Fabric Materials For Laser Engraving
Both natural and synthetic fabrics are good candidates for laser engraving. Cotton and microfiber are however the most commonly laser engraved fabrics. Microfiber is made from polyamides (nylon), polyesters, and a mixture of polyamide and polyester.
Microfibers are very durable and this is precisely why they are commonly used for laser engraving. 100% cotton that has a tight weave can also result in breathtaking engraving.
If you decided to engrave on cotton, make sure you go for fabric that has tightly fitting threads because lose threads will not give a good result.
Other fabrics that are good for laser engraving include denim, felt, twill and fleece. These fabrics are durable enough to withstand the heat of the laser. You can use them to come up with aesthetically appealing specialty merchandise.
When engraving on fabric, it is best to go with high speed and low power. This gives the laser beam a chance to quickly burn away the top part in order to yield the desired effect. Before you start your engraving, test with a couple of swatches until you have found the perfect settings. This will ensure that you do not burn your fabric when you start laser engraving it.
As a rule of thumb, avoid engraving any fabric that has loose knitting, like terry cloth, because they are not sturdy enough for the process.

- Material Fixation: Secure the fabric in place using masking tape or specialized fabric holders.
Choosing the Right Laser Settings:
- Power and Speed: Adjust according to fabric type, thickness, and desired engraving depth.
- DPI (Dots Per Inch): Higher DPI settings result in finer details but may extend engraving time.
Advanced Techniques:
Halftone Engraving:
- Utilize halftone techniques for creating shades and gradients on fabric.
- Adjust laser power and speed to control the intensity of engraving.
Vector Cutting:
- Combine engraving with vector cutting for intricate designs on fabric.
- Experiment with different cutting depths for varied effects.
Masking for Protection:
- Apply masking tape or special fabric masking materials to protect surrounding areas.
- Remove the masking after engraving to reveal the finished design.
Best Practices:
Test Engravings:
- Conduct test engravings on a scrap piece of fabric to determine ideal settings.
- Adjust focus and alignment for precise and consistent results.
Ventilation and Safety:
- Ensure proper ventilation, especially when working with synthetic fabrics.
- Wear appropriate personal protective equipment, including eyewear.

Stone Materials For Laser Engraving
Marble and granite are great materials for engraving photos. This is mainly because granite and marble yield an awesome contrast when engraved.
If you use dark-colored marble or granite, you will get a high contrast so there will be no need to add color. The resultant image should be white or dark grey as long as the engraving is done properly.
But how do you know which one to use between marble and granite?
The easiest way to know which one to go with between marble and granite is to start by finding out where the engraved item will be displayed, i.e., will it be a wall hanging in a house or will it be displayed outdoors? If the piece will be placed inside, then you can use either marble or granite.
However, it is best to with granite for any pieces that will be exposed to the elements. That’s because granite is a harder material than marble. To put that into perspective, the Moh scale places marble at a 3 while granite is placed at a 7 in terms of hardness. Granite is close to diamond because the Moh scale gives the diamond a 10.
Understanding Stone Engraving:
Types of Stone:
- Marble: Known for its timeless beauty and veined patterns, marble engraving results in contrasting and visually striking designs.
- Granite: Recognized for its durability and speckled appearance, granite offers a robust canvas for detailed engravings.
Preparing Stone:
- Surface Cleaning: Ensure the stone surface is clean and free from dust or debris.
- Masking: Apply masking tape or film to protect areas not intended for engraving and reduce residue.
Choosing the Right Laser Settings:
- Power and Speed: Adjust based on the hardness and color of the stone.
- DPI (Dots Per Inch): Higher DPI settings result in finer details but may increase engraving time.
Advanced Techniques:
Image Conversion:
- Convert images or designs into grayscale for optimal contrast on stone surfaces.
- Experiment with various engraving depths to achieve three-dimensional effects.
Adding Color:
- Apply specialized stone paint or infills to engraved areas for enhanced visibility.
- Test compatibility and durability of colorants with the stone type.
Depth Variation:
- Utilize variable engraving depths to create textured effects on the stone surface.
- Experiment with shading techniques for realistic and artistic outcomes.
Best Practices:
Testing on Sample Pieces:
- Conduct test engravings on small, similar stone pieces to determine optimal settings.
- Account for variations in stone hardness and composition.
Ventilation and Safety:
- Ensure proper ventilation to manage dust and potential fumes during the engraving process.
- Wear appropriate safety gear, including respiratory protection, to safeguard against particles.
Fixating Stone:
- Secure the stone in place using specialized fixtures or clamps to prevent movement.
- Consider using a rotary attachment for cylindrical or rounded stone surfaces.
Understanding Stone Characteristics:
- Recognize that different stones may react uniquely to laser engraving.
- Adjust settings based on the hardness, density, and color of the specific stone.
