¶ MD1000D introduction
This page is an introduction to the main components of the MD 1000D printer so that you can have a general understanding of this printer.
¶ How does MD1000D work?
The MD1000D printer is a machine that uses plastic filament to create 3D objects.
In most cases, MD1000D can print 3D models in STL format, and the model file needs to be pre-processed using slicing software before printing.
Taking MINGDA Orca Slicer as an example, the slicing software divides the STL file into multiple layers. The information of each layer is automatically converted into a language that the printer can understand, which is used to guide the movement paths and speeds of each axis during the printing process.
In addition, the slicing software can also integrate a variety of parameter settings in the generated code, such as the printing temperature of the filaments, the extrusion speed of the printer, and generate support for certain parts of the printed model.
¶ Extruder
The extruder is responsible for pulling the filament out of the spool and feeding it into the hotend. After heating and melting, it is extruded through the nozzle to generate a printed model.
The extruder needs to accurately control the length of extrusion and retraction of the filament to ensure the dimensional accuracy and appearance quality of the printed model. It is one of the core components of a 3D printer.
¶ Hotend
The hotend assembly is the toolhead module's core component, consisting of a hotend heating assembly, a hotend (with nozzle, heat blocker, and heat sink), and a hotend silicone sock. The maximum supported heating temperature is 350°C. The hotend assembly heats the filament to a specified temperature, and the melted filament is deposited in the form of a thin layer to generate a model.
Different filaments often require different heating temperatures. For example, PLA materials are printed at lower temperatures around 210-220°C, while engineering materials need to be printed at higher temperatures around 300~320°C. The hotend equipped a high coat hotend, it increased the hotend life.
¶ Cooling fans
¶ Cooling fan for hotend
Fast printing requires good cooling of the Hotend. MD1000D is equipped with a customized 4010 fast cooling fan with 5,000 RPM. The fast cooling fan ensures fast cooling of the printed parts on the left and right hotends.
¶ Part cooling fan
Fast printing requires good cooling of the printed parts. MD1000D is equipped with a customized 5015 centrifugal fan and air duct. The cooling air blown out by the fan will be blown to the vicinity of the left and right hotends through the air duct, thereby ensuring fast cooling of the printed parts on the left and right hotends.
¶ Auxiliary part cooling fan
MD1000D is equipped with an additional cooling fan on the back side of the chamber. For some filaments (such as PLA), good heat dissipation helps improve printing results. Turning on the fan will form an "airflow layer" on the print, which helps to cure the print layer as quickly as possible.
¶ Build late
The MD1000D printer comes with a Textured PEI Plate.
Textured PEI Plate is made by coating a stainless steel sheet with a layer of PEI powder, creating a textured surface. What sets it apart is its special rough texture, which is transferred to the bottom surface of your prints. This plate works well with a variety of materials and often provides excellent adhesion without the need for adhesives, making it user-friendly. Additionally, the PEI coating on the plates is durable and has a long lifespan.
