What's new in the Pro model?

1. Improved Mechanical Properties

The Ender 3 Pro has been redesigned with a more sturdy, 40×40 aluminum extrusion for the Y-axis base. This should improve the overall stability of the printing surface.

Also, better bearing wheels deliver more stiffness, reduce friction, give better dimensional stability – and also help to reduce the overall noise level.

2. Improved Extruder

According to their press release, Creality also exchanged their extruder to an “MK-10” version. The company boasts it should “greatly reduce the risk of clogging and uneven extrusion”.

3. New Magnetic Printing Surface

Last, but not least, the Ender 3 Pro now comes equipped with a “C-MAG” magnetic printing bed. The sheet is removable and flexible, so the prints can be plucked off the build plate more easily. According to Creality, their textured surface adheres to all types of filament better than traditional methods such as tape, glue, or hairspray.

4. Improved Power Supply

Power supply was replaced with better Meanwell power supply

5. Vent changes

The Vent on the controller move to the bottom of the enclosure to prevent dust and other particles from falling in

Machine advantages

1.Split type design: the electronic control host and the mechanical structure are separated, open your mind, help create a variety of print-outs at will.
2. Shipment of the kit: Solving the problem of large-kit transportation, installation takes only 5 minutes.
3. Industrial grade circuit board: The technology is quite mature and stable, it can work continuously for 200 hours without pressure.
4. Linear pulley system: Patented technology, V-profile+precision pulley, runs more smoothly, more wear-resistant. Effectively reduces noise.
5.MK10 Extrusion Mechanism:A brand-new patented infrastructure that effectively reduces the risk of plugging and poor spillage and can print almost all filaments on the market.



Specifications

• Upgrade your Creality 3D Printer Extruder with our New "Metal Aluminium Anodised" Upgrade Kit.
• Our kit includes all the necessary screws & parts needed to directly replace your original creality plastic extruder.
• All you have to do is unbolt the old original creality plastic extruder & screw in the new "Metal Extruder" and you are ready to start printing.
• The advantages of a metal extruder is that you have better, stronger pressure pushing the filament into the printer nozzle so it will improve on the printer's performance.
• Our extruder kits have an adjustable bolt so that you can adjust the pressure of the extruder gear as needed.
