3D Printer Calibration

3D Printer
Calibration Service

Our 3D-printer calibration method is based on our patented calibration block design with specific dimensions and geometric shapes to assess the tolerance of the 3D printer and to help fine-tuning the 3D printer settings to achieve better precision and accuracy. Client can print the OSSFILA’s calibration block, shipping to us and a report will be generated by our engineers. On the other hand, interested user can also print and assess the tolerance using our online report generator.

3D Printer
Calibration

By printing a single calibration block and measuring the dimensions of various features on the block with a micrometer and calliper, one can obtain the errors between designed values and the printed values. The calibration block has a predefined diameter for the sphere, cylinder, hole on the block, as well as the length in X, Y, and Z direction. The printability can also be verified by testing whether the block can be printed with any deformity at a certain temperature and environment.

Printing Tolerance
Quality Assurance

By printing the calibration block with the actually designated model at the same time, one can evaluate the tolerance and quality of the designated model by measuring the dimensions of the calibration block. If the calibration model’s dimension is within the acceptable tolerance, the tolerance of the designated should also be within the acceptable range. This produces a good quality reference of the dimensional tolerance without the use of expensive tools like coordinate-measuring machine (CMM) and vision measuring machine (VMM).

Global
Benchmarking

OSSFILA is developing a benchmarking database allowing the community and professionals to input their calibration block print measurement and compare the result with the global data contributed comprised of other 3D printer models. A report will be generated for free and you will know how you rank in terms of printing performance. OSSFILA would like to invite any pioneers to take part in the study. Simple download the block and access the calibration platform below.

Step-By-Step
Calibration Procedures

Calibrate your 3D printer to achieve the best possible print! Takes only 15 minutes.

Step 1: Click HERE to download the calibration cube file.

Step 2: Set your slicers setting as listed below:

Layer thickness: 0.15 mm (or set to your normal printer layer height)
Rafts: Yes
Support: Touching build plate only (or no support)
Infill density: 30%
Print speed: set to your normal print speed
Temperature settings: Depends on your printing material

Step 3: Save the G-code and print the cube.

Step 4: Remove the cube from the surface when the print has finished and cooled.

Step 5: Measure the values with a caliper and submit HERE:

Expected dimensions of following features:

X, Y, Z axis: 25 mm
Holes diameter: 10 mm
Trough: 20 mm
Crest: 20 mm
Cylinders: 10 mm
Sphere: 10 mm

Step 6: The calibration result will be sent to your email within 15 minutes.

Step 7: Adjust your slicer setting with the report.

Step 8: (Optional) Repeat the test with different filaments for more accurate results.

Tips

To know the dimensional accuracy of each of your 3D printed parts, you may print your desired items together with the calibration cube in the same run. Then measure the parameters of the calibration cube and submit the results as above.
