Initial Layer Line Width: 100%. 9 Raft Air Gap. This results in better overhangs because the walls will stick to the already printed infill. Many people love going for the line width that is 120% of their nozzle diameter. Line width is actually the setting that determines the width of the tool path during printing. This setting instructs the printer to stop extruding at the end of printing the infill before it starts printing the walls. The result is a dense infill near the top layers, which is essential, and a reduced print time. Line Width: 0.4 mm Wall Line Width: 0.4 mm Outer Wall Line Width: 0.4 mm Inner Wall(s) Line Width: 0.4 mm Top/Bottom Line Width: 0.4 mm Infill Line Width: 0.4 mm Skirt/Brim Line Width: 0.4 mm Support Line Width: 0.4 mm Initial Layer Line Width: 100%. This makes the infill sturdier and it stabilizes the extrusion flow at the start of an infill line. To optimise the printing process most parts are printed with solid shells and filled with infill. The myths about layer height With a 0.4mm nozzle, it’s possible to have a line width of 0.3mm or even 0.8mm. Considering a 0.40mm nozzle having a 0.80mm flat with a 0.20mm layer thickness have a maximum line width of 1.00mm. (Just increasing the infill line width also works to make "2D infill patterns" even stronger.) However, be aware that with high print speed typically used for infill, increasing infill line width can easily exceed the capability of your hotend, resulting in underextrusion, extruder skipping, and stringing all over the place. Depending on how you adjust your line width, you can get different results out of your models. This also coincides with the auto line width settings by some of the slicers. Not only will this allow you to get great strength in your models, but you’ll find that the printing time will shorten as well. The solid layers at the top of your part will need to print on top of this foundation. A member of RepRap’s community says that he uses a fixed value of 0.5 mm for his line width setting regardless of his nozzle diameter and that gives him satisfactory results. So for a 0.4mm nozzle the preferred width would be 0.48mm; I use 0.44mm as I want higher detail and don't have any problems. You can already control the width of the infill and top and bottom infill independently. There are many options when it comes to 3D printer bed adhesives, and it can start to get people confused on what they should be using. On the contrary, if you decrease your line width in accordance with your nozzle diameter, that can turn out beneficial too. The skin (top and bottom layers) in a model is printed to reach the minimum thickness set in the print profile. You can use this formula now to calibrate your extrusion width. "A" is what started all of this. Since the layer height of the infill is not important for visual quality, you can use thicker layers on the infill to reduce the print time. The minimum infill area strengthens the legs of this coupler by filling it completely with skin. If you use auto in Simplify3D it will add 20% to your nozzle diameter. (Just increasing the infill line width also works to make "2D infill patterns" even stronger.) A positive value moves it UP and RIGHT, while a negative value moves it DOWN or LEFT. What you can do is increase just the Wall Line Width for better strength, while having a lower line width for the infill to improve on speed, since the walls contribute the most to part strength. Top surface skin line width: This line width is only available when a top surface skin is used. The skin overlap influences all top and bottom layers in a print. When adjusting this setting, always make sure that it is a multiple of the layer height, otherwise Ultimaker Cura will round it up to a multiple of the layer height. There has been quite a bit of confusion among 3D printer users when talking about line width, and why you might want to adjust it for your models. This will make your part very efficient in doing what it normally does, and all at the same time as thin or normal extrusions. The initial line width is the width of the lines of the initial layer. Reduce this threshold to use more, thinner lines. The conditions for a good print start, quite literally, from the ground up. This relates to the width of the infill in relation to the outside layer width. For those of you who are new to this, E-steps are the number of steps that the stepper motor takes for extruding 1 mm of filament. If you find the result different than what’s normally known as 1.75 mm, enter the measured value in your slicer. If the lines need to be printed in a different direction, you can set it here at 0° for vertical and 90° for horizontal. I also specify speeds for everything. I’m sure you can picture the other side of this equation where a thinner line width is likely to make your 3D printed parts weaker. Some people have actually tried printing with narrow line widths and seen worse results, so there are other factors that come into effect. This makes the infill sturdier and it stabilizes the extrusion flow at the start of an infill line. You do this by first checking out your E-step calibration and confirming that it’s good to work with. Infill line width: The line width of all infill … The following is a list of extrusion width ranges for different sized nozzles. A lower value will only marginally increase the strength. For a 0.4 mm nozzle, it would be a great idea to shoot fora line width of between 0.35-0.39mm. Expanding this slightly allows protruding model elements to have better adhesion to the rest of the model, making it stronger or lighter. Support material - As with the infill options, a thicker extrusion will speed up print time. The maximum line flat should be equal to the nozzle flat. The line width setting in 3D printing is simply how wide your nozzle extrudes each line of filament. In combination with a higher Extra Infill Line Count, some parts are not generating infill lines. It’s called the “Calibration Cube” which you can get it from Thingiverse. The initial line width is the width of the lines of the initial layer. The default value in Ultimaker Cura will in be sufficient in most cases. This determines the distance between each infill line, which has the same