatedly jumps across the top, so it will heat the top surface very significantly. But then the flat part of the nozzle will smooth it out.
• It fills the gap on the top surface in the process. The ironing action is performed at the same height as the print layer itself. It has less iron-on extrusion flow than full layer, but still has some flow. Each time the nozzle passes over an uneven top surface, material from the nozzle flows into the gap, making it smoother and flatter. But the ironing function actually has some disadvantages:
• Because the ironing movement speed is very slow, it will significantly increase the model printing time.
• If the screeding process is interrupted (because it has to be moved to a different section), then the There are very obvious lines left between the ironed part and the post-ironed part. These lines will greatly affect the display effect of the printed model for the printed model. This can sometimes be avoided by setting the ironing pattern to a different pattern (such as concentric circles or something).
¶ Gap Angle Preferences
¶ 1. Gap angle preference settings
Generally speaking, there are two options for seam placement: hidden in the inner corner, or Exposed outer corners.
This setting allows you to control how seams are positioned relative to the corners in the model. Users can use multiple gap angle preference options to make the position of the gap appear at the desired corner of the model outline.
The following are the options available for this setting and their effects:
• None: Indicates that each corner does not affect the gap position, and there is no preference for corner points at all. The seam that best meets the Z-joint alignment requirements will be selected.
• Hidden seams: Makes gaps more likely to appear on the inside corners. This setting will prefer to hide seams at inside corners. If Z Seam Alignment is set to Sharpest Corner, the innermost corner is always selected. If you set it to Shortest, the inner corner closest to the current position of the nozzle is selected when you start drawing the outline.
• Exposed seams: This will favor seams that expose outside corners. This will make gaps more likely to appear on the outside corners.
• Hidden or exposed gaps: Will cause gaps to appear on the medial and lateral corners, more often on the medial corners if appropriate.
• Smart Hide: Allows gaps to appear on the medial and lateral corners, with more emphasis on the medial corners if appropriate.
