![]() ![]() ![]() Reducing the Outer Wall’s Width slightly can result in a better-quality print and increase the wall’s strength. The default value in the standard Cura profile is 0.4mm. Cura provides the setting for modifying the Wall Line Width separately because changing it can provide several benefits. The Wall Line Width is simply the line width for the walls for the print. Also, don’t forget to adjust your flow rate when you change the Line Width, so your extruder can keep up accordingly. This will help you avoid under and over extrusion. However, when modifying this value, be careful to keep it within 60-150% of the nozzle diameter as a general rule. The default line width is the nozzle’s diameter (usually 0.4mm). If you want thinner lines, the printer will extrude less, and if you want wider lines, it’ll extrude more. The optimal Line Width of your printer depends on your nozzle’s diameter.Īlthough the nozzle’s diameter sets the baseline for the Line Width, you can vary the line width to extrude more or less material. The Line Width is the horizontal width of the layers lines the 3D printer lays down. ![]() This causes the first layer to sag more, resulting in a bulging look at the bottom of a 3D model. However, if your first layer is too thick, it can cause a print defect known as elephant’s foot. This leads to the layer being pushed properly into the print bed, resulting in a mirror-like bottom finish and strong adhesion. The increased layer thickness results in the printer over-extruding material over the surface. Most people recommend using a value of 0.3mm or x1.5 of the layer height for the best first layer adhesion. The default Initial Layer Height in Cura’s Standard profile is 0.2mm. 3D models usually require a thick first layer for a better “squish” or first layer adhesion. The Initial Layer Height is simply the height of your print’s first layer. Low Quality (0.28mm): Larger Layer Height that results in increased strength and faster 3D printing time, but rougher print quality.Standard Quality (0.2mm): Default value that offers a balance between quality and speed.Dynamic Quality (0.16mm): A balance between super & standard quality, giving good quality but not at too much expense of printing time.Super Quality (0.12mm): Smaller Layer Height that results in higher quality prints but increases the printing time.They include the Standard, Low and Dynamic, and Super Quality profiles. On the other hand, a thicker Layer Height increases the print’s strength (up to a point) and reduces printing time.Ĭura provides several profiles with various Layer Heights, offering varying levels of details. It heavily influences the final quality and printing time of the print.Ī thinner Layer Height offers you more detail and a better finish on your print, but it increases the printing time. The Layer Height controls the height or thickness of the print’s layer. They are a series of settings that you can use to fine-tune your print’s quality through Layer Heights and Line Widths. “The carbon nanotube-based gecko adhesives are going to open up opportunities to using these materials on robots, to climb vertical walls, and could actually be used in outer space (vacuum condition) because these materials stick without any liquid glue,” Dhinojwala says.Quality settings control the resolution of the print’s features. The dry adhesive, unlike liquid glue counterparts, promises successful use in extreme atmospheric and temperature conditions and in other applications that present challenges. “Also, if you apply a high pressure, the tubes bend and buckle and make a larger contact area with the surface, which is the reason for higher adhesion.” “We found out that the diameter of the tubes is an important parameter for adhesion because we have to balance the adhesion and bending rigidity of the tubes,” Ge says. Using a combination of mechanics, electrical resistance and scanning electron microscopy (SEM) to study the contact between hairs of a large number of vertically aligned carbon nanotubes with glass or silicon substrates, the researchers found that soft nanotubes clasp and curve when pressure is applied, contributing to their adhesive strength. ![]()
