You&#8217;ll need to set a few parameters that will help the slicer software determine how to slice your objects.<\/span><\/p>\n<p><span style=\"color: #dedede\"><strong>Layer Height<\/strong>: (good choice: 0.24mm or 0.20mm) how tall each layer of extruded material will be. Generally, our printers work well in a range of 0.15mm to 0.30mm for layer heights. A good place to start is 0.2mm for Prusa printers and 0.24mm for Bambu printers.<\/span><\/p>\n<p><span style=\"color: #dedede\"><strong>Filament<\/strong>: (good choice: PLA) this is the type of plastic filament that the final object will be made of. Most of our prints are done with PLA.<\/span><\/p>\n<p><span style=\"color: #dedede\"><strong>Printer<\/strong>: select the model of printer you&#8217;ll be using (MK4, P1S, etc.).<\/span><\/p>\n<p><span style=\"color: #dedede\"><strong>Supports<\/strong>: sometimes models will have overhangs&#8211;places where the the model isn&#8217;t supported by material underneath it. In these cases, you&#8217;ll need to add supports so that the overhangs have something to build on. The slicer software will automatically design supports when slice your model if you&#8217;ve turned this feature on. You&#8217;ll remove the supports after the print finishes. Each slicer software allows you to manually add supports by painting areas that you think will need them, or selecting overhangs automatically by incline angle.<\/span><\/p>\n<p><span style=\"color: #dedede\"><strong>Infill<\/strong>: (good choice: 15% or 20%) the interior of a 3D print volume is usually not filled with 100% plastic. It&#8217;s a combination of a support structure infill and open space. The infill is the percentage of interior space filled with supportive material. For example, 15% infill fills 15% of the interior space with plastic. There are many types of infill patterns (like rectilinear, gyroid, or grid) that you can manually choose, but the default settings are usually sufficient. You&#8217;ll need to choose the percentage of infill&#8211;good choices are usually 15% or 20%. More infill slows the printing and can cause issues with uneven heating\/cooling.<\/span><\/p>\n<p>\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-da7430d e-flex e-con-boxed e-con e-parent\" data-id=\"da7430d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b1610f6 elementor-widget elementor-widget-text-editor\" data-id=\"b1610f6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3><span style=\"color: #dedede\">Export and Transfer To Printer<\/span><\/h3>\n<p><span style=\"color: #dedede\">Once you&#8217;re done setting up the print and slicing it into g-code, you&#8217;ll export the g-code to the printer. This can be done wirelessly or via removable media like an SD card or USB flash drive.<\/span><\/p>\n<p><span style=\"color: #dedede\">Load the g-code onto the printer, then navigate the printer&#8217;s menus to start your print.

Follow the on-screen instructions for how to do this.<\/span><\/p>\n<p><span style=\"color: #dedede\">Find your g-code, and select it to start printing!

If you remove your print right away, watch out for places where it might still be hot, especially the base where it is connected to the build plate.<\/span><\/p>\n<p><span style=\"color: #dedede\">Remove the build plate from the printer and bend it so that you release parts of your print. Some prints will fall right off, others might need a bit more coaxing to fully release. You can twist, wiggle, or pry your parts off. Please don&#8217;t use metal tools to scrape your prints off the build plate. It can damage the coating on the steel plates. Instead use a plastic scraper as a last resort to releasing your part.<\/span><\/p>\n<p><span style=\"color: #dedede\">Once the build plate is clear, please spray the plate with 91% isopropyl alcohol and wipe it down with a paper towel. This removes any oils that have built up on the plate. If left uncleaned, future prints might not stick to the build plate.<\/span><\/p>\n<p><span style=\"color: #dedede\">Remove support material carefully from your print. You can recycle the support material in our recycling boxes in the 3D printer room.<\/span><\/p>\n<p><span style=\"color: #dedede\">Enjoy your new 3D print!