effect as changing the infill density. We prefer almost all of our PLA prints to have an 8% infill overlap. The result would be their ideal line width value. What is the Line Width Setting in 3D Printing? On the other hand, if the initial line gets way too thick, it starts crossing over the next set of layers, thereby forming raises and bumps in your print. Filament Flow: 1. A visualization of the infill overlap and wipe distance. The Slic3r software has a calculation which sets extrusion width to 1.125 * nozzle width as a default, and users have said how amazing their top surfaces were. You can check your E-step efficiency by printing 100 mm of filament and then measuring the length of what’s extruded. This will depend on your project. The model on the right has a higher infill density than the model on the left. This parameter will prevent small skin (top and bottom) areas from expanding. In terms of strength, you can look towards the Wall Line Width and the Infill Line Width. It provides a nice mix of strength and adhesion without sacrificing print quality. The Infill Extrusion Width value can be increased to 200% or even 300% to make it so that more material is extruded for the sparse infills. However, be aware that with high print speed typically used for infill, increasing infill line width can easily exceed the capability of your hotend, resulting in underextrusion, extruder skipping, and stringing all over the place. Flat surfaces with protruding elements in the Z-direction will have a stronger base, making it sturdier. General. From left to right; A preview of the model, skin expansion of 0.8mm, no skin expansion or removal, skin removal of 0.8mm. After calibrating the extruder steps, I wanted to optimize the line width and flow compensation parameters. It is a simple rectangle allowing for 3 perimeter laps at .4mm width, and a single .6mm infill bead, allowing for 15% infill overlap per side: Even with "infill line width" set to .4mm, Cura 15.06.2 refuses to infill: Forcing extra bottom layers gets a fill: There is going to be less material and a lower thickness, so under a certain amount of pressure, you may find parts breaking if you significantly reduce your line width. Tracking cookies enhance your experience on our website and may also collect your personal data outside of Ultimaker websites. Support cubic infill This infill gets automatically denser depending on the distance to the nearest top layer (the infill density increases only in the Z-axis). A How-to Guide. However, it might also reduce the visual quality of the print, as a value that is too high could lead to over extrusion. 9 Raft Air Gap Layer 0. How Do I Get the Perfect Line Width Setting? People have tried and tested and the majority of them agree that 120% of line width bodes well for most print jobs. 9 Raft Base Speed. For instance, if you go for 200% line width as described in the video above, you’ll get high strength mechanical parts. Do keep in mind that your infill pattern can have a significant impact on timing when adjusting your line width settings. Print speed is definitely affected by what line width you choose to set in your slicer. The line width of the inner and outer walls can be adjusted separately. At this angle, both the X- and Y-motor work together to obtain maximum acceleration and jerk on the layer without losing quality. During the infill you don't get solid lines but after a few layers only "dots", like little towers with no plastic between them. This isn’t very complicated, but you will be needing a Digital Caliper. The line width can be set individually for all line types available: Wall line width: The width of a single wall line. Minimum Variable Line Width: The smallest line width, as a factor of the normal line width, beyond which it will choose to use fewer, but wider lines to fill the available space. Therefore, there’s not a single “perfect” setting that works for everyone. If you agree with the use of tracking cookies, click “I agree, continue browsing”. People have had great success with this line width setting. If you want your print to be strong, choose infills like Grid, Solid Honeycomb and Triangular. By default, Cura also suggests, “slightly reducing this value could produce better prints.” This is true in many cases and can be beneficial for the quality of your prints. The skin overlap works in the same way as the infill overlap, which is described in detail above. Increasing the width of these two settings can definitely improve your overall part strength since it will make the important sections thicker. Layer Thickness: 1. The printer will still ooze a little bit of filament due to the pressure in the nozzle, but by stopping the extrusion early, you'll reduce over extrusion on the shell.

However, this is not going to be without compromising the quality. It will change the pattern of infill and the top surface of prints, therefore affect the print quality in terms of dimensional accuracy and surface quality. 9. INFILL TAB. I think Slic3r's is as well but not 100% positive on that one. Top/bottom line width: The line width with which the top and bottom layers are printed. It serves several functions like... 3D Printerly is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Continue reading about Material settings. The print should have no infill and no top or bottom layer. This might not work for everyone, but it has worked for many. The outermost line of the outline parameter is moved inwards by half the extrusion width value on either side of the print. I think Slic3r's is as well but not 100% positive on that one. See the image above. In this highly descriptive video, CNC Kitchen explains how increasing extrusion lends strength to your parts. 8 Surface Line Width. A bigger value results in longer, but sturdier prints. Every gradual infill step divides the infill percentage by a factor two. Cura mentions that decreasing your line width can help out with getting more precise prints, as well as smoother and higher quality parts. Line Width: 0.4 mm Wall Line Width: 0.4 mm Outer Wall Line Width: 0.4 mm Inner Wall(s) Line Width: 0.4 mm Top/Bottom Line Width: 0.4 mm Infill Line Width: 0.4 mm Skirt/Brim Line Width: 0.4 mm Support Line Width: 0.4 mm.
