Company News| Creality Upgrades CR-10 V2 to CR-10 V3 With Titan Extruder Default Added On

In September 2019, Creality added CR-10 V2 to the CREALITY CR-10 series family. Compared to its predecessor CR-10, Creality CR-10 V2 is reinvented with 9 upgrades, making this new version quickly created some buzz in 3D printing communities.
 
On CR-10 V2, Creality reserves some DIY upgrade space for makers, making them able to enjoy both 3D printing fun and DIY upgrade fun. The Titan extruder on CR-10 V2 is optional for DIY upgrades which usually requires some professional skills, therefore, users at entry-level or hobbyists without sophisticated mechanical skills usually encounter some technical issues. Considering providing better user experience with simple operation, Creality decides to upgrade the V2 to V3 with Titan extruder.
 
Brief a direct Titan extruder:
The direct extruder is right above the hot end with little space in between, which enables the extruder to push the filament directly into the nozzle. Since it minimizes the distance for filament traveling to the hot end, the direct extruder is more helpful and reliable when producing 3D prints with flexible soft filaments like TPU and ABS. Furthermore, the biggest benefit for using direct extruder is easier filament retraction thus avoiding filament stringing and oozing during printing.
One major disadvantage of having the direct extruder so close to the hot end is adding more weight to the print head. It shall contribute to problems when printing quickly, like ripples on the final prints, for there might be overshooting and lurch caused by the print head when it changes direction.
 
Opinions on Direct Extruder
Having a direct extruder means that you will enjoy the four benefits as shown below:
1. More reliable extrusion. As mentioned above, the direct extruder effectively shortens the traveling distance for the filament to go through the nozzle, which is quite helpful for reliable extrusion.
2. Quicker retraction. Retraction is a process of pulling the filament backward away from the nozzle which happens when the hot end is moving across an open space so that the melting filament won't ooze.
3. Less motor drive. The shorten distance not only guarantees reliable extrusion but also requires less strength to push the filament.
4. More supportable materials. With a direct extruder, users will enjoy impressive printing experience even with flexible and abrasively soft filaments.
 
For those who purchase CR-10 V2 before, the detail Titan extruder DIY upgrade tutorial is as shown below.
 

 
1. Remove the extruder cover and fixing screws, and prepare the direct extruder cover connector, and then remove the blue cable clip.
 
2. Preheat the nozzle to 195℃, press down the large pneumatic joint, and pull out the Teflon tube. Lose the large pneumatic joint and take it off.

 
3. Cut a short section of the Teflon tube (Make both ends flat), insert the Teflon tube in. Then cut off the extra section of the Teflon tube (Make it according to the heat sink).

 
3. Install the direct extruder connector to the top of the heat sink. Then install the Titan extruder to the director extruder connector. Fix the extruder cover to the extruder with three M3*32 screws and one M3*25 screw.


 
4. Fix the motor support with M3*8 screws

 
5. Remove the E-axis motor cable. Then connect the E-axis motor cable to the extension cable.

 
6. Prior to Creality Slicer settings, connect the machine to the computer with a USB cable. Set serial port and baud rate parameters.
 
7. Select and upload specified firmware.

 
8. Follow operations as follows: Control – Initialize EEPROM to restore the machine to factory settings – Control – Motion – Steps/mm – Estep's/mm, check the extruder firmware upload progress.
