Enclosed Bench CO2 Marker
Desktop CO2 Laser Marking Machine
A 30W, 40W or 60W CO2 marker in a self-contained bench cabinet. The Class 1 laser stays fully inside the enclosure, castors let the whole machine move between work areas, and the lifting column sets focus quickly for batch work on small parts.

Class 1 Enclosure
Class 1 Enclosure: Safety by Design
The laser never leaves the cabinet. That single decision is what allows the machine to sit on a bench in an office, a workshop or a school lab.
Fully Enclosed Beam
The Class 1 laser is sealed inside the body, so there is no open beam during marking and no need for a separate laser room.
Emergency Stop
A dedicated button cuts power and stops the machine immediately, protecting both the operator and the equipment.
Separate Power Control
The laser supply manages current and switching, while the galvanometer supply feeds the scanners only when they are needed, cutting wear and energy use.
Optional Fume Extraction
A smoke purifier can be fitted to draw away the fumes and dust that marking wood, leather and plastic produces, keeping the air clean.

Castors and Drawer
Built-in castors move the unit between rooms, and the integrated drawer keeps tools, fixtures and material samples tidy.
Scaled Lifting Column
Graduated marks on the column remove guesswork from height setting, so focus is quick and consistent between operators.
Continuous Duty
The laser module is rated for 24-hour continuous operation, so a bench cell can run a full production day without stopping.
Small Part Throughput
Batch Small Parts Without Re-Fixturing
The bench format is fast when parts repeat. Set the focus once, load the fixture and run the batch, rather than re-setting the machine for every piece.
- One fixture, many partsA nest or jig holds the batch, so the operator only loads and unloads rather than re-aiming the beam.
- Focus held by the columnThe scaled lifting column returns to the same height, which keeps depth identical from the first part to the last.
- Enclosed work areaThe Class 1 cabinet shields the surrounding workspace, so the operator can load the next part close to the machine.
- Fits a normal tableAt 600 x 775 mm the footprint sits on a standard bench, and castors allow it to be moved away when the space is needed.

What Comes Off the Bed
From signage blanks to personalised gifts, the desktop CO2 machine covers the small, precise work that a floor-standing unit would slow down.
Technical Data
Datasheet: KR-DC30, KR-DC40 and KR-DC60
The three models share a cabinet and a controller. Power and its electrical figures are what separate them.

The KR-DC60 offers a choice of air or water cooling, while the two lower models are air-cooled only. Dual laser operation is available on the KR-DC60; confirm the configuration against your part before production.
Operating Routine
Running a Batch on the Desktop
The cabinet arrives tested. From there, a batch job follows four simple movements.
01
Set the Height
Use the scaled column to bring the head to the focus height for your fixture and material.
02
Load the Fixture
Drop the jig or nest into the work area so every part in the batch sits in the same place.
03
Run the File
Start the program from the control panel and let the enclosed head mark each position in turn.
04
Unload and Repeat
Swap the finished parts out, reload the fixture and run again with the same settings.
Material Range
Wood, Acrylic, Leather and Coated Metal
The 10.6 μm wavelength is made for non-metal work, and it can also mark coated metal by removing the coating rather than cutting the metal itself.
A
Wood and Plywood
Clean engraving and crisp cut detail for signs, gifts and decorative panels straight off the bed.
B
Acrylic and Plastics
Frosted marks and edge-lit detail on acrylic, with parameters tuned per sheet to avoid crazing.
C
Leather and Coated Metal
Pattern and lettering on leather, plus high-contrast marks on painted and coated metal surfaces.
“We run personalised items in batches of a hundred or more. Because the fixture stays put and the column returns to the same height, the hundredth mark is identical to the first, and the enclosure means we can keep the bench in the shop itself.”

FAQ
Desktop CO2 Marking: Common Questions
Many beginners find the KR-DC40 a strong choice, because it is operator friendly, accurate and versatile enough for entry level laser marking projects.
It can handle wood and some metal engraving tasks. For faster, deeper engraving on metal, a more powerful model such as the KR-DC60 is recommended.
Yes. It is versatile, accurate and easy to use, which makes it a good fit for makers who work across several materials.
The dual laser option, available on the KR-DC60, brings faster throughput, higher accuracy and more flexibility when working with complex designs.
The machines are designed with safety in mind. The Class 1 laser is fully enclosed inside the cabinet, so there is no exposure risk, and they are suitable for use at home or in an office.
The key factors are laser power, precision and compatibility with the materials you use. The KR-DC30 suits finer work, while the KR-DC60 offers more power for demanding projects.
Always wear protective eyewear, make sure there is proper ventilation, train the operators, keep the machine guard in place and maintain the unit regularly.
It is well suited to etching acrylic, personalising gifts, making signs and engraving patterns on a range of materials, balancing speed and precision for small businesses.
Set the correct focus height, keep the work table level and check the beam path alignment regularly. If a problem appears, contact technical support for help.
Yes. LightBurn works with the KR-DC30, KR-DC40 and KR-DC60, giving strong design and control options for the desktop CO2 range.
