What is 2.5D Engraving?
2.5D engraving is employed to craft designs that appear three-dimensional but are actually flat or with limited depth. In 2.5D engraving, the artisan maneuvers the cutter machine across the material surface, removing material to create shapes, patterns, or text. Unlike traditional 2D, where engraving is done on a flat plane involving only two axes, typically the X and Y axes, resulting in completely flat patterns or designs with no depth or three-dimensional effect, 2.5D laser engraving operates solely in two dimensions but with varying depths. This creates an illusion of depth and three-dimensional effect in the final engraved piece, adding a tactile quality to the engraving outcome.
How to achieve 2.5d Engraving?
Let's start doing it with me now.
Step 1: Obtain an STL file
-
Before diving into 2.5D engraving, the crucial first step is obtaining the correct file: an STL file. A recommended website for this is www.cults3d.com, which offers a variety of files, both free and paid. With its rich resources, you're sure to find a suitable material for your project, which can then be used with your cutter machine to bring your design to life.
- Find a free material and try to practice it
Step 2: Convert STL to PNG
- Utilize a search engine like Google to find an STL to PNG conversion tool. You'll come across various free conversion websites.
- Upload the STL file you downloaded and proceed with the conversion.
Step 3: Fine-Tuning
If you lack Photoshop, you can skip this step, but if you have it:
- Remove the background of the image.
- Change the picture mode to grayscale.
- Adjust the DPI and size as needed.
- Generate the picture using Photoshop.
Step 4: Start 2.5D engraving
Now that we've completed the preparation work, let's move on to the next steps.
Input the PNG picture into LightBurn and configure the parameters according to the following specifications:
- Machine Type: Monport GP20
- Speed: 1000 mm/sec
- Frequency: 30 kHz
- Power: 75%
- Line Interval: 0.025 mm
- DPI: 1000
- Angle: 45 degrees
- Image Mode: 3D Sliced
- Passes: 100
Note the image mode must be 3D Slice and The size of the picture is 50*50mm, it will take approximately 1.5 hours to complete the engraving process.
