The Ender 3 Pro is an UPGRADED VERSION of the Ender-3.
This printer is the favorite of many 3D Printing nerds, including me 😉.

DIY ASSEMBLY:
Enjoy the satisfaction of completing your own DIY 3D printer kit, while also becoming familiar with the inner workings of the machine and developing a deeper understanding of the principles behind 3D Printing.
 
NEXT GENERATION TECHNOLOGY:
- Thecontrol board offers state of the art, "Resume Print" technology. Should your printer suffer unexpected power outages, it will resume from the last recorded extruder position. Goodbye failed prints!
- The advanced MK-10 extruder’s genius design, greatly reduces the risk of clogging and uneven extrusion.
- High-precisions ball bearing wheels made from Delrin/POM engineering thermoplastic deliver high stiffness, low friction, and excellent dimensional stability helping to reduce noise levels greatly.
 
NEW Y-AXIS DESIGN:
Redesigned with a much more sturdy, 40x40 aluminum extrusion for the Y-axis base. This provides unprecedented stability for the printing surface, resulting in upgraded print quality.
 
SUPERIOR PRINTING SURFACE:
The all new state of the art “C-MAG” magnetic bed, is completely removable, and flexible. The textured surface adheres to all types of filament better than traditional methods such as tape, glue, or hairspray. No more model warping on larger prints! Once the model is finished printing, remove the magnetic upper from the lower and bend or flex the print surface to watch the model effortlessly popoff the printing surface.
 
BRAND NAME POWER SUPPLY:
Meanwell, a well-known company with over 30 years of experience in the power supply industry, manufactured power supply, ensures safer and faster heating of all necessary components.
 
RAPID HEATING:
Paired with the new high-quality power supply, the Ender 3 heated bed can now reach temperatures of 110*C in just 5 minutes. Making the Ender 3 suitable for many different types of filaments.
 
PRECISELY MANUFACTURED:
High-precision CNC machining techniques used for all metal brackets and mounts, guarantees precise positioning and an all around more stable structure.
 
ENHANCED BED LEVELING:
All new, ergonomically designed, larger bed leveling nuts, makes leveling the bed much easier and more precise, to make sure you spend more time printing, and less time leveling.

General Precautions for FDM 3D Printers:
- Do not let kids use the printer unattended from adults.
- Keep flammable materials away from the printer.
- Awoid contact with the Hotend / Nozle of the printer when heated.
- Do not let the printer work unattended.
- Do not work on electrical components of the printer, when they are powered.
Although, generally 3D Printing is a safe process, keep in mind when using this technology, allways safety first!
