These machines are limited in the materials they can print with. The specific temperature requirement depends on what type of filament is used. Print beds typically are kept somewhere between 122 and 212☏ (50 and 100☌). Most print beds are heated to prevent the plastic from cooling too quickly and creating product warp. The print bed is the surface on which filament is deposited in a specified shape during the printing process. This piece senses and helps regulate the temperature of the hot end. This cooling element helps keep heat from entering parts of the extruder that need to stay at lower temperatures.Īnother element of the extruder that is worth mentioning is the thermistor or thermocouple. The heating element melts the filament as it passes through the thermal tube and reaches the nozzle.Īlso within the extruder is a heat-sink fan. Typically, this is made of aluminum and is heated by a heater cartridge. Within the extruder’s hot end is the heating block.
It is composed of a cold end, which pulls filament through the system, and a hot end, which melts the filament as it is extruded. The extruder is where most of the printer’s technology is located.
The controls in this dialog are analogous to those in the Save As dialog.Ĭlicking Save opens the Export STL dialog, which is used to adjust the settings for exporting the STL file.A few key components create and manage heat within an FDM printer:Ī closer look at each will explain how they affect print outcome.Įxtruder. By default, Files of type is set to STL files (*.stl). The Save As Stereolithography File dialog opens. You can export an STL file by selecting an element (or selection set) and choosing File > Export > 3D Modeling File Types > Stereolithography (*.stl) or by using the key-in STL EXPORT. Selecting a file to import and clicking Open opens the Import STL dialog, which is used to adjust the settings for importing the STL file. The controls in this dialog are analogous to those in the Open dialog. The Choose an STL file to import dialog, a standard file selection dialog, opens. You can import an STL file by choosing File > Import > 3D Modeling File Types > STL (*.stl) or by using the key-in STL IMPORT. If you are exporting an STL file to send a model for 3D printing, you can use clip volumes to divide the output. Stereolithography (STL) files are basically lists of triangles that represent solid or surface geometry.
