The casing is the frame that holds everything together and protects you from moving parts and heater elements. The more rigid the frame, the more precise the printer movement will be.
This takes the 120V AC electricity from the wall and converts it to low voltage DC power for your printer to use. The On/Off power switch on the lilm8 Printer is also located on the Power Supply Cord.
Some prints have some LCD screen so they can be controlled directly without a computer connection. These can be basic displays or advanced touchscreen.
The lilM8 uses control knob that allows you select the menu options featured on the printer.
Printers like the lilM8 have to accept a Micro SD card, pre-loaded with 3D model files ( or G-Codes) to print from. This allows 3D printers to run independently without a computer or motherboard
The LilM8 has a port for a standard USB AB printer cable needed to interface to a computer when firmware updates are required.
This is the plastic used by a 3D printer to create a 3D model. It comes on a spool and requires a filament holder that allows the spool to rotate freely as the filament is slowly drawn into the printer. There are many different filament colors and materials to choose from.
This is where the filament is fed into the printer. The lilM8 uses a spring clamp to allow the filament to be inserted into the Boden Tube when opened and secured when closed.
This plastic tube feeds the filament from the intake mechanism to the extruder.
The extruder is the core of the printer where the filament gets drawn in, melted, and pushed out. The extruder consists of two parts; the cold end(1) has a motor that draws the filament in before pushing it through to the hot end (2) where the filament gets melted and directed out through the nozzle.
The Nozzle is a metal component with a small hole for the melted filament to extrude from. Nozzles are interchangeable and come in various sizes.
The Print Arms positions the print nozzle along the X, Y, and Z axes when the printer is operating.
Unlike regular DC motors, which rotate continuously when given power, steeper motors rotate in increments. This give them precise control over their position.
This fan cools off the plastic immidiately after it is deposited by the nozzle. It helps the object hold its shape. It is not to be confused with the heat sink fan, which cools the hot end itself and not the printed object.
The print bed is the surface that your 3D printer is printed on to. Print beds can be heated (to assist the model adhession) or cold (as used by the lilM8).
X and Y motors and sprockets drive belts that move the print bed.
Bed Sheets help filament adhere to the print bed during printing and also make it easier to remove a print once completed. There are many different kinds of bed sheet materials.
Threaded Rods or Leadscrews can be turned to adjust a printer’s Z-axis.
These 4 screws at either corner of the Print Bed allow you to make height adjustments when leveling the bed.
