Printer Guide| Creality CR-6 SE Test Printing with PETG: How was the Print Quality?

On June 5th, Creality CR-6 SE enjoyed quite a successful end with a total pledge of over $4.3 million by 10,401 backers. Designed to be the most hassle-free 3D printer, CR-6 SE created quite a buzz in the 3D printing community for its innovative auto bed leveling tech and its revamped stylish design.
 
Considering the practicability, CR-6 SE is capable of printing with PLA, PETG, TPU, ABS, and more. This unit also tries to deliver high reliability with print precision of “up to ±0.01mm.”As curious as our customers, Creality unveiled some secrets on PETG printing in a Facebook and YouTube live stream. Let’s probe into some details!
 
The test model is a Benchy that it chose from the SD card. With nozzle temperature set at 250C, and bed temperature set at 80C, the Benchy turned out satisfactory. Overall, this model gave a glimpse of the exact quality that the CR-6 SE is capable of delivering.

At the very beginning, the print speed was set at 100mm/s. Owing to the advantages of the Carborundum glass platform, the first layer adheres to the print bed quite well. After 30mins printing, the print speed was adjusted to be quicker. During the one-hour live stream, the model was finished 15% after times of speed adjustment.

CR-6 SE Autodesk Kickstarter Test Results
Autodesk research scientist Andreas Bastian has developed a test procedure designed to help creators better calibrate their machines and showcase their printers’ capabilities to backers on Kickstarter. He developed a single, consolidated STL file that tests a printer’s dimensional accuracy, resolution, and alignment. For example, poor execution of the “bridging” feature shown below will lead to a saggy and stringy print. A well-calibrated printer will make the horizontal feature with fewer of those issues.
 
Test Results of CR-6 SE
1. Dimensional Accuracy: Score of 4
Target Measured X Measured Y X error Y error
25 24.78 25.07 0.22 0.07
20 19.90 19.93 0.1 0.07
15 14.97 14.89 0.03 0.11
10 9.86 10.03 0.14 0.03
5 4.91 4.93 0.09 0.07
 
Standards:
• If the overall average error is greater than 0.40mm, it is scored as "1".
• If the overall average error is between 0.31 and 0.40mm, score "2".
• If the magnitude of the overall average error is between 0.21 and 0.30mm, score "3".
• If the overall average error size is 0.11 and 0.20mm, score "4".
• If the overall average error is between 0.0 and 0.10mm, score "5".
 
Results:
Target 25 = X: 24.78mm / 0.22mm Error | Y: 25.07mm / 0.07mm Error
Target 20 = X: 19.90mm / 0.1mm Error | Y: 19.93mm / 0.07mm Error
Target 15 = X: 14.97mm / 0.03mm Error | Y: 14.89mm / 0.11mm Error
Target 10 = X: 9.86mm / 0.14mm Error | Y: 10.03mm / 0.03mm Error
Target 5 = X: 4.91mm / 0.09mm Error | Y: 4.93mm / 0.07mm Error
X Error Average = 0.116
Y Error Average = 0.07
 
2. Fine Flow Control: Score of 2.5
Measuring Method: Measure each of the spikes with the vernier caliper.
If the length of the spike is shorter than 30mm, score "0".
If the length of the spike is longer than 30mm, but there are some strings in between, score "2.5".
If the length of the spike is longer than 30mm, and there are no strings in between, score "5".
 
 
3. Fine Negative Features: Score of 5
Measuring method: Manually remove all the pins from the holes.
    If no pins can be removed, score “0”.
    If 1 pin can be removed, score “1”.
    If 2 pins can be removed, score “2”.
    If 3 pins can be removed, score “3”.
    If 4 pins can be removed, score “4”.
    If 5 pins can be removed, score “5”.
 
 
4. Overhangs: Score of 5
    If there is curling, sagging, delamination, or collapsing at 15°, 20°, and 30°, score“1”.
    If there is curling, sagging, delamination, or collapsing at 15°, 20°, score“3”.
    If there is curling, sagging, delamination, or collapsing at 15°, score“4”.
    If there’s same quality of surface smoothness at the four different degree, 15°, 20°, 30°, and 45°, score“5”.
 
 
5. Bridging: Score of 5
Standard: Bridging in 3D printing is an extrusion of material that horizontally links two raised points. To see whether there’s any bridging
 
    Record a “1” if more than 3 are in contact with the surfaces beneath them.
    Record a “2” if 3 bridges contact the surfaces beneath them.
    Record a “3” if 2 bridges contact the surfaces beneath them.
    Record a “4” if 1 bridge contacts the surface beneath it.
    Record a “5” if no bridges contact the surfaces beneath them.
 
6. XY Resonance: Score of 2.5
Standard: Visually inspect the X and Y ringing features, illuminating the test print from the side to highlight any ringing captured in the print. This example would score 0.
 
If rippling in the X or Y axis can be observed at or past three hash marks, record a “0”, otherwise, record a “2.5”.
 
7. Z-axis alignment: Score of 2.5
If a layer registration effect with a period equal to that of the leadscrew is visible on the pillar supporting the fine positive features test, record “0,” otherwise, record “2.5.”
 
CR-6 SE is such a simple and robust 3D printer featuring an intelligent leveling-free system for superior accuracy, making it a reliable choice that both hobbyists and pros can trust.Attaining such a craze buzz on Kickstarter, CR- 6SE will officially debut the retail market in July with a price tag of $429.Check more information on CR-6SE in the link below:
