Warning: Certain materials may become highly hazardous during laser cutting or engraving. For your safety, exercise extreme caution
when processing these materials, understand the potential hazards they may pose, and take measures to protect yourself.
Materials
injury
PVC (polyvinyl chloride), vinyl,
leather, synthetic leather
Cutting releases toxic pure chlorine gas accompanied by a strong irritating odor! It is
recommended not to cut this material, as it may corrode machine tool metal components and
damage optical components and motion control systems. When cutting this material, wear a gas
mask or use an air purifier.
ABS
It releases cyanide gas and melts easily. It melts rather than evaporates, ignites readily, and
leaves behind a viscous molten residue. When handling this material, it is recommended that you
wear a gas mask and use an air purifier.
HDPE
Melting and highly flammable.
Expanded polystyrene foam
Melting and highly flammable.
Polypropylene foam
Melting and highly flammable.
Polycarbonate, Latex Paint
Change color and catch fire.
Coated carbon fiber
Release toxic gases.
Acrylic fiber (acrylic)
This material releases harmful gases. We recommend wearing a respirator or using an air purifier
when processing it. Note that most 450 nm lasers can penetrate acrylic. The C1 Ultra
semiconductor laser emits a beam wavelength ranging from 450 nm to 460 nm, meaning most
laser beams will pass through acrylic rather than being absorbed. Semiconductor lasers can only
cut a limited amount of non-transparent, translucent acrylic sheets. Compared to semiconductor
lasers, CO₂ lasers are better suited for processing acrylic.
Note: When processing blue surface materials using a laser module emitting a 455 nm laser beam, most of the laser beam will be reflected
rather than absorbed. You will need to increase the power to ensure proper processing.
Warning: Do not process reflective materials such as mirrors. Laser beam reflection is extremely dangerous and may cause injury to you
and damage to the laser equipment.

Cutting
Lasers can be used to cut wood, paper, cork, and certain types of plastic; they can also engrave most materials, such as wood, paper,
coated metals, stainless steel, plastic, marble, stone, tile, glass, and more.
Materials
Instruction
Warning
Most trees
Avoid using oily or resinous woods.
Exercise extreme caution when cutting oily or resin-rich
wood. These materials are highly flammable. Maintain a
cutting speed below 2% and power output at 10% when
processing wood.
Plywood, composite wood
They are glued together and may not be as satisfying as solid wood.
Medium-density
fiberboard, engineered
wood
They can be cut, but they may burn quite a bit.
Paper, paperboard
They can be cut easily and beautifully.
Cardboard, paper boxes
They can be cut easily, but they may catch fire.
Exercise caution around open flames and proceed with
care during cutting.
cork
They can be cut quite well. However, cutting results may be affected by the
thickness and quality of the cork. If there is too much glue, the cork may not cut well.
Avoid using thick cork.
Polycarbonate
Thin polycarbonate can be cut, but its color typically undergoes significant changes.
Keep the area well-ventilated and be mindful of fire
hazards.
Depron foam
It cuts beautifully with smooth edges, making it popular for hobbyist projects,
remote-controlled aircraft, architectural models, and toys.
Take special care when cutting.
Fabric, felt, hemp fiber,
cotton, leather
It can cut thin fabrics, felt, hemp fibers, cotton, or leather, but the edges may scorch
due to high temperatures.

Note
Warning
Glass
The texture of engraved glass resembles that of
sandblasted glass.
The beam emitted by the C1 Ultra's semiconductor laser
module cannot be used directly for engraving transparent
glass. Before engraving, a laser engraving machine marking
paper must be applied to the glass surface.
Ceramic tiles
The processing generates fumes and dust.
Anodized aluminum
It causes the anode coating to evaporate.
Painted, coated metal
It will cause the paint to evaporate.
Stainless steel
It will burn its surface and change its color.
Compared to semiconductor lasers, fiber lasers are better
suited for processing metal products.

Questions
Solutions
What type of laser source does the
machine use?
It is a semiconductor laser
What happens if the machine loses power
during operation?
When power is cut off during an engraving task, the laser head will remain in place.
When the power is turned on again, the machine will initialize and will not continue to
perform the original task.
Why can't the pattern be engraved at all
(or the engraving is very shallow)?
The imported picture should be clear and the color should not be too light; before
engraving, please make sure the focus is correct and the power, speed and time
settings are appropriate.
What if the pattern is not engraved
completely (or the depth is inconsistent)?
Please make sure that the engraving object is flat, the machine is level, and it has been
adjusted normally according to the operating instructions.

Questions
Solutions
How to focus the C1 Ultra laser engraving machine?
Place the material on the stage, lower the left knob to focus, and lock it after focusing. For example,
engrave and cut a 2mm thick basswood board.
Will the working platform be damagedduring laser
engraving?
During the engraving or cutting process, the laser may penetrate the object and leave marks on the
work surface. Be sure to place an object that the laser cannot penetrate under the engraving object,
such as: stainless steel plate, aluminum alloy plate, etc.
Why can't I start engraving when
pressing the button on the host

Questions
Solutions
What non-transparent materials can the
C1 Ultra laser engraver engrave or cut?
Engraving: cardboard, wood, bamboo, rubber, leather, cloth, acrylic, plastic, etc.;
Cutting: cardboard, wood, bamboo, cloth, leather, cloth, acrylic (transparent acrylic
cannot be cut), plastic, etc.
Can it be engraved on curved materials?
Yes, but the curvature of the material and the area of the engraved image should not
be too large, otherwise there will be slight deformation.
Can it be engraved on
reflective/transparent materials such
as ceramics/glass?
Yes, but before engraving, anti-reflective materials (such as laser colored paper, black
marker) need to be applied to the surface of the material to ensure the engraving
effect and prevent reflected light from damaging the laser module.
Why do materials of the same material
but different colors have very different
processing effects using the same
G-code file?
Materials of different colors have different optical properties and absorb and reflect
laser energy differently. When engraving materials of the same material but different
colors, it is recommended to set different powers and speeds in the software.
